The Fourth Workshop on e-Commerce and NLP (ECNLP 4)
Co-located with ACL-IJCNLP 2021 in Bangkok, Thailand, Aug 1-6, 2021
https://sites.google.com/view/ecnlp/

Workshop
========

NLP and IR have been powering e-commerce applications since the early
days of the fields. Today, NLP and IR already play a significant role
in e-commerce tasks, including product search, recommender systems,
product question answering, machine translation, sentiment analysis,
product description and review summarization, and customer review
processing, amongst many other tasks. With the exploding popularity of
chatbots and shopping assistants – both text- and voice-based – NLP,
IR, question answering, and dialogue systems research is poised to
transform e-commerce once again, but requires a forum where new and
unfinished ideas could be discussed.

Co-located with ACL 2021, the ECNLP workshop will provide a venue for
the dissemination of NLP and IR research results related to e-commerce
and online shopping, bringing together researchers from both academia
and industry. The workshop welcomes submission of late-breaking and
preliminary research results, as well as opinion and position papers.

ECNLP invites quality research contributions in different formats:
- Original long research papers (8 pages plus references and appendix)
- Original short research papers (4 pages plus references and appendix)
- Position and opinion papers (4 pages)

All submissions will undergo a double-blind review process, and
accepted submissions will be presented at the workshop either as oral
presentation or as poster.
