A Document Clustering and Ranking System for Exploring MEDLINE Citations
Design: A text mining system framework for automatic document clustering and ranking organized MEDLINE citations following simple PubMed queries. The system grouped the retrieved citations, ranked the citations in each cluster, and generated a set of keywords and MeSH terms to describe the common theme of each cluster. Measurements: Several possible ranking functions were compared, including ci...
متن کاملModel Formulation: A Document Clustering and Ranking System for Exploring MEDLINE Citations
OBJECTIVE A major problem faced in biomedical informatics involves how best to present information retrieval results. When a single query retrieves many results, simply showing them as a long list often provides poor overview. With a goal of presenting users with reduced sets of relevant citations, this study developed an approach that retrieved and organized MEDLINE citations into different to...
متن کاملMedline Document Clustering with Semi-Supervised Spectral Clustering Algorithm
To clustering biomedical documents, three different types of information’s are used. They are local content (LC),global content(GC) and mesh semantic(MS).In previous method only one are two types of information are cluster using Constraints and distance based algorithm. But in proposed system we used Semi Supervised clustering algorithm. It made most of the noisy constraints to improve clusteri...
متن کاملEnhancing MEDLINE document clustering by incorporating MeSH semantic similarity
MOTIVATION Clustering MEDLINE documents is usually conducted by the vector space model, which computes the content similarity between two documents by basically using the inner-product of their word vectors. Recently, the semantic information of MeSH (Medical Subject Headings) thesaurus is being applied to clustering MEDLINE documents by mapping documents into MeSH concept vectors to be cluster...
