Update summarization is an extension of query-focused multidocument summarization which was launched at DUC 2007. The essential problem of update summarization is to attain the information novelty and topic continuity simultaneously. In this paper, we proposed several Temporal Content Filtering Methods to extract the time-varying information for the update summarization task, while the topic co...

We present a variety of open questions in automatic continuity theory, concentrating on homomorphisms between Banach algebras and derivations from a Banach algebra A into a Banach A-bimodule.

We de…ne combinatorial principles which unify and extend the classical results of Steinhaus and Piccard on the existence of interior points in the distance set. Thus the measure and category versions are derived from one topological theorem on interior points applied to the usual topology and the density topology on the line. Likewise we unify the subgroup theorem by reference to a Ramsey prope...
