Abstract

The invention provides a knowledge graph construction method and system. The method comprises the following steps: acquiring corpus information of at least one domain of a to-be-constructed knowledgegraph; carrying out word segmentation and part-of-speech tagging on knowledge text content fragments included in the corpus information to obtain the key words in the knowledge text content fragments;matching the key words with the domain ontology according to the preset rules to obtain the knowledge element instances in the knowledge text content fragments, the attributes of the knowledge element instances and the association relation between the knowledge element instances, wherein the domain ontology includes a domain topic, at least one model included in the domain topic, attributes of the model, and associations between the models, and the model includes at least one knowledge element instance; and constructing the knowledge graph according to the knowledge element instances in the plurality of knowledge text content fragments, the attributes of the knowledge element instances and the association relation between the knowledge element instances. The automatic construction of theknowledge graph is realized, the construction cost of the knowledge graph is reduced, and the construction efficiency and accuracy of the knowledge graph are improved.

Description

technical field [0001] The invention relates to the field of professional digital publishing, in particular to a method and system for constructing a knowledge map. Background technique [0002] Knowledge service has been a hot spot in the field of professional digital publishing recently, and the country's large investment in this area has also accelerated the time for knowledge service to be implemented in publishing units. However, the current domestic knowledge service system is generally still a traditional document-level knowledge service, providing traditional full-text search methods, and resource association is only a way of linking documents and references. [0003] In order to realize real knowledge retrieval, it is crucial to construct various types of knowledge systems as the basis for knowledge retrieval. At present, some leading professional publishing houses in the construction of knowledge systems have already accumulated a certain amount of thesaurus in the...
