Research ArticleOpen accessIn the abstractComparison of Question Answering Systems Based on Ontology and Semantic Web in Different EnvironmentS. Kalaivani, K. DuraiswamyProblem statement: Question Answering (QA) system is taking an important role in current search engine optimization concept. Natural language processing technique is mostly implemented in QA system for asking user’s question and several steps are also followed for conversion of questions to query form for getting an exact answer. Approach: This paper surveys different types of question answering system based … …Journal of Computer Science, Vol. 8, Issue 9 · 9 Aug 2012 · 8,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Bayesian Nearest Neighbor Search Using Marginal Object Weight Ranking Scheme in Spatial DatabasesK. Balasaravanan, K. DuraiswamyProblem statement: A database that is optimized to store and query data that is related to objects in space, including points, lines and polygons is called spatial database. Identifying nearest neighbor object search is a vital part of spatial database. Many nearest neighbor search techniques such as Authenticated Multi-step NN (AMNN), Superseding Nearest Neighbor (SNN) search, Bayesian Nearest Neighbor (BNN) … …Journal of Computer Science, Vol. 8, Issue 8 · 30 Jul 2012 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractContent Based Medical Image Retrieval with Texture Content Using Gray Level Co-occurrence Matrix and K-Means Clustering AlgorithmsB. Ramamurthy, K. R. ChandranProblem statement: Recently, there has been a huge progress in collection of varied image databases in the form of digital. Most of the users found it difficult to search and retrieve required images in large collections. In order to provide an effective and efficient search engine tool, the system has been implemented. In image retrieval system, there is no methodologies … …Journal of Computer Science, Vol. 8, Issue 7 · 24 May 2012 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Page Ranking Algorithm for a Personalized Web SearchJ. Jayanthi, K. S. JayakumarProblem statement: Information on the web is growing exponentially. Today, traditional search engines provide results mainly based on the user’s query. Though the context of the query varies, the returned result seems to be same for all users. Accordingly users are expected to search for the relevant results, which is an added overhead to the users. Approach: We propose a … …Journal of Computer Science, Vol. 8, Issue 7 · 12 May 2012 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractContext Disambiguation Based Semantic Web Search for Effective Information RetrievalM. Barathi, S. ValliProblem statement: Search queries are short and ambiguous and are insufficient for specifying precise user needs. To overcome this problem, some search engines suggest terms that are semantically related to the submitted queries, so that users can choose from the suggestions based on their information needs. Approach: In this study, we introduce an effective approach that captures the user’s specific … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method of Generating Index Label for Dynamic XML DataJayanthi Paramasivam, Tamilarasi AngamuthuProblem statement: The processing of the XML queries needs an efficient indexing method. The index generation includes the labeling of the nodes. But for the dynamic data, when the changes are made, the re-computation of the labeling is needed. Approach: Based on the structural indexing used the performance of the query processing system will be affected. The dynamic XML document … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Novel Human Immunodeficiency Virus-1 Integrase Inhibitors by Shape-Based Virtual ScreeningT.K. Omprakash, A. Thamarai Selvan, A. Shahul Hameed, S.P. GeethaProblem statement: Human Immunodeficiency Virus-1 (HIV-1) is causative agent of the immune system disease, Acquired Immune Deficiency Syndrome (AIDS). Majority of anti-HIV drugs target reverse transcriptase and protease enzymes. Toxicity and development of multidrug resistant HIV-1 virus strains are the reasons for studying new targets in HIV-1 replication process for identifying novel inhibitor with low toxicity and high activity. Approach: … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Dec 2010 · 7,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling Label Size Increment of Efficient XML Encoding and Labeling Scheme in Dynamic XML UpdateMeghdad Mirabi, Hamidah Ibrahim, Ali Mamat et al.Problem statement: In order to facilitate XML query processing, labeling schemes are used to determine the structural relationships between XML nodes. However, labeling schemes have to reliable the existing nodes or recalculate the label values when a new node is inserted into the XML document during XML update process. EXEL as a labeling scheme is able to remove relabeling for … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse Fusion in Multi-Agent EnvironmentFereshteh-Azadi Parand, Nasrollah Moghaddam Charkari, Sara AfrasyabianMulti agent environment are often complex, while each member of agent community has vision about only a part of the environment. In such environment, information fusion of agent community is vital to attain a better accuracy or quality of information. Agents have different ability and can access to information sources with different degree of credibility. As a result, information which … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Methods of Neutrosophic Logia to Answer Queries in Relational DatabaseSmita Rajpal, M. N. Doja, Ranjit BiswasIn this study the authors propose a new method of intelligent search called Neutrosophic-search to find the most suitable match for the predicates to answer any imprecise query made by the database users. It is also to be mentioned that the Neutrosophic-search method could be easily incorporated in the existing commercial query languages of DBMS to serve the lay users … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,911 accessesView PDFCite
