    Hidden Markov Models (HMM) are currently widely used in Automatic Speech Recognition (ASR) as being the most effective models. Yet, they sometimes pose some problems of discrimination. The hybridization of Artificial Neural Networks(ANN) in particular Multi Layer Perceptrons (MLP) with HMM is a promising technique to overcome these limitations. In order to ameliorate results of recognition system, we use Support Vector Machines (SVM) witch characterized by a high predictive power and discrimination. The incorporation of SVM with HMM brings into existence of the new system of ASR. So,

    by using 2800 occurrences of Arabic phonemes, this work arises a comparative study of our acknowledgment system of it as the following: The use of especially the HMM standards lead to a recognition rate of 66.98%. Also, with the hybrid system MLP/HMM we succeed in achieving the value of 73.78%. Moreover, our proposed system SVM/HMM realizes the best performances, whereby, we achieve 75.8% as a recognition frequency.

NLDB 2016 - 21st International Conference on Applications of Natural Language to Information Systems, juin, 2016, International Conference, Royaume-Uni
    The work presented in this paper aims at developing a Personalized Information Retrieval system in Arabic Texts (“PIRAT”) based on the user's preferences/interests. For this reason, we proposed a user’s modeling and a personalized matching method document-query. The proposed user’s modeling is based on a hybrid representation of the user profile. In this approach, we introduce an algorithm which automatically builds a hierarchical user profile that represents his implicit personal interests and domain. It is to represent the interests and the domain with a conceptual network of nodes linked together through relationships respecting the linking topology defined in the domain of hierarchies and ontologies (hyperonymy, hyponymy, and synonymy). Then, we address the problem of unavailable language resources by building i) a large Arabic text corpus entitled “WCAT” (ie 30550 articles) and ii) i) Building our own Arabic queries corpus entitled “AQC2” in order to evaluate the suggested PIRAT system and AXON system. The results of this evaluation are promising.

Towards an Interaction Protocols Adaptation and Management System for Coordination in Crisis Business Processes. 10th International KES Conference on AGENTS AND MULTI-AGENT SYSTEMS: TECHNOLOGIES AND APPLICATIONS KES-AMSTA-16, juin, 2016, Tenerife, Espagne

    This work addresses the Interaction Protocols (IP) adaptation issue for coordination in the context of Crisis Management Processes (CMP). CMP refers to the coordination of different activities performed by involved actors in a dy-namic and unstable context. Using interaction protocols (such as contract net, negotiation or vote) is one possible way to deal with this coordination. In order to guarantee an efficient use of IP, we need to adapt them. In our previous work, we proposed an MDA (Model Driven Architecture) framework to support the IP adaptation. More precisely, we proposed the conjointly use of version and context notions to model the IP versions and their contexts (the CIM level). We also pro-posed an extension of AUML sequence diagram meta-model to specify graph-ically the contextualized versioned interaction protocols (the PIM level). In this paper, we propose an Interaction Protocols Adaptation and Management System (IPAMS) that supports the previous contributions. This IPAMS ensures the IP adaptation at run time. Finally, we propose a well-known crisis scenario called “Air Crash Management Process” in order to illustrate the proposed solution.

    Process flexibility has been investigated in depth in
    the context of intra-organisational processes, but it is still an open
    issue when processes cross the boundaries of companies. In this
    paper, we address the modelling of flexible inter-organisational
    processes using a version-based approach. Indeed, versions are
    known to be a powerful technique to deal with variability,
    evolution and adaptation of processes, which are the three main
    needs of process flexibility. More precisely, this paper presents
    VP2M (Version of Process Meta-Model), a meta-model
    supporting the modelling of versions of inter-organisational
    processes, addressing both static and dynamic aspects of VP2M.
    It also illustrates process version modelling within the Subsea
    Pipeline process example.

The 14th International Conference on Software Engineering Research, Management and Applications (SERA), juin, 2016, Towson, Etats-Unis
    Abstract—Dealing with unstructured information is currently a hot research topic since most documents exist in an unstructured form. The effective exploitation of unstructured document, although intricate, is of paramount importance to Information Retrieval (IR). The key to using unstructured data set is to identify the hidden structures within the data set. In this paper, we present an approach to recognize the semantic structure of documents in Arabic legal data. Several main concepts of a document are expressed in this structure, which includes title, the headings of the chapters, sections, subsections, etc.
    This structural information is employed to obtain a richer and more fine-grained annotation of documents forming a useful and coherent infrastructure ready for IR. Some experiments were conducted in order to evaluate our approach. The initial results seem promising.
    Keywords—document ontology, document structure extraction, document annotation, legal information retrieval

    Abstract: Improving retrieval systems performance involves discovering more relevant answers and at the same time reducing the number of non-relevant ones that will be retrieved. Providing advanced query functionalities can serve as support to the improvement. In the legal domain, known by its complexity, advanced querying requires on beyond a rich annotation of documents that takes into account their semantic content as well as their structure. The proposed approach demonstrates that the use of NLP techniques and tools in conjunction with a domain ontology that automate the process of information extraction from legal texts through a meaningful annotation is of paramount importance to provide a better access to Arabic legal information.

    Keywords: Legal documents annotation, Document’s structure, Document’s semantic content, domain ontology.

Abstract The Bayesian Networks are graphical models that are easy to interpret and update. These models are useful if the knowledge is uncertain, but they lack some means to express ambiguity. To face this problem, we propose Fuzzy Evidence in Bayesian Networks and combine the Fuzzy Logic and Bayesian Network. This has allowed to benefit from mutual advantages of these two approaches, and to overcome the problem of data and observation ambiguity. This paper proposes an inference algorithm which uses the Bayesian Network and Fuzzy Logic reliability. This solution has been implemented, tested and evaluated in comparison with the existing methods.
