This study presents a historical overview of the International Conference on Human Robot Interaction (HRI). It summarizes its growth, internationalization and collaboration. Rankings for countries, organizations and authors are provided. Furthermore, an analysis of the military funding for HRI papers is performed. Approximately 20% of the papers are funded by the US Military. The proportion of papers from the US is around 65% and the dominant role of the US is only challenged by the strong position of Japan, in particular by the contributions by ATR.
Collaboration between researchers and between research organizations is generally considered a desirable course of action,
in particular by some funding bodies. However, collaboration within a multidisciplinary community, such as the Computer–Human
Interaction (CHI) community, can be challenging. We performed a bibliometric analysis of the CHI conference proceedings to
determine if papers that have authors from different organization or countries receive more citations than papers that are
authored by members of the same organization. There was no significant difference between these three groups, indicating that
there is no advantage for collaboration in terms of citation frequency. Furthermore, we tested if papers written by authors
from different organizations or countries receive more best paper awards or at least award nominations. Papers from only one
organization received significantly fewer nominations than collaborative papers.
The h-index has received an enormous attention for being an indicator that measures the quality of researchers and organizations. We investigate to what degree authors can inflate their h-index through strategic self-citations with the help of a simulation. We extended Burrell's publication model with a procedure for placing self-citations, following three different strategies: random self-citation, recent self-citations and h-manipulating self-citations. The results show that authors can considerably inflate their h-index through self-citations. We propose the q-index as an indicator for how strategically an author has placed self-citations, and which serves as a tool to detect possible manipulation of the h-index. The results also show that the best strategy for an high h-index is publishing papers that are highly cited by others. The productivity has also a positive effect on the h-index.
