Publication number: 20140289232Abstract: Computer systems and methods incorporate user annotations (metadata) regarding various pages or sites, including annotations by a querying user and by members of a trust network defined for the querying user into search and browsing of a corpus such as the World Wide Web. A trust network is defined for each user, and annotations by any member of a first user's trust network are made visible to the first user during search and/or browsing of the corpus. Users can also limit searches to content annotated by members of their trust networks or by members of a community selected by the user.Type: ApplicationFiled: May 30, 2014Publication date: September 25, 2014Applicant: Yahoo!

Publication number: 20140195508Abstract: A search query is received. Personal information for a user is then determined. A search is performed in a general subdomain of general content using the search query. For example, the general subdomain of general content may be a WWW search. Then, a vertical subdomain is determined based on the personal information. A search is then performed in the vertical subdomain of specialized content using the search query. The search performed in the general subdomain and the search performed in the vertical subdomain generate general search results and vertical search results. The results may be combined and outputted to a client.Type: ApplicationFiled: March 12, 2014Publication date: July 10, 2014Applicant: Yahoo! Inc.Inventors: Qi Lu, John Thrall, David Ku

Publication number: 20140114947Abstract: Computer systems and methods allow users to annotate content items found in a corpus such as the World Wide Web. Annotations, which can include any descriptive and/or evaluative metadata related to a document, are collected from a user and stored in association with that user. Users are able to annotate and view their annotations for any document they encounter while interacting with the corpus, including hits returned in a search of the corpus. Users are also able to search their annotations or to limit searches to documents they have annotated. Metadata from annotations can also be aggregated across users and aggregated metadata applied in generating search results.Type: ApplicationFiled: December 30, 2013Publication date: April 24, 2014Applicant: Yahoo!

Publication number: 20140108387Abstract: Inverse search systems and methods operate on identifiers of content items in a corpus such as the World Wide Web In an inverse search, the user submits a query that includes an identifier of a target content item in the corpus and receives information (metadata) about the target content item being returned to the user. Many types of metadata can be returned, including ratings or other metadata related to the target content item obtained from users, popularity data specific to the target content item, information about previously submitted forward search queries that led to the target content item being identified as a hit, and metadata extracted from the target content item.Type: ApplicationFiled: December 11, 2013Publication date: April 17, 2014Applicant: Yahoo!

Patent number: 8521734Abstract: Embodiments of the present invention provide systems and methods for ranking a result set. The method according to one embodiment comprises selecting an item from the result set, selecting a user profile from one or more user profiles and selecting one or more items of personalized information from the selected user profile. A rank is calculated for the item on the basis of the selected one or more items of personalized information and the selected item in the result set is ranked in accordance with the calculated rank.Type: GrantFiled: July 28, 2011Date of Patent: August 27, 2013Assignee: Yahoo!

Publication number: 20130071271Abstract: A valveless, pulsatile, non-contact, positive displacement, finger-pump for pumping one or more fluids is disclosed. The pump can include one or more channels for holding one or more lengths of flexible tubing. The channels can include an adjustment mechanism and/or a resilient backing plate to reduce over compression of the tubing. The pump can utilize a plurality of profiled, pivoting fingers to sequentially occlude a length of tubing causing a pumping action. The fingers can be moved from the first position to the second position by a motor driven camshaft. Cam lobes disposed on the camshaft can be a modified eccentric design to improve tube occlusion and pump efficiency. At least one cam lobe can completely occlude the tubing at all times during operation to prevent backflow. The fingers can alternatively be moved from the first position to the second position by a variety of linear actuators.Type: ApplicationFiled: March 17, 2011Publication date: March 21, 2013Inventors: David Rosen, David Ku, Jane Kang
