Interest in information was not shifting from one medium to another but expanding to find time for more. However, children view TV as a social currency and computers as entertainment machines. 900 Shifts of Focus on Various Aspects of User Information Problems During Interactive Information Retrieval David Robins Robins reviews current models of the interactive retrieval process as a prelude to examining focus shifts as they occur in mediated retrieval. Considerably more time was spent in interaction with the system than with pre-search modeling. Search intermediaries initiated two thirds of all shifts.
Shifts occur rapidly and even chaotically.
The concentration is on strategy and evaluation with only moderate evidence of changing problem conception. Fabio Crestani Telephone access to retrieval systems involves voice recognition as well as efficient database searching in a noisy interactive environment. Tombros and Crestani look at user perception of the relevance of document summaries presented vocally in the context of the Sonification of an Information Retrieval Environment, or SIRE project at the University of Glasgow. SIRE interactively converts telephone speech to query text for a probabilistic retrieval system, that then converts high ranked results to vocalized summaries for relevance judgment by the user. Summarizations ranked sentences by position, field, and high score based on the number of high document frequency words present, and a length normalized query score based on query terms present.
