[0004] There are also many programs that combine linguistic theories, grammatical information, etc. for data annotation and knowledge base construction. Knowledge bases that are biased towards linguistics, such as CLKB dictionaries (words, terms, synonyms, etc.), grammatical information, and corpus comprehensive language knowledge library, etc., but this kind of knowledge base only marks part of speech, grammar, etc., and the semantic information of vocabulary is less

example 1

[0048] Example 1: Angina pectoris is the most common clinical type of coronary heart disease, and it is a clinical syndrome caused by coronary insufficiency, sudden and temporary myocardial ischemia and hypoxia. The main manifestation is retrosternal or precordial pain, which often radiates to the inner side of the left arm, throat, and neck, as well as chest tightness, shortness of breath, and sweating. At present, angina pectoris of coronary heart disease is divided into two categories: stable angina and unstable angina. The prognosis of most patients with chronic stable angina is relatively good. Studies have shown that the average annual mortality rate is 2% to 3%, and the annual incidence of non-fatal myocardial infarction is 2% to 3%. The prognosis of unstable angina is relatively poor. This disease belongs to the category of "chest obstruction and heart pain" in traditional Chinese medicine. ——Source: Chinese Association of Traditional Chinese Medicine Diagnosis and T...

Abstract

The invention discloses a human-centered basic knowledge system construction method. The method comprises the following steps: constructing a semantic knowledge framework; selecting corresponding vocabulary entries from the existing vocabulary or dictionary; semantic system labels of the entries are determined and labeled; generating a semantic knowledge system taking the vocabulary entries, the vocabulary entry information and the semantic system labels as contents; the constructed semantic knowledge system is applied to text semantic annotation and serves natural language understanding and natural language processing of texts.

Description

technical field [0001] The invention relates to the technical fields of ontology construction and natural language processing, in particular to a human-centered basic knowledge system construction method. Background technique [0002] With the development of natural language processing and artificial intelligence technology, people are increasingly aware of the importance of semantic dictionaries, knowledge graphs, knowledge bases and knowledge ontology in natural language processing and natural language understanding. The knowledge base and ontology itself are not only the background context basis for machine understanding and analysis of natural language texts, but also the key to introducing semantic information into machine understanding and analysis and processing of natural language. [0003] The development of knowledge base, since it was put forward in the 20th century, the early WordNet (English), HowNet (Chinese) and some other knowledge bases or knowledge ontology...
