Language in social media is extremely dynamic:
new concepts emerge, trend and disappear,
while the meaning of existing concepts
can fluctuate over time. This work addresses
a novel task of measuring and predicting
meaning shift – context or semantic representation change from surface level dynamics e.g., word frequencies observed in social media streams. We study the relationship between language dynamics and short-term context change on a corpus of VKontakte posts
collected during the Russia-Ukraine crisis in
2014 – 2015. We train a neural network model
to predict short-term shifts in meaning from
previous meaning as well as word dynamics.
We demonstrate that short-term representation
shift can be accurately predicted up to several
weeks in advance. Moreover, we visualize this
short-term context shift for the example words
and demonstrate the practical side of our approach to discover and track meaning of newly emerging terms in social media during crises.
