Context and Learning in Novelty Detection

  title={Context and Learning in Novelty Detection},
  author={Barry Schiffman and Kathleen McKeown},
We demonstrate the value of using context in a new-information detection system that achieved the highest precision scores at the Text Retrieval Conference’s Novelty Track in 2004. In order to determine whether information within a sentence has been seen in material read previously, our system integrates information about the context of the sentence with novel words and named entities within the sentence, and uses a specialized learning algorithm to tune the system parameters.
