In one embodiment, a method includes receiving a request from a first user of an online social network, the request comprising a character string of one or more characters of text entered by the first user, identifying a first set of objects associated with the online social network matching at least in part the character string of the request, calculating a score for each identified object in the first set of objects, wherein the score for each identified object is based at least in part on connections between the first user and the identified object, and sending one or more suggested queries responsive to the request, each suggested query comprising the character string of the request and one or more keywords associated with one or more of the identified objects, wherein the suggested queries are displayed in a ranked list based on the calculated scores of the associated identified objects.

Generating suggested queries based on social graph information

Embodiments improve the ability of users of a social networking system to search for information that is likely to be relevant to them by learning and/or applying a search context associated with selector components used to search for objects of the social networking system. The search context is specific to the use of an individual selector and thus need not be as general as the context of an entire page or set of pages in which selectors can be embedded. The social networking system may learn the context of a selector by monitoring user selections from prior search results performed using the selector.

Context-based object retrieval in a social networking system

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users of the social networking system using the metapages generated for the concepts. Aggregated social information may be presented to users of the social networking system viewing a page associated with a metapage. In one embodiment, a best page may be determined for a user based on information about the user.

Searching topics by highest ranked page in a social networking system

In one embodiment, a method includes receiving, at a query form associated with a social network environment, a request from a first user of the social network environment, the request comprising a character string entered by the first user, identifying objects associated with the social network environment matching at least in part the character string of the request, and sending, to the query form for display to the first user, one or more suggested queries responsive to the request, wherein each suggested query comprises the character string of the request and references to one or more of the identified objects.

Automatically generating suggested queries in a social network environment

A flywheel device includes structures allowing the flywheel system to be assembled offsite, transported safely, and installed with relatively few steps. The flywheel includes a rotor and a housing enclosing the rotor, where the housing includes a bottom plate, a top plate and side walls. The bottom plate and the top plate each includes a hole aligned with the center axis of the rotor. The flywheel also includes multiple bearing housings substantially covering the holes of the bottom plate and the top plate that are aligned to the center axis of the rotor. The flywheel also includes posts that physically contact the primary rotational mass of the rotor to prevent motion of the rotor during transport of the flywheel system. Some or all of these posts may be repositioned or removed during installation so that the rotor can spin freely.

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users using the metapages generated for the concepts. Aggregated social information may be presented to users viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. Information on other external websites associated with the metapage may be presented as links on the pages associated with the metapage. Feedback from users may be used to include or exclude pages from being associated with a generated metapage. A best page for a concept embodied in multiple pages may be determined using a hierarchy of rules.

Embodiments of the subject invention are directed to a flywheel rotor that includes two or more sub-rotors stacked one on top of another, in which each sub-rotor is rotationally symmetric and disk shaped, where the axial centers of each sub-rotor in the stack are rotationally aligned, and each sub-rotor has an upper and a lower journal that extends outward from the origin of the center section of the primary rotational mass of the sub-rotor. Each pair of adjacent sub-rotors in the stack has a lower journal of an upper sub-rotor that is disposed above an upper journal of a lower sub-rotor. Also, there is a joining mechanism between each pair of adjacent sub-rotors that fixedly connects the lower journal of the upper sub-rotor to the upper journal of the lower sub-rotor.

Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users of the social networking system using the metapages generated for the concepts. Aggregated social information may be presented to users of the social networking system viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. A best page may be determined for a concept embodied in multiple pages on the social networking system using a hierarchy of rules. A best page may also be determined for a user based on information about the user.

In one embodiment, a method includes maintaining a data store of nodes and edges and for each of one or more users: scanning items of content associated with the corresponding user node; identifying a candidate item of content; searching for matches between the candidate item of content and existing nodes; determining whether or not a match between the candidate item of content and an existing node exists; and when it is determined that at least one match exists, generating an edge from the user node to the existing node for which the best match is determined; and when it is determined that no match exists, generating a new node based on the candidate item of content, and generating an edge from the user node to the new node.
