Document retrieval and analysis system

Abstract

The invention provides a document retrieval and analysis system, comprising a basic retrieval module, an expansion retrieval module, a multi-data source integrated retrieval module, a retrieval result processing module, a semantic database development module, a data mining and natural language processing module, a patent information intelligent analysis result visualization technology research module, and a user management module. The document retrieval and analysis system is based on data collection and processing, performs statistic and association analysis on patent data in terms of a plurality of patent description items like year, applicant, inventor, key words and so on, displays analysis results by combination with a visualization technology, and further discovers the relation of patents and information of patent inventors. Compared with the prior art, the document retrieval and analysis system has the advantages of being capable of retrieving patent information intelligently, performing statistic and association analysis on the patent data on the base of intelligent retrieval, and carrying out visual display of the analysis results by combination with the visualization technology.

Description

technical field [0001] The invention relates to the field of information retrieval, in particular to a document retrieval and analysis system. Background technique [0002] With the rapid development of information technology, electronic documents are replacing some traditional paper publications due to their advantages of various forms, large capacity, small size, easy information sharing and easy duplication. The accompanying electronic literature retrieval has become a more effective way to obtain information. [0003] The electronic literature retrieval methods that exist today are usually based on counting word frequency. This type of method is mechanically counted and matched, ignoring the actual semantic meaning of the word itself and the semantic relationship between words. Relevance, the retrieval effect is not ideal. [0004] At the same time, in order to avoid unnecessary patent disputes in the promotion and application of technology, each enterprise will carry ...

AI Technical Summary

Problems solved by technology

The number of patent documents related to an enterprise may be very large. At the same time, the analysis of patent documents needs to rely on the professional knowledge and work experience of personnel. The labor cost is high, which is relatively unfavorable for patent risk assessment.
