    Abstract
    We are seeing a shift of the focus of information access from a data-centered to a user-centered paradigm. By a user-centered paradigm, we refer to information access that is driven not by the structure of the database in the system, but rather by views of the databases needed to satisfy an information need as perceived by the user. This paradigm relies on dynamic views that may be independent of the structure of the accessed databases. The user determines both what data is included in these dynamic views and what, if any, strucutres are imposed on the data in these views. The Daltext system is a prototype system that falls within the user-centered paradigm. it allows the user to define views dynamically. Daltext allows the user to determine what data is included in these dynamic views by specifying desired attributes and values. It allows the user to determine what, if any, structures are imposed on the data in these views by allowing the user to frame the view within a particular model. At the user's discretion, the view may be framed within a datastream model, a set model, a relational model, and/or a hierarchical model

    Abstract
    Examines the problem of the association of related times of different media type, specifically photos and stories involved in the automatic generation of electronic editions. Determines to what degree any 2 news items refer to the same news event. This metric can be used: to link multimedia items that can be shown together, such as a video, photo, and text story related to a shipwreck or state visit; and to form clusters of very similar items from a variety of sources so that 1 or 2 can be chosen to represent that event in an edition. Discusses the specific assocoation of text and photo news items, although the approach applies to a larger domain of news including scripted news video clips and sripted radio broadcasts
