Research ArticleOpen accessPhrase in the titleEvaluation 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 PDF Cite

Research ArticleOpen accessPhrase in the titleInteractive and Automatic Query Expansion: A Comparative Study with an Application on ArabicGhassan Kanaan, Riyad Al-Shalabi, Sameh Ghwanmeh, Basel Bani-IsmailMuch attention has been paid to the relative effectiveness of Interactive Query Expansion (IQE) versus Automatic Query Expansion (AQE). This research has been shown that automatic query expansion (collection dependent) strategy gives better performance than no query expansion. The percentage of queries that are improved by AQE strategy is 57% with average precision equal to 43.2. Compared against AQE (collection … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,480 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsImproving Question Answering System based on a Hybrid TechniqueAyatallah Gamal Abass, Sameh Abd El-Ghany, Ahmed Abo ElfetohQuestion Answering (QA) is a specialized form of information retrieval characterized by information needs that are expressed as natural language statements or questions. Query expansion is an approach which is used to extend question key words with new related words that are not included in question. In this study, anew association rule based question processing model is introduced. This model … …Journal of Computer Science, Vol. 14, Issue 9 · 15 Aug 2018 · 7,979 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Approach to Query Reformulation in Cross Lingual Information Retrieval Emphasizing Term PlacementAmit Asthana, Sanjay K. DwivediThe effectiveness of retrieving relevant information is often hindered by ambiguous and short queries, compounded by often imprecise initial translation in Cross Lingual Information Retrieval (CLIR). These limitations are still a challenge for Query Reformulation (QR) techniques, which primarily focus on selecting effective expansion terms but generally neglect the impact of determining their optimal placement within the query. This paper … …Journal of Computer Science, Vol. 22, Issue 2 · 23 Feb 2026 · 1,658 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuery Translation using Concepts Similarity Based on Quran Ontology for Cross-Language Information RetrievalZulaini Yahya, Muhamad Taufik Abdullah, Azreen Azman, Rabiah Abdul KadirIn Cross-Language Information Retrieval (CLIR) process, the translation effects have a direct impact on the accuracy of follow-up retrieval results. In dictionary-based approach, we are dealing with the words that have more than one meaning which can decrease the retrieval performance if the query translation return an incorrect translations. These issues need to be overcome using efficient technique. In this … …Journal of Computer Science, Vol. 9, Issue 7 · 21 Jun 2013 · 7,469 accessesView PDF Cite
