Construction of post-coordinated expressions allows users to specify new meaning by referencing existing SNOMED CT concepts. The use of post-coordinated expressions in information systems requires special software, a reasoner, to give the exact relations between post-coordinated expressions and existing SNOMED CT content. Thus, the performance characteristics of reasoners are important for implementation of post-coordination in information systems. This study aims to test how reasoners perform when a large number of post-coordinated expressions are added to SNOMED CT. The time needed to classify an ontology consisting of SNOMED CT plus an increasing number of post-coordinated expressions is measured. The best performing reasoner in this test classifies SNOMED CT plus 1 million post-coordinated expressions in 42 seconds. The time to classify grows a little less than quadratic as the size of the ontology increases. In conclusion, classification time is not a problem using current reasoners and current SNOMED CT releases even if a large number of post-coordinated expressions are added.<\/jats:p>","DOI":"10.3233\/978-1-61499-432-9-1048","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:26:30Z","timestamp":1740151590000},"source":"Crossref","is-referenced-by-count":0,"title":["Does SNOMED CT post-coordination scale?"],"prefix":"10.3233","author":[{"family":"Karlsson Daniel","sequence":"additional","affiliation":[]},{"family":"Nystr&ouml;m Mikael","sequence":"additional","affiliation":[]},{"family":"Cornet Ronald","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","e-Health &amp;ndash; For Continuity of Care"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T15:46:37Z","timestamp":1740152797000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=205&spage=1048"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-432-9-1048","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2014]]}}}
