Question

True or False (Information Retrieval)

1) Compression of entries in the term-document matrix can be used to reduce run-time storage and execution-time requirements.

2) Once the documents in a collection have been indexed, it sometimes makes sense to compress them until they’re needed in response to a user’s query.

Answer 1

Information Retrieval:

1). True:

   Compression of entries decrease the size which helps us save storage and after compression it takes less time to process data because compression makes bigger block data into small package.

2). True:

When a collection has been indexed we can compress data because an indexed collection is a proper method and after compressing it saves time in execution when the user enter to the related query only on that moment data will be extracted for what so ever purpose.
