Abstract
A method, system and computer-usable medium are disclosed for preserving temporal relevance in a response to a query. A query is processed to extract first temporal features, which is then used to identify first documents within a corpus. The first documents are processed to generate first metadata and mined content, which is processed with the first temporal features to generate second documents having second temporal features corresponding to the first temporal features. The corpus is updated with new documents and revisions to the first documents to generate second documents. In turn, the second documents are processed to generate second metadata and mined content, which is then used to generate a ranked list of temporally-relevant documents.
