....however, we believe that aggregation will be a frequently used query operation. This is especially true in interactive settings: user studies of information analysts have shown that the first request is often for a big picture of the data, which is used to decide what other questions to ask [29]. Energy efficient Aggregation Energy efficiency can be achieved using approximate aggregates. We have argued in Section 3 that a sensornet database can provide approximate results to queries. Approximate aggregates are useful for on line monitoring, can reduce the communication costs, and ....

....set , using a number of different search strategies. The user may be unwilling or unable to express her requirement in a single detailed query, and may prefer to browse the collection, or issue a series of simple queries. Subsequently, evidence for this model was provided by O Day and Jeffries [83] who found that, based on what a user learned from the documents returned by an initial query, her requirement would often shift, resulting in a series of interconnected requests. Relevant information was progressively gathered from these, rather than entirely from the initial query. The test ....

A more developed IF will come into its own when considering the interactional requirements of more advanced information seeking and management patterns such as those discussed by O Day and Jeffries [10]. In their work they discussed information orienteering and the various techniques people employ in getting from one piece of information to another. IF s current notions of blind alley interactions, interactional traps, and detours will provide purchase on the issues of how users move around ....

Each new piece of information a user encounters gives them new ideas and directions to follow and, consequently, a new conception of the search. Furthermore, at each stage, with each new conception of the search, the user may identify ....

....searching evolves over a period of time and relies on users being able to follow new (interesting) paths as they appear, which may not necessarily have been specified at the start of their search. These notions of extended searching are supported by research carried out in conventional libraries [14]. As with digital library studies, ODay Jeffries found that one shot searches were rare. Rather, they found that single searches evolved into other kinds of searching which they identified as: monitoring a topic over time; following an information gathering plan; and exploring a topic in an ....

....studies, empirical evaluation 1. THE PROBLEM Digital library users tend to use computers and paper together when engaged in interactive information retrieval tasks. Library clients may read piles of search results using paper copies, even when the material had been delivered electronically [17], and many information analysts make hardcopies of source materials, and mark up the pages (Catherine C. Marshall, personal communication) This search and print reality contrasts with the search and read ideal held by digital library researchers (e.g. 3] In general, we believe that ....

.... queries from users freeform ink annotations [19] People often use free form ink annotations to help them understand their reading [1] 12] In particular, information seekers use annotations to manage printed search results: they mark up relevant passages with highlights and brief marginalia [17], 13] Thus, freeform ink annotations can reveal which aspects of the underlying documents are of interest, and by observing these marks, XLibris can discover people s interests without requiring additional effort from them. XLibris interprets readers freeform ink annotations as selections of ....

Analysts should be given continual feedback for queries, and a simple, intuitive interface for specifying and refining them. 1.1 Problems with current data analysis methods Lack of interactivity: Many current mechanisms ....

Management and refinement of search results is a feature of a trader UI that is underdeveloped and can be improved. 2.1.1 Changing information needs Supporting changing information needs in a trader UI is a little more difficult. O Day and Jefferies [9] made a key observation in trying to understand changing information needs. Their observation was that there was some decision that led to the next step in the interconnected search: a trigger . These triggering actions where the result of encountering something interesting, or explaining a ....

There are several ways in which this could be done: using maps, random guesswork, following other people or asking for directions [Dieberger, 1993, O Day, 1993] The latter two of these options require our agent to be able to communicate effectively with other agents, both human and software.

Workcenters and their contents persist over time, allowing users to come back and continue a task at a later date. This is consistent with our reading of the library use literature [Marc95, Nard96, Oday93]. Persistence also reinforces the notion that the workcenter is a place, and supports sharing. DLITE is designed so that multiple users can interact with the same workcenter from different physical locations at the same time. This collaboration mechanism will be presented in a later paper. 3. ....

Similarly, [9] observes that from search session to search session, our searchers used data from their present situation to determine where to go next.
