Abstract

The invention discloses an accurate and rapid automatic indexing method of patent documents, comprising the following steps: establishing a classification word list of technical classification and keywords, wherein the classification word list is related to a preset technical subject, determining an applicant sorted list related to the technical subject according to the degree of significance, retrieving in the database of patent documents in all countries according to the technical subject to form a thematic database related to the technical subject, screening in the thematic database according to the applicant sorted list to screen out the patent data of a plurality of preset applicants, and correspondingly indexing the screened patent data in terms of the technical classification and the keywords according to the determined indexing mode, indexing proportion and the classification word list. The invention improves the accuracy of the patent indexing and the reading speed and indexing speed of the patent documents, and has obvious beneficial effect when the quantity of the patent documents is larger.

Description

technical field [0001] The invention relates to a data indexing method, in particular to an accurate and rapid automatic indexing method for patent documents. Background technique [0002] Retrieval and indexing of patent documents is an important task for most technology companies. Using the patent document search windows and platforms provided by the patent offices of various countries or various intellectual property organizations, you can easily search for the required patent documents. At the same time, reading, processing and indexing these patent documents, on the one hand, is convenient for technical personnel to search and use, and on the other hand, it is also an important basis for various tasks such as patent analysis. [0003] However, due to the huge number of patent documents, there may be thousands or even tens of thousands of related technology patents under a technical topic. If a technology strategy analysis is performed on an industry or a technical fiel...
