In academic hiring, promotion, and grant evaluation, publication lists are routinely required, yet quantitative assessments of collaboration cohesion remain uncommon. This study proposes a Silhouette–Kano chart to visualize an author’s publication portfolio, using the silhouette score as coordinates (x-axis: within-cluster deviation; y-axis: between-cluster separation) and overlaying Kano’s three zones (Attractive, One-dimensional, Must-be) to classify collaboration strength as strong, medium, or weak. Based on an SCI-indexed database from the Web of Science, we analyzed the career publications of six highly productive authors. The operational rule—“Attractive region + silhouette≥0.70 = strong; on the boundary = medium; outside or Must-be = weak”—was applied. Four authors were located in the Attractive region with silhouette scores≥0.70 and were thus classified as strong. Two were classified as weak due to their authorship patterns: one produced 81% single-authored papers (138/171), and another served as a middle author in 50% of papers (291/585); their silhouette scores were 0.84 and 0.57, respectively. These findings indicate that high productivity does not necessarily indicate strong collaboration cohesion. Both the spatial location on the Silhouette–Kano chart and the author’s positional roles provide critical insights into collaborative structure. The proposed chart offers an intuitive, quantitative benchmark for assessing collaboration cohesion, and the criterion“Attractive region + silhouette≥0.70”is recommended as an operational threshold to support fairer academic evaluations in hiring, promotion, and funding decisions. |
