Albuquerque, NM (June 3, 2013) – Access Innovations, a leading firm in information retrieval, has teamed with the Public Library of Science (PLOS), a non-profit multi-disciplinary publisher and advocacy organization, to create a customized thesaurus to enhance search retrieval. The new, NISO Z-39.19-compliant thesaurus includes more than 10,000 terms and 3,300 synonyms, which will enhance search retrieval tenfold. Gabe Carr, PLOS project manager at Access Innovations, explained the ground-breaking nature of the project. “With a broader range of granular subject terms and improved tagging accuracy, the new thesaurus will make PLOS content even more accessible to professionals, researchers, and casual readers like me. We’re proud to be involved with a pioneering organization like PLOS.” Because PLOS doesn’t specialize in publishing any one subject area, but rather publishes content across all biomedical fields as well as disciplines as diverse as information science and paleontology, the first step was to create a controlled vocabulary to suit PLOS’s needs. Access Innovations drew upon an internally created science, technology, engineering and medicine thesaurus (STEM), identifying some 15,000 candidate terms for inclusion in the thesaurus. Marjorie M. K. Hlava, president of Access Innovations, said developing a controlled vocabulary for the multidisciplinary publisher was an important first step: “If you think of the word mercury, for instance. In astronomy, Mercury is a planet. In chemistry, it’s an element. It all depends upon the context and usage. In a multidisciplinary project such as this, it’s important to identify the terms that will need disambiguation.” After being reviewed by subject matter experts (SMEs), the result was a 10,400-term thesaurus comprising seven tiers. The ten top-tier terms are: 1. Biology and life sciences; 2. Computer and information science; 3. Earth sciences; 4. Engineering and technology; 5. Environmental science and ecology; 6. Medicine and health sciences; 7. Physical sciences; 8. Research and analysis methods; 9. Science policy; and 10. Social sciences. John Chodacki, director of product management at PLOS, said the key to creating the new thesaurus was cooperation and collaboration among PLOS’s thesaurus development team and Access Innovations editors. “Organizing and categorizing the PLOS content is a daunting task because we publish across a broad range of topics. Access Innovations was the perfect partner to keep the project on track and on time. Together we quickly defined the vocabulary, organized it into a thesaurus, applied terms to our existing corpus, and set up systems to add terms to new articles as they are published.”
