Abstract: Systems and methods for generating navigation filters are provided. A target resource is parsed and occurrences of data entries representing archetypal headings and/or archetypal items for a navigation filter are identified in the content of the target resource. A path to each of the identified occurrences is determined and used to construct a query for additional navigation filter headings and/or navigation filter items that have the same path as an identified occurrence. Identified occurrences of archetypal data entries in the target resource and the additional content having the same path as an identified occurrence are used as potential navigation filter headings and/or potential navigation filter items. Navigation filters are generated by associating one or more of the potential navigation filter items with one of the potential navigation filter headings.

Abstract: Methods and apparatus are described herein for selecting, from one or more electronic data sources, a candidate textual statement associated with an entity, identifying one or more attributes of the candidate textual statement; and determining, based on the identified one or more attributes of the candidate textual statement, a measure of suitability of the candidate textual statement for presentation as a testimonial about the entity.

Abstract: Methods and apparatus for determining a tone differential between a given segment of a document and a larger segment of the document. The tone differential may be based on comparison of a first tone associated with the given segment and a second tone associated with the larger segment. The tone differential is indicative of the variance between the tone of the given segment and the tone of the larger segment.

Abstract: Methods and apparatus are described herein for classifying user reviews or portions thereof as being related to various entities, and for associating extracted descriptive segments of text contained in those user reviews or portions thereof with entities based on the classifications. In various implementations, one or more categories of observed user interest may be identified based on a corpus of user queries. One or more segments of text related to the one or more categories of observed user interest may be detected in one or more user reviews associated with a product. Based on the detecting, the product may be indexed on the one or more categories of observed user interest in a searchable database. In some implementations, the searchable database may be accessible to one or more remote client devices, and may be searchable by the one or more categories of observed user interest to provide search results to be rendered by the one or more remote client devices.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system for providing content and that includes subsystems. An attribute inference subsystem analyzes content items and tags each content item with attributes that may affect performance and that are related to attribute types selected from a group comprising content concepts, format, included content, semantics or syntax. Attributes can be identified by the attribute inference subsystem or a sponsor of a respective content item. An analysis subsystem evaluates a log of served content items that have been tagged to identify salient attributes related to one or more performance metrics and inferences related to the identified salient attributes. An experiment subsystem automatically creates one or more experiments to substantiate the inferences related to the identified salient attributes.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a system that includes a synthesis subsystem that automatically creates components for inclusion in a creative. The synthesis subsystem includes one or more modules that receive, as input, crawled content or metadata known or identified by the content serving system, and produce, as an output, a synthesized component for inclusion in a prospective creative. The system further includes an evaluation subsystem that evaluates quality of each of the synthesized components generated by the synthesis subsystem to determine measurable quality as against a baseline quality level.

Abstract: Methods and apparatus are described herein for classifying user reviews or portions thereof as being related to various entities, and for associating extracted descriptive segments of text contained in those user reviews or portions thereof with entities based on the classifications. In various implementations, one or more portions of a corpus of user reviews may be classified as being related to a first entity or a second entity. One or more descriptive segments of text may be extracted from the one or more classified portions. The one or more extracted descriptive segments of text may be associated with the first or second entity based on classifications of the one or more classified portions.

Abstract: Systems and methods for providing navigation filters within content items distributed via a computer network are provided. A navigation filter includes a heading and a plurality of items associated with the heading and can function as a summary of a resource associated with a distributed content item. A described method includes receiving a request for content from a user device, selecting a content item in response to the request, identifying one or more navigation filters associated with the selected content item, generating display data including the selected content item and the one or more navigation filters, and providing the display data for presentation to the user device.
