Method for automatically extracting terms from Chinese electronic document

Abstract

The invention relates to a method for automatically extracting terms from a Chinese electronic document. The method is characterized by comprising the following steps of: step S01: processing the electronic document into a group of word strings consisting of atomic words with a special property; step S02: counting the frequency of the atomic word strings and substrings, adopting the atomic word string with the appearance times being more than N times as a candidate term, wherein N is a settable parameter; and step S03: deleting the term which only appears as a substring in a candidate term set to obtain a term set appearing in the document, and realizing the purpose for automatically extracting the terms in the Chinese electronic document. The method has the effects and benefits that the real problem and difficulty that the performance for automatically extracting the term is not high and the automation degree is limited can be solved. The high-efficient automatic method for extracting the terms is a foundation for automatically processing a text and can powerfully guarantee the information search, text summarization, content management and the like. The good term extracting method can promote the automation degree and the performance of the work.

Description

technical field [0001] The invention belongs to the field of natural language processing, and relates to a method for automatically extracting word sets from Chinese electronic documents. Background technique [0002] In recent years, with the rapid development of scientific research, economics, Internet and other fields, the number of electronic documents has increased rapidly. How to process these massive electronic documents quickly and effectively has become one of the key tasks in the fields of information retrieval, knowledge management, and Web services. . As a result, automatic electronic document processing technologies such as text retrieval, classification, and automatic summarization have become research hotspots in related fields. Among these techniques, automatic extraction of all words in an electronic document (“prompt” for short) is a fundamental work. The word prompting method of the present invention is aimed at the automatic processing of Chinese electr...
