  • 21. Work in progress…  Split the screencast into scenes and compute similarities per scene.  Advanced identifier splitting techniques for filtering the video/audio data.  Deeper look on images/video processing to gain more information  Similarity measurement without removing duplicate words  Try to find link directly between screencasts and source code (by splitting identifiers)  Build a model for traceability links retrieval between screencasts and source code
