General & ProgramChairs’ WelcomeIt is our great pleasure to welcome you to the 30th Anniversary ACM Conference on Hypertext and Social Media at Hof University, Germany, on September 17–20, 2019.

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

30 Years of 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 ACM Document Engineering

Conference (DocEng’19) organized in

Berlin, Germany, between September

23–16. This year the ACM Hypertext

conference attracted 103 submissions

to the five main technical tracks,

these were split approximately half on

traditional Hypertext topics, and half on

Social Media research, showing both

the longevity and continued relevance

of hypertext and social systems to the

challenges of today’s digital world. Our

PC worked hard to produce over 300

reviews in a short time period, and in

total we accepted 30 technical papers

(a 29% acceptance rate) which reflects

the high quality of submissions that we

received.

We are especially pleased to have

been able to accept 9 papers in the

area of Literature, Games and Digital

Humanities. This has always been a

vibrant area of research and together

with the creative track is an important

part of what has always made the ACM

Hypertext conference series special.

6 WELCOME

Together with an additional 17 poster acceptances,

across topics as varied as Privacy, Toxicity, and

Historiography, we have around 40 different countries

represented at ACM Hypertext, which shows the good

health and widespread appeal of this community and

guarantees a vibrant conference event.

We would like to thank all people who volunteered for

making this conference a success. In particular, we would

like to thank the various chairs who spent a tremendous

amount of time to manage the various tasks at hand.

A special “thank you” goes to all of you who joined in as

attendees, presenters, or those who submitted a paper

(whether accepted or not). We appreciate very much your

statement that you care about this community. The fact

that you come from various research fields shows our idea

of reunification to be successful. Last but not least, we

would like to thank our sponsors and supporters: ACM,

SIGWEB, Hof University, Institute of Information Systems

(iisys), the Electronic Literature Organization (ELO), and

the Hypertext Steering Committee for their great support,

which was needed to conduct an anniversary conference

appropriately and successfully.

We hope that this anniversary helps in strengthening

and extending the interdisciplinary hypertext community.

It is worth looking at our long and joint history to carve a

future in which hypertext ideas and paradigms take an

influential role in addressing our societal challenges.

We hope to see you (again) at future ACM Hypertext

conferences. On behalf of all chairs, thank you for your

interest and support.

7WELCOME

Dear guests at Hof University: “Tear

Down the Wall” – this motto was chosen

for the 30th Hypertext Conference, on

the 30th anniversary of the fall of the

Berlin Wall, for a good reason.

Only in a few regions in Germany the

significance of this motto is as relevant

as it is in Hof. Formerly located next to

the Iron Curtain (the border that divided

the eastern and western world), Hof is

now in the heart of Europe. With the

fall of the Berlin wall in November 1989

the region experienced how liberating

it is to overcome borders. Where there

used to be walls and fences, there was

suddenly boundless freedom.

Another anniversary is celebrated

in 2019: the 30th birthday of the World

Wide Web. Communication and

cooperation also overcame borders and

opens up completely new, seemingly

boundless freedoms. This rapidly

changes the world much beyond the

fall of the Iron Curtain. For the ACM

Hypertext Conference, “Tear Down the

Wall” refers to a very broad spectrum

of topics, including artistic impulses

from the field of electronic literature.

It is good to see that researchers

from various fields joining together

toward reaching higher goals. I am

very pleased that so many of you have

accepted the invitation to attend this

anniversary ACM Hypertext Conference

at the Institute of Information Systems

at Hof University. I wish the conference

every success and many new insights

for all of you “beyond the wall”.

Greetings from the President of Hof University Prof. Dr. Dr. h.c. Jürgen Lehmann

ABIS/ G023b

23rd International Workshop on Personalization and Recommen-dation on the Web and Beyond

ABIS 2019 is an international workshop, organized by

the SIG on Adaptivity and User Modeling of the German

Gesellschaft für Informatik. For more than 20 years, the

ABIS Workshop has been a highly interactive forum for

discussing the state of the art in personalization and user

modeling. Latest developments in industry and research

are presented in plenary sessions, forums, and tutorials.

For the first time, ABIS will be hosted by the ACM Inter-

national Conference on Hypertext and Social Media

(HT'19), which will celebrate its 30th anniversary this year.

ABIS 2019 additionally features the introduction of the

new book on Personalized Human-Computer Interaction,

edited by the workshop chairs and to be published in 2019

by DeGruyter.

ABIS is a Special Interest Group of the German Gesell-

schaft für Informatik (GI e.V.) within the sections Artificial

Intelligence (FBKI) and Human Computer Interaction (MCI).

Our aim is to foster research in the area of adaptive

systems. We are open to all who are interested in the field

and specifically encourage students to join and make use

of the expertise in our community. Members from outside

Germany are welcome as well.

International Workshop On Job Knowledge Discovery on the Web & Social Media.

We plan to have invited keynote talks from academia and

industry (one each) that focus on the interdisciplinary

nature of. We will have paper presentations of selected

papers after peer-reviews. Each paper will receive at least

3 reviews. Finally, we will have a moderated discussion to

assimilate the most important challenges to overcome

while using large-scale web data-driven solutions for

job knowledge discovery and conducting labor market

analysis in an ever-changing population landscape.

SIdEWays / G128

Social media services represent freely-accessible social

networks allowing registered members to broadcast short

posts referring to a potentially-unlimited range of topics,

by also exploiting the immediateness of handy smart

devices. This workshop wants to stress the vision of this

powerful communication channel as social sensor, which

can be used to detect and characterize interesting and yet

unreported information and events in real time, crossing

all topics and locations. Future technologies on this

connectivity may also provide applications with automatic

techniques for the generation of news (filtered over user

profiles), offering a sideways to the existing authoritative

information media.

HUMAN/ G111

HUMAN’19 is the second workshop of a new series for

the ACM Hypertext conferences. It has a strong focus

on the user and thus is complementary to the strong

machine analytics research direction that could be

experienced in previous conferences.

The user-centric view on hypertext not only includes

user interfaces and interaction, but also discussions

about hypertext application domains. Furthermore, the

workshop raises the question of how original hyper-

text ideas (e.g., Doug Engelbart’s “augmenting human

intellect” or Frank Halasz’ “hypertext as a medium for

thinking and communication”) can improve today’s

hypertext systems.

Recent hypertext research is strongly focused on

machine analytics. We would like to broaden the scope

again to include more research on human factors.

Historically, hypertext research is strongly connected

with human factors. Hypertext pioneers, such as Doug

Engelbart or Ted Nelson, focused on human factors in

hypertext, e.g., Doug Engelbart’s “aug-

menting human intellect” or Ted Nelson’s

information structure “ZigZag”. This

workshop combines original hypertext

research ideas with recent hypertext re-

search trends. In addition, the motivation

is to consolidate different hypertext re-

search areas from the viewpoint of human

factors. If you tweet about the workshop

please use #HUMAN19.

Tutorial ML/ G128

Hands on advanced machine learning for information extraction from tweets tasks, data, and open source tools.

Information extraction (IE) is a

common sub-area of natural language

processing that focuses on identifying

structured data from unstructured

data. One example of IE is to identify

named entities in a text, e.g., "Barack

Obama served as the president of the

USA". Here, Barack Obama and USA

are named entities of types of PERSON

and LOCATION, respectively. Another

example is to identify sentiment

expressed in a text, e.g., "This movie

was awesome". Here, the sentiment

expressed is positive. Finally, identifying

various linguistic aspects of a text, e.g.,

part of speech tags, noun phrases,

dependency parses, etc., which can

serve as features for additional IE tasks.

This tutorial introduces participants

to the usage of Python based, open

source tools that support IE from

social media data (mainly Twitter),

and best practices for ensuring the

reproducibility of research.

Participants will learn and practice

various semantic and syntactic IE

techniques that are commonly used

for analyzing tweets. Additionally,

participants will be familiarized with the

landscape of publicly available tweet

data, and methods for collecting and

preparing them for analysis. Finally,

participants will be trained to use a suite

of open source tools (SAIL for active

learning, TwitterNER for named entity

recognition, and SocialMediaIE for multi

task learning), which utilize advanced

machine learning techniques (e.g., deep

learning, active learning with human-

in-the-loop, and multi-task learning)

to perform IE on their own or existing

datasets. The tools introduced in the

tutorial will focus on the three main

stages of IE, namely, collection of data

(including annotation), data processing

and analytics, and visualization of the

extracted information.

This workshop aims to provide an

interdisciplinary forum to bring together

individuals from the humanities and

technological communities to share

work and discuss state-of-the-art

research on narrative from both a

technical and aesthetic perspective. It

is part of the longest running workshop

series at ACM Hypertext – running

since 2011 – and has fostered numerous

collaborations which have led to work

published in the main conference

as well as serving as an important

discussion point for important issues

facing the community. NHT has

worked hard to serve as a focus point

for the wider narrative and hypertext

community and through NHT’s new

sister workshop AIS the intention is

for this workshop to act as a bridge to

increase collaboration between the

interactive narrative and hypertext

research communities.

This year’s workshop will build upon

these previous successes, and aims to

continue to consolidate this community

by providing an open interdisciplinary

forum of discussion on key issues

facing the field.

This year in particular NHT seeks to

mirror HT’19’s theme of “reunification”

and to assist in the conference’s aim

to bring back diverse aspects of the

historical ACM Hypertext research

community. NHT is, thematically, best

served to deliver this through the

Narrative and Hypertext community and

it has already been working towards this

twinning with a sister conference in AIS

at the interactive narrative conference

ICIDS. Furthermore NHT this year

plans to strengthen the pull on this

community and support this relationship

by working closely with the return of the

ACM Hypertext Creative track. To this

end we plan to dedicate a portion of the

workshop to discussion of the hypertext

narrative works in the creative track.

Hyperfiction Exhibition.

Dene Grigar.

A locative hyperfiction is a story

read on your smartphone. You

navigate and make choices by

walking to new locations, triggering

new parts of the story to read.

The Dean of Liminal Studies is

deployed on the StoryPlaces

locative hypertext system

(storyplaces.soton.ac.uk), an open

source tool that allows people to

create and read locative stories.

StoryPlaces stories do not require

an app, and can be read on any

modern smartphone with location

services (GPS) via a Web browser.

Just make sure you enable

location sensing when asked!

28 KEYNOTE SPEAKER

Belinda BarnetKeynote SpeakerNavigation is impossible unless you remember

where you’ve been. As we steer full tilt into a hori-

zon line of machine learning, social media, and

data analytics, it is time to take our bearings.

This is the 30th ACM Hypertext conference,

and with that in mind, I’ve decided to gather some

memories together from hypertext pioneers

about the early vision of those first conferences

three decades ago. Where have we been?

Belinda Barnet is Senior Lecturer in

Media at Swinburne University, Aus-

tralia. She is the author of “Memory

Machines: the Evolution of Hypertext”

(Anthem Press UK, 2013 & 2015). She

convenes the Social Media Major at

Swinburne.

29KEYNOTE SPEAKER

2019 marks not only the 30th anniversary of the falling

of the Berlin Wall, but also the 50th anniversaries of

equally momentous events of 1968–1969 in the US and

elsewhere. Martin Luther King and Robert Kennedy

were assassinated. Hippie “flower power” and the

closely related anti-Vietnam war movement were

socio-political revolutions. In Europe, 2019 marks

the 100th anniversary of the end of the “war to end all

wars” and the 75th anniversary of D-Day.

Counterpointing this societal turmoil, technology

gave us hope. Neil Armstrong and Buzz Aldrin walked

on the moon. Doug Engelbart and his team presented

the “Mother of All Demos” of NLS at the ’68 Fall Joint

Computer Conference. Ivan Sutherland’s pioneering

Sketchpad (that demo’d interactive graphics in

1963) and Engelbart’s NLS demo were two landmark

events that were early examples of interactive

computing in an era of batch computation. Interactive

computing on time-sharing systems, combined with

microminiaturization, would lead more than a decade

Andries (Andy) van Dam is the Thomas

J. Watson, Jr., University Professor of

Technology and Education and Professor

of Computer Science at Brown Univer-

sity, where he has been on the faculty

since 1965. He was the co-founder of the

CS department and its first chairman,

and has worked in interactive graphics

and hypermedia since the mid-60s.

later to the birth of the personal computer. It caused a

revolution in the dominant model of computing that was

centered on large mainframes and minicomputers used

for science and engineering, finance and commerce.

Interactive computing based on computer graphics and

its use in hypermedia systems characterizes most of my

research career.

In 2019, it is difficult to remember the impact that

interactionbased information structuring and sharing

had on society; it certainly shaped my research career.

In this presentation, I will reflect on the development

of five decades of hypermedia systems and will demo

three systems that have been highlights of my journey in

hyperland. First, I’ll show our FRESS hypertext system (still

running 50-year old assembly code!), with the database of

poetry used by a class of English students in 1976 in what

is arguably the first online scholarly community. Next, I

will demo our TAG (Touch Art Gallery) used by the Nobel

Foundation a few years ago for a traveling exhibition on

Alfred Nobel and all the Nobel Laureates.

Finally, I’ll interweave the hypertext-centric parts of my

talk with some source material stored in an unbounded 2D

workspace, using our current hypermedia system Dash,

which is still under development and in an early but already

useful state. These systems will be presented in the

context of the research trends that led, ultimately, to the

interconnected society in which we live. All of us working

on our first hypertext systems in the ’60s understood

the potential of this technology. What I did not predict

is that 50 years later the revolution in human-centered

computing would remain far too unfinished in terms of its

positive societal impact. Indeed, that impact and utility

are increasingly in jeopardy from a variety of forces, both

economic and political. I will close with some thoughts

on both deliberately designed and unanticipated societal

issues of social media that I feel we technologists must

urgently help address.

31KEYNOTE SPEAKER

Manfred WeberKeynote SpeakerHis main political focus is on bringing Europe back to the

people and on uniting them behind concrete common

ideas for the future of our continent, such as the fight on

climate change, a European master plan against cancer

and more fairness in a digitalized economy. In his keynote

speech he stressed the need for further democratization

of the European Union. Only if the people feel involved, we

will be able to jointly take up the big challenges of our time

and to defend our freedom, our unity and our “European

way of life” instead of creating new divisions. 30 years

ago, the fall of the Berlin Wall and the Iron Curtain brought

freedom and prosperity to the people of Europe. If we

want to preserve these huge achievements, we must also

break down the walls in other areas or prevent new walls

from being built.

Manfred Weber is the Chairman of

the European People‘s Party (EPP)

Group, the largest political group

in the European Parliament, since

2014. He has played a key role in

making the EPP Group the most

united political force in plenary.

In 2019, Manfred Weber was

Lead Candidate of the European

People‘s Party for the Election of the

European Parliament.

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.

33LOCATIVE HYPERFICTION

The Dean of Liminal StudiesA Locative Hyperfiction

The Academy. A manifestation of the ideal University, existing in trans-dimensional liminal space, and simultaneously connecting all campuses in all times. But in some places, the threads wear thin. How committed are we to scholarship, to study, to our fraternity – and what walls are we unwittingly building? The Dean of Liminal Studies is coming to inspect our campus and see how we measure up. But no-one knows what the Dean really wants…

The Dean of Liminal Studies was

written as part of the 48-hour

hypertext challenge for ACM

Hypertext 2019 held at Hof

University, but was inspired by

the idea of writing a story that

might be read in any campus of

any University in the world. That

made us think about the ideals

and values that unite academia,

and the real-world pressures

that challenge those values. We

wondered what a place would

be like that embodied those

ideals, and how we might be

judged by someone from that

place. Our titular Dean.

34 48 HOUR HYPERTEXT

48 Hour Hypertext#48hHypertext

A challenge was issued to members of the hypertext

research community to create a complete hypertext

fiction in no more than 48 hours of work. Writers were

asked to submit the work as well as short reflections

on issues of craft and technique they encountered in

the course of the project. We expect the results of the

challenge will present an opportunity for an engaging

panel that could influence hypertext writing, pedagogy

and technology.

35EXHIBITION

What does it mean to reunify

different areas of scholarship

surrounding hypertext and

social media? The response this

exhibition offers is: Reunification

would include, not only papers

by researchers, but also creative

output by artists who use various

hypertextual strategies and

participatory involvement for

producing highly experimental

narratives. Included in this

exhibition, therefore, are eight

leading artists from Europe,

North America, and Australia who

explore 3D animation, mobile

technology, hypertext platforms

like Storyspace and Twine, and

web languages for the purpose

of storytelling. Coordinating

with the conference theme, the

exhibition shows how hypertext

and social media can be used for

human creative expression and

so extends our understanding of

these technologies.

36 CONFERENCE SITE

Conference SiteThe conference will be held on the campus of Hof University, in the rooms of the iisys building (Institute of Information Systems).

Bus lines 6 and 7 serve the campus, where

the university marks the start/end. The

bus stop “Hochschule” is served every 15

minutes, distributed equally on lines 6 and 7

(every 30 minutes each).

There are some apps and websites available

to help finding your way:

#1 Official apps and website provided by the

state of Bavaria: Bavaria’s travel planner.

#2 A local research Project, called MobiDig,

investigates possibilities to improve various

aspects of mobility. They provide smartphone

apps especially for the region of Hof. The

apps do support German only, though they

are easy to use.
