We have a new tutorial on Okapi Simple BM25 with Extension to Multiple Fields.
http://www.miislita.com/information-retrieval-tutorial/okapi-simple-bm25f-tutorial.pdf
Unlike the BM25, this model (known as Simple BM25F) incorporates the structure of documents into the scoring process.
In addition, we’ve uploaded a new, improved, and expanded version of the Okapi Best Match 25 tutorial.

Hi, there:
Thank you for taking the time to stop by. The site http://www.miislita.com, where all those tutorials reside is under migration to a new home.
@egarcia: Thank you
Hello,
I’m also interested in information retrieval systems and would like to read these articles about BM25F but the link is still unavailable.
