Semantic Similarity between Web Documents Using Ontology

The World Wide Web is the source of information available in the structure of interlinked web pages. However, the procedure of extracting significant information with the assistance of search engine is incredibly critical. This is for the reason that web information is written mainly by using natural language, and further available to individual human. Several efforts have been made in semantic similarity computation between documents using words, concepts and concepts relationship but still the outcome available are not as per the user requirements. This paper proposes a novel technique for computation of semantic similarity between documents that not only takes concepts available in documents but also relationships that are available between the concepts. In our approach documents are being processed by making ontology of the documents using base ontology and a dictionary containing concepts records. Each such record is made up of the probable words which represents a given concept. Finally, document ontology’s are compared to find their semantic similarity by taking the relationships among concepts. Relevant concepts and relations between the concepts have been explored by capturing author and user intention. The proposed semantic analysis technique provides improved results as compared to the existing techniques.

Jitter and Latency Evaluation of Phasors Computation in Power Systems

This paper evaluates Jitter and Latency in a novel technique for computation of Phasors in power systems. The evaluation is done for dynamically computed Phasors based on streamed Sampled Measured Values provide by the Merging Units (MUs) installed in contemporary power substations. In this evaluation, the effects of Jitter and Latency introduced by the communication network on computed Phasor are tested by using two methods of measuring Jitter which are chosen to handle problems of clock offset and drift. Representative results in evaluating of Phasors computation performance are presented in this paper.
