Abstract: Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to customize displayed content in a document, such as a web page or a user interface in a software application. In particular, by monitoring user activities while one or more users view the document during multiple sessions, the computer system can identify the most relevant content at a particular time. Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity. For example, the computer system may selectively filter the content in the document so that a subset of the content is displayed. Moreover, the displayed content may be dynamically revised based on subsequent user actions.

Abstract: One embodiment of the present invention provides a system that facilitates defining relationships between tags. During operation, the system receives a user-specified tag that describes a data item. Next, the system displays this tag to a user via a user interface that gives the user the option to suggest additional relationships for the tag. Based on user input, the system may define a relationships between the two tags, thereby facilitating the definition of a set of related tags for an organization.
