Hi Henning,
Yeah, I got reviewers who want me to use BM25F since I cannot beat
BM25 with the other models that PF/Tijah offers.
I have an xquery that does some relevance boosting after the results
are returned, so I guess BM25F can be used by post-processing the
runs.
I was also wondering whether anyone tried pseudo-relevance feedback
with PF/Tijah?

hej Junte,
you mean you would like to use/test the BM25F retrieval model? If you set the option <TijahOptions ir-model="OKAPI"/> PF/Tijah uses the BM25 retrieval model. I cannot say at the moment if it is an implementation of BM25F. You need to ask Djoerd in that case, since he implemented the OKAPI retrieval model.

I was wondering whether it would be possible to use BM25F? http://trec.nist.gov/pubs/trec13/papers/microsoft-cambridge.web.hard.pdf
Anyone else tried this before with an XQuery?
