The database community is exploring more and more multidisciplinary avenues:
Data semantics overlaps with ontology management; reasoning tasks venture into
the domain of artificial intelligence; and data stream management and
information retrieval shake hands, e.g., when processing Web click-streams.
These new research avenues become evident, for example, in the topics that
doctoral students choose for their dissertations. This paper surveys the
emerging multidisciplinary research by doctoral students in database systems
and related areas. It is based on the PIKM 2010, which is the 3rd Ph.D.
workshop at the International Conference on Information and Knowledge
Management (CIKM). The topics addressed include ontology development, data
streams, natural language processing, medical databases, green energy, cloud
computing, and exploratory search. In addition to core ideas from the workshop,
we list some open research questions in these multidisciplinary areas
