Workshop on

Intelligent Interactive Systems and Language Generation

Including language promises to bring more natural interaction for the user with intelligent interactive systems (2IS). Current maturity in Natural Language Generation (NLG) is facilitating the use of NLG components, and bringing clear opportunities for further development. For example, conversational interaction and interfaces are nowadays a trend, showing the central role of language generation in a variety of intelligent interactive systems.

Nevertheless, embedding language generation may not be a straightforward issue because it is not just about words, but also considering multi-modal aspects in the interactive system to provide a more intelligent generation. Every context of use may have different requirements —requiring personalization or adaptation of services—, and the purpose or the different characteristics and modalities of the interfaces employed can altogether affect the effective integration of NLG services.

In order to define research challenges and raise a constructive discussion from an interdisciplinary perspective, this workshop seeks to gather researchers and practitioners working on language generation, human-computer interaction, conversational agents, and computational intelligence that deal with cross-cutting issues concerning language generation and intelligent interactive systems.

The workshop will be held as part of the International Conference on Natural Language Generation (INLG2018), which is supported by the Special Interest Group on NLG of the Association for Computational Linguistics. INLG 2018 is to be held in Tilburg (The Netherlands), 5-8 November, 2018.

General aims

  • Identify challenges and explore potential transfer opportunities between fields, generating synergy and symbiotic collaborations in the context of Intelligent Interactive Systems and Language Generation
  • Strengthen the network of researchers and practitioners interested in taking NLG further to enable the next generation of intelligent interactive systems
  • Establish the identified challenges in a concrete research agenda to be addressed in future international collaborative actions (e.g. more specialized workshops, projects, publications, networks of excellence)

Invited speaker

We are honoured to host an invited talk by Sander Wubben, who will discuss the lastest advances and current limitations of chatbots and voice apps in his talk “Applications of NLG in practical conversational AI settings”. He is an assistant professor at Tilburg University and co-founder of, committed to bring smarter interactive chatbots as a form of conversational AI.

How to participate

We solicit researchers for contributions dealing with language generation issues in relationship with any of the many aspects concerned with intelligent interactive systems. The list of topics below exemplifies some possible themes, in which either interaction or artificial intelligence is addressed jointly with language generation.

It will be possible to submit regular papers (up to 4 pages + 1 references) and demo papers (up to 2 pages). Papers should follow the ACL paper format. The contributions will be subject to a blind peer review process to assess their relevance and originality for the workshop. Accepted contributions will be the primary input source for the workshop and authors will be requested to present their contributions in either a poster or presentation, considering the most suitable format in each case.

Non-academic participants from the industry are very welcome to share their valuable experiences, preferably in the form of demo papers. Contributions will be compiled in companion proceedings to be published in ACL Anthology.

Submissions should be made through easychair here.
