MAILib™
For those using Library of Congress Subject Headings (LCSH) in categorization of documents and publications, this extension of MAIstro allows you to use the 208,000 LCSH terms as your controlled vocabulary.
Or, use an existing Thesaurus. MAILib™ can logically connect each term with a corresponding LCSH.
MAILib's rule-based system is designed to be made more effective with the fine tuning produced by human interaction. Using an initial set of documents that represent the breadth of your collection, MAILib returns hits, misses and noise. You modify the automatically generated rules to reduce the misses and ignore the noise. When you have achieved the desired level of accuracy (percentage of hits), the software can automate the indexing task for you.
MAILib incorporates the entire 208,000-term set of LCSH with tools to combine headings and subheadings, following detailed standards set in MARC 21 and the Anglo-American Cataloging Rules, Second Edition. With MAILib, users are able to speed and expand their cataloging using LCSH terms, exporting results in MARC (expanded or concise), XML, or other output formats.
"We believe that our MAILib system is a significant step in the field of information management," said Access Innovations president Hlava. "For the first time, we are giving managers of electronic information resources the ability to combine the precoordinate system of cataloging done by libraries with the indexing systems used in the electronic information arena. Our system gives a new power to information managers to leverage their information assets."
Here’s an example of how MAILib works: It takes text such as, "Classic to ultramodern, Big Apple theaters showcase the full spectrum of design…," roots out the words and concepts represented in the LCSH, assigns headings and subheadings, and then links the components, constructing complete and valid precoordinated strings according to LCSH rules. The result:
Theaters > Decoration > New York (N.Y.).
It’s not just publishers and database producers that the product can aid, but also online and Web-based directory publishers, academic and corporate libraries, Web search engines, Web portals, and corporations and associations with large intranets. The new MAILib system adds a new level of sophistication to the process of turning unstructured data into structured information assets that can be used for any number of business or research purposes.
