AckSeer is a beta automatic acknowledgment indexing search engine that explores automatic identification, entity extraction and indexing of acknowledgements from papers. In addition acknowledged entities are extracted within the acknowledgment passages.
Currently, AckSeer indexes acknowledgments from more than 500,000 papers in CiteSeerX. These acknowledgements contain more than 4 million acknowledged entities with approximately 2 million of them unique. Entity extraction is based on AlchemyAPI and OpenCalais. Acknowledged entities are ranked by citation. Feedback is most welcomed. http://ackseer.ist.psu.edu
