Research ArticleOpen accessIn the keywordsA 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 · 6,835 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIndex Financial Time Series Based on Zigzag-Perceptually Important PointsAli Selamat, Chawalsak Phetchanchai, Tanzila Saba, Amjad RehmanProblem statement: Financial time series were usually large in size, unstructured and of high dimensionality. Since, the illustration of financial time series shape was typically characterized by a few number of important points. These important points moved in zigzag directions which could form technical patterns. However, these important points exhibited in different resolutions and difficult to determine. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 12 · 2 Nov 2010 · 9,464 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficient Physical Organization of R-Trees Using Node ClusteringF. Sagayaraj Francis, P. ThambiduraiR-Tree is a multidimensional indexing structure that forms basis for all the multidimensional indexing structures based on data partitioning. A number of attempts have been made in the past to improve the performance of R-Tree by manipulating the tree parameters and the data parameters. But hardly any attempt had been made to use external parameters such as disk parameters to … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,627 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Dynamic Weight Assignment Approach for Index TermsKamel E. Haouam, Farhi MarirCurrently in the development of Informational Retrieval (IR) systems, a set of keywords represents the semantics of a text document and after assigning weights to the set of keywords, they are used for indexing, searching and retrieval purposes. The current approaches for assigning weights are provided by an IR model that is used by an IR system. The main objective … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,943 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesigning and Building an Automatic Information Retrieval System for Handling the Arabic DataIbrahiem M.M. El Emary, Ja'far AtwanThis paper aimed to design and build an Automatic Information Retrieval System to handle the Arabic data. Also, this paper presents some type of comparison between the retrieval results using the vector space model in two different indexing methods: the full-ward indexing and the root indexing. The proposed Automatic Information Retrieval system was implemented and built using a traditional model … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Different Query Expansion Techniques for Arabic Text Retrieval SystemAysh Alhroob, Hayel Khafajeh, Nisreen InnabThe word mismatch problem is fundamental to Information retrieval. Query expansion process helps to overcome this problem. Based on the Arabic corpuses, the comparisons between two query expansion techniques (global and local query) have been conducted to determine the query effectiveness. First one represents the local context analysis which represents a local method, while a global method was the second … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 6,885 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCOMPARING THE PERFORMANCE OF SEMANTIC IMAGE RETRIEVAL USING SPARQL QUERY, DECISION TREE ALGORITHM AND LIREMagesh, ThangarajThe ontology based framework is developed for representing image domain. The textual features of images are extracted and annotated as the part of the ontology. The ontology is represented in Web Ontology Language (OWL) format which is based on Resource Description Framework (RDF) and Resource Description Framework Schema (RDFS). Internally, the RDF statements represent an RDF graph which provides the … …Journal of Computer Science, Vol. 9, Issue 8 · 8 Jul 2013 · 6,705 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKey Based Random Permutation (KBRP)Shakir M. Hussain, Naim M. AjlouniThis study introduces a method for generating a particular permutation P of a given size N out of N! permutations from a given key. This method computes a unique permutation for a specific size since it takes the same key; therefore, the same permutation can be computed each time the same key and size are applied. The name of random … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Facial Expression Recognition Accuracy Through Haar Cascade-Based Feature ExtractionThambusamy Velmurugan, Lakshminarayanan MeenaFacial Expression Recognition (FER) has a significant interest because of its increased applications in Human-Computer Interaction (HCI), like video interactions, emotion analysis, image indexing, and retrieval and many more. In the discipline of computer vision, pattern recognition, and artificial intelligence FER has become an extremely active research topic. A crucial component of FER systems is feature extraction, which involves identifying … …Journal of Computer Science, Vol. 21, Issue 12 · 21 Jan 2026 · 1,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractPedagogical Resources Indexation Based on Ontology in Intelligent Recommendation System for Contents Production in d-Learning EnvironmentBrahim Faqihi, Najima Daoudi, Imane Hilal, Rachida AjhounWe witness, today, a strong evolution of learning environments. In parallel, a problem has emerged, consisting in how to capitalize the production of resources when switching from one environment to another. The heterogeneity of the environments, the evolution of the platforms and the will to reuse the educational resources already produced pushed us to design an intelligent system based on … …Journal of Computer Science, Vol. 16, Issue 7 · 19 Aug 2020 · 6,703 accessesView PDFCite
