You Shall Know a User by the Company It Keeps: Dynamic Representations for Social Media Users in NLP

Understand

Information about individuals can help to better understand what they say, particularly in social media where texts are short.

• Current approaches to modelling social media users pay attention to their social connections, but exploit this information in a static way, treating all connections uniformly.
• This ignores the fact, well known in sociolinguistics, that an individual may be part of several communities which are not equally relevant in all communicative situations.
• We present a model based on Graph Attention Networks that captures this observation.
