Interfaces and Metadata... a well known Problem with existing solutions
Harald Sack, From Script Idea to TV Rerun, LIME 2015, Florence, Italy, May 18, 2015
Problems:● Valuable metadata gets lost between the departments● Costly reengineering & retrieval of previously available
(meta-)data● no common (Meta-)Data Formats● Proprietary Hard- and Software with heterogeneous
interfaces

Challenges for Media Distribution
Harald Sack, From Script Idea to TV Rerun, LIME 2015, Florence, Italy, May 18, 2015
● Deliver the media to the customer while the customer
should NOT worry about
○ media formats
○ media distribution channels
○ media modalities and restrictions
○ rights management issues
○ to find accurately what the customer is looking for
○ to find more of what is interesting for the
customer, but was not looked for intentionally...

Exploratory Searchbased on intelligent recommendations
Harald Sack, From Script Idea to TV Rerun, LIME 2015, Florence, Italy, May 18, 2015
Serendipity: ● find a solution to a problem, which is relevant, but that you did not look for
intentionally ● a search result is a „serendipitious finding“, if it is interesting and
positively surprising at the same time.● surprising ≈ unexpected (statistically)
Relevance:● in general: adopted from Information Retrieval,● e.g. Popularity (PageRank), Specificity(TF-IDF, BM25), ranking heuristics● the actual relevance (importance) of a fact is determined by the personal
context and the Intention (Pragmatics) of the user.
