Yaser A. M. Al-Lahham , "Scalable Self-Organizing Structured P2P Information Retrieval Model Based on Equivalence Classes", The International Arab Journal of Information Tech , Vol. 11, No 1
01/01/2014
Abstract: This paper proposes a new autonomous self-organizing content-based node clustering peer to peer information retrieval (P2PIR) model. This model uses incremental transitive document-to-document similarity technique to build Local Equivalence Classes (LECes) of documents on a source node. Locality Sensitive Hashing scheme is applied to map a representative of each LEC into a set of keys which will be published to hosting node(s). Similar LECes on different nodes form Universal Equivalenc

Mobile computing environment is subject to the constraints of bounded network bandwidth, frequently encountered disconnections, insufficient battery power, and system asymmetry. To meet these constraints and to gain high scalability, data broadcasting has been proposed on data transmission techniques. However, updates made to the database in any broadcast cycle are deferred to the next cycle in order to appear to mobile clients with lower data currency. The main goal of this paper is to enhance

Abstract: Arabic language has a complex morphological structure, which makes it hard to select index terms for an IR system. The complexity of the Arabic morphology caused by multimode terms, using diacritics, letters have different forms according to its location in the word and affixes can be added at all locations in a word. Several methods were proposed to overcome these problems; such as root extraction and light stemming. Light stemming show better retrieval efficiency, Light10 is the best
