Although these models have already achieved good performance, it has been shown that most of dissatisfaction cases in relevance are due to term mismatch between queries and documents. In this paper, we introduce novel method to compute term frequency based on semantic similarities using distributed representations of words in a vector space (Word Embeddings). Our main goal is to allow distinct but semantically related terms to match each other and contribute to the relevance scores. Hence, Arabic documents are retrieved beyond the bag-of-words paradigm based on semantic similarities between word vectors. The results on Arabic standard TREC data sets show significant improvement over the baseline bag-of-words models.","PeriodicalId":196827,"journal":{"name":"2016 4th IEEE International Colloquium on Information Science and Technology (CiSt)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128868901","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}

In the context of social networks, a community is a set of entities with a lot of interactions among them and little interaction with other sets outside. There are approaches related to static social networks, and others which focus on the dynamic social networks whose structure (actors and links) evolves over time. Static community detection approaches are able to find a division only if a graph is defined for a given time. However, many real graphs have the property to change and evolve over time. That is some nodes and links can appear or disappear during this process of evolution. In order to find communities in such networks we must take into account their different stages of evolution to provide coherent communities not just in a particular point in time, but all along their possible modifications over time. In this paper, we studied the static and dynamic approaches and we made a comparison between different algorithms using several real datasets.","PeriodicalId":196827,"journal":{"name":"2016 4th IEEE International Colloquium on Information Science and Technology (CiSt)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115239076","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}

That's why we have been interested in studying the factors that influence this data quality. The first influencing factor is the quality of data at the source, and there are many other factors moderating this influence between data quality at the source and data quality at the data warehouse. This is what we have tried to gather in a research model in a previous work [1]. In order to validate this research model, we would like to conduct a survey and analyze the results using Structural Equation Modeling. And to prepare the survey, it is necessary to figure out the measured variables for each latent variable in the research model.

The interoperability of IS constitutes, their ability to communicate and to inter-operate following a given model using a common language favoring the sharing of information for better performance and profitability. [1] In this article we reminder of the model that we have proposed for the interoperability of IS, it is a model of interconnection having for objective the synchronization of the business process of IS interconnected. This synchronization is based mainly on the transformation of business processes BPMN (Business Process Model Notation) of the different IS in Executable Languages Business Process Execution Language (BPEL) thanks to a language ATL (ATLAS Transformation Language) then bring together all the BPEL in a single global BPEL to basis of the rules of adaptation and an ontological database. Then and using the reverse engineering, to make an update, well adapted, Process BPMN trades of different IS. The key point of this architecture is the use of the ontological database. We present in this article a new hybrid model of ontological database based on two approaches of schema of ontological storage different that we were able to create from the result of analysis of a comparative study of database systems to ontological basis (BDBO). This analysis has helped us to adopt a hybrid model of BDBO who owns his own architecture and its storage model.

However, due to the increasing number of vehicles and the high dynamic of the traffic network, conventional traffic signal timing methods does not result in an efficient control. One alternative is to let traffic signal controllers learn how to adjust the lights based on the traffic situation. In this paper, we propose a novel multi-objective traffic light control system that is based on an Intelligent Multi-Objective Particle Swarm Optimization (MOPSO) method. We take the average junction waiting time and the flow rate of vehicles on the congested road as two objectives. In the proposed method, we granted the ability of selecting appropriate MOPSO parameters to each agent of the swarm via a novel multi-objective Q-Learning approach. The simulation results demonstrate the efficiency of the proposed system.","PeriodicalId":196827,"journal":{"name":"2016 4th IEEE International Colloquium on Information Science and Technology (CiSt)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129080774","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}
