Our work in this field develops the design and implementation of a Multi-Agent Systems Based on Dynamic Case Based Reasoning which can initiate learning and provide an individualized follow-up of learner. When interacting with the platform, every learner leaves his/her traces in the machine. These traces are stored in a basis under the form of scenarios which enrich collective past experience. The system monitors, compares and analyses these traces to keep a constant intelligent watch and therefore detect difficulties hindering progress and/or avoid possible dropping out. The system can support any learning subject. The success of a case-based reasoning system depends critically on the performance of the retrieval step used and, more specifically, on similarity measure used to retrieve scenarios that are similar to the course of the learner (traces in progress). We propose a complementary similarity measure, named Inverse Longest Common Sub-Sequence (ILCSS). To help and guide the learner, the system is equipped with combined virtual and human tutors.","PeriodicalId":120664,"journal":{"name":"2012 Colloquium in Information Science and Technology","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132523570","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 online opinion has become the object of studies in many research areas; especially that called “Opinion Mining and Sentiment Analysis”. Several interesting and advanced works were performed on few languages (in particular English). However, there were very few studies on some languages such as Arabic. This paper presents the study we have carried out to address the problem of unbalanced data sets in supervised sentiment classification in an Arabic context. We propose three different methods to under-sample the majority class documents. Our goal is to compare the effectiveness of the proposed methods with the common random under-sampling. We also aim to evaluate the behavior of the classifier toward different under-sampling rates. We use two different common classifiers, namely Naïve Bayes and Support Vector Machines. The experiments are carried out on an Arabic data set that we have built from Aljazeera's web site and labeled manually. The results show that Naïve Bayes is sensitive to data set size, the more we reduce the data the more the results degrade. However, it is not sensitive to unbalanced data sets on the contrary of Support Vector Machines which is highly sensitive to unbalanced data sets. The results show also that we can rely on the proposed techniques and that they are typically competitive with random under-sampling.","PeriodicalId":120664,"journal":{"name":"2012 Colloquium in Information Science and Technology","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116379507","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}

However, the data quality is not the only concern; requirements related for example to security, performance and operability are also vital. Most existing approaches for conducting DW projects deal with the functional and nonfunctional requirements in a complete separate way. The lack of a global approach that gather concurrently both aspects from the requirements analysis to the conceptual design causes that many DW projects fail to meet their goals in satisfying users' needs and expectations. This work is the first step towards the development of a single framework that encompass a unified approach that allows us to get design information for the future datawarehouse multidimensional model on the basis of both functional and non-functional requirements. We will present the methods we adopted to achieve this goal and the enhancement we have made by integrating three additional aspects in the requirements analysis workflow, namely organizational, decisional and business process views. We select the telecom industry for our case study to demonstrate the viability of our approach.","PeriodicalId":120664,"journal":{"name":"2012 Colloquium in Information Science and Technology","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128516079","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}

This work focuses on the business repository used as a starting point by the generation process of LMSGENERATOR. It is therefore a re-engineering process of learning management systems functional requirements to produce an extensible business model repository whose components are reusable, adaptable, flexible, integrating the various and global phases of the Open distance learning (ODL) and representing a criteria of adaptability to different user categories. Generic models with adaptability criteria are delivered to compose the LMS business repository. Each element of this repository (business model) is composed by three sub-models: data model, semantic model and visual model. These sub models are part of a transformation process that respected the art of model-driven engineering to produce a component model independently of the developmental technology. The generation process of component models, business components and the building process of complete solutions are represented to show the importance of this business repository in the LMSGENERATOR process.","PeriodicalId":120664,"journal":{"name":"2012 Colloquium in Information Science and Technology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211200","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}
