This is an achievement nearly five months old, but SIEL has shared the news about it internally only recently.

IIIT-H's Search and Information Extraction Lab (SIEL) was ranked No.1 at CLEF-IP 2011. The international competition, conducted annually by the Cross Language Evaluation Forum (CLEF), involves retrieving digitally stored patents in other languages that are similar to a given patent. Technically, such tasks are termed Cross Language Patent Retrieval.

CLEF is a well known European organization focused on investigating and evaluating information retrieval (IR) techniques.


Manisha Verma, an MS by Research student at SIEL, was the main contributor to winning the contest, under the guidance of Prof. Vasudeva Varma, the head of SIEL.
