This paper presents an opinion analysis system developed by CUHK_PolyU_Tsinghua Web Information Analysis Group (WIA), namely WIA-Opinmine, for NTCIR-7 MOAT Task. Different from most existing opinion mining systems, which recognize opinionated sentences as one-step classification procedure, WIAOpinmine adopts a multi-pass coarse-fine analysis strategy. A base classifier firstly coarsely estimate...

Abstarct. Inspired by the recent developments in attribute-based encryption, in this paper we propose threshold attribute-based signatures (t-ABS). In a t-ABS, signers are associated with a set of attributes and verification of a signed document against a verification attribute set succeeds if the signer has a threshold number of (at least t) attributes in common with the verification attribute...
