This paper discusses the knowledge interaction activities in the application and management stage of the industrial technology road-mapping, and analyzes the knowledge interaction scenario required for different knowledge interaction activities, including individual learning scenario, group face-to-face interaction scenario, group network interaction and collaboration scenario, industrial community disseminate scenario. On this basis, the industrial technology roadmap publishing platform is designed and developed. The platform has different functional modules, and each functional module provides technical and tool support for the knowledge interaction activities under the corresponding knowledge interaction scenario.
