On Top-k Retrieval for a Family of Non-monotonic Ranking Functions.

In Proceedings of the 10th International Conference on Flexible Query Answering Systems (FQAS-13).


Abstract:

We presented a top-k algorithm to retrieve tuples according to the order provided by a non-necessarily monotone ranking funtion that belongs to a novel family of functions, satisfying some conditions related to the values where the maximum score is achieved.
