A multilingual medical thesaurus browser for patients and medical content managers.

This paper introduces a user-friendly browser interface which integrates multilingual search and browsing functionalities within medical thesauri via the internet. The tool is being developed as part of the GIN Austria Patient Information System and is based on an adapted datamodel of the MeSH thesaurus. A prototype offers the possibility to build up queries and export lists of MeSH main headings collected during browsing the relevant MeSH trees. The thesaurus browser can be used both by patients and citizens to build queries based on a controlled vocabulary to match them with existing documents within GIN and by medical information managers to find out appropriate keywords for interactive tagging or indexing of medical contents. A key component of this tool is the flexible choice of different languages of the MeSH datasource as well as of the user interface. Both can be changed independently at any point during a session. Another central aspect is the use of the UMLS Metathesaurus in combination with localized Thesaurus versions due to existing international character set problems.
