Phrase representations play an important role in data science and natural language processing, benefiting various tasks like Entity Alignment, Record Linkage, Fuzzy Joins, and Paraphrase Classification.
The current state-of-the-art method involves fine-tuning pre-trained language models for phrasal embeddings using contrastive learning. However, we have identified areas for improvement. First, these pre-trained models tend to be unnecessarily complex and require to be pre-trained on a corpus with context sentences.
Second, leveraging the phrase type and morphology gives phrase representations that are both more precise and more flexible.
We propose an improved framework to learn phrase representations in a context-free fashion.
The framework employs phrase type classification as an auxiliary task and incorporates character-level information more effectively into the phrase representation.
Furthermore, we design three granularities of data augmentation to increase the diversity of training samples.
Our experiments across a wide range of tasks reveal that our approach generates superior phrase embeddings compared to previous methods while requiring a smaller model size.

Learning High-Quality and General-Purpose Phrase Representations

State-of-the-art NLP systems represent inputs
with word embeddings, but these are brittle
when faced with Out-of-Vocabulary (OOV)
words. To address this issue, we follow
the principle of mimick-like models to generate vectors for unseen words, by learning
the behavior of pre-trained embeddings using only the surface form of words. We
present a simple contrastive learning framework, LOVE, which extends the word representation of an existing pre-trained language
model (such as BERT), and makes it robust to OOV with few additional parameters.
Extensive evaluations demonstrate that our
lightweight model achieves similar or even better performances than prior competitors, both
on original datasets and on corrupted variants.
Moreover, it can be used in a plug-and-play
fashion with FastText and BERT, where it significantly improves their robustness.

Welcome to the 18th Conference of the European Chapter of the Association for Computational Linguistics (EACL). Continuing its mission of expanding and involving the science community of all European countries, EACL has selected the Malta community for the 18th EACL. Considering the importance of physical interaction among researchers, the conference will be held at the Hotel Radisson Blu, St. Julians, in Malta, from 17 to 22 of March, 2024. The conference will also feature the possibility to participate virtually. As the flagship European conference in the field of computational linguistics, EACL welcomes European and international researchers covering a broad spectrum of research areas that are concerned with computational approaches to natural language.

# Welcome everyone to ACL 2022!

The 60th Annual Meeting of the Association for Computational Linguistics is taking place May 22-27, 2022 as a hybrid event, in Dublin and online. We are happy to welcome all of you to this anniversary edition with an almost 50-50 in-person and virtual participation. 
The main conference program features oral presentations, in-person and virtual posters and demo sessions, a plenary session for our best paper presentations and awards, three amazing keynote events and two new initiatives of invited talks: Spotlight Talks for Young Rising Stars (STIRS) and The Next Big Idea Talks. Posters (including Findings of ACL 2022) and demos are grouped by areas for both the in-person and the virtual sessions. For the virtual component, the talks will be on Zoom and the posters and the demos will be in GatherTown. The Student Research Workshop will have an oral session and a poster session as part of Poster Session 1. The program also features eight Tutorials and 28 Workshops. 

 
We wish you a wonderful conference!
