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

2-4 September 2015 Cyprus
http://ht.acm.org/ht2015/

--- 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 personalization, 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

--- Track DIGITAL CONNECTIVITY —

In modern Web environments hypermedia content is increasingly generated, processed, filtered, adjusted, and personalized. Online social networks further generalize 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 organizations 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
* Personalization 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 scrutablility of adaptive hypermedia
* User modeling for adaptive hypermedia

— Track DATA CONNECTIVITY —

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 recognized 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

-- Track DIGITAL HUMANITIES —

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.
