An important issue arising from Web databases fuzzy query is how to rank the answers from data sources, this paper investigates the problem of ranking the answers by taking advantage of the user's needs and preferences. Firstly, based on fuzzy set theory, a satisfaction degree ranking method, which ranks the answer according to the tuple's satisfaction degree to the fuzzy query, is presented. Next,...
Thumbnail cropping helps improve thumbnail readability by cropping images before shrinking them. In this paper we propose a learning based method for automatic thumbnail cropping. To this end, we use a support vector machine to learn a discriminative model that simultaneously captures the saliency distribution and spatial priors. The model is then used to determine the best cropping rectangle. The...
This paper proposes a novel window operator, pattern-based window, for data stream processing. By using pattern-based windows, user-specified complex events can be extracted from data streams under the framework of continuous query language (CQL), which integrates the current data stream processing and event stream processing. In this paper, the pattern-based window is formally defined and the query...
