Due to the information on the Web being tremendous, dynamic and irregular, it is difficult to search and integrate information from the Web. This paper proposes a Web information extraction algorithm based on Ontology and DOM tree. The areas are accurately found out and the interested information is extracted exactly by information extraction rules generated by ontology. Furthermore this algorithm...
For the current web information extraction can't adapt to the various page structures, this paper proposes a Web Information Extraction Method based on News Domain Ontology. The areas are accurately found out and the interested information was extracted exactly based on information extraction rules which is generated by news domain ontology. Using the technology of page processing, page conversion,...
We have developed a head gesture controlled electric wheelchair system to aid persons with severe disabilities. Realtime range information obtained from a stereo camera is used to locate and segment the face images of the user from the sensed video. We use an Isomap based nonlinear manifold learning map of facial textures for head pose estimation. Our system is a non-contact vision system, making...
