"Bibliometrics", "scientometrics", "informetrics", and "webometrics" can all
be considered as manifestations of a single research area with similar
objectives and methods, which we call "information metrics" or iMetrics. This
study explores the cognitive and social distinctness of iMetrics with respect
to the general information science (IS), focusing on a core of researchers,
shared vocabulary and literature/knowledge base. Our analysis investigates the
similarities and differences between four document sets. The document sets are
drawn from three core journals for iMetrics research (Scientometrics, Journal
of the American Society for Information Science and Technology, and Journal of
Informetrics). We split JASIST into document sets containing iMetrics and
general IS articles. The volume of publications in this representation of the
specialty has increased rapidly during the last decade. A core of researchers
that predominantly focus on iMetrics topics can thus be identified. This core
group has developed a shared vocabulary as exhibited in high similarity of
title words and one that shares a knowledge base. The research front of this
field moves faster than the research front of information science in general,
bringing it closer to Price's dream.Comment: Accepted for publication in Scientometric
