    Abstract
    Purpose - The purpose of this study is twofold: to investigate whether it is meaningful to use the Engineering Index (Ei) classification scheme for browsing, and then, if proven useful, to investigate the performance of an automated classification algorithm based on the Ei classification scheme. Design/methodology/approach - A user study was conducted in which users solved four controlled searching tasks. The users browsed the Ei classification scheme in order to examine the suitability of the classification systems for browsing. The classification algorithm was evaluated by the users who judged the correctness of the automatically assigned classes. Findings - The study showed that the Ei classification scheme is suited for browsing. Automatically assigned classes were on average partly correct, with some classes working better than others. Success of browsing showed to be correlated and dependent on classification correctness. Research limitations/implications - Further research should address problems of disparate evaluations of one and the same web page. Additional reasons behind browsing failures in the Ei classification scheme also need further investigation. Practical implications - Improvements for browsing were identified: describing class captions and/or listing their subclasses from start; allowing for searching for words from class captions with synonym search (easily provided for Ei since the classes are mapped to thesauri terms); when searching for class captions, returning the hierarchical tree expanded around the class in which caption the search term is found. The need for improvements of classification schemes was also indicated. Originality/value - A user-based evaluation of automated subject classification in the context of browsing has not been conducted before; hence the study also presents new findings concerning methodology.

    Abstract
    Possibilities are being explored to use traditional bibliographic tools, like Dewey Decimal Classification (DDC), Library of Congress Classification (LCC), Library of Congress Subject Headings (LCSH), and Universal Decimal Classification (UDC), to improve the organization of information resources on the Internet. The most recent edition of DDC, with its enhanced features, has greater potential than other traditional approaches. A review of selected Web sites that use DDC to organize Web resources indicates, however, that the full potential of the DDC scheme for this purpose has not been realized. While the review found that the DDC classification structure was more effective when compared with other knowledge organization systems, we conclude that DDC needs to be further enhanced to make it more suitable for this application. As widely reported in the professional literature, OCLC has conducted research on the potential of DDC for organizing Web resources. Such research, however, is experimental and should be supplemented by empirical studies with user participation.
