Problems solved by technology

However, the current methods only consider the semantic correlation of concepts in queries and documents, and do not consider the semantic correlation that also exists in the relationship between these concepts, which is very important for understanding the user's query purpose and It is very helpful to accurately match the target document
[0005] Therefore, various document sorting methods in the prior art often cause users to be unable to obtain desired query results quickly and accurately.

Embodiment Construction

[0019] The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in a flowchart or block diagram may represent a module, program segment, or portion of code that contains one or more logic devices for implementing the specified Executable instructions for a function. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. It should also be noted that each block of the block diagrams and / or flowchart illustrations, and combinations of blocks in the block diagrams and / or flowchart illu...

Abstract

The invention discloses a method and equipment for sorting a document. The method comprises the following steps of: according to user query and an ontology base, extracting queried semantic information; according to the document, the query and the ontology base, extracting document semantic information; determining a relational semantic relevance between the document semantic information and the queried semantic information; and sorting the document on the basis of the relational semantic relevance. According to the method and the equipment provided by the invention, the document sorting accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the field of information retrieval, in particular to a method and device for sorting documents. Background technique [0002] With the wide application and expansion of electronic information, a large amount of diverse information is gathered in various distributed systems. How to help users find useful information from massive information is a problem that has received more and more attention. [0003] Information retrieval technology is to search for information from a collection of documents, which may include: searching for a part of information in a document, searching for a document itself, searching for metadata describing a document, searching within a database, and so on. The information to be searched may also be diverse, such as text, sound, data, and so on. [0004] At present, document ranking is mainly divided into query-related methods and query-independent methods. The query correlation method refers to sorti...
