Given that users are often concerned with the need to filter a large amount of data to better satisfy their requirements and needs, and that data analysis can be based on inaccurate, incomplete, ambiguous, duplicated and of poor quality, it makes everyone wonder what the results of these analyses will really be like. However, there is a very complex process involved in the identification of new, valid, potentially useful and meaningful data from a large data collection and various information systems, and is critically dependent on a number of measures to be developed to ensure data quality. To this end, the main objective of this paper is to introduce a general study on data quality related with big data, by providing what other researchers came up with on that subject. The paper will be finalized by a comparative study between the different existing data quality models. {\textcopyright} 2020 ACM.}, keywords = {Big data, Comparative studies, Complex Processes, data quality, Data quality assessment, Data quality models, Data reduction, Data-sources, Intelligent systems, Large amounts, Large data}, doi = {10.1145/3419604.3419803}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85096426287\&doi=10.1145\%2f3419604.3419803\&partnerID=40\&md5=7542ef0e44f4d94b808c64ce466a5eca}, author = {Reda, O. and Sassi, I. and Zellou, A. and Anter, S.} } @conference {Anter2016, title = {Nk-schemas: A novel algorithm for creating the view{\textquoteright} schemas to materialize in hybrid mediator}, booktitle = {Proceedings of IEEE/ACS International Conference on Computer Systems and Applications, AICCSA}, volume = {2016-July}, year = {2016}, note = {cited By 0}, abstract = {The explosion of information and telecommunications technologies, has made easy the access and production of information.

Thus, and in order to manage this diversity of information, the integration systems were proposed. Among these, we find the hybrid information integration systems. They allow materializing a part of data in a local database, while integrating virtually the other part. As these materialized one is organized as views, it becomes necessary to propose algorithms for this objective. Among the most interesting ones, there is k-schema. It allows organize the attributes into a set of views, while affecting an attribute to a single view. This choice causes the not loading some of data that are highly requested by users, and at the same time, it loads other that are rarely requested. In this paper, we propose a new algorithm in this end. In this latter, it is authorized to assign a same attribute to several views. We also proposed new functions for calculating the dependencies between attributes. {\textcopyright} Research India Publications.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84973470278\&partnerID=40\&md5=140f0f35ca53260f11d97b5958f6ee8c}, author = {Anter, S. and Zellou, A. and Idri, A.} } @conference {Anter2016, title = {Towards a generic model of a user profile}, booktitle = {SITA 2016 - 11th International Conference on Intelligent Systems: Theories and Applications}, year = {2016}, note = {cited By 0}, abstract = {User modelling is an old research discipline. The main concern of this discipline is to improve the quality of human-computer interaction predictive goals, preferences and context. Thus, adaptation and personalization of a document or an application for a particular user need to have information on the latter. It often referred to as {\textquoteright}user profile{\textquoteright}. A user profile modelling process must be done in two stages. These can be expressed by two questions: (1) {\textquoteright}what data?{\textquoteright} and (2) {\textquoteright}In what form will they be organized?{\textquoteright} The answer to the first question will determine all relevant information that best represents the interests and needs of the user. As for the second, it will determine the logical structure in which a profile will be modelled. This paper aims to provide answers to both questions. To do this, we begin with a presentation of different areas where the user profile can make a major contribution. In the second step, we define all the information to be included in the user profile as well as a generic model that we can adapt to different areas. {\textcopyright} 2016 IEEE.}, doi = {10.1109/SITA.2016.7772265}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85010301085\&doi=10.1109\%2fSITA.2016.7772265\&partnerID=40\&md5=2f2efa11599627d6b4c5ad967869851f}, author = {Anter, S. and Yazidi, M.H.E. and Zellou, A. and Idri, A.} } @conference {Anter2015, title = {Nk-schemas: A novel algorithm for creating the views{\textquoteright} sch{\'e}mas to materialize in hybrid mediator}, booktitle = {Proceedings of 2015 IEEE World Conference on Complex Systems, WCCS 2015}, year = {2015}, note = {cited By 0}, abstract = {The explosion of information and telecommunications technologies, has made easy the access and production of information.

This information is generally heterogeneous, stored in autonomous and distributed sources. Thus, it becomes necessary to introduce the information integration systems. These systems must ensure an optimal query response time, and the freshness of data. Using a virtual approach cannot answer these questions. On the one hand, the query response time is very important. Indeed, the mediator must access, every time, to the sources for load the relevant information. On the other hand, the sources are not always available. The establishment of a hybrid integration system, where a portion of information is materialized in the mediator and the other portion remains in the sources and are extracted at query time, is an effective solution to these problem, provided that the materialized part has carefully chosen. Based on the distribution of user queries, we present in this paper an approach to select the information most requested by users and organize it as candidate views for materialization in the mediator. {\textcopyright} 2013 IEEE.}, doi = {10.1109/CSIT.2013.6588780}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84884866157\&doi=10.1109\%2fCSIT.2013.6588780\&partnerID=40\&md5=901ef3c27b658be16f920570e0dd9cce}, author = {Anter, S. and Zellou, A. and Idri, A.} } @article {Anter2013158, title = {K-Schema: A new approach, based on the distribution of user queries, to create views to materialize in a hybrid integration system}, journal = {Journal of Theoretical and Applied Information Technology}, volume = {47}, number = {1}, year = {2013}, note = {cited By 2}, pages = {158-170}, abstract = {The explosion of information technologies and telecommunications has made easy the access and production of information.

Among the latter, there are the hybrid integration systems. These offer a local database where it stores a part of data while integrating the other part virtually. This in the objective to increases system performance while ensuring a tradeoff between query response time and data freshness. The approach that has proposed a complete solution is one that creates the candidate views for materialization before selecting among them those that will be materialized. To do this, it selects the attributes most requested by users. Calling the algorithm k-schema, these attributes are organized in schemas, on which we based to build the candidate views for materialization. This approach suffers from a defect. It is because in the phase of the extraction of attributes of interest, we based only on their frequencies of appearance in the user queries. This will select some attributes, even if they do not respond to any selection criterion. Thus, they cause the elimination, in the selection phase, of views to which they were assigned. In this paper, we propose a new approach, which eliminates all attributes that do not respond to the selection criteria prior to the creation of views to materialize. We also propose a new solution to calculate the values of attributes relative to different criteria. {\textcopyright} 2013 Praise Worthy Prize S.r.l. - All rights reserved.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84881501064\&partnerID=40\&md5=5b529bb907d58895a51faec2468f9a6c}, author = {Anter, S. and Zellou, A. and Idri, A.} } @conference {Anter2012, title = {Personalization of a hybrid integration system: Creation of views to materialize based on the distribution of user queries}, booktitle = {Proceedings of 2012 International Conference on Complex Systems, ICCS 2012}, year = {2012}, note = {cited By 0}, doi = {10.1109/ICoCS.2012.6458566}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84874493599\&doi=10.1109\%2fICoCS.2012.6458566\&partnerID=40\&md5=8cb54118f3a51aadd4afa9789ecdcc3a}, author = {Anter, S. and Zellou, A. and Idri, A.} }
