It encompasses database management areas such as data warehousing and schema versioning; information retrieval areas such as Web semantics and topic detection; and core data mining areas, e.g., knowledge based systems, uncertainty management, and time-series mining. This becomes particularly evident in the topics that Ph.D. students choose for their dissertation. As the grass roots of research, Ph.D. dissertations point out new avenues of research, and provide fresh viewpoints on combinations of known fields. In this article we overview some recently proposed developments in the domain of knowledge discovery and its related spheres. Our article is based on the topics presented at the doctoral workshop of the ACM Conference on Information and Knowledge Management, CIKM 2011.<\/jats:p>","DOI":"10.1145\/2783702.2783708","type":"journal-article","created":{"date-parts":[[2015,5,26]],"date-time":"2015-05-26T14:36:05Z","timestamp":1432650965000},"page":"46-49","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["New Research Directions in Knowledge Discovery and Allied Spheres"],"prefix":"10.1145","volume":"16","author":[{"given":"Anisoara","family":"Nica","sequence":"first","affiliation":[{"name":"Research and Development Sybase, An SAP Company, Waterloo, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabian M.","family":"Suchanek","sequence":"additional","affiliation":[{"name":"Otto Hahn Research Group \"Ontologies\" Max Planck Institute for Informatics, Saarbr\u00fccken, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aparna S.","family":"Varde","sequence":"additional","affiliation":[{"name":"Montclair State University, Montclair, NJ"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2015,5,21]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065012"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065013"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065019"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065020"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065009"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065008"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2065003.2065015"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2063576.2064049"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/1942776.1942786"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/1871437.1871795"},{"volume-title":"Proceedings of the Second Ph.D. Workshop in CIKM, PIKM 2008, 18th ACM Conference on Information and Knowledge Management, ACM CIKM 2008","author":"Roy P.","key":"e_1_2_1_11_1","unstructured":"P.
