  • Inverse search systems and methods
    Patent number: 8886627
    Abstract: 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.

  • Search system and methods with integration of user annotations from a trust network
    Publication number: 20140289232
    Abstract: 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.

  • Lateral Search
    Publication number: 20140195511
    Abstract: 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.

  • Search Systems and Methods with Integration of User Annotations
    Publication number: 20140114947
    Abstract: 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.

  • Method and apparatus for resorting a sequence of sorted strings
    Patent number: 8549023
    Abstract: A method and apparatus for resorting a sequence of sorted strings, wherein the sequence of sorted strings is obtained by sorting a plurality of strings based on a first character collation standard and the resorting is based on a second character collation standard. A method in accordance with an embodiment of the invention includes: comparing the first character collation standard with the second character collation standard to obtain a change of the character collation standard; and resorting the sequence of sorted strings based on the change of the character collation standard. The method of the present invention takes the change of the character collation standard and its affection to the sequence of sorted strings into consideration, and can resort the sequence of sorted strings quickly and thus save time for resorting.

  • ADAPTIVE PRECISION ARITHMETIC UNIT FOR ERROR TOLERANT APPLICATIONS
    Publication number: 20130246497
    Abstract: Two process-tolerant arithmetic circuit architectures are implemented to develop functional blocks for error-tolerant applications such as FIR filters and FFT blocks. The resulting blocks may achieve computational performance of up to 42 times higher than conventional architectures. Embodiments adaptively change the precision of the computation to achieve a high precision computation given the underlying speed of the circuit. The resulting improvement can be allocated to increasing yield or dynamically trading off between reduced power consumption, faster computation, or higher-fidelity computation.
