Augmenting BERT-style Models with Predictive Coding to Improve Discourse-level Representations

no code implementations10 Sep 2021 Vladimir Araujo, Andrés Villa, Marcelo Mendoza, Marie-Francine Moens, Alvaro Soto

Current language models are usually trained using a self-supervised scheme, where the main focus is learning representations at the word or sentence level.

Neural Abstractive Unsupervised Summarization of Online News Discussions

1 code implementation7 Jun 2021 Ignacio Tampe Palma, Marcelo Mendoza, Evangelos Milios

Our novel approach provides a summary that represents the most relevant aspects of a news item that users comment on, incorporating the social context as a source of information to summarize texts in online social networks.

A data-driven strategy to combine word embeddings in information retrieval

no code implementations26 May 2021 Alfredo Silva, Marcelo Mendoza

We use Idf combinations of embeddings to represent queries, showing that these representations outperform the average word embeddings recently proposed in the literature.

Ad-Hoc Information Retrieval Information Retrieval +1

Tracking the progress of Language Models by extracting their underlying Knowledge Graphs

no code implementations1 Jan 2021 Carlos Aspillaga, Marcelo Mendoza, Alvaro Soto

The state of the art, previously dominated by pre-trained word embeddings, is now being pushed forward by large pre-trained contextual representation models.
