Web Service Mediation Through Multi-level Views

2008-10-15T12:16:06Z

Abstract. The web Service MEDiator system (WSMED) provides general query capabilities over data accessible through web services by reading WSDL meta-data descriptions. Based on imported meta-data, the user can define views that extract data from the results of calls to web service operations. The views can be queried using SQL. The views are specified in terms of declarative queries that access di...

2009-11-07T06:13:04Z

Content-based indexing and retrieval has emerged as an important area in computer vision and multimedia computing. Current solutions for searching image data primarily deal with associated text and low-level image features. Humans tend to use high-level concepts in everyday life; user queries are typically based on higher-level semantics and not low-level image features. However, what current comp...

In this article, we are discussing our experience with Internet use and different types of electronic study mat...

A Unified Framework for e-Commerce Systems Development: Business Process Patterns Perspective

2009-11-07T13:37:14Z

In electronic commerce, systems development is based on two fundamental types of models, business models and process models. A business model is concerned with value exchanges among business partners, while a process model focuses on operational and procedural aspects of business communication. Thus, a business model defines the what in an e-commerce system, while a process model defines the how. ...

Implementation of Ontology Based Business Registries to Support e-Commerce

2009-07-25T09:30:01Z

The Business Registries are one of the key elements in the Business to Business (B2B) transaction process in e-Commerce. It acts as knowledge centers by offering services to different business parties to collaborate their business processes in an effective manner. Currently it is challenging to extract accurate information needed by a business party who is querying a registry on a particular indus...

This paper proposes an approach for indexing a collection of multimedia clips by a speaker in an audio track. A Bayesian Information Criterion (BIC) procedure is used for segmentation and Mel-Frequency Cepstral Coefficients (MFCC) are extracted and sampled as metadata for each segment. Silence detection is also carried out during segmentation. Gaussian Mixture Models (GMM) are trained for each spe...

In this paper, we handle database reverse engineering. The main motivation to carry-out this study is the fact that the maintenance of an existing database depends on the depth of understanding of its characteristics. Such an understanding is easily lost when the developers disperse; this is mostly the case with legacy databases. We concentrate on solutions to the case of having a legacy database ...
