Résumé:
Knowledge is power. Each organization try to manage their knowledge as much as possible to
use it in order to determine and achieve their objectives. The knowledge acquisition is one of the most
important process in Knowledge Management. It allows to acquire crucial tacit and explic it
organizational knowledge within the company. The objective of this process is to acquire knowledge
from knowledge holders such as domain experts, employees, managers... and from heterogenous
explicit knowledges sources such documents, databases…. The main goal of our work which is
proposed in this thesis is the definition of the Knowledge Acquisition process and discuss the impact
of Cloud Computing paradigm to achieve the process within an organization. The proposed approach
is mainly based on knowledge engineering and Cloud Computing. We developed a Knowledge
Acquisition System for tacit and explicit knowledge acquisition. Tacit knowledge Acquisition is
based on existing Tacit Knowledge Acquisition methods and knowledge modeling. Explic it
Knowledge Acquisition is based on the Knowledge Discovery form Data process and Data Mining
technics as we focus on knowledge embedded in operational databases. We validate the proposed
system through a case study.
Key words: Knowledge Management, Knowledge Models, Knowledge Acquisition Process,
Knowledge Engineering, Data Mining, Cloud Computing.
