El, Baida Rania. „Gestion des incohérences dans les systèmes de contrôle d'accès“. Artois, 2004. http://www.theses.fr/2004ARTO0401.
Der volle Inhalt der QuelleModelling information security policies is being an important task in many domains. We proposed a new access control system called OrBAC (Organization based access control). This system brings many solutions to the existing access control systems. For instance, OrBAC takes into account the context and is able to represent various kinds of privileges : permission, prohibition and obligation. However, this system does not deal with conflicts due to the joint handling of permission or obligation and prohibition policies. We dealt with the problem of handling conflicts in the OrBAC system, modelled by first order logic knowledge bases. We showed that approaches suggested for handling conflicts in propositionnal knowledge bases are not adapted for inconsistent first order knowledge bases. We proposed an approach in which we weak first order formulas responsible of conflicts
Bourgaux, Camille. „Gestion des incohérences pour l'accès aux données en présence d'ontologies“. Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLS292/document.
Der volle Inhalt der QuelleThe problem of querying description logic knowledge bases using database-style queries (in particular, conjunctive queries) has been a major focus of recent description logic research. An important issue that arises in this context is how to handle the case in which the data is inconsistent with the ontology. Indeed, since in classical logic an inconsistent logical theory implies every formula, inconsistency-tolerant semantics are needed to obtain meaningful answers. This thesis aims to develop methods for dealing with inconsistent description logic knowledge bases using three natural semantics (AR, IAR, and brave) previously proposed in the literature and that rely on the notion of a repair, which is an inclusion-maximal subset of the data consistent with the ontology. In our framework, these three semantics are used conjointly to identify answers with different levels of confidence. In addition to developing efficient algorithms for query answering over inconsistent DL-Lite knowledge bases, we address three problems that should support the adoption of this framework: (i) query result explanation, to help the user to understand why a given answer was (not) obtained under one of the three semantics, (ii) query-driven repairing, to exploit user feedback about errors or omissions in the query results to improve the data quality, and (iii) preferred repair semantics, to take into account the reliability of the data. For each of these three topics, we developed a formal framework, analyzed the complexity of the relevant reasoning problems, and proposed and implemented algorithms, which we empirically studied over an inconsistent DL-Lite benchmark we built. Our results indicate that even if the problems related to dealing with inconsistent DL-Lite knowledge bases are theoretically hard, they can often be solved efficiently in practice by using tractable approximations and features of modern SAT solvers

Der volle Inhalt der QuelleWe investigate the feasibility of automated reasoning over temporal DL-Lite (TDL-Lite) knowledge bases (KBs). We translate TDL-Lite KBs into a fragment of FO-logic and into LTL and apply off-the-shelf LTL and FO-based reasoners for checking the satisfiability. We conduct various experiments to analyse the runtime performance of different reasoners on toy scenarios and on randomly generated TDL-Lite KBs as well as the size of the LTL translation. To improve the reasoning performance when dealing with large ABoxes, our work also proposes an approach for abstracting temporal assertions in KBs. We run several experiments with this approach to assess the effectiveness of the technique by measuring the gain in terms of the size of the translation, the number of ABox assertions and individuals. We also measure the new runtime of some solvers on such abstracted KBs. Lastly, in an effort to make the usage of TDL-Lite KBs a reality, we present a fully-fledged tool with a graphical interface to design them. Our interface is based on conceptual modeling principles, and it is integrated with our translation tool and a temporal reasoner. In this thesis, we also address the problem of handling inconsistent data in Temporal Description Logic (TDL) knowledge bases. Considering the data part of the knowledge base as the source of inconsistency over time, we propose an ABox repair approach. This is the first work handling the repair in TDL Knowledge bases. To do so, our goal is two folds: 1) detect temporal inconsistencies and 2) propose a data temporal repair. For the inconsistency detection, we propose a reduction approach from TDL to DL which allows to provide a tight NP-complete upper bound for TDL concept satisfiability and to use highly optimized DL reasoners that can bring precise explanation (the set of inconsistent data assertions). Thereafter, from the obtained explanation, we propose a method for automatically computing the best repair in the temporal setting based on the allowed rigid predicates and the time order of assertions

Der volle Inhalt der QuelleIn this thesis, we have studied logical and graphical models for the management of incoherent and uncertain information. In the first part, we have studied an extension of lightweight ontologies, encoded here in DL-Lite languages, for the product-based possibility theory framework. We first have introduced the language and the semantics used for representing uncertainty in lightweight ontologies. Then, we have shown that contrarily to a min-based possibilistic DL-Lite, query answering in a product-based possibility theory is a hard task. When the uncertainty is only considered at the ABox level, we have provided equivalent transformations between the inconsistency degree computation problem (the key notion in reasoning from a possibilistic DL-Lite knowledge base) and the weighted maximum 2-Horn SAT problem. In the general case, where the TBox may also be uncertain, we have modeled the inconsistency degree computation as an integer linear programming problem. Moreover, we have provided in both cases, an encoding of the problem of computing inconsistency degree in product-based possibility DL-Lite as a weighted set cover problem and we have used a greedy algorithm to compute an approximate value of the inconsistency degree. This encoding allows us to provide an approximate algorithm for answering instance checking queries in product-based possibilistic DL-Lite. Lastly, we have presented an experimental study where the different proposed solutions are compared. We have shown in particular the efficiency of the integer linear programming approach compared with the two other solutions based on the weighted Max-2-Horn-SAT and the approximate greedy algorithm. In the second part of the thesis, we have implemented the problem of decision-making. We have implemented and, improved a new version of the possibilistic influence diagram decomposition process into two possibilistic networks without reduction, reducing the complexity of the resulting networks and thus improving the computation of the optimistic decision-making process. In addition, we have proposed an approximate approach for the computation of decision under uncertainty within possibilistic networks. The computing of the optimal optimistic decision no longer goes through the junction tree construction step. Instead, it is performed by calculating the degree of normalization in the moral graph resulting from the merging of the possibilistic network codifying knowledge of the agent and that codifying its preferences
Pham, Phuong Thao. „Architecture à base de situations pour le traitement des quiproquos dans l'exécution adaptative d'applications interactives“. Thesis, La Rochelle, 2013. http://www.theses.fr/2013LAROS415/document.
Der volle Inhalt der QuelleOur works focus on defining an architectural model for interactivity-based computer applications. The research context is placed in the mediator systems where the interactions are treated by the system itself, and in the scenarized applications where its execution is considered as a scenario. This aims to manage at best the interactive application execution. The observation and adaptation are key points of our approach where the designer develops his interactive application according to the presuppositions about users (behaviour, skills...). To maintain an execution consistence towards user’s behaviour in current activities, the adaptation mechanism has to take into account the perceived and interpreted user’s logic. That allows the system to adjust its execution logic to user’s state, behaviour, reactions and capacities. Hence, the starting point of adaptive execution is to define a set of proprieties characterising user’s state and his environment of which the observation permits thereafter to make decisions about the future scenario continuity. However, this decision can be influenced or hampered by the difference distance between the observed state and the real state of user, also the distance between the observed state and the expected one by the system. The principal obstacles against the adaptation and interactions are : the ambiguity, the inconsistency, and the misunderstanding. They can occur when the participant actors interact, share global data, and manage the local knowledge contained in their local visions at the same time. A misunderstanding in interaction arises during actors’ interactions using the inconsistent data in their local visions that can impact badly on interaction. The ambiguity causing possibly the wrong perceptions is one of the principal misunderstanding origines. Theses obstacles lead to serious consequences for the system and application such as scenario deviation, misunderstanding propagation, interaction interruption, user’s motivation lost...They decrease the adaptation quality and interaction pertinence. Hence, the principal question of this thesis is : how can we handle the misunderstanding in interactions between the actors during system execution in order to improve adaptability in the interactive applications ? Our solution principle is to propose a model for interaction designing and organizing, together with a model for consistency handling mechanisms that application designers can employ as a necessary support to install his own detection or correction algorithms. These models have to be generic, reusable to be applied in different types of application. The consistency managements have to be transparent to users, and preserve important properties of interactive systems. To attain this objective, our works follow three major points : propose a situation-based methodological model for interactive application designing to confine a sequence of interactions into a situation with the constraints of context and resource utilisation. This structuration into situations propose a robust system architecture with additional specific components that ensure misunderstanding in interaction detection and management. Integrate the adaptive treatment mechanisms to the dynamic system’s execution through the proposed situation-based architectural model. They are inspired and adapted from fault-tolerance techniques in dependability domain
