Problems solved by technology

This algorithm relies on association rules to find cases, and needs to establish rules from previous cases, which is relatively complicated, and the accuracy of the rules is difficult to guarantee
And there is no better unified management case model, so it is difficult to directly match

Abstract

An ontology matching based case search system includes an entity attribute input group module, an input model management module, an ontology matching module, a WordNet term matching library module, a multi-data source module, a heterogeneous data management module, an output ontology set module, and a matching result display module; the ontology matching module can construct a node structure drawing by ontology examples of the heterogeneous data management module according to a built-in structure matching algorithm, calculates the total similarity among nodes through a structure relationship, is connected to the output ontology set module, and transmits the searched ontology examples. The search system inputs the whole case, searches similar cases, and can achieve multi-data source-oriented ontology matching-based case search.

Description

technical field [0001] The invention relates to a technology in the field of information processing, in particular to a case search system based on ontology matching. Background technique [0002] In the computer diagnosis and treatment management system, there is a large amount of patient file information, and case analysis of patient files is the basic requirement of this computer application field. Cases are used to describe a unique whole with a series of feature sets, and convey a variety of effective and targeted information. In this computer diagnosis and treatment management system, case search for related cases is of great significance. There have been many researches and applications on the associative search based on single text and one-dimensional elements, but the search based on the whole case has not yet mature application and technical support. [0003] Different from the traditional matching reasoning mode of rule-based reasoning, this is a new way of usin...
