We describe clustering experiments for cross-document coreference for the first Web People Search Evaluation. In our ex- periments we apply agglomerative cluster- ing to group together documents potentially referring to the same individual. The algo- rithm is informed by the results of two dif- ferent summarization strategies and an off- the-shelf named entity recognition compo- nent. We present different configurations of the system and show the potential of the ap- plied techniques. We also present an analy- sis of the impact that semantic information and text summarization have in the cluster- ing process.
