PERCOP represents a generic approach that improves the information search and retrieval process during different software-intensive activities with the use of context information. One main goal is the integration of the “crowd” at different stages of this process by combining collective intelligence concepts with context-aware systems. This combination can be used to automatically reduce information overflow by filtering irrelevant data. Furthermore, a real-time information retrieval process without manual search impulses is provided.


Systems, application functionality, concepts, frameworks and technical systems are changing and increasing in short intervals. Due to this fact obtaining relevant information for a specific issue is a frequently executed and time-consuming process. One corresponding problem is that the availability of nearly unlimited amount of data results in overflow. A major problem is the efficiency of information search and retrieval processes. Studies predicted that employees spent a large amount of time in searching for information. Another problem is the fact that a great number of people have suboptimal strategies while using web search engines in order to find relevant information.
