  • Patent number: 6167398
    Abstract: An internet information agent accepts a reference document, performs an analysis upon it in accordance with metrics defined by its analysis algorithm and obtains respective lists (word, character-level n-gram, word-level n-gram), derives weights corresponding to the metrics, applies the metrics to a candidate document and obtains respective returned values, applies the weights to the returned values and sums the results to obtain a Document Dissimilarity (DD) value. This DD is compared with a Dissimilarity Threshold (DT) and the candidate document is stored if the DD is less than the DT. A user can apply relevance values to the search results and the agent modifies the weights accordingly. The agent can be used to improve a language model for use in speech recognition applications and the like.
