Description

Technical Field

[0001] The present invention relates to a physical property information retrieval system, a physical property information retrieval method and a storage medium storing a physical property information retrieval program. The physical property information retrieval system comprises: a processor; and a storage device storing a material information database, wherein the material information database stores information related to the material, and when a retrieval condition related to the material is obtained, information that meets the retrieval condition related to the material is obtained from the material information database, and the obtained information that meets the retrieval condition is output. Background Art

[0002] Correct physical property values ​​are important in most cases. For example, in order to design products so as to ensure the durability and safety of the products, the correct physical property values ​​of the materials are required. In addition, in materials informatics (MI: Materials Informatics) and process informatics (PI: Process Informatics), it is indispensable to use correct physical property values. In materials informatics and process informatics, if the physical property values ​​used are incorrect, it is difficult to obtain appropriate results. In addition, materials informatics refers to the general term for measures to efficiently and quickly explore and trial-produce new materials by analyzing the database of experimental and simulation results related to materials using information science (informatics) methods. In addition, process informatics refers to the general term for measures to efficiently search for and optimize the synthesis and manufacturing methods of materials, such as how to produce materials searched through materials informatics.

[0003] Furthermore, in order to obtain the correct physical property values, it is necessary to obtain the measurement data of the substance under appropriate measurement conditions, correctly interpret the measurement data, and correctly calculate the physical property values ​​based on the measurement data. In order to appropriately determine the measurement conditions and interpret the measurement data, the measurement data and measurement conditions of the substance measured in the past are often referred to.

[0004] Therefore, there is a technology that can efficiently collect measurement data and measurement conditions of substances measured in the past for reference in order to determine measurement conditions and interpret measurement data. For example, Patent Document 1 describes a research and development support system that retrieves and outputs information that supports research and development from a database that stores electronic experimental data output from a device used by a researcher in an experiment, graphs based on the experimental data, ideas related to research and development considered by the researcher, and notes related to the examination of experimental results.

[0005] However, even if the technique described in Patent Document 1 is used, the measurement data and measurement conditions of the substance measured in the past and referred to in order to determine the measurement conditions and interpret the measurement data are retrieved from the database. In the technique described in Patent Document 1, various information other than the measurement data and measurement conditions of the substance, such as graphs based on experimental data, ideas related to research and development considered by researchers, and notes related to the examination of experimental results, may be obtained along with the measurement data and measurement conditions of the substance. Therefore, even if the technique described in Patent Document 1 is used, there is a problem that it takes time to collect the measurement data and measurement conditions of the substance measured in the past and referred to in order to determine the measurement conditions and interpret the measurement data.

[0036] In this specification, etc., as examples of various information, sometimes the expression "XX table" is used for description, but it can also be expressed by a data structure such as "XX list" or "XX queue". In addition, "XX table" can also be set as "XX information".

[0037] (Example)

[0038] <<System Structure>>

[0039] Figure 1 FIG. 2 is an example of a functional block diagram of the physical property information retrieval system 1 in the embodiment. Figure 1 As shown, the physical property information retrieval system 1 is connected to the user terminal 500 and the measurement control device 610 via the network NW. The physical property information retrieval system 1 is constructed on a server in a cloud environment. The physical property information retrieval system 1 may also be constructed on a server in a local environment.

[0040] The user terminal 500 and the measurement control device 610 are devices used by a user who searches for information on a substance. The user terminal 500 and the measurement control device 610 can transmit and receive information to and from the physical property information retrieval system 1 via the network NW.

[0041] The user terminal 500 is a personal PC or the like. The measurement control device 610 is a device for controlling the measurement device 600. The measurement control device 610 causes the measurement device 600 to perform measurement based on the measurement conditions and generates continuous measurement data such as a spectrum. In addition, the continuous measurement data measured using the measurement device 600 is stored. In addition, the measurement device 600 is, for example, a measurement device for chromatography, capillary electrophoresis, photoelectron spectroscopy, infrared absorption spectroscopy, nuclear magnetic resonance spectroscopy, fluorescence spectroscopy, fluorescent X-ray spectroscopy, visible-ultraviolet absorption spectroscopy, Raman spectroscopy, atomic absorption spectrometry, flame luminescence spectroscopy, luminescence spectroscopy, X-ray absorption spectroscopy, X-ray diffraction, electron spin resonance spectroscopy, mass spectrometry, etc.

[0042] The network NW may be a wired network or a wireless network. Furthermore, the network NW may be a global network such as the Internet or a local area network (LAN).

[0043] The physical property information search system 1 includes a storage device 23 , a transceiver 11 , and a processing unit 12 . The storage device 23 stores a substance information database 231 . The substance information database 231 stores information related to substances. The transceiver 11 transmits and receives data to and from the user terminal 500 and the measuring device 600 .

[0044] The processing unit 12 includes a search unit 121 and a data registration unit 122 .

[0045] The search unit 121 acquires information that meets the search condition from the substance information database 231 , and outputs the information to the transmitter-receiver unit 11 .

[0046] The data registration unit 122 allows the user of the user terminal 500 to input data to be stored in the substance information database 231 using the knowledge graph, and stores the data input using the knowledge graph in the substance information database 231 .

[0047] When the search condition is transmitted from the user terminal 500 or the measurement control device 610 to the physical property information retrieval system 1, the transceiver 11 obtains the search condition and outputs the obtained search condition to the retrieval unit 121. The retrieval unit 121 obtains information consistent with the search condition obtained from the transceiver 11 from the substance information database 231, and outputs it to the transceiver 11. Then, the transceiver 11 replies the information consistent with the search condition obtained from the retrieval unit 121 to the user terminal 500 or the measurement control device 610 that transmitted the search condition.

[0048] When the user terminal 500 or the measurement control device 610 sends information indicating that the information is to be stored in the material information database 231 to the physical property information retrieval system 1, the data registration unit 122 replies with a template of physical property case information in the form of a knowledge graph. When the user terminal 500 or the measurement control device 610 inputs information to be stored in the material information database 231, the user terminal 500 or the measurement control device 610 sends the information to be stored in the material information database 231 to the physical property information retrieval system 1. The physical property information retrieval system 1 stores the received information to be stored in the material information database 231 in the material information database 231.

[0049] <Hardware Configuration of Physical Property Information Retrieval System 1>

[0050] Figure 2 1 is a block diagram showing an example of the hardware configuration of the physical property information retrieval system 1. Figure 2 As shown, the physical property information retrieval system 1 includes a processor 21, a main storage device 22, a secondary storage device 23, an input device 24, an output device 25, a network I / F 26, and a bus 27 connecting them.

[0051] The physical property information retrieval system 1 can be realized by a general information processing device such as a PC or a server computer. The user terminal 500 and the measurement control device 610 can also be realized using the same hardware resources as the physical property information retrieval system 1 .

[0052] The processor 21 reads data and programs stored in the secondary storage device 23 to the primary storage device 22 and executes processing determined by the program.

[0053] The main storage device 22 is a RAM or the like, has a volatile storage element, and stores programs and data executed by the processor 21 .

[0054] The secondary storage device 23 is a HDD (Hard Disk Drive) or SSD (Solid State Drive), etc., and has a non-volatile storage element, and stores programs, data, etc. The secondary storage device 23 stores a substance information database 231 and a physical property example information database 232, which will be described in detail later. The substance information database 231 stores data on substances. The physical property example information database 232 stores a template for the records of the substance information database 231 used when the data registration unit 122 registers data (records) in the substance information database 231.

[0055] In addition, a search program 121a and a data registration program 122a are installed in the secondary storage device 23. Figure 1 The search unit 121 and the data registration unit 122 described above are realized by the processor 21 reading the search program 121a and the data registration program 122a stored in the secondary storage device 23 to the primary storage device 22 and executing them. The processor 21 is the processing unit 12.

[0056] The input device 24 is a device such as a keyboard and a mouse that receives user operations and acquires information input by user operations. The output device 25 is a device such as a display that outputs information and presents information to the user by displaying it on a screen, for example.

[0057] The network I / F 26 is an interface for transmitting and receiving data with a device such as a user terminal 500 via the network NW. That is, the network I / F 26 is a transceiver capable of transmitting and receiving information with the user terminal 500 via the network NW. The physical property information retrieval system 1 can transmit and receive data with a device such as a user terminal 500 connected to the network NW using the network I / F 26.

[0058] <Structure of substance information database 231>

[0059] The material information database 231 stores physical property case information that associates material identification information that identifies a material with at least one measurement record data, which is a combination of continuous measurement data for the material, information on measurement conditions for the measurement data, physical property values ​​calculated from the measurement data (referred to as "measured physical property values"), and measurement data characteristic information that indicates characteristics of the measurement data. The physical property case information may include material identification information and information other than material identification information, such as a method for manufacturing the material and information on a document in which the measurement data is recorded.

[0060] The physical property example information stored in the substance information database 231 is data for one substance.

[0061] The substance identification information is information that identifies a substance that can be a measurement object, such as a pure substance, an inorganic compound, an organic compound, or a resin. The substance identification information is, for example, the name of the substance. The substance identification information may also be a list of IUPAC names and customary names for the substance. In addition, when the substance is a mixture such as a resin, the physical property identification information may also be the composition of the resin material.

[0062] The continuous measurement data for a substance may be, for example, measurement data of a chromatogram such as HPLC or gas chromatography. The measurement data may also be measurement data of electrophoresis such as capillary electrophoresis or two-dimensional electrophoresis. The measurement data may also be measurement data of spectroscopic measurement methods such as photoelectron spectroscopy, infrared absorption spectroscopy, nuclear magnetic resonance spectroscopy, fluorescence spectroscopy, fluorescence X-ray spectroscopy, visible-ultraviolet absorption spectroscopy, Raman spectroscopy, atomic absorption spectrometry, flame luminescence spectroscopy, luminescence spectroscopy, X-ray absorption spectroscopy, X-ray diffraction, electron spin resonance spectroscopy, one-dimensional NMR, two-dimensional NMR, etc. The measurement data may also be measurement data of mass spectrometry, etc. The measurement data may also be measurement data of thermal analysis such as DSC, etc. In addition, the measurement data may also be image data of AFM or image data of SEM.

[0063] The information on the measurement conditions of the measurement data includes information on parameters set in the measurement and also includes information on the measurement method.

[0064] The measured physical property value is, for example, the position of a peak or the intensity of a peak in continuous measurement data of a substance.

[0065] The measurement data characteristic information includes at least one value representing the shape characteristics of the measurement curve that can be calculated from the measurement curve by numerical analysis and is independent of the interpretation of the measurement curve produced by plotting the measurement data. In addition, it is preferred that the value included in the measurement data characteristic information is a value that does not represent the physical property of the substance of the measurement object of the measurement data.

[0066] The measurement data characteristic information of this embodiment is, for example, a shape feature vector that is a combination (in vector form) of information determining the peak value (peak position (value of the horizontal axis)), the prominence of the peak value, and the width of the peak value for a measurement curve produced by plotting the measurement data and a differential measurement curve obtained by differentiating the measurement curve. The information determining the peak value can be calculated based on the measurement data using a known algorithm. In addition, the measurement curve can also be smoothed, and the shape feature vector can be calculated based on information for determining the peak value of the smoothed measurement curve and information for determining the peak value of the differential measurement curve of the smoothed measurement curve.

[0067] The information for determining the peak value includes data relative to the peak value having extreme values ​​(maximum value and minimum value). That is, in the peak detection result, the value of the horizontal axis (for example, temperature in the case of differential scanning calorimeter (DSC)) relative to the two peak values, namely, the peak value having a maximum value protruding upward and the peak value having a minimum value concave downward, the protrusion degree of the peak value, and the width of the peak value are calculated.

[0068] Figure 3 This is an explanatory diagram for explaining the prominence of a peak and the width of a peak. The prominence of a peak refers to the height of the position where the height (intensity) of the peak apex (extreme value) is the smallest in the moving path when the apex (extreme value) of the peak moves on the measurement curve to a vertex (extreme value) higher (stronger) than the apex (extreme value) of the peak relative to the apex (extreme value). When the height (intensity) of the apex (extreme value) of the peak is the largest (or smallest) in the measurement curve, the prominence of the peak is set to the height (intensity) of the apex (extreme value) of the peak relative to the baseline.

[0069] exist Figure 3 In the graph, at peak 1, the prominence of the peak is p1, and the width of the peak is w1. Similarly, at peak 2, the prominence of the peak is p2, and the width of the peak is w2. In addition, at peak 3, the prominence of the peak is p3, and the width of the peak is w3.

[0070] Since the measured curve intersects with Peak 2 at the minimum value c (needs to be reduced to the minimum value c), the protrusion of Peak 1 is p1. Regarding the protrusion of Peak 2, since the measured curve intersects with Peak 3 (a peak higher than Peak 2) at the minimum value b, the protrusion is p2. The maximum value of Peak 3 is the maximum value, so the protrusion is p3. The width of the peak is set to the width of half the protrusion.

[0071] <<Process>>

[0072] Next, the processing of the physical property information retrieval system 1 is described. As described above, the retrieval unit 121 retrieves information that meets the retrieval condition from the material information database 231. The data registration unit 122 receives input of information related to a substance to be registered in the material information database 231 using a graph in the form of a knowledge graph, and stores the input information related to the substance in the material information database 231.

[0073] Hereinafter, first, storage of information on substances by the data registration unit 122 will be described, and then an example of search by the search unit 121 will be described.

[0074] <1. Save information related to the substance in the substance information database 231, Figures 4 to 9 >

[0075] The user operates the user terminal 500 or the measurement control device 610 to make the user terminal 500 or the measurement control device 610 access the physical property information retrieval system 1. When the physical property information retrieval system 1 is accessed by the user terminal 500, the data registration unit 122 transmits the condition input screen information to the user terminal 500.

[0076] The data registration unit 122 obtains a template of physical property example information to be stored in the material information database 231 from the physical property example information database 232, and converts the obtained template of the physical property example information into a knowledge graph format. Then, the data registration unit 122 generates physical property example information input screen information, which includes: information on the structure of the physical property example information input screen including the template information of the physical property example information in the knowledge graph format, and information on the meaning of causing the user terminal 500 or the measurement control device 610 to display the physical property example information input screen. The physical property example information input screen (see Figure 5A as well as Figure 5B ) displays a template of physical property example information in the form of a knowledge graph, and accepts input of physical property example information. Furthermore, the data registration unit 122 causes the transceiver unit 11 to send the generated physical property example information input screen information to the user terminal 500 or the measurement control device 610. The following describes the expression method in the form of a knowledge graph of this embodiment. Next, an example of a physical property example information input screen is described.

[0077] As described above, the data registration unit 122 generates a physical property instance information knowledge graph information in which the template of the physical property instance information is set to the knowledge graph form, and outputs the physical property instance information knowledge graph information to the user terminal 500 and the measurement control device 610. When the physical property instance information generated based on the physical property instance information knowledge graph information is obtained, the obtained physical property instance information generated based on the physical property instance information knowledge graph information is saved in the material information database 231.

[0078] <Knowledge graph representation method>

[0079] Figure 4 : is an explanatory diagram for explaining the method of expressing the knowledge graph form of this embodiment. The method of expressing the knowledge graph form of this embodiment is a knowledge graph form that introduces the expression method used in the class diagram of UML (UNL: Unified Modeling Language). Figure 4 As shown, as a method of expressing the UML class diagram incorporated into the knowledge graph, category 401, category name 402, instance, attribute and attribute value 403, relationship 404, association name 405, reuse 406, generalization relationship 407, box 408, and box name 409 are used.

[0080] In the knowledge graph of this embodiment, "category" and "instance" are used as nodes. The category functions as a "template". Specific information input using the category is called an "instance". Figure 4 A knowledge graph is shown where nodes represent "categories".

[0081] like Figure 4 As shown, a category represents a concept such as "material" or "product". A category is represented by a rectangular box. A rectangular box representing a category 401 is divided into a partition containing a category name 402 and a partition containing an attribute list. Attributes and attribute values ​​403 are combinations of attributes and attribute values. Attributes are properties of a category. Attribute values ​​are values ​​for attributes. Figure 4 As shown, for example, category 401 is a category whose category name 402 is "material". The attribute and attribute value 403 included in the attribute list of category 401 are "material name" and the attribute value is "character string (name of specific material)".

[0082] In addition, in the knowledge graph of the present embodiment, arrows 404 representing relationships (edges) 404 are drawn between multiple categories that have significant relationships with each other. The knowledge graph of the present embodiment uses arrows 404 connecting multiple categories to indicate that multiple categories have significant relationships with each other. The association name 405 indicates what the multiple categories connected by the arrows mean. Usually, the association name 405 is a verb that indicates what kind of behavior the multiple related categories perform. The reuse degree 406 indicates that in the relationship between multiple categories shown by the relationship (arrow) 404, for the category on one side of the arrow 404, the number of categories on the other side of the arrow (the relationship represented by the arrow) is limited.

[0083] The generalization relationship (inheritance) 407 indicates that the general category (parent category) and the special category (child category) relative to the general category (parent category) have a generalization-specialization (general-special) relationship. The generalization relationship (inheritance) 407 is represented by an arrow 407 with a triangle located on the parent category side.

[0084] The frame 408 represents a node group formed by grouping a plurality of nodes that can be grouped together in a concept. The frame 408 is represented by a rectangle surrounding a plurality of nodes that can be grouped together in a concept. The frame name 409 is drawn at the upper left portion of the rectangle representing the frame.

[0085] The attributes and attribute values ​​403 , relations 404 , association names 405 , reuse degrees 406 , generalization relations 407 , and boxes 408 described above are also used in the knowledge graph in which a node represents an “instance (specific information of a category)”.

[0086] <Example of the property case information input screen>

[0087] Figure 5A 1 is a diagram showing an example of a physical property example information input screen 500A. Figure 5A This is an example of a physical property example information input screen 500A for generating and storing physical property example information of a new substance and its measurement data. Figure 5A The physical property example information input screen 500A includes a substance identification information box 501, a measurement information box 502, and an analysis information box 503. These boxes are reduced and expanded when clicked. The substance identification information box 501 includes a "material type" for inputting substance identification information.

[0088] The measurement information box 502 and the analysis information box 503 are at least one measurement record information, which is a combination of measurement data on the continuity of the substance, information on the measurement conditions of the measurement data, measurement property values ​​calculated based on the measurement data, and measurement data characteristic information representing the characteristics of the measurement data.

[0089] In the measurement information box 502, there are categories of information for inputting measurement conditions of measurement data. The measurement information box 502 includes "category of sample piece" for inputting sample information, "category of measurement" for inputting information of measurement environment, "category of measurement device" for inputting information of measurement device, "category of measurement curve" for inputting measurement data, and "category of measurement condition" for inputting information of measurement conditions.

[0090] The analysis information box 503 includes a type of input for measuring physical property values ​​calculated from the measurement data and a type of input for measuring data characteristic information representing the characteristics of the measurement data. The analysis information box 503 includes a "type of characteristic" for inputting the measurement physical property values ​​and a "type of shape feature" for inputting the measurement data characteristic information.

[0101] <2. Example of search using substance information database 231, Figure 10 to Figure 17 >

[0102] Fig.10 1 is an explanatory diagram for explaining the screen transitions for setting search conditions and displaying search results. In the physical property information retrieval system 1, search condition setting and search result display are performed through a GUI (Graphical User Interface). Fig.10As shown, for example, a search condition (material information search condition) including at least one of the information including thermal property information, sample information, measurement information, material identification information such as shape feature vectors, measurement data, information included in information on measurement conditions of measurement data, information included in measurement data characteristic information, and information included in physical property information is input into the material information search condition input screen 1010. The information on the material information search condition input screen 1010 is transmitted from the physical property information search system 1 to the user terminal 500 or the measurement control device 610. When the user terminal 500 or the measurement control device 610 transmits the material information search condition inputted into the user terminal 500 or the measurement control device 610 using the material information search condition input screen 1010 to the physical property information search system 1, the search unit 121 searches the material information database 231, obtains material instance information that meets the material information search condition, and causes the transceiver 11 to output (transmit) the material instance information that meets the material information search condition obtained by the information search unit to the user terminal 500 or the measurement device 600. Thus, as Figure 12 to Figure 17 As shown, the user terminal 500 or the measurement device 600 displays substance instance information.

[0103] The following is a detailed description. Fig.11 This is an example of the substance information search condition input screen 1010 . Fig.12 , Fig.13A as well as Fig. 13B This is an example of a search result list screen 1020 that displays a list of search results. Fig.14 This is an example of a measurement record screen 1030 showing a measurement curve, measured physical property values, and measurement data characteristic information. Fig.15 This is an example of the analysis example display screen 1041 . Fig.16 This is an example of the measurement information display screen 1042 . Fig.17 This is an example of the calculation condition display screen 1043. Hereinafter, each screen will be described in detail.

[0104] Fig.11 The material information search condition input screen 1010 shown has: a thermal property input area 1110, which accepts input of thermal property information; a material identification information input area 1120, which inputs material identification information; a measurement condition input area 1130, which inputs information on measurement conditions; a measurement result input area 1140, which inputs measured property values ​​and measurement data characteristic information; and a search start button 1150, which, when pressed, sends the material information search conditions input into the material information search condition input screen 1010 to the physical property information retrieval system 1.

[0105] When the attribute of the characteristic registered in the thermophysical property information is selected by a pull-down, the thermophysical property input area 1110 displays an input box corresponding to the type of attribute value. For example, when the attribute is a thermophysical property (1111), the type of attribute value is set to select the classification of the attribute value from the registration list, and the input box of the attribute value is set to select items such as melting, crystallization, enthalpy relaxation, etc. by a pull-down. When the attribute is a substance (1112), the type of attribute value is set to a string, and the input box of the attribute value is set to input a string for keyword search. When the attribute is a peak temperature (1113), the type of attribute value is set to a numerical value, and the input box of the attribute value is set to a search range for inputting a numerical value. When the attribute is specified by a pull-down and the attribute value is set to a blank column (1114), the attribute is not used for the search condition, but the attribute value is displayed in the search result list. When the add button 11115 configured in the input area is clicked, the drop-down for attribute selection is added. When the delete button 1116 is clicked, the drop-down for attribute selection and the input box for attribute value are deleted. The sample information input area and the measurement information input area have the same structure.

[0106] Next, the measurement result input area 1140 is described in detail. When the measurement curve input button 1141 is clicked, another screen for selecting the measurement curve is displayed. When a measurement curve is selected in this screen, the selected measurement curve and its differential measurement curve, and the respective peak detection results are displayed. If a check mark 1142 is added to the column on the left end of the table of the peak list of the measurement curve, the peak is selected, and the characteristic vector (temperature, protrusion, width) is registered in the column 1143 of the characteristic value of the detection condition of the peak contained in the measurement curve. The user refers to the value of the characteristic vector and enters a numerical value in the column of the lower limit 1144 and upper limit 1145 of the retrieval of the characteristic vector. For the differential measurement curve, the peak of interest is selected in the same order, and the retrieval range of the characteristic vector is entered. When the search start button 11150 at the bottom of the screen is clicked, the material information retrieval condition input into the material information retrieval condition input screen 1010 is sent to the physical property information retrieval system 1, and the material information retrieval condition and the AND search are performed.

[0107] Fig.12 The search result list screen 1020 for displaying a list of search results is shown in FIG. 1020. The items in each column of the result list are assigned to Fig.11 The properties are inputted in the material information search condition input screen 1010 shown in FIG. The property values ​​of the retrieved measurement curve are displayed in each row. When the display button 1201 arranged at the left end of the list is clicked to confirm the details of the retrieved measurement curve, the details of the measurement curve are displayed in another screen.

[0108] In addition, default display items are set for samples and thermal properties. When a sample contains multiple materials, all materials are displayed in a list. When a measurement curve contains multiple thermal properties, all thermal properties are displayed in a list. The user specifies display items other than the default display items by inputting search conditions. For example, if you want to display the peak temperature of a thermal property, you can set the peak temperature by pulling down. If you want to confirm the details of the property information contained in the displayed measurement curve, when you click the display button 1201 arranged at the left end of the list, the measurement information display screen (see Fig.16 ) The details of the measurement curve are displayed in . In addition, when the save button 1202 is clicked, a file save screen (not shown) is displayed, and then a file format such as csv is specified to save the search result list.

[0109] Fig.13A and Fig. 13B FIG. 1 is an example of a search result list screen 1020 showing a list of search results. Fig.13A as well as Fig. 13B As shown in FIG. 13A , various functions can be added to the search result list screen 1020. Fig. 13B The search result list screen 1020 shown is an example in which a similarity calculation function of a shape feature vector is added.

[0110] As the similarity, the norm distance between the shape feature vector of the input measurement curve and the shape feature vector of the retrieved measurement curve can be used. In addition, the calculation can be performed by giving a weight to the vector component of interest. Fig.13A The search results before similarity calculation are shown. A row 1301 for setting weights of vector components is provided, and weights are set. Components whose weights are set to 0 are not used for norm distance calculation. When the normalization button 1302A is clicked, normalization of each vector component and calculation of norm distance are performed, switching to the normalization mode. Fig. 13B screen.

[0111] The normalized vector components and norm distances are displayed. A sort button 1303 is configured in each column. When the sort button for norm distance is clicked, the columns are sorted in the order of the norm distance from the smallest to the largest. In addition, the sort button for each vector component can be used to check for abnormal values, etc. If you want to return to the weighted setting, click the measured value button 1302B to return to the normalized setting. Fig.13A screen.

[0112] Fig.14The measurement record screen 1030 showing the measurement curve, the measured property value and the measurement data characteristic information is provided with a display area 1410 for the measurement curve and the differential measurement curve, and a display area 1420 for the thermal characteristic attribute. In the display area 1420 for the thermal characteristic attribute, all the thermal properties, substances, property values ​​and explanations associated with the measurement curve are displayed. For example, the overview display only shows the peak temperature, but if the peak area (melting entropy), the start temperature of the peak, the end temperature, and the explanation for the peak are registered, they are displayed. The peak and the step are given an ID, and the position of the peak and the step is indicated by an arrow 1403 in the chart area.

[0113] Furthermore, when the melting entropy is calculated as the total value of a plurality of peaks, the calculated value of the melting entropy is displayed in the row of the main peak, and the IDs of the plurality of peaks used for the calculation are displayed in the explanation column ( 1404 ).

[0114] In addition, when the shape feature vector is selected in the search condition, the measurement curve (dashed line) input together with the searched measurement curve (solid line) is displayed in the display area 1410 of the measurement curve and the differential measurement curve. When the analysis case display button 1405 at the bottom of the screen is clicked, the analysis case display screen 1041 including the measurement curve is displayed as another screen (see Fig.15 ), when the measurement information display button 1406 is clicked, the measurement information display screen 1042 is displayed as another screen (refer to Fig.16 ), when the calculation condition display button 1407 is clicked, the calculation information display screen 1043 is displayed on another screen (refer to Fig.17 ).

A plurality of measurement curves including the selected measurement curve are displayed in the graph 1502 of the analysis example. An explanation obtained by comparing a plurality of measurement curves is displayed in the explanation 1504 of the analysis example. If more detailed information on the analysis example is desired, a manual recording the analysis example is displayed by clicking a reference button 1505.

[0116] exist Fig.16 In the example of the measurement information display screen 1042 shown, a display area 1601 for measurement device attributes and a display area 1602 for measurement condition attributes are provided. The attributes of the measurement device that affect the DSC measurement include the type of device used (device manufacturer, device model, analysis mode, etc.), the type of sample disk, the material and mass of the reference sample, etc. These attributes are displayed in a table format in the display area 1601 for measurement device attributes.

[0117] The heating mode, gas type, etc. are displayed in the display area 1602 of the measurement condition attributes. The heating mode is displayed not only in a table but also in a graph. In the case of thermal analysis, the measurement curve changes according to the thermal history of the sample, so it is necessary to set the heating mode not only when measuring the measurement curve, but also before the measurement.

[0118] As a heating mode, after the first heating (run 1) and cooling (run 2), the second heating (run 3) and cooling (run 4) are set, and all runs are displayed. When the run for which the measurement curve is obtained is run 3, the part of run 3 is displayed with a thick line 1603 and a bold font 1604. As a heating mode, several modes such as ramp (inclination), step, and single-frequency vibration are set. When the mode is a ramp, the start temperature, end temperature, temperature change rate, holding time, etc. are displayed.

[0119] The user confirms the measurement device attributes and measurement condition attributes, makes corrections as needed, and saves the measurement information. When the save button 1605 is clicked, a file save screen (not shown) is displayed. The measurement conditions are saved by specifying the file format. If the format of the measurement condition setting file of the measurement device is supported, it is saved in that format. If it is not supported, it is saved in a general format such as csv format.

[0120] exist Fig.17 In an example of the calculation information display screen 1043 shown, there is a display area 1701 for the measurement curve and the differential measurement curve, and a display area 1702 for the calculation conditions and calculation results. In DSC, it is necessary to set the baseline type, starting point and end point, etc. In the display area 1701 for the measurement curve and the differential measurement curve, the positions of the starting point and the end point of the baseline are indicated by a + mark 1703, and the baseline 1704 is indicated by a line segment or a curve. In the display area 1702 for the calculation conditions and calculation results, the calculation results are displayed together with the baseline type, the starting point and the end point. In order to identify which peak or step the calculation conditions are set for, an ID is added to the peak or step and displayed in a chart and a table. The user confirms the calculation conditions and the calculation results and saves the calculation conditions. When the save button 1705 is clicked, a file save screen (omitted in the figure) is displayed. Specify the file format and save the calculation conditions. If the format of the calculation condition setting file of the analysis software for the measurement curve is supported, it is saved in this format. If it is not supported, it is saved in a general format such as csv format. The user sets the calculation conditions of the analysis software by referring to the output csv file, and executes the calculation of the thermophysical properties.

[0121] <Effects of the Invention>

In addition, the processing unit 12 (search unit 121) can obtain and output physical property example information that matches the material information search condition from the material information database 231. The physical property example information includes at least one measurement record information in a combination of the measurement data of the material and the information of the measurement conditions, the measurement data characteristic information indicating the characteristics of the measurement data, and the physical property information calculated based on the measurement data.

[0123] Therefore, it is easy to use the measurement data, measurement conditions, and characteristics of the measurement data stored in the material information database.

This information does not depend on the interpretation of the measurement data, and therefore clearly indicates the characteristics of the shape of the measurement data. As a result, the user can easily obtain the desired measurement data.

[0128] In addition, the data registration unit 122 generates a physical property instance information knowledge graph information in which the template of the physical property instance information is set to the knowledge graph form, and outputs the physical property instance information knowledge graph information to the user terminal 500 and the measurement control device 610. When the physical property instance information generated based on the physical property instance information knowledge graph information is obtained, the obtained physical property instance information generated based on the physical property instance information knowledge graph information is stored in the material information database 231.
