LCSHtoLCC

LCSHtoLCC looks like an interesting tool. Never used it, I can't comment on how it works. Free download.
LCSHtoLCC uses a model to encapsulate the relationships between LCSH and LCC. This model is learned from a training dataset that consists of documents with both LCSH and LCC metadata assigned. Our principal dataset is based on 800,000 examples drawn from UCR's library catalog (SCOTTY).

The model itself is based on the LCC's hierarchical structure. A Support Vector Machine is built for each node in the LCC hierarchy; each can classify an example as relevant to that node or to one of its children. To classify a new example, it's LCSH are "filtered down" from the root node of the tree to more specific classifications.

Writing

Blurbs: Writing Previews of Web Pages by Dennis G. Jerz offers some good tips. Some ideas could also apply to writing summary notes in bib records. Seen on Column Two.
On the web, a blurb is a line or short paragraph (20-50 words) that evaluates (or at least summarizes) what the reader will find at the other end of a link. A good blurb should inform, not tease. Usability testing will help you determine the best way to lay out your blurbs, but this document will help you write the content.

OpenURL

Two releases from NISO Committee AX.
  • Trial Use of OpenURL Version 1.0
    NISO Committee AX on OpenURL standardization is seeking participants for a trial of the emerging OpenURL 1.0 standard. The official trial period will begin May 1, 2003 and end November 1, 2003.
  • Note and Request for Feedback on Naming Identifiers
    During the period of Public Comment and Trial Use, NISO Committee AX will be examining an important issue regarding the construction of Identifiers in the OpenURL Framework. Currently, Identifiers are constructed in one of three Naming Environments, URI, ORI, or XRI, which is indicated with one of three prefixes, "uri:", "ori:", or "xri:".

TLA

The Texas Library Association annual conference is available on CDs in MP3 format. Over 130 sessions, including some full day pre conferences, for only $89.00. I'd like to see more conferences do this. I can't get to SLA or ALA but this would be an affordable alternative.

Tag of the month

The Tag of the Month at Follett this month is not a tag, it is a sample record for a DVD. You can see the mark-up and commonly used fields, then refer back to the field descriptions they have provided in the past.

The site has been redesigned and the old URL no longer works. If you have it bookmarked, you will have to change it. Shame on them for not supplying a redirect.

MetaMap

MetaMap tripped me out.
With the exponential development of the World Wide Web, there are so many metadata initiatives, so many organisations involved, and so many new standards that it's hard to get our bearings in this new environment.

The problem is exacerbated by the fact that the names of most of these new standards are represented by acronyms. The MetaMap exists to help gather in one place information about these metadata initiatives, to try to show relationships among them, and to connect them with the various players involved in their creation and use.

The MetaMap takes the form of a subway map, using the metaphor of helping users navigate in "metaspace", the environment of metadata.

Seen on FOS News.

Access

Last month Ohio library officials were surprised when officials removed from two libraries public documents that describe local plans for responding to hazardous materials spills and other chemical emergencies. In one instance the officials posed as patrons and told librarians of their intent to remove the documents only after the reference librarian retrieved the materials and handed the material over. At a second library, the officials showed up without prior warning and flashed badges when requesting the materials. In both instances, officials replaced the documents with a one-page letter indicating the documents are available through the county's Homeland Security Office--From OMB Watch.
