Webpage information extraction (WIE) is an important step to create knowledge bases. For this, classical WIE methods leverage the Document Object Model (DOM) tree of a website. However, use of the DOM tree poses significant challenges as context and appearance are encoded in an abstract manner. To address this challenge we propose to reformulate WIE as a context-aware Webpage Object Detection task. Specifically, we develop a Context-aware Visual Attention-based (CoVA) detection pipeline which combines appearance features with syntactical structure from the DOM tree. To study the approach we collect a new large-scale datase of e-commerce websites for which we manually annotate every web element with four labels: product price, product title, product image and others. On this dataset we show that the proposed CoVA approach is a new challenging baseline which improves upon prior state-of-the-art methods.

 **Description:** NLP and IR have been closely linked to e-commerce applications since the early days of the fields. This close relationship
between the two is evidenced by early publications as well as the growing number of recent publications at the intersection
of the two areas. Today, NLP and IR play a significant role in e-commerce tasks, including product search, recommender
systems, product question answering, sentiment analysis, product description and review summarization, chatbots and
shopping assistants, and customer review processing, among many other tasks being investigated by researchers in the
field. These methods play a key part in today’s online retail and shopping landscape, and continue to evolve and further
enhance the customer experience. The ECNLP workshop aims to provide a venue for the dissemination of NLP/IR
research related to e-commerce and online shopping, bringing together researchers from both academia and industry.

# 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!
