Standard entity clustering systems commonly rely on mention (string) matching, syntactic features, and linguistic resources like English WordNet. When co-referent text mentions ap- pear in different languages, these techniques cannot be easily applied. Consequently, we develop new methods for clustering text men- tions across documents and languages simulta- neously, producing cross-lingual entity clusters. Our approach extends standard clustering algo- rithms with cross-lingual mention and context similarity measures. Crucially, we do not as- sume a pre-existing entity list (knowledge base), so entity characteristics are unknown. On an Arabic-English corpus that contains seven dif- ferent text genres, our best model yields a 24.3% F1 gain over the baseline.
