context information and semantic similarity together. We searched a series of context structures for keywords in a sentence. Experiment has been carried out to show the effectiveness of our method.
The amount of multimedia information is rapidly increasing due to digital cameras. To interpret semantic of image, many researcher use keywords as textual annotation. Image semantic information retrieval became attractive for many peoples. Concept recognition is a key problem in semantic information searching. A new
The current grid information retrieval commonly uses the method based on keywords, and the retrieval method depends on the keywords that match their participation in the external form of characters, rather than the concept expressed by their neglect of the semantic information inherent in the word. It brings about
proposing a Scheme to search information semantically over unstructured P2P network, based on ontology. The ontology best described as a formal representation of a set of words within a domain and a relationship between those words rather keywords. The ontology uses Dewey Decimal Code to facilitate the classification taxonomy
Because of ignoring the semantic information inside the keywords, the traditional searching engine based on the key words has low recall and precision. Aiming at this, some semantic retrieval system design ideas and the retrieval process are proposed in this paper.The key technologies-related in semantic retrieval
