August 3, 2010 – Access Innovations, Inc. has collaborated with the American Institute of Physics (AIP), to convert AIP’s Physics and Astronomy Classification Scheme (PACS) into a thesaurus for its nearly two million online scholarly articles indexed by PACS. Using the new thesaurus allows scientists to execute faster, more accurate and more efficient information searches.

“We’ve worked diligently to archive articles from our journals and conference proceedings as a valuable and convenient resource for researchers worldwide,” said Mark Cassar, publisher of journals and technical publications at AIP. “Unfortunately, the articles have become increasingly hard to find. The new thesaurus, however, represents a major step forward, as it allows researchers to achieve successful searches in much less time.”

PACS uses a decimal-based, six-digit alphanumerical notation classification scheme, arranged in a hierarchical format, which is limited to 10 top terms and nine second-level terms. In the past, this classification system resulted in multiple concepts expressed within the same term, and was not search friendly.
