Our analysis indicates that co-occurring concept pairs tend to be spread across two extremesthose with high growth in publications over the last few years but an overall low number of publications and those with relatively slower growth in publications but an overall higher number of publications. The former represent potentially emerging concept pairs while the latter represent concept pairs that are perhaps better studied/reported and identifying both types of emerging concept pairs have merit. Our focus was limited to the following four concept pairs: biomarkers and cancer type, therapeutic targets and cancer type, therapeutic targets and therapy types, and therapy and cancer types. While we performed co-occurrence analysis for both criteria -cooccurrence of terms in sentence and in abstract, we chose to prioritize the in-sentence cooccurrence as it was much less likely to result from coincidence and implied a stronger relationship between the terms. Continued refinement and development of analytical methods such as these are important to identify emerging concepts in various fields. We hope our results from this study in conjunction with our previously published results can provide insights into the highly interconnected and complex landscape of immuno-oncology.
