Research on the Semantic Measurement in Co-word Analysis
2018Aiming at problems of the “same amount with different qualities’’ phenomenon and the lack of semantics in co-occurring terms, this paper proposed a new semantic measurement method in co-word analysis. The method firstly gave different weights to document units based on the Pointwise Mutual Information (PMI) method, and then extended them to the ...

The co-word problem for the Higman-Thompson group is context-free
Bulletin of the London Mathematical Society, 2007Summary: The co-word problem of a group \(G\) generated by a set \(X\) is defined as the set of words in \(X\) which do not represent 1 in \(G\). We introduce a new method to show that a permutation group has context-free co-word problem. This method is used to show that the Higman-Thompson groups, and therefore the Houghton groups, have context-free ...

Mapping 20 years of accessibility research in HCI: A co-word analysis
International Journal of Human-Computer Studies, 2023We employ hierarchical clustering, strategic diagrams, and network core-periphery analysis to assess and visualise the intellectual progress of accessibility research within HCI in the past two decades. The study quantifies and explains the development of accessibility research and its thematic evolution based on 1,535 papers published at TACCESS ...

Ranking of field association terms using Co-word analysis
Information Processing & Management, 2008Information retrieval involves finding some desired information in a store of information or a database. In this paper, Co-word analysis will be used to achieve a ranking of a selected sample of FA terms. Based on this ranking a better arranging of search results can be achieved.

Mapping co-word structures: A comparison of multidimensional scaling and leximappe
Scientometrics, 1989The LEXIMAPPE method and Multidimensional Scaling (MDS) are discussed as methods to visualize (‘map’) characteristics of structures of word-occurrence (‘co-word’) relations. Utilization of MDS is proposed as an alternative mapping method able to circumvent problematic features of LEXIMAPPE maps of the total co-word structure.

Why words and co‐words cannot map the development of the sciences
Journal of the American Society for Information Science, 1997A restricted set of full-text articles from a sub-specialty of biochemistry was analyzed and compared in terms of co-occurrences and co-absences of words. By using the distribution of words over the sections, a clear distinction among theoretical observational, and methodological terminology can be made in individual articles.
