Construction of a Condensed Thesaurus for Building Radiology Ontology
نویسندگان
چکیده
The building of thesauri for large domains, especially for medicine, is a costly affair. However, in many domains thesauri can be constructed on an ontological basis [Wielinga , Schreiber, 2001]. We are developing an ontological information retrieval system for the retrieving of medical records from an electronic medical record system (EMR). We decided to use the UMLS as a basis for building this system, but its many synonyms and complex relationships unnecessarily complicate the retrieval process. In this paper, we present a method of constructing a condensed thesaurus, which contains terms practically used in medical records. It is hoped that this condensed thesaurus will effectively support the document indexing and retrieval processes.

متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...

متن کاملOntologies, Taxonomies, Thesauri: Learning from Texts
The use of ontologies as representations of knowledge is widespread but their construction, until recently, has been entirely manual. We argue in this paper for the use of text corpora and automated natural language processing methods for the construction of ontologies. We delineate the challenges and present criteria for the selection of appropriate methods. We distinguish three major steps in...
