Movement change beyond the duration of time and the variations of object appearance becomes an interesting topic for research in computer vision. Object behavior can be recognized through movement change on video. During the recognition of object behavior, the target and the trace of an object in a video must be determined in the sequence of frames...

This research proposes the development of Arabic language service. It is a servlet-based Webservice which provides a translation from English into Arabic, using techniques to develop Webservices such as Restful and API in Java language. This API is part of Language Grid, aproject in Japan to collect, share and combine as many language resources as...

One of the most important tasks for business entity is to make its service available for users' requests through the web. The semantic description of business entity needs to be developed to enhance the matching process between users' requests and the best advertised services.
