Probabilistic Datalog and tolog

The TMRA05 presentation of a TM application framework by Naito-san made me mention "probabilistic datalog" because I think this might be relevant to fuzzy Topic Maps retrieval with tolog-like languages.

Lars Marius Garshol blogged my remark right away:
"In the questions Alex Sigel brought up something I think was called "probabilistic Datalog", which is used in information retrieval. That sounded quite relevant, and interesting. I may need to do some digging on that. "

A decade ago, Prof. Norbert Fuhr had extended Datalog to Probabilistic Datalog.
In turn it had been extended for usage with DAML+OIL, OWL's predecessor.

Here some references:
For implementing the logical model of databases, a variant of Horn logic called Datalogis widely used. Regarding IR as generalization of database retrieval, it seems quite naturalto develop a probabilistic version of Datalog.

Thanks for these references, Alex! I've now printed a couple of the papers, and put them in my to-read pile. I like the fact that the probabilistic Datalog is used for information retrieval, the key usecase for Topic Maps.
