Being these resources highly heterogeneous (from individual users to whole organizations or experiment tools and workflows), this paper presents a trust and reputation framework that integrates a number of information sources to produce a comprehensive evaluation of trust and reputation by clustering resources having similar capabilities of successfully executing a specific job. Here, trust and reputation are considered as Quality of Service (QoS) parameters, and are asserted on the operative context of resources, a concept expressing the resources capability of providing trusted services within collaborative scientific applications. Specifically, the framework exploits the use of distributed brokers that support interaction trust and the creation of VOs from existing scientific organizations. A broker is a distributed software module launched at some node of the Grid that makes use of resources and communicates with other brokers to perform specific reputation services. In turn, each broker contributes to maintain a dynamic and adaptive reputation assessment within the Grid in a collaborative and distributed fashion. The proposed framework is empirically implemented by adopting a SOA approach and results show its effectiveness and its possible integration in a scientific Grid.","PeriodicalId":180106,"journal":{"name":"2009 Third International Conference on Research Challenges in Information Science","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126463944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data warehouses (DW), at the core of DIS, integrate and historize collections of data often designed starting from the operational components of the Information Systems (IS). Methods, techniques and tools widely used in the industry to engineer DIS focus, mostly, on designing DW models. However a few approaches were recently proposed to deal with the early phase of DIS development and maintenance, i.e. Requirements Engineering (RE). As for other specific kinds of systems, the expectation is that better value shall be delivered to DIS users (i.e. different sorts of decision maker such as executives, or managers, as well as control managers or operational) if more effort is spent on analyzing their requirements in early phase of DIS engineering projects. However, DIS is very specific kinds of systems. Therefore the question is how specific should RE approaches be when developing a DIS? To addresses this question, we undertook an in depth analysis of (a) the specificities of DIS systems that shall have an impact on RE approach (b) expectations from DIS project stakeholders, and (c) gap analysis of DIS specific RE approaches and traditional RE approaches. The analysis is structured around the three main axes of RE approaches, i.e. formalization, specification, and consistency. The paper shows that although on a fundamental level RE for DIS approaches does not show conceptual differences with traditional RE for IS approaches, some differences exist in the way of working.","PeriodicalId":180106,"journal":{"name":"2009 Third International Conference on Research Challenges in Information Science","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123498297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The peculiar characteristics of Arabic handwriting have added an extra challenging dimension in developing such systems. This paper presents a novel holistic technique for segmenting and classifying HAH manuscripts. The classification of HAH manuscripts is performed in several steps. First, the HAH manuscript's image is segmented into words, and then each word is segmented into its connected parts. Due to the existing overlap between the adjacent connected parts of a single word, we developed a stretching algorithm to increase the gap between them and thus improve their segmentation. Second, several structural and statistical features, which are devised for Arabic text, are extracted from these connected parts and then combined to represent a word with one consolidated feature vector. Finally, a neural network is used to learn and classify the input vectors into word classes. The extraction of structural and statistical features from the individual connected parts, as compared to the extraction of these features from the whole word, improved the performance of the system significantly.","PeriodicalId":180106,"journal":{"name":"2009 Third International Conference on Research Challenges in Information Science","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126548634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From the user point of view, the access to information can be carried out in a deliberate way through an information retrieval system, or in a passive way through an information filtration system. CISMeF (Catalogue and Index of the French-speaking Medical Sites) is a health portal aiming to catalogue and index the most important French-speaking institutional health information sources in order to make them available to health professionals, medical students and the general public. The Internet resources were manually indexed and have remained mono-terminological from 1995 to 2007 originally based exclusively on the MeSH thesaurus (Medical Subject Headings). Categorization allows a contextual information retrieval parameterized according to the user's needs. In 2007, the CISMeF team directed its objectives towards a multi-terminological universe by the integration of the medical data heterogeneous sources into its back-office. To date, the practical application is the creation of a bilingual (French/English) drug information portal in order to facilitate the user information retrieval about drugs.","PeriodicalId":180106,"journal":{"name":"2009 Third International Conference on Research Challenges in Information Science","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130724937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
