Monitoring geometrical properties of word embeddings for detecting the emergence of new topics.

no code implementations EMNLP 2021 Clément Christophe, Julien Velcin, Jairo Cugliari, Manel Boumghar, Philippe Suignard

Slow emerging topic detection is a task between event detection, where we aggregate behaviors of different words on short period of time, and language evolution, where we monitor their long term evolution.

How to detect novelty in textual data streams? A comparative study of existing methods

no code implementations11 Sep 2019 Clément Christophe, Julien Velcin, Jairo Cugliari, Philippe Suignard, Manel Boumghar

Since datasets with annotation for novelty at the document and/or word level are not easily available, we present a simulation framework that allows us to create different textual datasets in which we control the way novelty occurs.
