32nd ACM Conference on Hypertext and Social Media (HT’21)

Hosted by: Trinity College Dublin, Ireland


The ACM Hypertext conference is a premium venue for high quality peer-reviewed research on hypertext theory, systems and applications. It is concerned with all aspects of modern hypertext research including social media, semantic web, dynamic and computed hypertext and hypermedia as well as narrative systems and applications. Hypertext 2021 (HT’21) on the theme “Hypertext in a Multimodal World” will be a hybrid event taking place in Dublin, Ireland, and with online participation. More details will become available soon, so watch this space. Conference tracks to be announced soon!

The theme of Hypertext 2021 is "Hypertext in a Multimodal World". The hypertext paradigm has transformed the way we store and transfer knowledge and how we think about information and access it. We access the same sources via multiple devices, ranging from smart watches and smart phones to laptops. Information and transactions become ever more visual, with video increasingly replacing traditional text-based web pages. Particularly, we use interactive hypertext, news feeds and videos for getting things done: planning a trip, managing our finances, interacting with colleagues, friends and family, being productive and creative.

At Hypertext 2021, we aim to further discuss, reflect, investigate and look forward on all of these developments, from the mixed perspectives of technology, users and society. What trends can be observed? What societal issues arise or can now be investigated? How can the user experience be further improved? What alternative, creative and fun novel applications does Hypertext enable and facilitate?

We welcome the following types of submissions:

Conference Main Tracks

Adaptive Web and Recommender Systems

Track Chair: Denis Helic (TU Graz, Austria)

The Adaptive Web and Recommendation Systems track invites submissions focused on the interaction between (social) recommendation and knowledge transfer, for example in personalized news feeds, wikis, multimedia narratives, but also for non-linear teaching and learning. Contributions may focus on empirical analysis of user interactions with personalized Web systems to improve our understanding of individual and collective user behavior, explore novel user models and novel recommendation and personalization algorithms, or focus on understanding of mutual interdependence between user behavior and algorithms.

Topics include but are not limited to:

Social Web

Track Chair: Luca Maria Aiello (Nokia Bell Labs, UK)
Twitter: @lajello

The Social Web track invites work in the areas of data science and computational social science aimed at investigating the role of the Web in shaping social processes that impact online or offline societal outcomes. Contributions may focus on studying behavior, norms, and psychological perceptions that characterize Web-mediated social interactions and might help either limiting undesirable outcomes (e.g., conflict, hate speech, misinformation) or promoting positive social dynamics (e.g., cooperation, integration, support, knowledge diffusion). Contributions focusing on multimodal social interactions (i.e., not limited to text) are particularly welcome.

Topics include but are not limited to:

Semantic Web and NLP

Track Chair: Marieke van Erp (KNAW Humanities Cluster, the Netherlands)
Twitter: @merpeltje

Hypertext and the WWW form an intricate interplay of semi- or unstructured textual data and structured data. To make sense of this, both natural language processing and semantic web techniques are required. In this track, we invite submissions that address the interpretation of hypertext and WWW content through the lens of these two disciplines. Related to the main conference theme ‘Hypertext in a Multi-Modal World’ we specifically invite contributions that address multisensory information from an NLP or semantic web perspective (e.g. work that explores the relationship between text and images and/or other modalities and how to model these).

Topics include but are not limited to:

Human-information interaction, search and retrieval

Track Chair: Jacek Gwizdka (University of Texas at Austin, USA)

The human-information interaction, search and retrieval track invites submissions focused on user-centered approaches to the design and evaluation of hypertext systems for information access, retrieval, and use. Contributions may explore improvements to existing hypertext systems, propose novel models, and systems, or focus on understanding individual and group interactions with hypertext information systems.

Topics covered include but are not limited to:

Digital Humanities, Games, and Culture

Track Chair: Anastasia Salter (University of Central Florida, USA)
Twitter: @anasalter

The Digital Humanities and Culture track invites explorations of hypertext as a creative tool, shaping literature, culture, and play. Contributions may explore the humanist impact of hypertext systems; cultural works engaging with novel uses of hypertext systems; and digital humanities research driven by changing platforms.

Topics include but are not limited to:
