摘要： According to an example embodiment, a method comprises executing instructions by a special purpose computing apparatus to, for labeled source domain data having a plurality of original labels, generate a plurality of first predicted labels for the labeled source domain data using a target function, the target function determined by using a plurality of labels from labeled target domain data. The method further comprises executing instructions by the special purpose computing apparatus to apply a label relation function to the first predicted labels for the source domain data and the original labels for the source domain data to determine a plurality of weighting factors for the labeled source domain data. The method further comprises executing instructions by the special purpose computing apparatus to generate a new target function using the labeled target domain data, the labeled source domain data, and the weighting factors for the labeled source domain data, and evaluate a performance of the new target function to determine if there is a convergence.

摘要： An information retrieval system and computer-based method provide constructing a title for a search result summary of a document through title synthesis, wherein the title is suitable for use in assessing the relevance of the summarized document to a query. In one embodiment, the system obtains meaningful keywords or key phrases (title components) about the document; and classifies each title components into one or more of a plurality of pre-established title component classes. The title components may be automatically obtained for the document from available sources either before or at the time the document is made available for indexing by the system. When a query is input to the system to which the document is relevant, the system constructs a title for the document by arranging title components selected from title component classes, to maximize a title utility function. The title utility function may be a query-dependent grade. In addition to the query, the title utility function may also account for constraints under which the title is to be presented to a user of the system.
