Data retrieval
The concept "data retrieval" is sometimes used as opposed to information retrieval (and sometimes also as as opposed to "question answering systems", fact retrieval).
Van Rijsbergen (1990)
characterizes the difference between data retrieval and information retrieval by
the following scheme:
|
