Measures of semantic similarity and relatedness in the biomedical domain
Measures of semantic similarity between concepts are widely used in Natural Language Processing. In this article, we show how six existing domain-independent measures can be adapted to the biomedical domain. These measures were originally based on WordNet, an English lexical database of concepts and relations. In this research, we adapt these measures to the SNOMED-CT ontology of medical concep...
متن کاملMeasures of Semantic Similarity and Relatedness in the Medical Domain
In this paper we introduce a measure of semantic relatedness based on context vectors derived from medical corpora. We also extend a number of measures of semantic similarity for general English to the medical domain. We evaluate these methods with a newly created test bed of 30 medical concept pairs that were scored by three physicians and nine medical index experts. We find that our context v...
متن کاملThe semantic measures library and toolkit: fast computation of semantic similarity and relatedness using biomedical ontologies
UNLABELLED The semantic measures library and toolkit are robust open-source and easy to use software solutions dedicated to semantic measures. They can be used for large-scale computations and analyses of semantic similarities between terms/concepts defined in terminologies and ontologies. The comparison of entities (e.g. genes) annotated by concepts is also supported. A large collection of mea...
متن کاملEvaluating measures of semantic similarity and relatedness to disambiguate terms in biomedical text
INTRODUCTION In this article, we evaluate a knowledge-based word sense disambiguation method that determines the intended concept associated with an ambiguous word in biomedical text using semantic similarity and relatedness measures. These measures quantify the degree of similarity or relatedness between concepts in the Unified Medical Language System (UMLS). The objective of this work is to d...
متن کاملEvaluating Semantic Relatedness and Similarity Measures with Standardized MedDRA Queries
A potential use of automated concept similarity and relatedness measures is to improve automatic detection of clinical text that relates to a condition indicative of an adverse drug reaction. This is also one of the purposes of the Medical Dictionary for Regulatory Activities (MedDRA) Standardized Queries (SMQ). An expert panel evaluates SMQs for their ability to detect a condition of interest ...
