Residual stresses in wire-arc additive manufacturing – Hierarchy of influential variables (2020, methodology): “Two metrices, mean absolute error (MAE) [19] and correlation coefficient (R2) score [35] are used to evaluate the performance of ANN and RF models, same as Fig.”
International collaboration in science and the formation of a core group (2008, background): “Since the distributions are not expected to be normal, it has been suggested that the cosine instead of the Pearson correlation is the proper measure for normalization (Ahlgren et al., 2003; Boyack et al., 2005; cf. Hamers et al., 1989).”
Fundamentals of Information Studies: Understanding Information and Its Environment, Second Edition (2009, methodology): “Upon closer inspection of the original cocitation matrix ( Ahlgren et al., 2003 ) or of Fig. 1, we notice that these are the “hard” (Group 2) and “soft” (Group 3) retrievalists (White, 2003).”
Software survey: VOSviewer, a computer program for bibliometric mapping (2009, methodology): “Researchers for example study the effect of different similarity measures (e.g., Ahlgren et al. 2003; Klavans and Boyack 2006a; Van Eck and Waltman 2009), and they experiment with different mapping techniques (e.g., Boyack et al. 2005; Van Eck and Waltman 2007b; White 2003).”
Diversity and network coherence as indicators of interdisciplinarity: case studies in bionanoscience (2009, methodology): “Since the aim was to map the breadth of knowledge sources, similarity was measured in terms of bibliographic couplings 10 between articles (co-occurrences of references), and normalised using Salton's cosine (Ahlgren et al. 2003).”
A comparison of two techniques for bibliometric mapping: Multidimensional scaling and VOS (2010, methodology): “Nowadays, however, it is well known that the Pearson correlation has some undesirable properties (Ahlgren et al., 2003; Van Eck & Waltman, 2008).”
The resource based theory: dissemination and main trends (2006, methodology): “Much work has been done developing the theory and methodology of author co-citation analysis, firmly establishing it as a bibliometric research tool, realizing that new improvements on this methodology keep on coming out ( Ahlgren, Jarneving, and Rousseau, 2003; Chen, Cribbin, and Macredie, 2002; W”
Informetrics at the beginning of the 21st century - A review (2008, methodology): “In the recent years there has been considerable discussion on the appropriate similarity measure to be used for cocitation analysis, there are colleagues who favor Pearson’s r (White, 2003b; Bensman, 2004), and those who criticize its use (Ahlgren, Jarneving, and Rousseau, 2003).”
A review of theory and practice in scientometrics (2015, background): “In bibliometrics, Ahlgren et al. (2003) have argued convincingly in favour of the cosine as a non-parametric similarity measure because of the skewedness of the citation distributions and the abundant zeros in citation matrices.”
