================CALL FOR TUTORIAL/WORKSHOP PROPOSALS==================
In conjunction with Hypertext 2015, the 26th ACM Conference on Hypertext and Social Media.
Middle East Technical University, Northern Cyprus Campus, Cyprus
September 1-4, 2015
March 13, 2015: Tutorial and workshops proposals due
The ACM Hypertext conference focuses on 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 26th ACM  Conference on Hypertext and Social Media conference is pleased to invite proposals for tutorials to be held with the conference.

The goal of tutorial is to present state-of-the-art theories, methodologies and  techniques from experts in the field. Topics of interest should be related to the main conference tracks, in relation on novel aspects to be examined in deep. Interdisciplinary tutorials are also encouraged. We expect proposals for half-day tutorials. 

The goals of the workshops are to provide a more informal setting for exchanging opinions, to share experiences, presenting ideas, foster research community and identify open problems and/or explore directions for future research. As such, they also offer a good opportunity for researchers to present their work and to obtain feedback from an interested community in an interactive atmosphere. Proposals are especially encouraged on emerging topics, somehow related to the main conference tracks (links and connection between people, open data and the semantic of things, user experience and adaptive linking), but are not limited to other (novel) topics which might be of interest for the hypertext community. Acceptance of workshop proposals will be based on the experience and  background of the organizers in the topic, and on the relevance of the subject matter with regard to the topics addressed in the main conference. We welcome proposals for different types of workshops, from working groups on a specific topic to more traditional conference-like workshops. However, we prefer interactive workshops that guarantee richer active interactions among participants and provide significant room for controversial and stimulating discussions.We preferentially would rather proposals for half-day workshops. The need for a full-day workshop should be motivated by some particular reason. Potential proposers are invited to discuss their ideas with the workshop chair before working out a detailed proposal.

====================== PROPOSAL FORMAT (TUTORIALS)=========================
The tutorial proposals - not longer than 3 pages - have to be sent by email to the workshop chairs, and must contain the following information:
- Title of the tutorial
- Tutorial presenters (affiliation, contact details, homepage, and prior
experiences with tutorial organization, if any).
- Keywords (describing the main themes of the tutorial) (from 3 to 5)
- Abstract (up to 70 words)
- Description of the tutorial (topics and goals of the tutorial)
(up to 500 words)
- Motivation  (why the topic is of interest for the conference audience)
- Tutorial format (lessons, exercises, etc)
- Intended audience and expected attendance (with historical data of past
versions of the tutorial, if available)
- Previous editions of the tutorial (if applicable) (URLs, conference it was
co-located with, number of participants , and any other relevant

The organizers of accepted tutorials are then expected to prepare a tutorial Web Site with the information about the tutorial. 

====================== PROPOSAL FORMAT (WORKSHOPS)=========================
The workshop proposals‚ not longer than 5 pages - have to be sent by email to the workshop chairs, and must contain the following information:

- Title of the workshop and acronym

HT2015, Call for Papers for Main Research Tracks
26th ACM Conference on Hypertext and Social Media

2-4 September 2015

— Conference Scope —

The ACM Conference on Hypertext and Social Media conference (HT) is a premium venue for high quality peer-reviewed research on theory, systems and applications for hypertext and social media. It is concerned with all aspects of modern hypertext research, including social media, adaptation and personalisation, user modeling, linked data and semantic web, dynamic and computed hypertext, and its application in digital humanities.

HT2015 will focus on the role of hypertext and hyperlink theory on the web and beyond, as a foundation for approaches and practices in the wider community. Therefore, HT2015 has the following tracks:

* Digital Connectivity
* Data Connectivity
* Digital Humanities


In modern Web environments hypermedia content is increasingly generated, processed, filtered, adjusted, and personalised. Online social networks further generalise the conventional notion of the hypermedia to imply connections between users via their content and media. Making sense of     these complex processes has attracted significant attention in various research disciplines.

The Digital Connectivity track targets developing deeper insights into the mechanisms of information generation and dissemination, characterization of evolutionary processes on online social networks, studies of models and systems that support these processes, and the broader implications of these for organisations and society. The track provides a forum for researchers and practitioners to exchange information regarding     advancements in the current state of art.

Addressing problems in the Digital Connectivity space necessitates expertise in several domains: Computer and Information Science, Social Sciences, Psychology, and Economics. Hence submissions of inter-disciplinary works are highly encouraged. We also welcome works that explore how Digital Connectivity can be applied in diverse domains, such as Education, Health, Journalism, Government, Environment, and Media.

Topics of interest of the track include (but are not limited to):
• Adaptive authoring and design of hypermedia
• Adaptive hypertext frameworks and toolkits
• Community and social circle evolution
• Crowdsourcing and social media
• Enhancing hyperspace with recommendations
• Expertise and trust in online social networks
• Hypermedia classification and metadata systems
• Information diffusion in social networks
• Information interfaces and navigation support
• Information visualization of social data
• Language analytics in social media
• Mobile hypermedia and social media
• Narrative generation and presentation
• Personalisation for hypermedia and social networks
• Social information seeking and retrieval
• Social network and social media analytics
• Spam and malicious activity discovery in social systems
• Spatio-temporal analysis of hypermedia and social networks
• Usability and scrutability of adaptive hypermedia
• User modelling for adaptive hypermedia

The need to make data available on the Web using formats and protocols that make them easier to consume by potential data reusers has been widely recognised and accepted by data owners.     This is especially the case with Open Government Data initiatives, although this need has also arisen and dealt with in areas such as Culture, Journalism, Science, etc.     Besides the obvious method of placing isolated datasets as files on Web servers, probably with some simple metadata associated to them, several other alternative methods have been proposed for making different types of data available on the Web: Linked Data, CSV on the Web, REST APIs, etc. Once these are available, they can be used inside data value chains to generate more added-value data, data-intensive applications, etc.

This track deals with the methods, techniques and technologies that can be used to make data available on the Web, with a special focus on how heterogeneous data sources can be connected to each other, hence breaking data silos on the Web.     We are not only focused on using Linked Data approaches, which sit naturally for this purpose, but also on any other alternative approaches that may allow for such data publishing, description and interlinking.     In fact, we welcome submissions that address any of the steps of the data-on-the-Web lifecycle, including the creation, interlinking, entity and relation extraction, semantic annotation, analysis and modeling, dynamics and evolution, and applications of connected data on the Web.

Topics of interest include, but are not limited to:
• Web and connected data publication, annotation and curation
• Web and connected data linking and integration
• Web and connected data wrangling
• Analysis, mining, modeling and management of Web and connected data, including Linked Data, knowledge graphs, Web tables, and social network data
• Web and connected data dynamics and evolution
• Web and connected data provenance, privacy, and trust
• Web and connected data in scholarly communication and publication
• Crowdsourcing for Web and connected data
• Applications using Web and connected data for the Web, mobile devices, and social media
• Scalability of data connectivity and linking algorithms and infrastructures
• User experience with Web and connected data

With its wide-spread adoption, the World Wide Web has become a highly detailed yet biased reflection of human social behavior. The web in general and social media in particular have become attractive textual and non-textual data sources that potentially capture aspects of how people think/feel/behave in social situations (social psychology), relate to each other (sociology), govern themselves (political science), handle wealth (socioeconomics), or create culture (anthropology). While these phenomena have received attention from different communities, understanding human social behavior via unobtrusive methods (i.e. methods where the researcher doesn’t intrude into the research context) remains a challenging endeavor and an open problem. Tackling these challenges requires the development of new methods, instruments and techniques as well as an interdisciplinary effort from researchers across disciplines.
In this track, we seek submissions contributing to studies of the web from an interdisciplinary perspective. In particular, we are seeking to attract work on the intersection between computer science on one hand, and the humanities and social sciences on the other.
Topics of interest of the track include (but are not limited to):
• Studies of human culture based on online social networks and encyclopedia, computational methods to assess human culture along different dimensions (such as language, food, music, literature etc)
• Using social media to study psychological phenomena, and corresponding methods to assess psychological phenomena via web-based investigations
• Biases in social media, such as population biases, channel bias, self-selection bias, etc and computational methods for assessment and correction
• The study of limitations of tools used in digital humanities, extension of traditional source criticism into the development of systematic “tool criticism”
• Social and individual inequalities on the web, e.g. gender or race disparities, computational methods and instruments to assess and track inequalities
• Studies of political processes and dynamics on the web, such as elections, political unrest, grassroots movements
• Predictions with social media, e.g. stock markets, spread of language, culture, memes or diseases.
• Longitudinal studies of social phenomena and social change on the web
• Computational methods to assess and improve social and/or individual well-being via the web
• Studies investigating the role and causal impact of algorithms in facilitating social interactions on the web
• Innovative instruments for distant reading and quantitative methods in humanities and social sciences
• (Semi-)automated instruments to annotate social media data with constructs relevant for social sciences / the humanities.
