The Idea Automated Author Disambiguation Open for all kinds of data sets. Mine authors on papers for... eMail, affiliations and Co-authorship similarity Design Program which is easily expandable 6

Increasing Intelligence Adding data sources to the algorithm Make use of existing disambiguated sets Web 2.0 functions - let the community help! “Claim My Paper” - Authors identify their papers online “Tagging” - Authors spend some spare time to tag articles Human expert intelligence in special cases 7

What’s next? Author disambiguation will enable many services Detailed author information More useful citation data Automated creation of publication lists or academic biographies Ranking of authors... 8

Author Ranking Bypass the Impact Factor Analysis of co-authorship and citation networks Contextual citations Search patterns/click streams of users Many more... 9

The Algorithm 1. Extract information 2. Cluster extracted information 3. Process Clusters and find potential real authors 4a. Assign ID to certain cases 4b. Send undecidable cases to human helpers. 4c. Use gained information to reprocess other real authors. 11
