Review of IS&R Systems
- information (vs. data, knowledge)
- unstructured documents
- information, library science
- effectiveness, usability
- statistics, semi-static, large
- text, electronic publishing
Clarifications
- Exercises should be turned in.
- VTLS exercise: work sheets are recommended. Required are:
- relevant retrieved
- best single query
- Remember to team on exercises, study together, etc.
- Reasonable progress: should be finishing up Unit DL.
- See instructor --- it is encouraged! (But out Wed. - Thu. this
week.)
- Boolean exercises: contrast bit vector vs. hashing approaches.
- Gopher use: gopher fox.cs.vt.edu
Select "CS5604 Information Storage & Retrieval" and then "Code for Text"
- Code in text is online in several places. But extended Boolean is
not available through the Web yet.
Programs in bool, extbool
- Look over C code, in groups
- Run executable routines and send in results for group
- Read over README files for more information
- Recommended - write own "drivers" for extra experience
