Abstract: A full-text lattice indexing and searching system and method for indexing word lattices using a text indexer to enable enhance searching of audio content. The system and method utilize a Time-Anchored Lattice Expansion (TALE) method that represents word lattices such that they can be indexed with existing text indexers with little or no modification. Embodiments of system and method include an indexing module for generating and indexing word lattices based on audio content and a searching module for allowing searching of a full-text index containing indexed word lattices. The indexing module includes a custom IFilter and a custom Wordbreaker. Embodiments of the searching module include an ExpandQuery function for decorating an input query and a custom Stemmer. Embodiments of the searching module also include a GenerateSnippets module that extracts information from the indexed word lattices to enable the creation of clickable snippets.

Abstract: A generalized discriminative training framework for reconciling the training and evaluation objectives for document similarity is provided. Prior information about document relations and non-relations, are used to discriminatively train an ensemble of document similarity classification models. This result is a model set that can be used to compute similarity between seen documents in the training sets and new documents. The measure of similarity forms the basis of recommending documents to a user as well as being able to obtain metadata information such as keywords and tags for new documents not having such information.

Abstract: A new way of providing search results that include audio/video thumbnails for searches of audio and video content is disclosed. An audio/video thumbnail includes one or more audio/video segments retrieved from within the content of audio/video files selected as relevant to a search or other user input. For an audio/video thumbnail of more than one segment, the audio/video segments from an individual audio/video file responsive to the search are concatenated into a multi-segment audio/video thumbnail. The audio/video segments provide enough information to be indicative of the nature of the audio/video file from which each of the audio/video thumbnails is retrieved, while also fast enough that a user can scan through a series of audio/video thumbnails relatively quickly.
