Multiple Terminologies in a Health Portal: Automatic Indexing and Information Retrieval

Factors affecting the effectiveness of biomedical document indexing and retrieval based on terminologies

“…For the first contribution, to the best of our knowledge, there are two main categories of works in the biomedical domain dealing with multiple terminologies: the one focuses on the use of multiple terminologies only for indexing biomedical documents [10,11], while the other only focuses on expanding the user query via a process of termino-ontological query expansion [49,6,38]. However, there is so far no work investigating the evaluation of the multi-terminology document indexing for biomedical information retrieval.…”

“…In their approach, each sentence in the document is represented as multiple bags of words independently of the word order correlation between words in the sentence and the ones in concept names. Similarly, authors in [11] presented a multi-terminology approach to indexing documents in the CISMeF portal but the concept extraction between free text and terminologies is based on the simple bag-of-words representation. Indeed, in their concept extraction method, the "bag of words" representing each candidate term is matched independently of the word order against all the MeSH, ICD10, SNOMED, CCAM and TUV terms that have been processed in the same way.…”

“…The indexing task can be based on one terminology (mono-terminology indexing) or several terminologies (multi-terminology indexing). While the former is usually based on MeSH, the latter is based on different terminologies (e.g., ICD-10, SNOMED-CT, GO [8,6,9], CCAM, TUV [10,11]). In general, indexing can be done manually or automatically.…”

“…The first one aims at building (semi)-automatic mappings between terminologies [15,16]. The second one, most related to our work, attempts to extract concepts from different terminologies in order to better cover the subject matter(s) of the document and so to improve the recall of concept extraction [17,10,11,9].…”

Aligning Biomedical Terminologies in French: Towards Semantic Interoperability in Medical Applications

“…The HMTP is a "Terminological Portal" connected to generic model database to search terms among all the health terminologies available in French (or in English and translated into French) and to search it dynamically. The ultimate goal is to use this search via the HMTP in order to: (i) manually or automatically index resources in the CISMeF catalog; (ii) allow multi-terminology information retrieval (Darmoni et al, 2009b;Soualmia et al, 2011).…”
