Combining Term-based and Concept-based Representation for Clinical Retrieval
2017
Text Retrieval Conference
Preserved Fulltext
Different document representation methods, i.e., term based representation and concept based representation, have been proposed to solve this question. ...
The results show that these two representations perform differently on the scientific abstract and clinical trail data sets. ...
Existing studies solve the clinical related retrieval task in two directions based on how the documents and queries are represented, namely term based representation and concept based representation. ...

For this year, we used similar methods as we used in TREC PM17, i.e., term based representation and concept based representation. ...
In addition, we also tried to combine the different representation with results filtering and two-round retrieval. ...
Term base representation One intuitive method is to finish the retrieval task in term based representation with the different query fields merged as one combined query. ...

Moreover, when combining the relevance scores obtained from our technique and a term-based representation approach, the achieved performance is comparable to the best TREC 2011 systems. ...
However, it has been shown that these techniques are effective only when combined with a traditional term-based representation approach. ...

For the retrieval of relevant medical literature, we investigate methods that are capable of comparing the documents' semantic networks in terms of structure and semantics. ...
The goal of case-based retrieval is to assist physicians in the clinical decision making process, by finding relevant medical literature in large archives. ...
For instance, in [18] queries and documents are transformed from their term-based originals into medical concepts as defined by the SNOMED CT ontology 2 . ...
