Ambiguity creates uncertainty in practically every facet of the web.
Machine learning, recommender systems, web search, as well as news and
systems that support human discourse, experience aspects of ambiguity and
subjectivity that leads to inaccuracies, poor and undesirable performance.
In crowdsourcing, human computation, and human-in-the-loop systems, topics
central to TheWebConf, recent research has attempted to delve deeper into
subjectivity and ambiguity, finding it to manifest in human-collected data
primarily as disagreement [Cheatham and Hitzler, 2014; Plank, Hovy and
Sogaard, 2014; Bayerl and Paul, 2011; Aroyo and Welty, 2015; Schaekermann,
Law, Williams and Callaghan, 2016; Chang, Amershi and Kamar, 2017; Lin and
Weld, 2014; etc.]. This includes the information presented to workers as
part of a crowdsourcing task, the instructions for what to do with it, and
the information they are asked to provide. These ambiguities become deeply
tied into our machine learning models and metrics, as they are in the gold
data. Similar ambiguity is found in interpreting and deriving utility from
user generated data from large scale systems such as social media and
search engines. Another aspect of disagreement surfaces in collaborative
projects such as Wikipedia, online forums, and semantic markups. In
language, ambiguity can result from missing details, contradictions and
subjectivity. Subjectivity may stem from differences in cultural context,
life experiences, or individual perception of hard-to-quantify properties.
All of these can leave people with conflicting interpretations, leading to
results that system builders would regard as "wrong". These issues share
common ground with many areas of interest to TheWebConf.

SAD2019 (Subjectivity, Ambiguity and Disagreement in Crowdsourcing)
Workshop aims to bring together a latent community of researchers who treat
disagreement (and subjectivity and ambiguity) as signal, rather than noise.
Such researchers use theoretical and empirical methodology to characterize,
utilize, mitigate and derive value from subjectivity, ambiguity and
disagreement.  The workshop will include invited talks, short technical
talks and a discussion of medium- and long-term challenges to fuel future
work.

We encourage interdisciplinary submissions from the broad spectrum of
crowdsourcing
and human computation research in fields and application areas, such as
computer science, information sciences, law, medical data analysis,
communication science and political science, as well as those primarily
working on human computation and crowdsourcing.  Solutions to these
challenging problems will benefit from a diverse set of perspectives.
Topics of interest (but not limited to) are:


   -

   Interaction/relation between disagreement, ambiguity and subjectivity
   -

   Costs and challenges introduced by ambiguity
   -

   Designing tasks with high subjectivity and low inter-rater reliability
   (e.g., semantic, linguistic, common sense, moral judgements.)
   -

   Better metrics for characterizing disagreement (over traditional
   inter-rater reliability)
   -

   Ambiguity in human computation task design, how to identify it and what
   to do about it
   -

   Theoretical ambiguity-aware frameworks for collecting data
   -

   Teasing apart different sources of ambiguity
   -

   Best practices for collecting subjective data
   -

   Benchmarks and datasets for studying ambiguity
   -

   Grand challenges that will further our understanding of subjectivity,
   ambiguity and disagreement
   -

   Disagreement, ambiguity, subjectivity and their representation and
   interaction in different content modalities, e.g. text, images, videos,
   audio
   -

   Interdisciplinary perspectives on disagreement, ambiguity and
   subjectivity, e.g., law, political science, humanities


>>>>>> SUBMISSION >>>>>>

Authors can submit four types of papers:

   -

   short papers (up to 6 pages in length), plus unlimited pages for
   references
   -

   full papers (up to 10 pages in length), plus unlimited pages for
   references
   -

   position papers (up to 4 pages in length), plus unlimited pages for
   references
   -

   demo papers (up to 4 pages in length), plus unlimited pages for
   references


Submissions may present ideas, results from experimental studies,
methodologies, work-in-progress and/or applications of systems that explore
the topics of subjectivity, ambiguity and disagreement  in crowdsourcing
and human computation in relation to computational systems, applications,
or services. Page limits include diagrams and appendices. Submissions
should be formatted according to the formatting instructions in the General
Guidelines
<https://www2019.thewebconf.org/call-for-papers#general-guidelines>.The
proceedings of the workshop will be published jointly with the conference
proceedings of TheWebConf 2019.



Submit papers through https://easychair.org/conferences/?conf=sad2019

All submissions must be written in English.
