Opinion mining has become recently a major research topic. A wide range of techniques have been proposed to enable opinion-oriented information seeking systems. However, little is...
We propose a partitioning scheme for similarity search indexes that is called Maximal Metric Margin Partitioning (MMMP). MMMP divides the data on the basis of its distribution pat...
Most of existing methods of keyword search over relational databases find the Steiner trees composed of relevant tuples as the answers. They identify the Steiner trees by discove...
In this paper we present a general framework to study sequences of search activities performed by a user. Our framework provides (i) a vocabulary to discuss types of features, mod...

The problem of measuring similarity between web pages arises in many important Web applications, such as search engines and Web directories. In this paper, we propose a novel neig...
We propose XQGen, a stand-alone, algebra-based XPath generator to aid engineers in testing and improving the design of XML query engines. XQGen takes an XML schema sketch and user...
