an abstract optimization problem arising from biomolecular sequence analysis. For a sequence A of pairs (ai, wi) for i = 1, . . . , n and wi > 0, a segment A(i, j) is a consecu...
The integer least squares problem arises from many applications such as communications, cryptography, and GPS. In this paper, we consider the sphere decoding method in communicati...
We investigate the problem of mining closed sets in multi-relational databases. Previous work introduced different semantics and associated algorithms for mining closed sets in mu...
With the development of the Internet and wide applications of databases, the databases providers are worrying about their ownership of the databases. Combined with the digital wat...
Paraphrase recognition is a critical step for natural language interpretation. Accordingly, many NLP applications would benefit from high coverage knowledge bases of paraphrases. ...
