Mechanisms for document processing and analysis can include receiving a document and identifying, in a data structure, a record corresponding to the document. The record can include one or more entries, where each entry contains data reflecting a respective item of information extracted from a corresponding part of the document. The mechanisms can include determining for each entry of the record, a corresponding degree of association between the entry and a respective item of information referenced by the entry. They can further include updating the corresponding degrees of association, and selecting, among the corresponding degrees of association, a set of corresponding degrees of association whose aggregate degree of association satisfies a criterion.
