Building method for semantic knowledge base based on a dictionary

Abstract

The invention discloses a building method for a semantic knowledge base based on a dictionary. The method comprises the following steps that a knowledge database based on a dictionary semantic knowledge expression model is built; semantic knowledge paraphrased by semantic items are extracted according to a semantic knowledge extraction rule; the semantic item mapping for extracting the semantic knowledge is realized; the rest semantic knowledge paraphrased by the semantic items are extracted. The method provided by the invention can be used for flexibly and fast building the knowledge base containing rich semantics from the dictionary, and in addition, the knowledge expressed in the knowledge base has universality and authority. The invention simultaneously provides a deep semantic knowledge expression method and semantic similarity calculation method for semantic information processing of natural languages, wide application values are realized in the natural language processing field such as the information retrieval field, and the retrieval based on the semantics instead of keywords can be realized, so that the deep semantic retrieval result closer to the requirements of the user can be obtained.

Description

technical field [0001] The invention belongs to the technical field of computer semantic information processing, and more specifically relates to a method for constructing a dictionary-based semantic knowledge base. Background technique [0002] With the rapid development of computer technology, human beings have entered the era of information explosion. Massive digital information is generated, stored, disseminated and converted every day. While people obtain information more conveniently and quickly, they are also overwhelmed by the vast amount of information , which makes human beings have an increasing demand for computer cognitive ability, and a stronger desire for computers to understand natural language. The natural language understanding research born from the marriage of computer and linguistics has further expanded the field of vision of human language research. At the same time, the advent of the information age calls for language research to turn to the technical...

Problems solved by technology

[0009] In view of this, one of the main purposes of the present invention is to solve the problems of long construction period, high cost and insufficient expression of semantic knowledge in the existing semantic knowledge base. The paraphrase mode is used to realize the knowledge acquisition method, so that users can build a knowledge base with rich semantics from the dictionary flexibly and quickly
