This is the description of the "applicant view" run from the BiTeM team

- number of created indexes, index languages
1 index created. Index is in English.

Terrier PL2 weigthing scheme with Terrier Bo1 Query expansion

- multilingual purposes
use of Google translator (from French or German to English) when a given field is not available in English in both collection and topics
For the collection, only 10% of the collection needs this multilingual strategy, that is not a lot for a multilingual task.

- postprocessing
use of citations of the retrieved documents
use of IPC codes for filtering results

In this run, we simulate a Prior Art Search for an applicant.
So, citations provided by the applicant in the description field are not used.
