of text summarization is accurate identification of keywords from the given textual content. In this paper, the relative performance of three popular algorithms, namely TextRank, LexRank and Latent Semantic Analysis for keyword extraction were investigated by measuring their effectiveness in identifying keywords from
The important step towards Web service implement is the discovery of required services. Traditional Web service uses UDDI, WSDL standards etc. Keywords based searching is used in the traditional service discovery. For needing manual intervention and lack of semantic description, the methods before have low precision
used to process the captured signals. The eye-tracker device that we have implemented uses keywords technology. It has been tested on a set of subjects by using different parameters for the pupil detection algorithm in order to determine the system optimal performances (algorithm running time and accuracy).
