This research aimed to explore whether subject facets would increase patron use of subject headings in a faceted (Yufind) versus a non‐faceted (Orbis) catalog interface at Yale University.

Two rounds of think aloud protocol testing were done with students to measure the acceptance and use of subject heading facets. After a faceted and non‐faceted interface were implemented, side‐by‐side, log file analysis was employed to measure and compare use of subject headings in both interfaces.

Initial usability testing showed that patrons would try facets, but had some problems effectively using them. In production from January to May 2011, at least one facet was used in 25.4 percent of Yufind searches, and subject facets were used in 5.1 percent of searches, while in Orbis subject headings were used in 6.4 percent of searches. Facets were used less than subject heading links in records in either interface.

The findings are important as libraries spend significant staff time adding subject headings to records, and their use by patrons is declining. As measured in two production systems running on exactly the same catalog records, subject heading facets did not successfully increase use of subject headings. Without further refinements, faceted display may not be a successful strategy to increase patron use of subject headings.

A comparison of patron generated subject heading use in two concurrently running interfaces, one faceted and one not, has not been done before.

The purpose of this paper is to explore the potential of enriching the library subject headings with folksonomy for enhancing the visibility and usability of the library subject headings.

The WorldCat-million data set and SocialBM0311 are preprocessing and over 210,000 library catalog records and 124,482 non-repeating tags were adopted to construct the matrix to observe the semantic relation between library subject headings and folksonomy. The proposed system is compared with the state-of-the-art methods and the parameters are fixed to obtain effective performance.

The results demonstrate that by integrating different semantic relations from library subject headings and folksonomy, the system’s performance can be improved compared to the benchmark methods. The evaluation results also show that the folksonomy can enrich library subject headings through the semantic relationship.

The proposed method simultaneous weighted matrix factorization can integrate the semantic relation from the library subject headings and folksonomy into one semantic space. The observation of the semantic relation between library subject headings and social tags from folksonomy can help enriching the library subject headings and improving the visibility of the library subject headings.

This paper puts forward a MARC-based semiautomated approach to extracting semantically rich subject facets from general and/or specialized controlled vocabularies for display in topic-oriented faceted catalog interfaces in a way that would better support users' exploratory search tasks.

Hierarchical faceted subject metadata is extracted from general and/or specialized controlled vocabularies by using standard client/server communication protocols. Rigorous facet analysis, classification and linguistic principles are applied on top of that to ensure faceting accuracy and consistency.

A shallow application of facet analysis and classification, together with poorly organized displays, is one of the major barriers to effective faceted navigation in library, archive and museum catalogs.

This paper does not deal with Web-scale discovery services.

This paper offers suggestions that can be used by the technical services departments of libraries, archives and museums in designing and developing more powerful exploratory search interfaces.

This paper addresses the problem of deriving clearly delineated topical facets from existing metadata for display in a user-friendly, high-level topical overview that is meant to encourage a multidimensional exploration of local collections as well as “learning by browsing.”

An empirical study has shown that the real process of subject cataloging does not correspond entirely to theoretical descriptions in textbooks and international standards. The purpose of this is paper is to address the issue of whether it be possible for catalogers who have not received formal training to perform subject cataloging in a different way to their trained colleagues.

A qualitative study was conducted in 2001 among five Slovenian public library catalogers. The resulting model is compared to previous findings.

First, all catalogers attempted to determine what the book was about. While the American catalogers tried to understand the topic and the author's intent, the Slovenian catalogers appeared to focus on the topic only. Slovenian and American academic library catalogers did not demonstrate any anticipation of possible uses that users might have of the book, while this was important for American public library catalogers. All catalogers used existing records to build new ones and/or to search for subject headings. The verification of subject representation with the indexing language was the last step in the subject cataloging process of American catalogers, often skipped by Slovenian catalogers.

The small and convenient sample limits the findings.

Comparison of subject cataloging processes of Slovenian and American catalogers, two different groups, is important because they both contribute to OCLC's WorldCat database. If the cataloging community is building a universal catalog and approaches to subject description are different, then the resulting subject representations might also be different.

This is one of the very few empirical studies of subject cataloging and indexing.
