With the globalization process, companies are increasingly decentralized, which makes it a challenge to exchange knowledge between employees. In literature, several Knowledge Management practices aims at facilitating the knowledge exchange, but many of them have difficulties in collecting and later reuse that knowledge. Some of these practices are based on the employee experience exchange, through sharing stories. The objective of this Thesis is define a model for the representation of stories (ontology), a set of activities, rules and tools to improve the collective dynamic gathering and the reuse of knowledge. Through some experiments we observed that this proposed model is better than other models regarding the collection and reuse of knowledge.
