Abstract: A method for tagging and organizing data is provided. In one example, physiological data detected from a wearer of a wearable device is received and associated with a tag based, at least in art, on an input by the wearer. The input may be a state of the wearer, such as physical or mental state, or a rule. The collected physiological data may be organized based on the tag and, in some examples, on other types of received data, such as a wearer's personal data. In other example methods, data may be stored in a database based on one or more tags associated with the data.

Abstract: Methods and apparatus for providing rule-based access to data stored on wearable devices are provided. A wearable computing device can store data that includes data about a wearer of the wearable computing device. The wearable computing device can receive a request for a portion of the stored data. The wearable computing device can determine a designated role associated with the request for the portion of the stored data. The wearable computing device can determine one or more rules regarding access to the portion of the stored data based on the designated role. The wearable computing device can determine a response to the request for the portion of the stored data by at least: determining whether the request is validated by at least applying the one or more rules to the request, and after determining that the request is validated, providing the requested portion of the stored data.

Abstract: An interactive web site summary system builds an overview browsing system for the entire Web. Overview browsing represents an alternative to the search-based view of information work by providing a consistent set of summary views that can be browsed interactively. The views presented by the present system partition and linearize a corpus for ready understanding and exploration. These views show features of a web site such as, for example, the relation of a web site to other web sites, the broad nature of the information contained in the web site, how the web site is structured, how the web site has changed over time. The interactive web site summary system maintains such summary information in a process that is fast enough to be updated daily.

Abstract: A Web server stores a table of Web page inlinks. When a Web page is accessed and a user wants to access other pages related to the accessed page, the user requests the table of inlinks, and from it generates a list of sibling links to the accessed page, the sibling links being outlinks of one or more of the inlinks in the table.

Abstract: A system and method are provided for eliciting interesting structure from a collection of entities or resources with explicit and/or implicit, static and/or dynamic relations, called “affinities,” between them. Interesting structure includes (1) notions of quality, authority, or definitiveness of information, (2) notions of relevance to a user's information need, (3) notions of similarity among the plurality of resources retrieved from a universe of resources by a query process, and (4) notions of similarity among the usages of resources by different users/servers. Similarities between entities are computed, based on similarities between the affinity values for the entities. That is, where the affinitiy values for two entities resemble each other, the two entities have a high degree of similarity. Using the similarities, the entities are ranked, clustered, etc., based on a significance derived from the similarities. The ranking, clustering, etc., makes up the interesting structure which is sought.

Abstract: A method for identifying, filtering, ranking and cataloging information elements; as for example, World Wide Web pages, of the Internet in whole, part, or in combination. The method is preferably implemented in computer software and features steps for enabling a user to interactively create an information database including preferred information elements such as preferred World Wide Web pages in whole, part, or in combination. The method includes steps for enabling a user to interactively create a frame-based, hierarchical organizational structure for the information elements, and steps for identifying and automatically filtering and ranking by relevance, information elements, such as World Wide Web pages for populating the structure, to form; for example, a searchable, World Wide Web page database.
