Text REtrieval Conference (TREC) 1992¶
Adhoc¶
The ad hoc task investigates the performance of systems that search a static set of documents using new topics. This task is similar to how a researcher might use a library — the collection is known but the questions likely to be asked are not known.

Routing¶
In TREC the routing task is represented by using known topics and known relevant documents for those topics, but new data for testing. The participants are given a set of known (or training) topics, along with a set of documents, including known relevant documents for those topics. The topics consist of natural language text describing a user's information need. The topics are used to create a set of queries (the actual input to the retrieval system) which are then used against the training documents.
