Research ArticleOpen accessIn the abstractAn Automatic Collocation Extraction from Arabic CorpusAbdulgabbar Mohammad Saif, Mohd J.A. AzizProblem statement: The identification of collocations is very important part in natural language processing applications that require some degree of semantic interpretation such as, machine translation, information retrieval and text summarization. Because of the complexities of Arabic, the collocations undergo some variations such as, morphological, graphical, syntactic variation that constitutes the difficulties of identifying the collocation. Approach: We used the … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeuristic Lemmatization for Arabic Texts Indexation and ClassificationFaten Khalfallah Hammouda, Abdelsalam Abdelhamid AlmarimiProblem statement: This study proposed a system based on a heuristic lemmatization for Arabic text indexation and classification. This research is needed for a lot of NLP applications such as the research of information and automatic abstract. This system was not related to any linguistic rule. The proposed method was limited to five different domains: Sports, medicine, politics, economics and … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractToponym Disambiguation by Arborescent RelationshipsImene Bensalem, Mohamed-Khireddine KholladiProblem statement: The way of referring to a place in the geographical space can be formal, based on the spatial coordinates, or informal, which we use in natural language by using toponyms (place names). A toponym can represent several geographical places. This ambiguity made problematic its conversion towards a unique formal representation. Toponym disambiguation in text is the task of … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Approaches for Predicting Break Indices in Mandarin Speech SynthesisShao Yan-qiu, Zhao Yong-zhen, Han Ji-qing, Liu TingThis study adopts a large-scale corpus with five-tier break indices annotated according to C-TOBI. Based on it, several approaches, N-gram, Markov model and decision tree learning are applied to predict break indices automatically for unrestricted mandarin text. These approaches differ mutually not only in model, but also on features and even part-of-speech tag size. A deep comparison and analysis among … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 6,216 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordNew Information Content Glossary Relatedness (ICGR) Approach for Short Text Similarity (STS) TasksAli Muftah BenOmran, Mohd Juzaiddin Ab AzizThe measurement of the relatedness of word semantics based on complementary Wikipedia and WordNet-based methods takes two forms, combined and integrative, which are aimed at increasing the semantic space between related words. However, each form has its own set of issues regarding its components and the strategy that is used to combine and integrate corpus-based and knowledge-based methods. In the … …Journal of Computer Science, Vol. 15, Issue 6 · 5 Jun 2018 · 8,004 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Control of Fundamental Frequency Contour for Hidden Markov Model-Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In the conventional HMM-based speech synthesis system for Thai, there is no control of fundamental frequency control in the synthesis stage. The tone correctness of the synthesized speech is unacceptable due to the imbalance of training data of all tones. Approach: This study proposes a mathematical model to control the F0 contour of the synthesized speech. This control … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,057 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation 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 · 6,889 accessesView PDFCite
