Modeling Scientific Impact with Topical Influence Regression

When reviewing scientific literature, it would be useful to have automatic tools that iden-tify the most influential scientific articles as well as how ideas propagate between articles. In this context, this paper introduces topical influence, a quantitative measure of the ex-tent to which an article tends to spread its topics to the articles that cite it. Given the text of the articles and their citation graph, we show how to learn a probabilistic model to re-cover both the degree of topical influence of each article and the influence relationships be-tween articles. Experimental results on cor-pora from two well-known computer science conferences are used to illustrate and validate the proposed approach.
