A social network based collaborative video story composition platform

There is a large number of videos produced and stored in data repositories on a daily basis. Story-telling is a common use-case for using these videos where a user composes a set of videos together to tell a story, either for learning purposes or sharing experiences. For example, a news editor may search and compose story based on video collected from multiple private and public repositories; an instructor may produce teaching materials using a set of publicly available video clips. Existing search engines have limitation on identifying useful video contents for users with different needs [2]. For a user who attempts to compile a story using a variety of videos, there are a few challenges with existing technologies. A search engine often returns a long list of videos that are relevant to the keywords the user enters into the search engine. How the videos in the list are suitable for the story line requires the users further investigation and the amount of work involved often overwhelms the user considering the number of videos returned by a search engine. It is often the case that the highly ranked videos are not the most appropriate ones for a story line under composing. In addition, videos are not organized in a structured manner based on the content, which makes identifying videos that match the story topic difficult and time consuming
