Kin Wah Fung MD, MSc, MA The UMLS Team National Library of Medicine Workshop on the Future of the UMLS Semantic Network Annual reports and feedback from UMLS licensees
Background • One of the requirements of the UMLS license is to submit an annual report of UMLS usage within 30 days of the end of each year • Up to last year, a free-form email (with suggested section headings) was the main way to collect the annual reports. Disadvantages: • low response rate (usually less than 100 received each year) • difficult to analyze • From 2005, online form to collect annual reports. Advantages: • more structured questions • easier to analyze • targetted email reminders possible => higher response rate
Format of online annual report • Logon page – identity authenticated with UMLS license number • Main report page: • user info: affiliation, activity type, computing environment • usage of UMLS • feedback on user support and documentation • Optional sections for feedback on: • Metathesaurus • Semantic Network • Lexical tools • UMLS Knowledge Source Server
How long have you been using the UMLS? • Range 2 months – 15 years • Average: 4.3 years • Median 2.3 years • Significantly longer than the rest of respondents - average 2.6 years, median 1 year (Independent-samples T test, 2- tailed p = 0.003)
Usage of the Semantic Network • How have you used the Semantic Network? • in a research setting – 69 • in a production environment – 7 • Ways in which Semantic Network is used: • in natural language processing • word sense disambiguation • tagging of natural language expressions • natural language generation • ontological uses • finding concept distance • reference for building biomedical ontologies • other uses • suggesting relationships between UMLS concepts • restricting search of terms in the Metathesaurus • research on structure of Semantic Network
Components of Semantic Network used • Do you use the Semantic Network on its own or in conjunction with the Metathesaurus concepts? • on its own - 15 • in conjunction - 58
What improvements would you suggest? • more semantic types (4) • better description of semantic types and how they are assigned (2) • multiple hierarchies • more semantic relations • more uniform granularity • extension of relations to concept level • evolve towards a formal ontology
