Problems solved by technology
However, the construction of geographic ontology and geographic knowledge base requires the participation of domain experts, and the consistency and integrity of the constructed geographic ontology and geographic knowledge base are maintained. Maintaining such a large geographic ontology and geographic knowledge base requires a lot of manpower. And it is impossible to update the data in time, especially when the affiliation relationship changes, it usually needs to modify more nodes, and it is not easy to achieve real-time performance

Embodiment Construction
[0069] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0070] Such as figure 1 As shown, a method for representing the integrity of geographic location entities based on the interactive question-and-answer community-Baidu Know includes the following steps:
[0071] Step 1): extract the defect geographic location entity through data processing; wherein, the defective geographic location entity is a geographic location entity with missing or fuzzy regions, which is recorded as defectLoc;
[0072] The present invention first utilizes the geographic location entity automatic recognition method proposed by Li×w to identify the geographic location entity, an...

The invention relates to a geographic location entity integrity expression method based on the interactive question and answer community-Baidu knows. The method includes the following steps of firstly, extracting the defect geographic location entity defectLoc through data processing; secondly, generating the problem 'which region does a certain defectLoc belong to' is generated for the extracted defectLoc, and conducting retrieval through Baidu knows; thirdly, extracting characteristics according to the retrieval result, calculating the score showing the regions which the defectLoc belongs to, and constructing the characteristic vector of the region which the defectLoc belongs to; fourthly, conducting integration on the defectLoc through rules. The method is based on the complaint texts of microblog cities, the geographic location entity integrity expression method based on Baidu knows is provided for solving the problem that because geographic location entity expression has the disadvantages of being irregular and unstructured, workers can hardly conduct statistical analysis, high accuracy for defect geographic location entity integration is achieved, and the requirements for actual application can be well met.
Description
technical field [0001] The invention belongs to the technical field of completeness expression of geographic location entities in microblog city complaint texts, and in particular relates to a method for complete expression of geographic location entities based on an interactive question-and-answer community-Baidu Know. Background technique [0002] In recent years, with the rise of microblogs asking about politics, more and more government departments have set up official microblogs to interact with ordinary people. For microblog city complaint information, due to the huge number of complaint microblogs received every day, geographical location entities sometimes lack regional information. A complete geographical location entity should include two parts of place name area and place name, for example, "R&F Festival Walk, Dougezhuang Township, Chaoyang District". However, the geographical location entity in the Weibo city complaint text has the following phenomena: 1. The pl...
