Problems solved by technology

However, this method does not add some word-forming rules of Chinese itself. It is still a probability method based on frequency, etc. When the accuracy rate reaches a certain level, it will be difficult to make a breakthrough, and the bottleneck is obvious.

Abstract

A method for automatically recognizing and manual assistance decimating scientific and technical terminology from Chinese patent documentations by a computer. According to the method, Chinese terminology which are possible to compose words are automatically recognized and decimated based on basic information of part-of-speech taggings by means based on rules on an point of view of Chinese phrase word-building, and the authenticity of the terminology is judged and determined based on manual assistance. The main steps include building various patent documentation bases based on fields; decimating repeat strings by using a special patent documentation base as a training corpus, syncopating and part-of-speech tagging repeat strings by using basic terminology, and checking repeatedly boundariesof repeat strings according Chinese accidence rules until the strings become receptible provision terminology. It is possible to affirm through manual assistance for further verifying the provision terminology.

Description

technical field [0001] The invention relates to a method for automatically identifying and extracting scientific and technological terms by using a computer, in particular to a method for automatically identifying and manually assisting the extraction of scientific and technological terms in Chinese patent documents by using a computer. Background technique [0002] With the development of information technology, people have more and more scientific documents, but manual processing has become impossible, so the introduction of automation technology is an inevitable trend. However, technical terminology is a major obstacle to the automatic summarization, automatic indexing, automatic classification and even machine translation of this information. It is a very urgent and meaningful task to automatically identify and extract scientific and technological terms in the literature [0003] Chinese patent application 03148989.3 discloses a method for automatically extracting multi...
