BM25-CTF: Improving TF and IDF factors in BM25 by using collection term frequencies
In this paper, the use of collection term frequencies (ie the total number of occurrences of a
term in a document collection) in the BM25 retrieval model is investigated by modifying its …

Exploring the space of information retrieval term scoring functions
In this paper we are interested in finding good IR scoring functions by exploring the space of
all possible IR functions. Earlier approaches to do so however only explore a small sub-part …
