Full textThe thesis deals with the problem of knowledge transfer in mediated environments in the era of massive data. We propose a Multicriteria Approach for the Incremental Periodic Prediction (MAI2P) of the decision class to which an action is likely to belong. The MAI2P method is based on three phases. The first consists of three steps : the construction of a family of criteria for the characterization of actions ; the construction of a representative set of “Reference actions” for each of the decision classes ; and the construction of a decision table. The second phase is based on the DRSA-Incremental algorithm that we propose for the inference and the updating of the set of decision rules following the sequential increment of the “Reference actions” set. The third phase is meant to classify the “Potential Actions” in one of the predefined decision classes using the set of inferred decision rules. The MAI2P method is validated especially in the context of the Massive Open Online Courses (MOOCs), which are e-courses characterized by a huge amount of data exchanged between a massive number of learners. It allows the weekly prediction of the three decision classes : Cl1 of the “At risk learners”, those who intend to give up the MOOC; Cl2 of the “Struggling learners”, those who have pedagogical difficulties but have no plan to abandon it ; and Cl3 of the “Leader learners”, those who can support the other two classes of learners by providing them with all the information they need. The prediction is based on data from all the previous weeks of the MOOC in order to predict the learner profile for the following week. A recommender system KTI-MOOC (Recommender system for Knowledge Transfer Improvement within a MOOC) is developed to recommend to each “At risk learner” or “Struggling learner” a personalized list of “Leader learners”. This system is based on the demographic filtering technique and aims to promote the individual appropriation, of the exchanged information, for each learner

Full textIn graded multi-label classification (GMLC), each instance is associated to a set of labels with graded membership degrees. For example, the same odorous molecule may be associated to a strong 'musky' odor, a moderate 'animal' odor, and a weak 'grassy' odor. The goal is to learn a model to predict the graded set of labels associated to an instance from its descriptive variables. For example, predict the graduated set of odors from the molecular weight, the number of double bonds, and the structure of the molecule. Another interesting area of the GMLC is recommendation systems. In fact, users' assessments of items (products, services, books, films, etc.) are first collected in the form of GML data (using the one-to-five star rating). These data are then used to recommend to each user items that are most likely to interest him. In this thesis, an in-depth theoretical study of the GMLC allows to highlight the limits of existing approaches, and to introduce a set of new approaches bringing improvements evaluated experimentally on real data. The main point of the new proposed approaches is the exploitation of relations between labels. For example, a molecule with a strong 'musky' odor often has a weak or moderate 'animal' odor. This thesis also proposes new approaches adapted to the case of odorous molecules and to the case of large volumes of data collected in the context of recommendation systems

Full textThe works on web services management use generally the techniques of information retrieval, data mining and the linguistic analysis. Alternately, we attend the emergence of the probabilistic topic models originally developed and utilized for topics extraction and documents modeling. The contribution of this thesis meets the topics modeling and the web services management. The principal objective of this thesis is to study and propose probabilistic algorithms to model the thematic structure of web services. First, we consider an unsupervised approach to meet different tasks such as web services clustering and discovery. Then we combine the topics modeling with the formal concept analysis to propose a novel method for web services hierarchical clustering. This method allows a novel interactive discovery approach based on the specialization and generalization operators of retrieved results. Finally, we propose a semi-supervised method for automatic web service annotation (automatic tagging). We concretized our proposals by developing an on-line web services search engine called WS-Portal where we incorporate our research works to facilitate web service discovery task. Our WS-Portal contains 7063 providers, 115 sub-classes of category and 22236 web services crawled from the Internet. In WS- Portal, several technologies, i.e., web services clustering, tags recommendation, services rating and monitoring are employed to improve the effectiveness of web services discovery. We also integrate various parameters such as availability and reputation of web services and more generally the quality of service to improve their ranking and therefore the relevance of the search result

Full textThis thesis deals with the field of information retrieval and the recommendation of reading. It has for objects:— The creation of new approach of document retrieval and recommendation using techniques of combination of results, aggregation of social data and reformulation of queries;— The creation of an approach of recommendation using methods of information retrieval and graph theories.Two collections of documents were used. First one is a collection which is provided by CLEF (Social Book Search - SBS) and the second from the platforms of electronic sources in Humanities and Social Sciences OpenEdition.org (Revues.org). The modelling of the documents of every collection is based on two types of relations:— For the first collection (SBS), documents are connected with similarity calculated by Amazon which is based on several factors (purchases of the users, the comments, the votes, products bought together, etc.);— For the second collection (OpenEdition), documents are connected with relations of citations, extracted from bibliographical references.We show that the proposed approaches bring in most of the cases gain in the performances of research and recommendation. The manuscript is structured in two parts. The first part "state of the art" includes a general introduction, a state of the art of informationretrieval and recommender systems. The second part "contributions" includes a chapter on the detection of reviews of books in Revues.org; a chapter on the methods of IR used on complex queries written in natural language and last chapter which handles the proposed approach of recommendation which is based on graph

Full textThis thesis focuses on developing scalable algorithms for large scale machine learning. In this work, we present two perspectives to handle large data. First, we consider the problem of large-scale multiclass classification. We introduce the task of multiclass classification and the challenge of classifying with a large number of classes. To alleviate these challenges, we propose an algorithm which reduces the original multiclass problem to an equivalent binary one. Based on this reduction technique, we introduce a scalable method to tackle the multiclass classification problem for very large number of classes and perform detailed theoretical and empirical analyses.In the second part, we discuss the problem of distributed machine learning. In this domain, we introduce an asynchronous framework for performing distributed optimization. We present application of the proposed asynchronous framework on two popular domains: matrix factorization for large-scale recommender systems and large-scale binary classification. In the case of matrix factorization, we perform Stochastic Gradient Descent (SGD) in an asynchronous distributed manner. Whereas, in the case of large-scale binary classification we use a variant of SGD which uses variance reduction technique, SVRG as our optimization algorithm

Full textRecommender systems (RS) exploit users' behaviour to recommend to them items they would appreciate. Users Behavioral divergence on the web results in a problem of performance fluctuations to (RS). This problem is observed in the approach of collaborative filtering (CF), which exploites the ratings attributed by users to items, and in the trust-based approach (TRS), which exploites the trust relations between the users. We propose a hybrid approach that increases the number of users receiving recommendation, without significant loss of accuracy. Thereafter, we identify several behavioral characteristics that define a user profile. Then we classify users according to their common behavior, and observe the performance of the approaches by class. Thereafter, we focus on the TRS. The concept of trust has been discussed in several disciplines. There is no real consensus on its definition. However, all agree on its positive effect. Subjective logic (LS) provides a flexible platform for modeling trust. We use it to propose and compare three trust models, which aims to predict whether a user source can trust a target user. Trust may be based on the personal experience of the source (local model), or on a system of mouth (collective model), or the reputation of the target (global model). We compare these three models in terms of accuracy, complexity, and robustness against malicious attacks
