Embodiment Construction
[0064] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0065] As mentioned in the background technology, at present, there are few research results on literature-oriented geographic knowledge extraction, and the extraction methods are usually based on knowledge base combined with machine learning and pattern matching. However, this method needs to rely on a large amount of manually labeled corpus, resulting in low utilization of the knowledge base, and the extraction process can only pe...

The invention discloses a method, device, storage medium and computer equipment for extracting geographic information knowledge points, and relates to the technical field of knowledge maps. Knowledge map reasoning performs deep semantic analysis to mine hidden knowledge points and improve the accuracy of geographic information knowledge point extraction. The method includes: receiving a knowledge point extraction request, the request carrying corpus information to be extracted; using a preset entity recognition algorithm to perform entity recognition on the corpus information to obtain a knowledge entity; The knowledge point is extracted from the corpus information to obtain the knowledge point; and the knowledge point extraction request is responded to by using the knowledge entity and the knowledge point. The invention is applicable to the extraction of geographic information knowledge points.
Description
technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a method, device, storage medium and computer equipment for extracting geographical information knowledge points. Background technique [0002] In the context of geographic information big data and the transformation and upgrading of surveying and mapping technology, there is an urgent need for geographic information knowledge services. However, because the knowledge contained in the document carrier cannot be used by automated systems, it cannot be processed by people in a convenient way. Management makes us face the situation of "massive data, information explosion, and hard to find knowledge". Knowledge extraction technology, that is, extracting knowledge from data of different sources and different structures, forming structured knowledge data, and storing it in the knowledge base can provide a strong data foundation for the development of geographic science ...
