The original aim of this study was to obtain objective data bearing on the much argued question of whether author indexing is “good.” Author indexing of 285 documents reporting biomedical research was scored by comparing the author-supplied terms (author set) for each paper with a criterion set of terms that was established by asking a group of 12 potential users to describe the same document. Terms in the document title (title set) were scored similarly. The average author set contained almost… 

Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing

This paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers and suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories.

Written representation of topics and the production of query terms

The results of an experiment simulating a library catalog search indicated that a relation exists between the lexical content load of the text, used to define the search topic, and the number of query terms generated by a group of experimental subjects (college students).

Indexing Consistency and Quality.

A measure of indexing consistency is developed based on the concept of “fuzzy sets.” It assigns a higher consistency value if indexers agree on the more important terms than if they agree on less

The functions of abstracts in the initial screening of technical documents by the user

There does not appear to be any evidence to support the assumption that abstracts, accompanying a document, have any significant effect.

Controlled vocabularies and tags: An analysis of research methods

Tagging and controlled vocabulary studies are explored in the context of earlier studies examining title keywords, author keywords and user indexing and results show that author and title keywords and tags are more similar to each other than to subject headings.

Syntagmatic relationships and indexing consistency on a larger scale

The authors applied basic data modeling and the exploratory statistical techniques of multi‐dimensional scaling (MDS) and hierarchical cluster analysis to determine whether relationships exist in indexing consistency and the coocurrence of assigned terms.

Less than full-text indexing using a non-boolean searching model

The hypothesis of the study was that by using a particular non‐Boolean method as a file structuring and searching technique, full‐text indexing is not essential to optimum information retrieval effectiveness.

Measuring consistency for multiple taggers using vector space modeling

Tagging data for scholarly articles made available by the social bookmarking Website CiteULike were used to test the use of inter-indexer-tagger consistency density values, revealing that the developed method is viable for a large dataset and demonstrating that vocabulary usage in a relatively new subject area like social software is no more inconsistent than the more established subject areas investigated.

Indexing Consistency and its Implications for Information Architecture : A Pilot Study

This pilot study examines inter-indexer consistency on a larger scale than other studies, discussing the challenges and potential benefits of having this diversity of indexing access points to documents and their implications for effective information architecture.

The Evidence Underlying the Cranfield Results

AN INDEXING or classification system should be judged by the retrieval results it produces, namely, the extent to which it brings forth relevant material and rejects the irrelevant. Thus,
