Abstract

The invention relates to the field of computer processing of natural languages, and provides a special term extraction method. Firstly, patent literatures are categorized into literature libraries of various fields in accordance with the field which the literatures belong to; And secondly, the patent literature libraries of various fields are combined into a corpus, and special terms can be extracted from the corpus in accordance with the properties of the terms. The invention also provides a special term extraction system. The method and the system of the invention can not only improve extraction results of special terms, but apply the improved rules and possibilities into next extraction, which will increase the accuracy.

Description

technical field [0001] The invention relates to the field of natural language computer processing, in particular to a method and system for extracting technical terms in the document analysis process. Background technique [0002] The "Intellectual Property Course" compiled by the World Intellectual Property Organization in 1988 expounded the concept of modern patent documents: "Patent documents include research, design, development and patents that have been applied for or recognized as discoveries, inventions, utility models and industrial designs. A general term for published or unpublished documents (or abstracts thereof) related to the results of experiments, as well as to protect the rights of inventors, patent owners, and holders of industrial design and utility model registration certificates. It is further pointed out: "According to the general understanding, patent documents mainly refer to official publications of patent offices of various countries." For example:...
