  • Publication number: 20110314396
    Abstract: Personal portal pages for individual users are integrated with web content syndication. For example, when a search query is received from the user, a list of hits is generated. For each hit, it is determined whether there is an associated syndication feed, such as an RSS feed. The list of hits is displayed for the user, and a syndication option is included for each hit that has an associated syndication feed. The user can select the syndication option and thereby subscribe their personal portal page to that syndication feed. In some embodiments, the user may also be able to select syndication feeds for subscription via an alternative interface.

  • Publication number: 20110213805
    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.
