Researchers may describe different aspects of past scientific publications intheir publications and the descriptions may keep changing in the evolution ofscience. The diverse and changing descriptions (i.e., citation context) on apublication characterize the impact and contributions of the past publication.In this article, we aim to provide an approach to understanding the changingand complex roles of a publication characterized by its citation context. Wedescribed a method to represent the publications' dynamic roles in sciencecommunity in different periods as a sequence of vectors by training temporalembedding models. The temporal representations can be used to quantify how muchthe roles of publications changed and interpret how they changed. Our study inthe biomedical domain shows that our metric on the changes of publications'roles is stable over time at the population level but significantly distinguishindividuals. We also show the interpretability of our methods by a concreteexample.
