The research concentrates on data mining from structured documents. More precisely, the research problem involves information retrieval and clustering from XML documents conforming to the same schema. The potential of combining various search and clustering techniques in order to comprehend document collections is considered. Various index structures, similarity measures, clustering algorithms and ranking techniques are reviewed in the theoretical part of this thesis. In the empirical part the ExtMiner-application is developed, supporting searching, clustering and visualization for various XML document collections.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2008-01-08T09:30:29Z (GMT).
