A note on projects

Reminder on reviews (3 per session March 20-April 17)

JCDL update

1. One Minute Papers

Big Points

Tension between DLs as R&D environments and production systems

Integrate different approaches (text, index terms, link) and people/machines (relevance feedback, dynamic queries)

Questions

Where do the algorithms occur in the different IR models [matching, ranking, determining link weights]

LSI??

Next steps? New developments? [semantic web?]

Will XML/SGML improve retrieval [only as good as the tagging]

How to evaluate DL?

Michael Lesk’s book?

Do DLs use classification systems such as Dewey? LC?

How to incorporate errors (e.g., 404) into retrieval [see Geisler’s example]

Effects of corporate sites restricting links to competitors on link analysis?

Did LSI folks get rich like ISI? [the researchers in both cases did not, the implementers can]

Adaptable fusion as semantic web [SW includes ontology merging]

2. Note: Markup as indexing. See McKiernan’s ASIST list postings (forwarded to class list)

3. Natural progression of services: indexing/storageàsearch/browseàreference/QA

Search and Browse are interface (client side) issues that are strongly dependent on indexing/storage/markup

The LoC NDL case http://www.cs.umd.edu/hcil/ndl/
