Gaël Poux-Médard, Julien Velcin, Sabine Loudcher
The textual content of a document and its publication date are intertwined. For example, the publication of a news article on a topic is influenced by previous publications on simi…
Monitoring geometrical properties of word embeddings for detecting the emergence of new topics
Clément Christophe, Julien Velcin, Jairo Cugliari +2
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 t…
Link Prediction with Mutual Attention for Text-Attributed Networks
Robin Brochier, Adrien Guille, Julien Velcin
In this extended abstract, we present an algorithm that learns a similarity measure between documents from the network topology of a structured corpus. We leverage the Scaled Dot-P…
Global Vectors for Node Representations
Robin Brochier, Adrien Guille, Julien Velcin
Most network embedding algorithms consist in measuring co-occurrences of nodes via random walks then learning the embeddings using Skip-Gram with Negative Sampling. While it has pr…
Automatic Language Identification for Romance Languages using Stop Words and Diacritics
Ciprian-Octavian Truică, Julien Velcin, Alexandru Boicea
Automatic language identification is a natural language processing problem that tries to determine the natural language of a given content. In this paper we present a statistical m…
