Abstract	:	This dissertation presents original techniques for statistical fact extractionand fusion from multiple documents. Fact extraction, or relationship extraction,is a process where natural language text is scanned to find instances of a predeter-mined class of facts (e.g. birthday(x,y)). A framework for training statistical factextractors from example is used wherein a set of examples and a target model areused to annotate an automatically collected corpus. This annotation is then used t oprovide training data for classifiers (Phrase Conditional Likelihood and Nai've Bayes)or sequence models (Conditional Random Fields).Fact extractors are used in two information retrieval tasks.
