Semantic Subgroup Discovery Systems and Workflows in the SDM-Toolkit

Abstract

This paper addresses semantic data mining, a new data mining paradigm in which ontologies are exploited in the process of data mining and knowledge discovery. This paradigm is introduced together with new semantic subgroup discovery systems SDM-search for enriched gene sets (SEGS) and SDM-Aleph. These systems are made publicly available in the new SDM-Toolkit for semantic data mining. The toolkit is implemented in the Orange4WS data mining platform that supports knowledge discovery workflow construction from local and distributed data mining services. On the basis of the experimental evaluation of semantic subgroup discovery systems on two publicly available biomedical datasets, the paper results in a thorough quantitative and qualitative evaluation of SDM-SEGS and SDM-Aleph and their comparison with SEGS, a system for enriched gene set discovery from microarray data.

Semantic Web in data mining and knowledge discovery: A comprehensive survey

“…The system was extended in the SegMine system, which allows exploratory analysis of microarray data, performed through semantic subgroup discovery by SEGS [177], followed by link discovery and visualization by Biomine [178], an integrated annotated bioinformatics information resource of interlinked data. The SEGS system was later extended to two general semantic subgroup discovery systems, SDM-SEGS and SDM-Aleph [179][180][181]. Finally, the authors introduced the Hedwig system [182], which overcomes some of the limitations of the previous systems.…”

“…In this paper, we employ the widely-used Aleph ILP system [15,19,21]. Aleph applies a two-step approach to learn a clause.…”

“…Alguns autores relatam, em seus trabalhos, como as ontologias estão sendo utilizadas para melhorar os resultados dos métodos de mineração de dados por regras de associação com a adoção de descritores semânticos (BELLANDI et al, 2007;FERRAZ, 2008;MARINICA, 2010;COUTO;SILVA, 2011;COELHO, 2012;VAVPETIC;LAVRAC, 2012;HAMANI et al, 2014;RIBEIRO, 2010).…”
