This is a review of the paper Cohen_2000_whirl_a_word_based_information_representation_language by user:sgopal1.
This paper proposes a an algorithm, syntax and structure for retrieving information from structured data. It looks extremely similar to prolog, but uses difference inference mechanisms to retrieve the r-best-lists ( r-materialization ).
Key points

- Soft-matching between texts using TF-IDF or any other similarity metric.
- The database of facts along with scores, appropriately combines scores and presents it to the user
