This paper addresses the increasingly encountered challenge of knowledge indexation. In the past decade, research on numerical schemes on knowledge indexation has been quite intensive. Vector space model is only based on the information contained in term weighting and does therefore not process the semantic contained in the sequence in which the words(More)
Numerical schemes research on clustering model has been quite intensive in the past decade. The difficulties associated with curse of dimensionality and cost functions to reflect the general knowledge about internal structures and distributions of target data. Traditional computational clustering and variables selection schemes are struggling to estimate at(More)
The integration of knowledge can be considered as a guideline for managing problems that occur in the task of knowledge management, and more particularly, in the collaborative decision-making. Integration is necessary because it allows communication between different sources. Most of the proposed approaches provide limited support for all activities of the(More)
In recent years, clustering has become a critical success factor for data analysis. Most clustering methods are sensitive to outliers, noise, presentation order, configuration architecture, Bellman's curse of dimensionality and complex shapes. They use the cost functions to reflect the general knowledge about internal structures and distributions of target(More)
