Multi-dimensional information retrieval method

Abstract

The invention relates to a multi-dimensional information retrieval method. The method is realized through a multi-dimensional information retrieval system. The system comprises a client and a search engine, wherein the search engine comprises a task analysis engine and an index matching engine; the client comprises a task monitor, a user task analysis module and a user interface module; the task analysis engine comprises a genre database, a user task genre analyzer and a user task log database. By acquiring event information and user query historical information in various task processes finished by a user on a desktop, the user query intention is acquired, and user query genre expression is established, so that the user query precision is obviously improved, the user can quickly obtain a query result, the screening of unrelated query information is saved, the information retrieval time of the user is saved, the efficiency is improved and the user query experience is improved.

Description

Technical field [0001] The invention belongs to the field of computer information retrieval, and specifically relates to an information retrieval method, in particular to a multi-dimensional information retrieval method. Background technique [0002] Since the 20th century, the amount of information created by mankind has grown rapidly. It is estimated that since the 1970s, more than 500,000 books, more than 100,000 periodicals, about 500,000 patents, about 900,000 scientific reports, more than 100,000 conference documents, and more than 500,000 product samples have been published worldwide since the 1970s. The total number of scientific and technological papers published is nearly 5 million, and the number is growing exponentially. How to find the required information from this vast sea of ​​information has become an important task of information retrieval. As context-aware computing (Context-Aware Computing) has received more and more attention, context-aware information retr...
