Abstract

The invention discloses an entity combination-based mathematical natural language processing realization method and system. The method comprises the steps of establishing a mathematical entity extraction model used for extracting basic mathematical elements which constitute the mathematical entity, packaging the basic mathematical elements into the mathematical entity, performing permutation and combination on the mathematical entity, performing traversal of the mathematical relation table in one time in all combined types in the permutation and combination, and judging whether a relation can be combined or not according to the mathematical relation table so as to obtain a candidate relation set of correct recognition relations to complete processing. By virtue of the method, the mathematical entity can be mined from the mathematical problem text to combine and understand into a mathematical relation, so as to realize understanding of the mathematical problem text.

Description

technical field [0001] The present invention relates to natural language processing, in particular to a method and system for realizing mathematical natural language processing based on entity combination. The processing process is based on understanding relationships in natural language descriptions of elementary mathematics topics, and the processing results are used as the key to realizing mathematical knowledge reasoning and problem solving Operating procedures. Background technique [0002] Natural language processing (NLP) is based on the model of language ability and language application, and realizes the corresponding language model by establishing a computer framework, and continuously improves the language model. Natural language processing includes Chinese automatic word segmentation, part-of-speech tagging, syntactic analysis, natural language generation, text classification, information retrieval, information extraction, text proofreading, automatic summarizatio...
