摘要： 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.

摘要： 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.
摘要翻译：一种全文格式索引和搜索系统和方法，用于使用文本索引器索引字格，以增强对音频内容的搜索。该系统和方法利用代表字格的时间锚定格子扩展（TALE）方法，使得它们可以用很少或没有修改的现有文本索引器进行索引。系统和方法的实施例包括用于基于音频内容生成和索引字格的索引模块和用于允许搜索包含索引的字格的全文索引的搜索模块。索引模块包括一个自定义的IFilter和一个自定义的Wordbreaker。搜索模块的实施例包括用于装饰输入查询和定制Stemmer的ExpandQuery函数。搜索模块的实施例还包括GenerateSnippets模块，该模块从索引的字格架提取信息，以创建可点击的片段。
