Five participants, including a content domain expert and a UMLS Expert, manually extracted and mapped terms to UMLS concepts for two disease summary documents from NLM&amp;apos;s consumer health site, Genetic Home Reference. The resulting adjudicated annotations were used as a gold standard. Differences&amp;apos; in automated term extraction and mapping between MMTx and MetaMap were noted. Afailure analysis was conducted to categorize the types of terms not correctly mapped by MMTx. The most frequent type of failure (30%) resulted from missing inferential or world knowledge. Characteristics of each category are discussed. We distinguish between classes of failures that may be easily rectified, such as alternative retrieval strategies to extract exact matches, and ones that require additional research, such as coordinating conjunctions, co-reference resolution, and word sense disambiguation.<\/jats:p>","DOI":"10.3233\/978-1-60750-949-3-763","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T17:07:49Z","timestamp":1740157669000},"source":"Crossref","is-referenced-by-count":0,"title":["Failure Analysis of MetaMap Transfer (MMTx)"],"prefix":"10.3233","author":[{"family":"Divita Guy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Tse Tony","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Roth Laura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2004"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T17:46:14Z","timestamp":1740159974000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=107&spage=763"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-949-3-763","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2004]]}}}
