Patent information analysis method and device

Abstract

The invention provides a patent information analysis method and device, wherein the method comprises the steps of: selecting analyzed patent information from a database to serve as basic data, and acquiring HTML (Hypertext Markup Language)-format webpages of the patent information from a website; specific to each data item in the basic data, respectively acquiring character strings capable of uniquely locating all the data items from the acquired HTML-format webpages, and respectively formatting the character strings into regular expressions for analyzing all data items; and analyzing the patent information from the unanalyzed HTML-format webpage of the website by using the regular expressions for analyzing all the data items, and saving the patent information obtained through analysis into the database. The method and the device disclosed by the invention can be used for adaptively establishing an analysis rule of the patent information so as to ensure that the analysis rule of the patent information can be updated automatically even though the HTML formats of the webpages change, so that the patent information is analyzed correctly, manpower is saved and the efficiency is increased.

Description

【Technical field】 [0001] The invention relates to the field of computer information technology, in particular to a patent information analysis method and device. 【Background technique】 [0002] With the rapid development of Internet technology, the Internet has become the main means for people to obtain information, and so is patent information. Almost all patent information in the world is released through the Internet, making it easier for people to obtain patent information, thereby promoting technological innovation and development. Now more and more enterprise users search patent information on the Internet and parse it into accurate data and save it in the local database, thus forming their own patent information library for in-depth use. [0003] When analyzing patent data published in Hypertext Markup Language (HTML) format, the user usually analyzes the patent information in HTML format, writes regular expressions that can accurately locate each data item (such as ...

Problems solved by technology

[0004] Although this method of parsing patent information has high parsing efficiency, website owners on the Internet often adjust the HTML format to display different effects on the webpage. This adjustment will inevitably lead to invalidation of regular expression rules set by users, thus The data parsed by the above parsing method is wrong or cannot be parsed

Unless the user reanalyzes the HTML format, rewrites the regular expression rules that can accurately locate each data item, and updates it into the computer program, this obviously brings a huge workload to the user, wastes manpower, and is inefficient
