Ways to improve the relevance of a query based on user feedback.

For example:

1. User inputs query.
2. Show some documnets.
3. Ask which documents their interested.
4. Automatically reform query to better represent the relevant documents.
5. Show more documents.

This concept is represented mathematically [see page 9, here]. Using a vector representation we offset the document position in vector-space by a weighted average of irrelevent and relevant documents to skew the results and better represent the users target documents area.
