Editor's Summary

The 23rd SIG/CR workshop on classification research featured papers, lightning talks, brief presentations of doctoral projects and two keynote talks, all exploring what's new in the field. Under the theme of new approaches with a historical focus, presenters explored novel theories, models and applications, approaches to building classificatory structures, methods and criteria for evaluation and much more. Classification theory, concepts and terminology were considered from a historical perspective, and new theories and changes in conceptualization and classification structures were raised. Modern perspectives on classification include folksonomies, personal classification practices, power structures captured through classification and the limitations of standardization. Researchers discussed cognitive processes involved in classifying, the evolution of concepts associated with terms and sources for new terms in a domain. Through the variety of presentations, it was clear that classification encompasses a broad array of topics, ultimately serving information retrieval and access.
