Study on Knowledge Reuse Based on Knowledge Scenario

This paper studies on knowledge reuse means and technology based on knowledge scenario. Knowledge scenario is the concrete background and environment of knowledge production and application. This study models knowledge scenario using scenario tree and gets the similarities of knowledge nodes through matching ontology concepts. Node weight is introduced to calculate the similarities of scenario tree for knowledge reuse. The concepts of similarity vector and patch scenario are proposed for searching similar scenario. The patch scenario is attained through analyzing the similarity vector, and a knowledge innovation mechanism is constructed to integrate the knowledge of the similar scenario and its patch scenario. A knowledge reuse management framework based on knowledge scenario is established, which comprises of query model producing, scenario base , knowledge base and scenario patch and analysis, for realizing the management of knowledge reuse and renovation. Finally, an application instance for commodity sales promotion is analyzed to explain the process of knowledge reuse based on knowledge scenario.
