106results about How to "Strong association" patented technology

A system for providing collaborative tag sets to assist in the navigation and use of a folksonomy. The collaborative tag sets are social in nature. As more users group two tags together into tag sets, the disclosed system causes the association between those two tags to grow stronger, as exposed in the bookmark system user interface when alternative tags are suggested for browsing the bookmarks in a folksonomy. Tags that are grouped together by a user into a tag set have the strongest possible weight for that user, and accordingly the disclosed system automatically applies all tags in a set when that user is retrieving bookmarks if the user selects at least one of tags in the set. Tags not in the user's tag sets, but included in the public tag set(s) of another user(s) are displayed in the user interface as tag suggestions.

Behavior-based associations are extrapolated to items for which the quantity of collected user activity data is insufficient to create meaningful or reliable behavior-based associations (“behavior-deficient” items). The behavior-based associations are extrapolated based on content-based associations, or another type of “substitutability” association, between the behavior-deficient items and other items. The items can be any type of item for which user behaviors (e.g., purchases, accesses, downloads, etc.) can be monitored and analyzed to detect behavior-based associations, and for which item content or other available information can be used to assess item substitutability. For example, the items can be products represented in an electronic catalog, web pages or other documents accessible on a network, or web sites.
