BabelMeSH is a multilanguage search for MEDLINE/PubMed. We created a database of Arabic translations of MeSH terms and other medical terms using MySQL and developed a Web interface for searching MEDLINE/PubMed in Arabic. We evaluated the accuracy of BabelMeSH using a list of medical terms from BMJ Clinical Evidence. The accuracy was 58% (machine scoring) and 65% human review.) The result obtained may be explained by variations in expressing medical terms in Arabic.
