Detective Brooklynk is an information retrieval system to provide a list of possible web pages to substitute the one pointed by a broken link. The system uses natural language techniques, such as named entity recognition, information extraction techniques and language models to extract information related to the considered broken link. This information is then used to make several queries, which are submitted to different search engines to retrieve documents related to the missing web page. In order to tune the results, the pages recovered in this way are ranked according to relevance measures obtained by applying information retrieval (IR) techniques, and finally this ordered list of results is presented to the user.
