Abstract

Entity Linking is the task of automatically identifying entity mentions in a piece of text and linking them to their corresponding entries in a reference knowledge base like Wikipedia. Although there is a plethora of works on entity linking, existing state-of-the-art approaches do not explicitly consider the time aspect and specifically the temporality of an entity’s prior probability (popularity) and embedding (semantic network). Consequently, they show limited performance in annotating old documents like news or web archives, while the problem is bigger in cases of short texts with limited context, such as archives of social media posts and query logs. This thesis focuses on this problem and proposes a modeling that leverages time-aware prior probabilities and word embeddings in the entity linking task
