Research ArticleOpen accessIn the abstractSeparable Watermarking Technique Using the Biological Color ModelDavid Nino, Moussa Abdallah, Bassam HammoProblem statement: The issue of having robust and fragile watermarking is still main focus for various researchers worldwide. Performance of a watermarking technique depends on how complex as well as how feasible to implement. These issues are tested using various kinds of attacks including geometry and transformation. Watermarking techniques in color images are more challenging than gray images in terms … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,611 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Question Answering System for the Arabic LanguageGhassan Kanaan, Awni Hammouri, Riyad Al-Shalabi, Majdi SwalhaWe depict the architecture of a question answering system and methodically evaluate contributions of different system components to accuracy. The system differs from most question answering systems in its dependency on data redundancy rather than complicated linguistic analyses of either questions or contender answers. Because a wrong answer is often worse than no answer. A Question Answering (QA) system is … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,922 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMining Fuzzy Weighted Browsing Patterns from Time Duration and with Linguistic ThresholdsTzung-Pei Hong, Ming-Jer Chiang, Shyue-Liang WangWorld-wide-web applications have grown very rapidly and have made a significant impact on computer systems. Among them, web browsing for useful information may be most commonly seen. Due to its tremendous amounts of use, efficient and effective web retrieval has become a very important research topic in this field. Techniques of web mining have thus been requested and developed to … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,397 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApproaches for Categorization of Reusable Software ComponentsParvinder Singh Sandhu, Janpreet Singh, Hardeep SinghReuse repositories manager manages the reusable software components in different categories and needs to find the category of reusable software components. In this paper, we have used different pure and hybrid approaches to find the domain relevancy of the component to a particular domain.

Research ArticleOpen accessIn the abstractA New Indexing Technique for Information Retrieval Systems Using Rhetorical Structure Theory (RST)Muhammad Shoaib, Abad Ali ShahEffective information retrieval requires an efficient indexing technique. With the availability of huge volume of information, it has become necessary to capture the semantic of the document, which is almost impossible with the existing techniques. Moreover in the existing technique the weights once assign are remains unchangeable through out the cycle. In this paper an indexing technique assignment using Rhetorical … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 7,406 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSPEECH/MUSIC CLASSIFICATION USING WAVELET BASED FEATURE EXTRACTION TECHNIQUESThiruvengatanadhan Ramalingam, P. DhanalakshmiAudio classification serves as the fundamental step towards the rapid growth in audio data volume. Due to the increasing size of the multimedia sources speech and music classification is one of the most important issues for multimedia information retrieval. In this work a speech/music discrimination system is developed which utilizes the Discrete Wavelet Transform (DWT) as the acoustic feature. Multi … …Journal of Computer Science, Vol. 10, Issue 1 · 8 Nov 2013 · 6,841 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMedical Image Classification Using Genetic Optimized Elman NetworkT. Baranidharan, D. K. GhoshProblem statement: Advancements in the internet and digital images have resulted in a huge database of images. Most of the current search engines found in the web depends only on images that can be retrieved using metadata, which generates a lot of unwanted results in the results got. Content-Based Image Retrieval (CBIR) system is the utilization of computer vision techniques … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 24 Nov 2011 · 7,717 accessesView PDF Cite
