Dynamic element retrieval in a structured environment
1) T | F Dynamic element retrieval is as effective as all-element and more
efficient with respect to file space.
2) T | F INEX provides an environment for experiments in structured retrieval.
3) T | F Smart is used in flexible retrieval not in all-element index.
4) T | F Exhaustivity describes the extent to which an element is “highly
focused” on the topic.
5) T | F Lnu weights are particularly useful for ranking dynamically generated
elements.
6) T | F Pivot represents the document length for which the probability of
relevance is equal to the probability of retrieval.
