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 کاملWeb-Based Semantic Similarity: An Evaluation in the Biomedical Domain
Computation of semantic similarity between concepts is a very common problem in many language related tasks and knowledge domains. In the biomedical field, several approaches have been developed to deal with this issue by exploiting the structured knowledge available in domain ontologies (such as SNOMED-CT or MeSH) and specific, closed and reliable corpora (such as clinical data). However, in r...
متن کاملSemantic Similarity in Biomedical Ontologies
In recent years, ontologies have become a mainstream topic in biomedical research. When biological entities are described using a common schema, such as an ontology, they can be compared by means of their annotations. This type of comparison is called semantic similarity, since it assesses the degree of relatedness between two entities by the similarity in meaning of their annotations. The appl...
متن کاملResearch Paper: Semantic Classification of Biomedical Concepts Using Distributional Similarity
OBJECTIVE To develop an automated, high-throughput, and reproducible method for reclassifying and validating ontological concepts for natural language processing applications. DESIGN We developed a distributional similarity approach to classify the Unified Medical Language System (UMLS) concepts. Classification models were built for seven broad biomedically relevant semantic classes created b...
متن کاملA framework for unifying ontology-based semantic similarity measures: A study in the biomedical domain
Ontologies are widely adopted in the biomedical domain to characterize various resources (e.g. diseases, drugs, scientific publications) with non-ambiguous meanings. By exploiting the structured knowledge that ontologies provide, a plethora of ad hoc and domain-specific semantic similarity measures have been defined over the last years. Nevertheless, some critical questions remain: which measur...
