The data extraction unit 42 extracts unstructured data as structured data candidates from the unstructured data stored in the entire data storage unit 44. The data conversion unit 40 converts the structured data candidates extracted by the data extraction unit 42 into structured data, and stores the structured data in the structured data storage unit 38. Unstructured data is, for example, charts and graphs, experimental condition information, etc. When an electronic experiment notebook described later is used as the entire data storage unit 44, the unstructured data is all the data stored in the electronic experiment notebook.

[0058] A data lake may also be used as the entire data storage unit 44. A data lake is a repository that can uniformly manage and store data collected from various sources. A repository refers to a data storage repository or storage library. Commercial data lakes such as Snowflake (registered trademark) and Databricks (registered trademark) may be used as data lakes. In addition, data lakes such as HADOOP (registered trademark) developed and released by the open source software community Apache Software Foundation may also be used.

[0059] Fig.14 is an example of effective use of data using a data lake. Fig.14In the data lake 601, text data, image data, and sound data are accumulated, and ETL is performed on the accumulated data and saved as structured data in the database 602. ETL is to extract (Extract) necessary data from the data accumulated in the database, etc., transform (Transform) according to the purpose, and store (Load) the data into the required system. As ETL tools, there are Pipeline Pilot provided by Dassault Systemes or Informatica (registered trademark) provided by Informatica Japan. The data saved as structured data is visualized and analyzed. When using Fig.14 When the data lake 601 is used as the entire data storage unit 44, the structured data storage unit 38 is equivalent to Fig.14 Database 602.

[0060] An electronic experiment notebook may be used as the entire data storage unit 44. The electronic experiment notebook is a system that can record various information related to experiments as digital data and effectively utilize them. The electronic experiment notebook can use the commercial electronic experiment notebook BIOVIA Notebook provided by BIOVIA.

[0061] Fig.15 This is an example of effective use of data from an electronic lab notebook. Fig.15 In the electronic experiment notebook 603, text data, image data, and sound data are accumulated, and ETL is performed on the accumulated data and saved as structured data in the database 604.

The operation receiving unit 52 receives the user's operation such as the input of information. The request sending unit 54 sends a request for processing corresponding to the information input from the user to the information search device 10. In addition, the response receiving unit 56 receives a response to the request for processing sent by the request sending unit 54 from the information search device 10.

[0063] The request receiving unit 20 receives a request for processing from the user terminal 12. The response sending unit 22 sends a response of a processing result according to the request for processing.

[0064] The search expression acquisition unit 24 acquires a search expression for specifying structured data to be graphed by a graph drawing unit 34 described later, based on a search condition specified by a user. The search expression acquisition unit 24 sends the acquired search expression to the search expression matching data acquisition unit 32 .

[0065] The search expression matching data acquisition unit 32 acquires structured data matching the search expression acquired by the search expression acquisition unit 24 from the structured data storage unit 38. The search expression matching data acquisition unit 32 sends the acquired structured data to the information display unit 50.

[0066] The information display unit 50 displays the acquired structured data in a table format on the display device 502 .

[0067] The graph display item acquisition unit 26 acquires graph display items of a graph to be drawn by the graph drawing unit 34 described later, based on information specified by the user. Examples of the graph display items include the type of characteristics of the display object on the horizontal axis (X axis) of the graph, the type of characteristics of the display object on the vertical axis (Y axis) of the graph, and the type of characteristics of the display object on the Z axis of the graph displayed as a color bar. The graph display item acquisition unit 26 sends the acquired graph display items to the graph drawing unit 34.

[0068] The graph drawing unit 34 draws the structured data acquired by the search expression matching data acquisition unit 32 as a graph based on the graph display items acquired by the graph display item acquisition unit 26. If the user does not specify a graph display item, the graph is drawn based on the default graph display item. The graph drawing unit 34 sends the drawn graph to the information display unit 50.

[0069] The information display unit 50 displays the acquired graph on the display device 502 .

[0070] The graph extraction range acquisition unit 28 acquires the graph extraction range specified by the user. The graph extraction range data acquisition unit 36 ​​extracts structured data corresponding to one or more data points included in the graph extraction range acquired by the graph extraction range acquisition unit 28 from the structured data storage unit 38. Then, the graph extraction range data acquisition unit 36 ​​creates and acquires a table including structured data including the extracted data points and links to unstructured data. The acquired structured data is sent to the information display unit 50.

[0071] The information display unit 50 displays the acquired table on the display device 502. The displayed table includes hyperlinks associated with the unstructured data.

[0073] The information display unit 50 displays the acquired unstructured data on the display device 502 .

[0074] In this way, users can access unstructured data associated with structured data based on the structured data to be analyzed, and can effectively utilize unstructured information such as charts, graphs, or experimental condition information contained in the unstructured data in material development, etc.

[0075] It should be noted that Figure 3 The structural diagram of is an example. The structure of the information processing system according to the present embodiment can be realized by various structures.

[0076] <Information Retrieval Method>

[0077] The steps of the information search method performed using the information search device of the present invention will be described in detail.

[0078] Figure 4 This is a flowchart showing an example of the information search method according to the present embodiment.

[0079] In step d1, an input of a search condition is received at the user terminal 12. The search expression acquisition unit 24 of the information search device 10 acquires a search expression.

[0080] Figure 6 and Figure 7 This is a diagram showing an example of a search expression input screen.

[0081] For example, the user selects the Figure 6 Enter the search expression on the search expression input screen. Figure 6 In the search expression input screen 1000 of , a mode for limiting the range is selected in the selection mode in the upper right corner, so that the user can input the characteristic value and the maximum and minimum values ​​included in the structured data to be analyzed. Figure 6 , select Physical Property B from the drop-down menu and enter 0.0 for the Minimum value and 60.0 for the Maximum value.

[0082] exist Figure 7 In the search expression input screen 1500 of , a mode for limiting candidates is selected in the selection mode in the upper right corner, and the user is prompted to input an evaluation category for the characteristic value. Figure 7, select "Physical property D" from the pull-down menu, and select "Yes" or "No" as the evaluation category from "Yes", "No", "Other", etc.

[0083] In step d2, the search expression matching data acquisition unit 32 of the information search device 10 acquires structured data matching the search expression acquired by the search expression acquisition unit 24 in step d1 from the structured data storage unit 38. The search expression matching data acquisition unit 32 transmits the acquired structured data to the information display unit 50, and the information display unit 50 displays the acquired structured data in a table format on the display device 502.

[0084] In step d3 , the graph drawing unit 34 of the information search device 10 draws a graph of the structured data acquired by the search expression matching data acquisition unit 32 in step d2 based on the graph display items designated by default. The graph drawing unit 34 sends the drawn graph to the information display unit 50 .

[0085] The information display unit 50 of the user terminal 12 displays the drawn graph.

[0086] Figure 8 is a diagram of an example of a graph that is drawn. Figure 8 In FIG. 1 , an example of a graph is shown in which the horizontal axis is plotted as “Characteristic A”, the vertical axis is plotted as “Characteristic B”, and the color bar is plotted as “Characteristic C” based on the default specification.

[0087] In step d4, input of a graph display item is accepted in the user terminal 12. The graph display item acquisition unit 26 of the information search device 10 acquires the graph display item.

[0088] Fig. 9 This is a diagram showing an example of a display item input screen for a graph. Fig. 9 The graph display item input screen 2000 is an example of a screen that allows the user to input display items of the horizontal axis, vertical axis, and color bar when drawing a graph. Fig. 9 In the chart display item input screen 2000, select a display item for the horizontal axis from the drop-down menu below the "horizontal axis" character string, select a display item for the vertical axis from the drop-down menu below the "vertical axis" character string, and select a display item for the color bar from the drop-down menu below the "color bar" character string.

[0089] In step d5, the graph drawing unit 34 of the information search device 10 redraws the structured data obtained in step d2 into a graph based on the graph display items obtained by the graph display item obtaining unit 26 in step d4. The information display unit 50 of the user terminal 12 displays the redrawn graph. If the display item is not input in step d4, the graph is not redrawn.

[0090] Fig.10 This is an example of a graph redrawn based on the graph display items acquired in step d5. "Characteristic E" is selected for the horizontal axis, "Characteristic B" is selected for the vertical axis, and "Characteristic F" is selected for the color bar.

[0091] It is also possible to return to step d1 according to the user's judgment based on the graphs displayed in steps d3 and d5.

[0092] In step d6, an input of a graph extraction range is received at the user terminal 12. The graph extraction range acquisition unit 28 of the information search device 10 acquires the graph extraction range.

[0093] Fig.11 This is a diagram showing an example of a graph drawing screen in which the graph extraction range is specified. Fig.11 In the graph drawing screen 4000, the four data points enclosed by the dotted line rectangle in the upper right corner are designated as the graph extraction range. Regarding the four data points enclosed by the dotted line rectangle, although the four data points are extracted as characteristics B and characteristics E, structured data including multi-dimensional information up to characteristics F and above is designated as the extraction range.

[0094] In step d7, the graph extraction range data acquisition unit 36 ​​of the information search device 10 acquires the structured data included in the graph extraction range acquired by the graph extraction range acquisition unit 28 in step d6 from the structured data storage unit 38. The structured data included in the graph extraction range can also be acquired from the structured data acquired in step d2. The graph extraction range data acquisition unit 36 ​​creates and acquires a table including the structured data including the extracted data points and the links to the unstructured data. The graph extraction range data acquisition unit 36 ​​sends the acquired table to the information display unit 50.

[0095] In step d8 , the information display unit 50 of the user terminal 12 displays the acquired table.

[0096] In step d9, the user's selection of a hyperlink included in the displayed table is accepted. The unstructured data processing unit 30 of the information search device 10 obtains the link selected by the user.

[0097] Fig.12 is a diagram of an example of a table of structured data including links to unstructured data. Fig.12 is an example of a table including links to unstructured data displayed in step d8. Fig.12In the table, a hyperlink pointing to the unstructured data corresponding to each data is embedded in the "hyperlink" column, and the user can select the link pointing to the unstructured data by clicking the hyperlink in the table.

[0098] Fig.13 is a diagram of an example of a table of structured data including links to unstructured data. Fig.13 is an example of a table including links to unstructured data displayed in step d8. Fig.13 As can be seen from FIG. 1 , although four points are specified as the graph extraction range based on characteristic B and characteristic E, seven items of structured data of materials 1 to 7 having different other characteristic values ​​are obtained.

[0099] In step d10, the unstructured data processing unit 30 of the information search device 10 acquires the unstructured data associated with the link selected in step d9 from the all-data storage unit 44. The unstructured data processing unit 30 sends the acquired unstructured data to the information display unit 50.

[0100] In step d11, the information display unit 50 of the user terminal 12 displays the unstructured data acquired in step d10 by the unstructured data processing unit 30. In this way, the user can effectively use graphs and experimental information that are not included in the structured data.

[0101] Figure 5 This is an example of a flowchart for explaining a process of creating structured data to be searched by the information search device of the present invention.

[0102] In step S1, the data extraction unit 42 of the information retrieval device 10 extracts unstructured data as structured data candidates from the unstructured data stored in the entire data storage unit 44. There is no particular limitation on the method for determining structured data candidates. In determining structured data candidates, the data of the target part can be determined by using a title represented by symbols such as braces or brackets, or by using a specific file format composed of a file format such as Excel (registered trademark).

[0103] In step S2, the data conversion unit 40 of the information search device 10 converts the structured data candidates extracted by the data extraction unit 42 in step S1 into structured data. The method of converting into structured data is not particularly limited.

[0104] In step S3 , the data conversion section 40 stores the structured data created in step S2 in the structured data storage section 38 .

[0105] The structured data creation process in steps S1 to S3 may be performed sequentially. Alternatively, the structured data creation process may be triggered by a user operation such as pressing a “structured data creation” button displayed on an interface screen displayed on the user terminal 12 .

[0106] As described above, the information processing system according to the present embodiment can provide an information search device, method, and program that enable a user to obtain unstructured data that is data to be effectively utilized.

[0107] Although the embodiments have been described above, it will be understood that various changes in form and detail may be made without departing from the spirit and scope of the claims.
