Description

Technical Field

[0001] The present application relates to the field of geographic information technology, and particularly to a geological data retrieval method, device, medium and product. Background Art

[0002] With the accumulation of geological work, a vast amount of geological data has been accumulated, forming a huge geological data database, which covers various forms of resultant geological data such as text, charts, audio and video, as well as physical geological data such as rock cores and specimens. The above geological data not only has extremely high value in the field of geological research, but also plays an important role in many fields such as mineral resource development, environmental monitoring, and urban planning, and is the resource basis, engineering basis and environmental basis. In recent years, the attention to geological work has gradually increased, and the demand for geological data has become increasingly strong. The continuous growth of the total amount of geological data provides a solid foundation for development, but also makes it gradually more difficult to accurately and quickly discover geological data.

[0003] The geological data accumulated over the years comes from various geological survey projects and engineering projects, covering all regions of the country, and the data has a large spatio-temporal span; the geological workers who carry out geological survey work and compile data come from different industries, and the data sources are diverse, covering many industries and fields; at the same time, with the continuous development of geological science, the description methods of the same geographical semantics have also changed over time, and there are also differences in the description methods of the same geographical semantics in different industries. This has led to unclear or missing descriptions of key spatial location information in the data catalogs of some precious historical data; there are multiple description methods for the same geographical semantics in a vast amount of data, or the geographical semantics corresponding to the same noun are different in different industries.

[0004] Regarding the spatial location information of geological data, although data compilers and users in each industry can use longitude and latitude for description, in different industries and research work, other description methods are also used. For example, when conducting geological surveys and geological scientific research, structures and tectonic belts are often used for description; when conducting mineral exploration work, mining area names are often used for description; when conducting hydrogeological, engineering geological and environmental geological surveys, industry-specific terms such as administrative regions, geographical coordinates, and natural geographical features are often used for description. Since it is not yet possible to associate these geographical semantics with the same spatial location information but with a large industry span, when querying and retrieving geological data at present, it is impossible to batch obtain geological data formed by each industry in the same region, and multiple rounds of retrieval are required to improve the integrity rate of the data.

[0005] The comprehensive retrieval of existing geological data mainly includes two categories: keyword retrieval and spatial location retrieval. Among them, keyword retrieval directly filters information such as the title of the data, file number, author, formation unit, mineral category, administrative division, start and end longitude and latitude coordinates, etc. by inputting the keyword information of geological data; spatial location retrieval directly obtains all geological data within the range by directly selecting the administrative region and longitude and latitude range of the data. Generally speaking, the deficiencies of the existing geological data retrieval methods are mainly reflected in the following aspects:

[0006] 1. It is difficult for keyword retrieval to retrieve all geological data generated by different working methods at one time;

[0007] 2. For geological data with missing geographical coordinates or implicit locations, it is impossible to discover the data by spatial location during retrieval.

[0008] Therefore, based on the above problems, there is an urgent need to provide an intelligent retrieval method for geological data to improve the retrieval efficiency and result reliability, and thus provide strong support for data retrieval in the geological and other fields.

[0055] Among them, the professional terms in different industries include: professional terms containing spatial location information in multiple industries such as geology, geography, engineering, hydrology, and environment.

[0056] S102, establishing a rich knowledge graph of geographical elements according to the professional terms in different industries and the corresponding spatial location information;

[0057] S102 specifically includes:

[0058] Preprocessing the professional terms in different industries and the corresponding spatial location information to obtain knowledge graph triples; the preprocessing includes: cleaning and deduplication, word segmentation and part-of-speech tagging, standardization, and triple format conversion according to a predefined mapping rule table; in the knowledge graph triples, the geographical location proper nouns in each industry are set as the ontology, and the remaining relevant spatial location information is set as attributes according to categories; the knowledge graph triples establish the relationship between various geographical semantics and spatial location coordinates.

[0059] Storing the knowledge graph triples for knowledge storage and performing dual management to establish a rich knowledge graph of geographical elements. Among them, dual management means that the knowledge graph triples simultaneously include professional terms in the geological industry and the spatial location information corresponding to the terms, and the rich knowledge graph of geographical elements can be managed separately with professional terms and spatial location information as the outlines.

[0060] S103, obtaining geological data; and extracting geographical element information from the geological data; the geographical element information is element information containing spatial location information;

[0061] S103 obtains the case-level and document-level directory information in the geological data;

[0062] S31. Extract the directory fields related to spatial location according to the file-level and document-level directory information and the geological data cataloging specifications. The directory fields related to spatial location include: title, document name, scale, administrative division, and content summary.

[0063] The specific extraction method is to efficiently extract the geographical element information involved in geological data based on natural language processing calculations.

[0064] S32. According to the directory fields related to spatial location, based on the geological work professional code set and the thesaurus, extract the spatial location information and geographical location specific nouns respectively. The geographical location specific nouns include: geographical names, mining area names, large tectonic belt names, and geological map sheet numbers. The geological work professional code set and thesaurus incorporate common geographical location specific nouns, professional terms, abbreviations, common names, etc. in the geological data related industries.

[0065] S33. Integrate the spatial location information, geographical location specific nouns, and the spatially formatted location information in the directory fields.

[0073] Specifically, for different types of retrieval information, list the geological data catalogs in different formats and display the multiple categories of spatial elements of the geological data to achieve intelligent retrieval of geological data with two-way deduction of geographical elements - spatial location information based on spatial relationships.
