Copernic Summarizer // FW: Metadata Conversion and the Library OPAC

[ernest perez]

Web4Lib people,

Here's two messages in one.... I append below a "summary" produced by the new Copernic product called "Summarizer 1.0". This product does text analysis on a document in formats of common wordprocessor file, text file, Web page, or in Clipboard. It then extracts a summary and a list of relevant key terms. Length and # of keywords can be set with a slider.  

Interesting possibilities for metatagging, description text, etc. Or for a quick 'n cheap abstracting service for your information clientele?

More info on Summarizer at <http://www.copernic.com/products/summarizer/>.

Cheers,
-ernest

The following "abstract" (??) took about 5 seconds in Summarizer. 
This resulted from  auto-analysis and summary of "Metadata Conversion 
and the Library OPAC," by Amanda Xu, at <http://web.mit.edu/waynej/www/xu.htm>. 

This sample of the Copernic product output resulted from Ms. Xu's 11-page 
HTML document. It's not an easy text to summarize. 

You may be interested in comparing the summary to the original. 
Do YOU think it's a decent summary?

SUMMARY

Metadata Conversion and the Library OPAC

This development has pointed up the need for applying metadata to networked information resources, as it has been widely accepted that resources with metadata attached or embedded have the potential to be more easily discovered and retrieved via the Internet.

It suggests using the OPAC as a gateway to access the metadata repository, whether it is located on the library Website, or on the local databases mounted with specialized metadata formats.

As a result, both locally created metadata and incoming metadata selected as part of the library collection can be captured via automatic metadata extraction, mapping, conversion, and integration.

It contains a set of data elements to describe the content and location of an information object and to facilitate its discovery and retrieval in the networked environment.

It differs from other metadata in that it uses AACR as rules for data modelling, USMARC for encoding schemes, and prioprietary online systems for information retrieval for more than three decades.

Not all resources with metadata attached will be discovered by search engines, because the types of metadata a search engine gathers depends largely on the types of metadata templates that are profiled.

The databases such as bibliographic databases, citation databases, and finding aids in which OPACs are directly indexed, or interfaced have served as library metadata repositories for years.

A systematic and standard approach to all of the librarys resources is required.

Therefore, if library OPACs are used as gateways to access all the databases, including metadata repositories either on library Web sites or on local databases, a metadata conversion system built into the gateway is needed to ensure metadata interchange.

Therefore, due to the limitation of current technology, using one type of metadata that has been profiled and implemented with Z39.50 as the base format for all the other metadata formats seems to be a practical approach.
