2019 - the year of anniversaries: Time to reflect and look ahead.
- 30th Anniversary of the fall of the Berlin Wall
- 30th Hypertext Conference
- 30th Anniversary of the WWW
- 20th Anniversary of the first ACM Hypertext Conference in Germany


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.

The theme of Hypertext 2019 is "HYPERTEXT - TEAR DOWN THE WALL". This motto of the 30th ACM Hypertext conference goes hand in hand with the 30th anniversary of the fall of the Berlin Wall. Inspired by the historical events in Germany, Hypertext 2019 aims at reunifying different hypertext research directions and communities. Therefore, apart from the regular research tracks, Hypertext 2019 will feature a research track on 30 Years Hypertext as well as an exhibition/creative track. 2019 will also be the 30th anniversary of the WWW. It is a perfect time to join in, reflect our common roots, and discuss how we can jointly address our current and future challenges.

The conference will take place at the Institute of Information Systems (iisys) at Hof University, Germany. Hof lies midway between Frankfurt and Prague, Munich and Berlin and is very close to the former German-German border, in particular to the village of Mödlareuth, called "little Berlin", which used to be divided by a wall. After exactly 20 years, Hypertext 2019 will take place in Germany again for the 2nd time.

Hypertext 2019 is co-locating with the Adaptivity and User Modeling Workshop (ABIS'19), taking place on Sep 16 at Hof University, and with ACM Document Engineering Conference (DocEng'19) organized in Berlin, Germany, between Sep 23-16.

We invite submissions of a broad range of research focusing on reflections on or retrospectives of hypertext approaches and systems. Those should focus on "forgotten" issues, beneficial features, system behavior, or theories that were discovered, but are ignored by current systems. Contributions should be visionary and discuss those old ideas with a strong focus on today's information systems; they should conclude where and to which extent previously discovered ideas would enhance our current or future applications.



Chair: Ujwal Gadiraju, L3S Research Center, Germany (@UjLaw - https://twitter.com/UjLaw)

Posters and demos will be presented during the conference. They target research and showcases in the above mentioned areas.


Chair: Mark Bernstein, Eastgate Systems, Inc., USA (@eastgate - https://twitter.com/eastgate)
Curator: Dene Grigar, Washington State University Vancouver, USA (@dgrigar - https://twitter.com/dgrigar)

The conference will include a creative track and exhibition, with readings and performances, workshops, demonstrations of both novel and historical systems, and innovative new work in electronic art and literature.

For the creative track, we invite submissions from all disciplines that engage with the expressive potential of hypertext, the link, and of social media-particularly those that address the conference theme of "tear down the wall".

The curated exhibition seeks hypertextual works of any length that explore new artistic forms, or that respond to or engage with older electronic literature. We are especially interested in location-aware and locative work that can be read in or near the conference site. We are open to work on any platform. Questions regarding creative work for the exhibition may be addressed to the curator.

Limited travel funds and bursaries may be available, as well as assistance and support for installation on site. Proposals for papers, panels, master-classes, workshops, and creative work for the exhibition should be submitted by 19 May 2019.


Chair: Ethan Munson, University of Wisconsin Milwaukee, USA

Originality of Submissions
Submissions must represent new and original work. Concurrent submissions are not allowed. Papers that have been published in or accepted to any peer-reviewed journal or conference/workshop with published proceedings, are currently under review, or will be submitted to other meetings or publications while under review for WSDM 2017 may not be submitted to WSDM 2017.  We allow submissions that have been previously presented as posters, or in venues with no formal proceedings, but this must be indicated on the first page of the submission. Additionally, the ACM has a strict policy against plagiarism and self-plagiarism. All prior work must be appropriately cited.

Submission Process
Papers must be submitted in PDF format according to ACM guidelines and style files to fit within 8 pages including any diagrams and appendices, plus up to 1 additional page of references. PDF files must have all non-standard fonts embedded. Submissions must be self-contained and in English.  After uploading your submission, please check the copy stored on the site. Submissions that do not follow these guidelines, or do not view or print properly, may be rejected without review.

PDF files submitted to WSDM 2017 must be anonymized:  the submitted document should not include author or affiliation information, and should not include citations or discussion of related work that would make the authorship obvious.

To support identification of reviewers with conflicts of interest, the full author list must be specified at submission time. In exceptional cases, the author list may be modified later with permission of the PC Chairs.

Review Process
Each paper will be reviewed by at least three PC members and a senior PC member. The acceptance decisions will take into account paper novelty, technical depth, elegance, practical or theoretic impact, and presentation. As an experiment this year, WSDM 2017 will use a combination of single-blind reviewing and double-blind reviewing.

Please contact the PC chairs at the address below for any questions on the submission or review process.

The algorithms, resources and methods used within a paper should be described as completely as possible.  Authors may reference supplementary material, including detailed descriptions, test datasets or code.  However, this information is not part of the submission proper, and will be read only at the discretion of the reviewers.  Wherever appropriate, the authors are encouraged to use publicly available test collections and state-of-the-art baselines.  Please consider sharing your intermediate/final experimental results and code with the research community.

Publication and Presentation
All accepted papers will be published in the ACM Digital Library. For every paper there must be a registered author to present it in person at WSDM 2017. At the conference, each paper will be allocated a slot at the interactive poster session to encourage discussion. Additionally, selected papers will be presented during the plenary oral sessions as either long or short talks.

AUTHORS TAKE NOTE: The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of your conference. The official publication date may affect the deadline for any patent filings related to published work.
