Full textThe purpose of data mining is to extract knowledge from large amount of data. The extracted knowledge can take different forms. In this work, we will seek to extract knowledge only in the form of positive association rules and negative association rules. A negative association rule is a rule in which the presence and the absence of a variable can be used. When considering the absence of variables in the study, we will expand the semantics of knowledge and extract undetectable information by the positive association rules mining methods. This will, for example allow doctors to find characteristics that prevent disease instead of searching characteristics that cause a disease. Nevertheless, adding the negation will cause various challenges. Indeed, as the absence of a variable is usually more important than the presence of these same variables, the computational costs will increase exponentially and the risk to extract a prohibitive number of rules, which are mostly redundant and uninteresting, will also increase. In order to address these problems, our proposal, based on the famous Apriori algorithm, does not rely on frequent itemsets as other methods do. We define a new type of itemsets : the reasonably frequent itemsets which will improve the quality of the rules. We also rely on the M G measure to know which forms of rules should be mined but also to remove uninteresting rules. We also use meta-rules to allow us to infer the interest of a negative rule from a positive one. Moreover, our algorithm will extract a new type of negative rules that seems interesting : the rules for which the antecedent and the consequent are conjunctions of negative itemsets. Our study ends with a quantitative and qualitative comparison with other positive and negative association rules mining algorithms on various databases of the literature. Our software ARA (Association Rules Analyzer ) facilitates the qualitative analysis of the algorithms by allowing to compare intuitively the algorithms and to apply in post-process treatments various quality measures. Finally, our proposal improves the extraction in the number and the quality of the extracted rules but also in the rules search path

Full textThis thesis addresses the field of knowledge representation in conceptual graphs, a structured knowledge representation formalism that provides efficient manipulation tools. There are many challenges in symbolic artificial intelligence concerning the representation of knowledge in general, and in particular the concise representation of a large amount of information. Conceptual graphs, by their ability to visually represent different kinds of knowledge, mainly ontological and factual, and by offering efficient manipulation tools, provide a perfect framework for the answer to these problems. We conduct a comparative study of fuzzy extensions of conceptual graphs, then we propose an algorithm for conceptual graphs simulation as well as an efficient algorithm for extracting frequent patterns that are not redundant with ontological knowledge
