Description

Technical Field

[0001] The present invention relates to the field of linguistics, in particular to the field of geographical linguistics, and more particularly to a geographical language system integrating multivariate data. Background Art

[0002] Geographical linguistics is an important discipline that studies the geographical distribution and differences of languages ​​from a geographical perspective. It has important application value in the fields of dialect research, language planning, and language resource protection. The common research method of geographical linguistics is to select a small number of survey items, conduct language surveys in multiple locations, and use language maps to present the geographical distribution of language phenomena, and then explain the reasons for these distributions in combination with social and cultural factors.

[0003] With the continuous development of information technology such as computers and the Internet, many more efficient and convenient research methods have emerged for geographical linguistics. Among them, the existing technologies related to geographical linguistics research methods are mainly divided into the following three categories:

[0004] The first category is the language field survey system. This method mainly designs various survey systems to manually collect and process language data, and then classifies and organizes them according to geographical location. This method mainly uses the survey system to collect language data, and does not involve data display functions. In addition, the association between language data and geographical location is manually operated, and there is a lack of relevant attribute analysis of survey points and survey objects.

[0005] The second type is to use GIS technology to create language maps. This type of method is mainly based on GIS technology, which draws and displays the collected language data on the map to realize the digitization of the language map. However, most language maps are made by combining language data with geographic information (i.e., the longitude and latitude of the distribution) on professional GIS software, which has high technical requirements for researchers and is often drawn according to the purpose of research. For researchers in related fields, the secondary use of data is relatively small, and the language map can only be further interpreted through secondary creation on public maps.

[0006] The third type is to use WebGIS technology to display language resources. This method collects language data submitted by the public through public platforms, or collects language data based on public databases, and displays the data on maps. There is no organic combination of language resource survey and language map display, and language collection still requires huge manual investment.

[0007] In general, among the various technologies involved in the current geolinguistic research, there is no technical solution that can achieve the integration of "language survey" and "result display". Most of them use a single language survey program to obtain data. These data need to be integrated and then use professional geographic information systems (GIS software) to make language maps. The survey efficiency is low, the cost is high, and it consumes more manpower and material resources. At the same time, language maps are often published in the form of papers with research content. The data obtained from language surveys cannot be directly re-created, and the data availability is low. In the existing technology, there is little analysis of the relevant attributes of geographical language and survey points and survey objects. The focus is on combining geographical distribution with language form for research. In fact, there are many factors that affect language variation, such as topography, socio-economic environment, cultural background, etc. The existing technology does not fully combine multiple factors for research. In addition, the data sources in the existing public language display platforms are relatively single, mainly manually input by investigators, or publicly collected language data and submitted by the public. This approach cannot screen suitable survey objects and let them submit data according to regulations. Therefore, a more flexible and convenient geographical linguistics research program is needed to meet the application needs in the fields of dialect research, language planning, and language resource protection.

[0008] It should be noted that this background technology is only used to introduce the relevant information of the present invention to help understand the technical solution of the present invention, but it does not mean that the relevant information is necessarily the prior art.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] As mentioned in the background technology, there are many problems with the existing geographical linguistics research technology. Therefore, a more flexible technical solution is needed that can integrate "language survey" and "results display".

[0030] In order to facilitate the understanding of the present invention, the current state of the art in geolinguistics research is first introduced starting from several typical existing technical solutions.

[0031] First, let me introduce the field survey system. The field survey system is mainly used for corpus collection. The existing corpus collection method is mainly through the development of computer software (such as the "Feifeng" field survey system). However, this method still needs to be manually merged into the database after the collection is completed, and the address on the computer can only be filled in manually and cannot be automatically located. If you want to conduct geographical linguistics research, you need to convert it into geographical coordinates. The "Feifeng" field survey system includes a language point management module and a recording and recording module. Among them, the language point management module is used for language point information recording, corpus importing, language point data management, and multi-corpus comparison. The recording and recording module is used for recording parameter settings. Through the combination of multiple survey and sorting functions, compared with general field survey programs, the "Feifeng" system has added functions such as monitoring recording quality and automatically correcting irregular recording materials. It is a field survey system that integrates recording, recording, sound proofreading, and multi-point comparison. However, the Feifeng system still manages survey points in the form of geographic information records. The system is Windows-based and cannot achieve automatic positioning. It can only select provincial, municipal and county units, and then the investigators fill in the town and village units. This recording method needs to be converted into longitude and latitude before the language map can be drawn in the GIS software. At the same time, due to the inconsistency of the coordinate systems used by different map service providers, the coordinate results obtained by querying the same administrative unit will be offset, resulting in differences in language maps. In addition, the Feifeng system only collects language resources and does not involve data display functions.

[0032] Secondly, the use of GIS technology to make language maps is introduced. The drawing of language maps is an important part of geographical linguistics. The use of GIS technology to make maps has realized the digitization of language maps. At the same time, GIS can better interpret the distribution characteristics and variation characteristics of languages, and explain the causes and processes of language variation. However, most of the language maps displayed are made by combining language resources with geographic information (i.e., the longitude and latitude of distribution) on professional GIS software, which has high technical requirements for researchers. They are often drawn according to the purpose of research and then published in the form of papers in combination with the research content. For public users, they cannot search for corresponding content according to their own interests; for researchers in related fields, the secondary use of data is relatively small, and they can only further explain the language map through secondary creation on public maps.

[0033] Finally, let's introduce the use of WebGIS technology to display language resources. There are two typical solutions, one is the language protection project collection and display platform, and the other is the Web dialect map based on Vue.js. Among them, the language protection project collection and display platform is an important part of the Chinese language resource protection project, a large-scale language and cultural project officially launched by the Ministry of Education and the National Language Commission in 2015. The platform uses the interface of the GIS system and adopts automated data statistics and analysis algorithms to generate a visual and accurate language data distribution map based on the user's search conditions and custom settings. Detailed information on specific items, including audio, can also be viewed. However, the data displayed by the platform has a strict collection process and data specifications. Investigators need to go to various places to collect original corpus data, and then professional technicians will classify and process the data, and finally upload it to the unified management system of Chinese language resources. The application data source of the Web dialect map based on Vue.js is mainly collected through statistical yearbooks, dialect databases, and Xiangyinyuan websites. That is, it is just a "display platform" for language resources, and does not involve the language field survey link. There is no collation and identification of linguistic knowledge, and the academic value is not high.

[0034] It can be seen that among the various technologies currently designed by the Institute of Geographical Linguistics, there is no technical solution that can achieve the integration of "language survey" and "result display". The data obtained by using a single language survey program needs to be integrated, and then a language map is produced using a professional geographic information system (GIS software). The survey efficiency is low and the cost is high. At the same time, language maps are often published in the form of papers together with the research content. The data obtained from the language survey cannot be directly reused, and most of them only reflect the geographical distribution of language phenomena, and are rarely combined with the relevant attributes of the survey points and survey objects for analysis. In addition, the data sources in the existing public language display platforms are relatively single, mainly manually input by investigators, or publicly collected language data and submitted by the public. This approach cannot screen suitable survey objects and let them submit data according to regulations.

[0035] In view of this, the present invention provides a new multi-data fusion geographic language system for geographic linguistics research, the purpose of which is to integrate multivariate data collection, integrate data collection and data display, and realize efficient data collection and automatic positioning matching as well as data query and secondary utilization. In summary, the scheme of the present invention integrates text, audio and spatial information in terms of data form; in terms of data content, it is based on the combination of language form and geographic space, supplemented by survey object information (including audio, age, gender, ethnicity, language environment of growth, etc.) and survey point attribute information (such as language affiliation, population composition, common cash crops, folk culture, etc.), to realize the linkage and combined display of various types of information. Among them, the multivariate survey data that the system of the present invention needs to collect and display is composed of survey content (including survey items and survey results), survey object information (including personal information and survey audio), and survey point information (including spatial information and attribute information). It also uses GIS technology in combination with information collection, Web, database and other technologies to build a multi-language resource database, develop an online survey system and a comprehensive geographic linguistics display platform for ordinary Internet users, and realize the integration of geographic linguistics language survey and data display, with a wider scope of application, without the need for professionals to perform additional data classification and sorting and map drawing.

[0036] It should be noted that, in the present invention, survey point refers to the research area, survey item refers to the vocabulary that can reflect the language characteristics of each survey point, multiple survey items constitute a survey vocabulary list, survey results refer to the language forms of these words at different survey points, and language maps are used to display the distribution of survey results in geographical space.

[0037] First pass Figure 1 and Figure 2 The system of the present invention is introduced from the perspective of logical architecture and module composition. Figure 1As shown, from the perspective of logical architecture, the system of the present invention adopts a three-layer architecture, including an application layer, a business logic layer, and a data layer; Figure 2 As shown, in terms of module composition, the system of the present invention includes an application terminal 201, a server 202, and a database 203. The application terminal 201 corresponds to the application layer, the server 202 corresponds to the business logic layer, and the database 203 corresponds to the data layer. The application terminal, the server, and the database system communicate through a network.

[0038] The application terminal 201 corresponding to the application layer is used to construct multivariate data survey content, obtain corresponding survey tasks from the server based on the survey content, and distribute survey tasks online to survey subjects for them to enter information to obtain survey data, locate the geographic location of the survey subjects, and upload survey data to the database in real time and display it in geographic language based on the data in the database. Among them, the application terminal 201 includes a management terminal 211, a mobile terminal 212, and a Web terminal 213. Figure 1 It can also be seen that the application layer includes a mobile terminal (for information collection), a management terminal 211 (for data management) and a Web terminal (for data display). The management terminal is responsible for exchanging data with the server and presenting the data to the user in various ways of expression. The Web terminal 213 provides users with services such as map browsing, data query, and data visualization. The mobile terminal 212 provides information entry services for the survey subjects. The management terminal 211 is connected to the data layer, including data entry and management of the data layer, and establishes logical associations between various data tables; the mobile terminal 212 is the main part of the online collection system, providing information entry services for the survey subjects, and supporting the input of text information, spatial information, and audio information; the Web terminal 213 provides users with services such as map browsing, data query, and data visualization.

[0039] The server 202 corresponding to the business logic layer is used to respond to the survey content of the application terminal in real time to obtain the corresponding survey task from the database and feed it back to the application terminal, and provide browser service and map service to the application terminal 201. It can also be simply understood that the server 202 receives and parses the request sent by the application terminal 201, sends a data request to the data layer, retrieves the corresponding data and returns it to the terminal. Among them, the server 202 includes a Web server and a GIS server. The Web server is used to receive requests from the application layer, send data requests to the data layer, and encapsulate the requested data into the data required by the application layer and push it. The GIS server is used to provide map services so that users can obtain map browsing services through the Web terminal.

[0040] The database 203 corresponding to the data layer is used to store survey data, store different survey data in different data tables according to their attributes, and generate survey tasks according to survey requirements. The data layer encapsulates the information with mutual logical relationships between various data tables according to the data request sent by the business logic layer. It is composed of a spatial database and an attribute database. The spatial database stores basic geographic data and spatial location information. The basic geographic data comes from online maps, and the spatial location information comes from online collected information. The attribute database is responsible for all data other than spatial geographic information, including survey content (survey items and survey results), survey object information (personal information and survey audio), survey point information (spatial information and attribute information) and other data. Among them, the spatial database is established based on ArcGIS SDE to store basic geographic data and spatial location information; the attribute database is established based on MySQL database to store all data other than spatial geographic information, including survey content (survey items and survey results), survey object information (personal information and survey audio), survey point information (spatial information and attribute information) and other data.

[0041] According to one embodiment of the present invention, in the system of the present invention, Figure 2 The mobile terminal 212 shown is set in the form of a WeChat applet, which can be configured on any mobile terminal, and the survey subjects can enter the data by themselves, without the need for special equipment or personnel to collect data. Investigators (researchers) can manage data through the background, coordinate language surveys and data display; survey subjects can enter corresponding survey information through the WeChat applet; ordinary users can access the language map through the browser, including map browsing, data query and thematic map visualization.

[0042] According to one embodiment of the present invention, Figure 3 As shown, the workflow of the system of the present invention is: the investigator publishes the survey task, uploads the survey vocabulary, and collects data; the survey subjects input text information and record audio data; the investigator supplements and processes the data and builds a multi-language resource library; the public users can visualize the survey data in the system through various keywords.

[0043] According to one embodiment of the present invention, Figure 4As shown, the system of the present invention uses the mobile terminal in the system to conduct an investigation, obtain the information of the survey object, the survey results and the spatial information of the survey point, and upload them to the database. Specifically, when researchers conduct field investigations, they can use information equipment (such as mobile communication equipment) to investigate multiple survey objects at the same time, and the survey objects enter the information by themselves to realize the online collection of multivariate data. Specifically, before the investigation, the investigators only need to upload the survey word list to the database through the management terminal, and the data layer will generate the corresponding survey task and the corresponding UID (User Identification). The UID is used as the credential for the survey object to enter the survey system, and is allocated by the investigator to avoid the entry of invalid data. The survey object enters the UID in the applet to obtain the survey task. After receiving the instruction, the server calls the function of obtaining the survey task, and the function returns the survey task for the survey object to fill in. In the process of the survey object entering information, the form data will be uploaded to the server in real time, and the filled form data can be restored and continued to be filled in when the survey object returns to the page. The mobile terminal is presented in the form of a small program, and the vocabulary is used as the survey content. The recordings of these vocabulary in different places can be obtained in large quantities and quickly. Compared with the field survey system in the prior art, it is not based on computer software as a carrier, nor does it require professionals to conduct field surveys on them. The data obtained by the survey is not stored in the computer terminal used for the survey, and there is no need to sort the data twice. The data obtained by the survey using the system of the present invention is transmitted to the database in real time. In addition, the field survey system using computer software as the presentation method in the prior art does not support direct acquisition of positioning, and can only fill in the provincial, municipal and county units. The specific town-level and village-level units can only be entered in the form of text. There may be adjacent villages with the same name, or different statements of the village name, which leads to inaccurate positioning obtained by searching on the map at the end. The present invention directly uses GIS server to provide accurate positioning, that is, the mobile terminal small program in the present invention can obtain spatial positioning information in real time, and use the small program to collect data, without carrying a computer for field survey, only a mobile device such as a mobile phone can be realized, no additional applications need to be downloaded, and information can be filled in by searching the small program in WeChat.

[0044] According to one embodiment of the present invention, the present invention Figure 4The step 302 shown designs the survey task as a "one word one recording" form. For example, if there are 10 words in the survey word list, 10 recording pages will be generated in the survey task; further, the present invention sets the survey task as an interruptible and restorable task. After the survey subject completes the survey task, he can flexibly complete the information entry according to his own time. The audio and text information entered each time will be retained on the local end and automatically uploaded to the database. The investigator can view the data uploaded by the survey subject at any time through the database, and correct and supervise the situation of incorrect information filling and failure to complete the task in time. The survey subject can continue to complete the survey task on the basis of the last entry at any time. Compared with the existing field survey workflow, the data collection process of the system of the present invention does not require the investigator and the survey subject to conduct one-to-one. Through the online system, one investigator can survey multiple survey subjects at the same time, that is, after mastering the operation process, the survey subject can record by himself, and even remote guidance survey can be realized. The content finally filled in by different survey locations and different survey subjects will be uploaded to the background database, and no integration is required, and the complete survey data can be viewed. It can be seen that the method of using the system of the present invention to conduct geographic language data survey is faster and more efficient.

[0045] According to one embodiment of the present invention, the system of the present invention utilizes Figure 4 The management terminal 211 shown enters data and performs operations such as classification, cleaning, and filtering on the data. There are two main aspects of data entry. One is to input the corresponding IPA text (International Phonetic Alphabet) according to the survey audio, and classify different language forms of the same vocabulary. The above IPA text and vocabulary types are the survey results that need to be displayed; the second is to search for data such as language classification, population composition, common cash crops, folk culture, etc. of the survey points through the websites of the provincial statistics bureaus, and perform operations such as classification, cleaning, and filtering on the data, cleaning data that does not conform to the facts, filtering duplicate data, and organizing the above data into Excel tables and uploading them to the database.

[0046] According to one embodiment of the present invention, in the system of the present invention, Figure 4The database 203 shown includes an attribute database established based on the MySQL database, and a spatial database established based on ArcGIS SDE. The attribute database mainly stores survey object information, survey point information and survey content, and the spatial database is used to store survey point spatial information and basic geographic data. Survey point spatial information is the specific location where the language feature survey occurs. The spatial distribution visualization service provided by the system of the present invention is displayed based on these specific points. The system of the present invention studies the mutual logical relationship between each information through the management terminal 211, realizes multi-table joint query, and constructs a language resource library of multivariate data. In the MySQL database, a survey point data table, a survey object data table and a survey content data table are established. Longitude and latitude are used as common primary keys in the survey point data table, the primary key of the survey object data table is the survey object ID, and the primary key of the survey content data table is the UID (User Identification) generated by the survey vocabulary. There is a one-to-many relationship between survey points and survey objects. The survey point data table and the survey object data table are associated through longitude and latitude to obtain the associated information of the survey point and the survey object. On this basis, the survey content data table is connected through UID to obtain the complete information of the survey point, survey object and survey content, so as to realize the association of multiple data tables and thus realize joint query, provide data operation interface for the application layer application, and return corresponding data according to the data request sent by the server. An association relationship is formed between each data table item in the database of the system of the present invention, so that a variety of data query services can be provided to the outside. For example, when querying the information of a certain survey point, the information of the survey object at that point and the survey content can be returned at the same time; or, when querying a certain survey word of the survey content, the information of all survey points with this word and the information of the survey object that completes this survey content can be returned.

[0047] According to one embodiment of the present invention, in the system of the present invention, an HTTP link is established between the application terminal and the server by creating a web page, and information is transmitted to the server to establish a connection request, a data source name and a requested data identifier. The server parses the application terminal request, retrieves the corresponding data based on the requested data identifier and returns it to the application terminal, thereby realizing the interaction of the geographic linguistics display platform.

[0048] According to one embodiment of the present invention, the GIS server in the system of the present invention adopts the JavaScript API (Baidu Map API for JavaScript) of Baidu Map Service, and by retaining the basic mouse scrolling zoom, panning, and specific level zooming operations of the map, based on the Baidu Map API development process, creates a main map container, instantiates and initializes the map, adds a map overlay according to the longitude and latitude coordinates, and adds interactive listening response events on the overlay points, thereby providing users with three functions of map browsing, data query, and map thematic expression on the Web side. By creating map browsing, data query, and map thematic modules on the web page, it is convenient for ordinary users to use. Among them, the map browsing module refers to the visualization of the geographical distribution of the survey point. Through the marking point coverage function of the Baidu Map API, according to the longitude and latitude coordinates of the survey point located by the online collection system, the same dialect points are marked with different colors according to the dialect classification of the language on the map, and the same color system can be used for the same language classification. The data query module refers to the query of attribute information and spatial point of survey results. Attribute information query is to query the distribution of survey points in a certain area under certain conditions through different screening conditions such as region, survey point attribute information, survey object information, etc.; spatial point query is to click on the point element of the survey point on the map, and the attribute information, survey content and survey audio of the survey point will pop up, and the audio data of the survey point can be played at the same time. The map thematic expression module is to view the geographical distribution of specific survey content, including survey results and survey audio. At the same time, it can combine the personal information of the survey object and the attribute information of the survey point to filter out the distribution of survey data under specific conditions, including the visualization of language form and vocabulary type, to view the impact of different factors on vocabulary variation. Among them, the visualization of vocabulary type can customize various types of expression symbols to achieve map thematic expression.

[0049] As mentioned in the background technology, there are two common ways to display survey data in the prior art. One is to use the acquired data to draw a language map on a professional mapping software (such as ArcGIS, QGIS and other geographic information systems). The drawing results are generally used as an illustration of a geographical linguistics research paper, or uploaded to a language map website. They are made according to the research purpose and content of the researchers, and there is no database to store this information; the second is to use the WebGIS system to realize the display of online maps. The existing online language maps require manual entry of data into the system and display of these data on the map. It does not involve the field survey stage, but only collects publicly available materials for display, which is not timely. In contrast, the system of the present invention uses the same database for display and collection. The collected data can be displayed through simple processing, without the need to use professional mapping software for drawing, and any user can view the survey data by entering the web page through a browser.

[0050] Based on the design of the database in the present invention, different data items are used to record different contents and associate them. In the system of the present invention, when data is displayed, the attributes of the survey object and the survey area can be integrated, that is, the survey results can be viewed from the social identity and social background of the survey object. General language map websites only support inquiries of survey area attributes, such as searching for the distribution of survey points of the same language family (such as Tibeto-Burman language family), that is, displaying all survey points belonging to the Tibeto-Burman language family. On this basis, the present invention integrates the attributes of the survey object, such as screening the survey points of "Chinese language points" and "the survey object is the Han nationality", which can be compared with the distribution of survey points of "Chinese language points" and "the survey object is other nationalities". Since the survey data of the present invention is collected by one word and one table, the statements of specific survey words at different survey points can also be viewed when querying data, such as the survey result of the word "corn" at the survey point of "Chinese language points" and "the survey object is the Han nationality" is "corn", and the survey result at the survey point of "Chinese language points" and "the survey object is other nationalities" is "corn", and "corn" may come from other national languages, thereby conducting a more in-depth study. Compared with existing solutions, the present invention supports customized data display, which allows other users (other language researchers) to search according to their own research interests and discover points worthy of further study.

[0051] According to one embodiment of the present invention, the present invention arranges that the online base map of the map also includes satellite images. Assuming that the distribution points of "corn" and "maize" in a certain area have an obvious pattern (for example, "corn" is concentrated on the left side of the area, and "maize" is concentrated on the right side of the area), and the satellite image shows that the boundary between the two is composed of mountains and rivers, the spread and evolution of the language can be further analyzed, which is information that the established language maps cannot provide.

[0052] The data investigation process and data interaction process of the system of the present invention are demonstrated in detail below with reference to the accompanying drawings.

[0053] like Figure 4 As shown in the figure, it shows the workflow of the mobile online survey applet, where the management end is operated by the investigators, and the mobile end is the WeChat applet, which is operated by the survey subjects. The specific steps are as follows:

[0054] S301, the investigator customizes the survey content, uploads the survey word list through the management terminal and issues the survey task to the survey object. The investigator can determine the survey word list according to his own research purpose and research content, and upload it to the MySQL database provided by this application. The survey word list consists of four parts: sequence number, vocabulary, notes and IPA, and the upload format is Excel table.

[0055] S302, after receiving the survey word list uploaded by the investigator, the data layer generates the survey task and the UID corresponding to the word list according to the preset format, binds the UID to the survey task, writes the word list content in the survey content data table, and uploads it to the server at the same time.

[0056] S303, the investigator determines the survey subject suitable for the task and assigns a UID, through which the survey subject accesses the WeChat mini program.

[0057] S304, after receiving the instruction, the server calls the function of obtaining the survey task according to the data identifier corresponding to the UID, and the function returns the survey task to the mobile terminal.

[0058] S305, the survey subject enters information in the mobile online survey system, including text information and audio data. The survey subject first enters personal information. After receiving the data, the data layer will create a data row in the survey subject data table. After completing the personal information entry, the system generates a recording interface. Each word corresponds to a recording interface for the survey subject to record one by one.

[0059] S306. After each recording, the recording data will be automatically uploaded to the server to ensure real-time updating and preservation of the data. The next time the survey subject enters the mini program, the system will automatically synchronize the entered data to the mobile terminal to facilitate subsequent operations.

[0060] S307, after receiving the data submitted by the user, the server stores it in the database, and the investigators can access and manage the data through the management terminal. When the mobile terminal enters data again, the system will re-upload the database and synchronously update the data in the database.

[0061] like Figure 5 As shown, it shows the data query and display process of the web page based on the system of the present invention, and the specific steps are as follows:

[0062] S401, select a region, that is, the user selects a region through a web page interface. According to an embodiment of the present invention, the system of the present invention provides two selection methods: administrative division and polygon selection.

[0063] S402, map marking points, the user zooms the map to the selected area in the web interface, and overlays marking points in the selected area, distinguishing different languages ​​by color, and the marking points show the survey points in the area.

[0064] S403, click on the information point, that is, the user clicks on the survey point mark on the map, and the system will pop up the basic information of the survey point, including the survey point name, administrative division, longitude and latitude, and language classification.

[0065] S404, expand the data panel. The user can expand the data panel by clicking on the data panel. The data panel will display various survey data corresponding to the selected area, including audio, text, survey subjects, etc.

[0066] S405, viewing survey data, the user can click the corresponding option to view the detailed information of the survey point corresponding to the selected area, obtain the survey content and survey object information of the survey point, and play the audio data of the survey point.

[0067] On the basis of map browsing, the system of the present invention also provides a data query function, which is realized by selecting a region and a map point and then executing the following steps:

[0068] S413, searching the survey point attribute information (such as survey point language family, language classification, etc.) or survey subject personal information (such as gender, ethnicity, etc.) in the search box, and comparing the same information in the survey point data table and the survey subject attribute table.

[0069] S414, displaying survey point elements that meet the search conditions. For example, after selecting "Yunnan Province", the distribution of survey points with survey data in Yunnan Province will be displayed. Assuming that the survey point language family is divided into Sino-Tibetan language family (Chinese, Tibetan) and Austroasiatic language family (Deang, Wa), at this time, select the survey point belonging to "Deang language", and only the distribution of Deang language in Yunnan Province will be displayed; if "Chinese" and "the survey object is Deang people" are selected, the distribution of Deang people who speak Chinese in Yunnan Province will be displayed.

[0070] On the basis of data query, the system of the present invention also provides a map thematic expression function, which is realized by selecting regions and map points and then executing the following steps:

[0071] S423, the user inputs a specific survey word, the same word information will be compared in the survey content data table, and the distribution of survey points containing this word in the survey word table will be displayed.

[0072] S424, the user clicks on each survey point to view the basic information of the survey point and the survey result of the word.

[0073] S425, customize the symbols of the vocabulary survey results, check the distribution of language features, and realize the thematic expression of the map. For example, after the user selects "Yunnan Province", the distribution of survey points with survey data in Yunnan Province will be displayed. Searching for the word "corn", it is found that the survey points in Yunnan Province are divided into three titles: "corn", "corn" and "corn". At this time, the symbols of different titles can be set, such as "corn" is red, "corn" is blue, and "corn" is green, so as to obtain the characteristic distribution of the word "corn" in Yunnan Province. On this basis, the user can further search for the attribute information of the survey point or the personal information of the survey object, and conduct a more detailed analysis, such as screening the distribution of the survey results of the word "corn" in the "Chinese" survey point.
