GROUPS WITH INDEXED CO-WORD PROBLEM
International Journal of Algebra and Computation, 2006We investigate co-indexed groups, that is groups whose co-word problem (all words defining nontrivial elements) is an indexed language. We show that all Higman–Thompson groups and a large class of tree automorphism groups defined by finite automata are co-indexed groups.

Hypothesis generation guided by co-word clustering
Scientometrics, 2003Co-word analysis was applied to keywords assigned to MEDLINE documents contained in sets of complementary but disjoint literatures. In strategical diagrams of disjoint literatures, based on internal density and external centrality of keyword-containing clusters, intermediate terms (linking the disjoint partners) were found in regions of below-median ...

Research on the semantic-based co-word analysis
Scientometrics, 2011Through analysis of problems of keywords and indexes used in co-word analysis, we find that the key to solving these problems is to integrate experts' knowledge into co-word analysis. Therefore, this paper proposes a new co-word analysis: semantic-based co-word analysis which can integrate experts' knowledge into co-word analysis effectively.

A Co-Word Study of Artificial Intelligence
Social Studies of Science, 1989This Note briefly describes the method of `co-word analysis', and presents some results of its application to the scientific literature in the field of Artificial Intelligence (AI). A sample of AI literature, published in 1984 and 1985, was drawn from the CNRS/INIST database in Paris.

A co-word analysis of library and information science in China
Scientometrics, 2013This study aims to reveal the intellectual structure of Library and Information Science (LIS) in China during the period 2008---2012 utilizing co-word analysis. The status and trends of LIS in China are achieved by measuring the correlation coefficient of selected keywords extracted from relevant journals in the Chinese Journal Full-Text Database.

Mapping acidification research: A test of the co-word method
Scientometrics, 1992This paper extends the co-word method for mapping science, adopting new statistical and graphical methods to explore time-series data and the changing distribution of effort between different research themes. It also tests the reliability of the co-word method, comparing coword data on the acidification of the environment with data derived from a large
