Citation Proximity Analysis [1, 2, 3] is a method for computing similarities between academic documents developed to provide relevant literature recommendations and more precise clustering capabilities.
The approach is an advancement of co-citation analysis. In addition to the known co citation approach it considers the proximity of citations to each other within an article’s full text. The underlying idea is that the closer citations are to each other, the higher is their probability to be related.
In comparison to existing approaches, such as bibliographic coupling, co-citation analysis or keyword-based similarity computations, CPA achieves a higher precision and offers the possibility to pinpoint related sections within the text of academic documents. Moreover, CPA allows a more precise automatic document classification.
