For text-query-based keyword spotting from handwritten Chinese documents, the index is usually organized as a candidate lattice to overcome the ambiguity of character segmentation. Each edge in the lattice denotes a candidate character associated with a candidate class. Character similarity (between character and
The number of Web services are growing rapidly on the Internet. Topics of services are becoming various. Semantic-based keyword search is used to retrieve proper services for service consumers. According to the semantic information implied in service database, we build a topic model to cluster and management related
This paper presents method for split-step backward Euler scheme in regime-switching models. We generalize the classical Black-Scholes model to encompass regime-switching properties. The Black-Scholes model is shown to generate significant pricing errors when a regime-switching process governs underlying asset returns. In addition, regime-switching option values are shown to generate implied volatility...
of Amdahl theoretical thresholds. Rainbow options have been valued with several multivariate lattices models programmed according to our parallelization algorithms providing results not found in extant literature in terms of granularity and convergence. Keywords: Rainbow Options, multivariate binomial lattices
The wide diffusion of community tagging sites and related folksonomies has made the knowledge discovery and retrieval still much more urgent topic. If tagging systems allow users to add freely keywords to web resources, clicking on a tag has the side effect of a tag-based query, since enables the users to explore
