Visualization and Interaction for Ontologies and Linked Data (VOILA) 2018 Call for Papers

Visualization and Interaction for Ontologies and Linked Data (VOILA)
4th International Workshop co-located with ISWC 2018, October 8, 2018, Monterey, CA, USA

http://voila2018.visualdataweb.org/

Motivation and Objectives

A picture is worth a thousand words, we often say, yet many areas are in demand of sophisticated visualization techniques, and the Semantic Web is not an exception. The size and complexity of ontologies and Linked Data in the Semantic Web constantly grows and the diverse backgrounds of the users and application areas multiply at the same time. Providing users with visual representations and intuitive interaction techniques can significantly aid the exploration and understanding of the domains and knowledge represented by ontologies and Linked Data.

Ontology visualization is not a new topic and a number of approaches have become available in recent years, with some being already well-established, particularly in the field of ontology modeling. In other areas of ontology engineering, such as ontology alignment and debugging, although several tools have been developed, few provide a graphical user interface, not to mention navigational aids or comprehensive visualization and interaction techniques.

In the presence of a huge network of interconnected resources, one of the challenges faced by the Linked Data community is the visualization of multidimensional datasets to provide for efficient overview, exploration and querying tasks, to mention just a few. With the focus shifting from a Web of Documents to a Web of Data, changes in the interaction paradigms are in demand as well. Novel approaches also need to take into consideration the technological challenges and opportunities given by new interaction contexts, ranging from mobile, touch, and gesture interaction to visualizations on large displays, and encompassing highly responsive web applications.

There is no one-size-fits-all solution but different use cases demand different visualization and interaction techniques. Ultimately, providing better user interfaces, visual representations and interaction techniques will foster user engagement and likely lead to higher quality results in different applications employing ontologies and proliferate the consumption of Linked Data.

Special Theme & Topics of Interest

This year, we plan to have a dedicated look on empirical evidence on the benefits and limitations of visualizations and interactions in the context of the Semantic Web. We are particularly interested in success and failure stories, in learning which visualization and interaction approaches work and which do not – to which extent and in which contexts. We would like to hear about novel research findings and insights, backed with empirical data from user studies and use cases. Submissions addressing this special theme could include one or more of the following:

  • success stories
  • failure stories
  • empirical studies

We also welcome other research contributions providing empirical evidence that advances the field.

Apart from that – and as in the last years -, we are looking for submissions addressing one or more of the following topics, subjects, and contexts (or related ones):

Topics:

  • visualizations
  • user interfaces
  • visual analytics
  • requirements analysis
  • case studies
  • user evaluations
  • cognitive aspects

Subjects:

  • ontologies
  • linked data
  • ontology engineering (development, collaboration, ontology design patterns,
  • alignment, debugging, evolution, provenance, etc.)

Contexts:

  • classical interaction contexts (desktop, keyboard, mouse, etc.)
  • novel interaction contexts (mobile, touch, gesture, etc.)
  • special settings (large, high-resolution, and multiple displays, etc.)
  • specific user groups and needs (people with disabilities, domain experts, etc.)

Submission Guidelines

Paper submission and reviewing for this workshop will be electronic via EasyChair. The papers should be written in English, following the Springer LNCS format, and be submitted in either PDF or in HTML on or before June 1, 2018. Abstracts are due on on or before May 25, 2018.

VISSOFT 2018 Call for Papers

The sixth IEEE Working Conference on Software Visualization (VISSOFT 2018) builds upon the success of the previous four editions of VISSOFT, which in turn followed after six editions of the IEEE International Workshop on Visualizing Software for Understanding and Analysis (VISSOFT) and five editions of the ACM Symposium on Software Visualization (SOFTVIS). In 2018, VISSOFT will again be co-located with ICSME in Madrid, Spain.

http://vissoft18.etsii.urjc.es/

Call for Papers

Software visualization is a broad research area whose general goal is to enhance and promote the theory, realization, and evaluation of approaches to visually encode and analyze software systems, including software development practices, evolution, structure, and software runtime behavior. Software visualization is inherently interdisciplinary, drawing on theories and techniques from information visualization and computer graphics and applying these in the software engineering domain.

The VISSOFT conference is principally a venue for publishing and discussing research related to software visualization. VISSOFT brings together a community of researchers from software engineering, information visualization, computer graphics, and human-computer interaction to discuss theoretical foundations, algorithms, techniques, tools, and applications related to software visualization.

This year’s VISSOFT, co-held with ICSME, encourages a variety of submissions that address outstanding challenges in software systems using visualization. This includes technical papers, empirical studies, applications, case studies, and papers that present novel ideas and tools.

Topics of interest include:

  • Innovative visualization and visual analytics techniques for analysis of software engineering data. This includes source code, dependencies, repositories, developer social networks like StackOverflow and GitHub, mobile app reviews, documentation, runtime logs, and DevOps data.
  • Visualization to support software development activities, including design, requirements engineering, program comprehension, software testing, and debugging.
  • Interaction techniques and algorithms for software visualization.
  • Visualization-based techniques in software engineering education.
  • Integration of software visualization tools with development environments.
  • Empirical evaluation of software visualizations.
  • Industrial experience with using software visualization.
  • Applications of new technologies to enhance software visualization, including virtual reality, augmented reality, gamification, and machine learning.

We solicit papers that present original, unpublished research results. Papers will be rigorously reviewed by an international program committee. In addition to technical papers, VISSOFT features a New Ideas or Emerging Results (NIER) track and a Tools track. All accepted submissions will appear in the conference proceedings and the IEEE Digital Library.

Submission Types

Technical papers

A technical paper contribution must describe an in-depth and mature research result relevant to software visualization. The content of a technical paper can be at a maximum 10 pages long (including all figures, tables, and appendices). However, the 10 page limit does not include the bibliography, which is not limited in length.

The submission of a video (up to 5 minutes in length) to accompany the paper is highly encouraged to show interaction possibilities. Authors who wish to submit a video can submit the video together with their paper if the size of the video is smaller than 50 MB, otherwise a URL to the video should be provided.

Authors will be given the opportunity to provide a response to reviewer requests for clarifications before a final decision is made.

After the notification, authors can also submit an artifact (tool, data, model, etc.). The following section provides more info about it.

Important Dates:

Abstract Submission date: May 1, 2018
Paper Submission date: May 8, 2018
Author Response Period: June 1 – June 5, 2018
Notification: June 15, 2018
Submission link: https://easychair.org/conferences/?conf=vissoft2018

Artifacts:

Traditionally, technical research papers are published without including any artifacts (such as tools, data, models, videos, etc.), even though the artifacts may serve as crucial and detailed evidence for the quality of the results that the associated paper offers. Following the effort initiated at ESEC/FSE’11, authors of accepted technical papers at VISSOFT 2018 can have their artifacts evaluated by the program committee. Positively evaluated artifacts will be reflected in the paper publication, presentation, and be formally announced during the conference. A paper with an accepted artifact will have five extra minutes of presentation which can be used to present the artifact. The authors will also be invited to demo the artifact during the interactive informal demo session organized for the tool demo track.

Given the short time between the acceptance notification and the deadline to submit the artifact, we suggest the authors to start preparing it beforehand.

Finally, for more information about the artifact evaluation process visit http://www.artifact-eval.org.

Important Dates:

Artifact Submission: June 22, 2018
Artifact Notification: July 11, 2018
Submission link: https://easychair.org/conferences/?conf=vissoft2018

NIER and Tool papers

We accept two types of paper submissions: NIER contributions (New Ideas and Emerging Results) and Tool contributions.

The NIER contributions describe work-in-progress and preliminary exciting results. Authors should include open questions and even provocative hypotheses to get early feedback on their research ideas or even support through new research collaborations. NIER papers have to be maximum 5 pages long (including bibliography).

Tool contributions describe the design or actual utilization of software visualization tools, with a focus on relevant tool construction aspects or the use of the tool for gaining new insights. Authors should be prepared to demonstrate their tool at the conference. The submission may also contain a link to a screencast (e.g., YouTube or Vimeo video). Tools papers have to be maximum 5 pages long (including bibliography).

Important Dates:

Paper submission date: June 11, 2018
Notification: July 2, 2018
Submission link: https://easychair.org/conferences/?conf=vissoft2018

VL/HCC 2018 Call for Papers

IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC 2018)

1-4 October, 2018 – Lisbon, Portugal

http://vlhcc.org

IMPORTANT DATES
—————

– Abstract Submission: 6 April 2018
– Paper Submission: 13 April 2018
– Review Notifications: 15 June 2018
– Rebuttal Deadline: 22 June 2018
– Paper Notification: 6 July 2018
– Camera Ready copy: 27 July 2018
– Conference: 1–4 October 2018

SCOPE AND TOPICS
—————-

We solicit original, unpublished research papers on computing technologies and visual languages for modelling, programming, communicating, and reasoning, which are easier to learn, use or understand by humans than the current state-of-the-art. Papers should focus on efforts to design, formalize, implement, or evaluate those technologies and languages. This includes tools and visual languages intended for general audiences (e.g. professional or novice programmers, or the public) or domain-specific audiences (e.g. people working in business administration, production environments, healthcare, urban design or scientific domains).

This year’s special topic is “Building Human-Adaptive Socio-Technical Systems”. Systems in which humans are both developers of and intrinsic parts of the system are becoming more common. These Human-Adaptive Socio-Technical Systems adapt to changes in context and the behavior of human users. Example systems include situation-aware human-assistance systems and learning-based cooperative control systems in a variety of application areas including Internet-of-Things applications and Cyber-physical social systems. These kinds of systems require human-centered concepts, languages and methods in two separate contexts: to specify system behavior and to assist in modeling human behavior.

Areas of interest include, but are not limited to:

– Novel visual languages
– Design, evaluation, and theory of visual languages
– End-user development, adaptation, and programming
– Domain-specific languages
– Visual modeling of socio-technical systems
– Visual modeling of human behavior
– Visual modeling of digital twins of humans
– Interdisciplinary approaches (e.g. psychology, sociology) to human aspects
– Human aspects and psychology of software development and language design
– New representations and user interfaces for explaining system’s behavior
– Computational thinking and computer science education
– Problem solving through programming and play
– Debugging and program understanding
– Crowd Sourcing design and development work
– Software visualization
– Technologies and infrastructures for end user development
– Technology acceptance and adoption studies
– Evaluation of end user development technologies

PAPER SUBMISSIONS
—————–

We invite two kinds of papers:

– full-length research papers, up to 8 pages – plus unlimited additional pages containing only references

– short research papers, up to 4 pages – plus unlimited additional pages containing only references

Supplemental Materials: In addition to papers, authors may optionally submit supplemental materials that support their papers. Examples of supplemental materials include short digital videos, copies of study instruments, or experimental methodologies. Supplementary material should be briefly described in the paper body. However, since not everyone who reviews your paper may review submitted supplemental materials, your submission must stand on its own without the supplemental materials. The supplemental materials will be distributed at the conference and will appear in the IEEE Xplore Digital Library. Videos must be at most 3 minutes in length, at most 100 MB in size, and prepared as MP4 files using the H.264 codec. All supplemental materials must adhere to the IEEE preparation instructions: https://www.ieee.org/documents/MMdocumentation.pdf.

Papers and supplemental materials must be submitted using the EasyChair system:

https://easychair.org/conferences/?conf=vlhcc2018

* Please note that we will follow a double-blind reviewing mechanism for 2018. *

To facilitate assigning papers to reviewers, we require paper abstracts to be submitted via EasyChair at least one week before the paper submission deadline. The abstract must be no longer than 150 words and must be kept up-to-date such that it exactly matches the abstract in the submitted paper.

All accepted papers, whether full or short, should be complete, self-contained, archival contributions. Contributions from full papers are more extensive than those from short papers. Work-in-progress, which has not yet yielded a contribution, should be submitted to the Showpieces category. All submissions will be reviewed by members of the Program Committee. Submission and reviews for the technical program are managed with EasyChair. At least one author of each accepted paper is required to register for VL/HCC 2018 and present the paper at the conference. IEEE reserves the right to exclude a paper from distribution after the conference, including IEEEXplore® Digital Library, if the paper is not presented by the author at the conference.

Accepted papers will be distributed at the conference and will be included in the IEEE Xplore Digital Library (http://ieeexplore.ieee.org/). The proceedings are an official electronic publication of the IEEE in Computer Science, with an ISBN number. Be sure to use the current IEEE conference paper format: http://www.ieee.org/conferences_events/conferences/publishing/templates.html.

DOUBLE BLIND REVIEWING
———————-

We follow a light-weight double-blind reviewing process. Thus, submitted papers must not reveal the identities of authors. However, the author names will be known to the program committee in the rebuttal phase.

Both authors and reviewers are expected to make every effort to honor the double-blind reviewing process. In case of questions, please contact the Program Chairs.

Authors should ensure that the submission can be evaluated without it being obvious who wrote the paper. This means leaving author names off the paper and using terms like “previous research” rather than “our previous research” when describing background. However, do not hide previous work – papers must still reference all relevant research, including that by the current authors, so reviewers can evaluate novelty. It is important that authors specify all conflicts of interest with potential reviewers during the submission phase.

Reviewers should not undertake any investigation that might lead to the revealing of authors identity. If identities are inadvertently revealed, please contact the Program Chairs.

The Program Chairs will check all submissions for obvious signs of lack of anonymity and may ask authors to make changes and resubmit the paper within four days of the submission deadline.

EVALUATION AND JUSTIFICATION
—————————-

Papers are expected to support their claims with appropriate evidence. For example, a paper that claims to improve programmer productivity is expected to demonstrate improved productivity; a paper that claims to be easier to use should demonstrate increased ease of use. However, not all claims necessarily need to be supported with empirical evidence or studies with people. For example, a paper that claims to make something feasible that was clearly infeasible might substantiate its claim through the existence of a functioning prototype. Moreover, there are many alternatives to empirical evidence that may be appropriate for justifying claims, including analytical methods, formal arguments or case studies. Given this criterion,we encourage potential authors to think carefully about what claims their submission makes and what evidence would adequately support these claims. In addition, we expect short papers to have less comprehensive evaluation than long papers.

REVIEWING PROCESS
—————–

Papers will be reviewed as follows:

– Initial review period: at least three members of the Program Committee or external reviewers will review each paper. At the end of this period, these initial reviews will be released to the authors.

– Author response period: authors will have an opportunity to submit a response based on their initial reviews. Responses should focus on answering reviewers’ questions, addressing reviewers’ concerns, and clarifying any factual misunderstandings. At this point, the identity of authors will be revealed to the program committee.

– Final review period: taking the author response into account, the original reviewers will revise their reviews as they deem appropriate, and the Program Committee will reach a final decision to accept or reject the submitted work.

VL/HCC 2017 Summary

Guest post by Denae Ford, PhD student at NC State University.

This year’s IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC) was hosted in the beautiful City of Oaks—Raleigh, North Carolina. This was only my 2nd VL/HCC, but from what I could tell the atmosphere was still filled with familiar faces with innovative approaches and exciting results to share!

The conference was hosted in the Marbles Kids Museum which appropriately matched the Programming and Play special topic from the call for papers (CFP). This year’s conference was also co-located with 2nd Blocks and Beyond Workshop which brought many researchers interested in the K-12 learning gains from block-based interfaces. I really think this was a new twist from last year’s VL/HCC co-location with PPIG in Cambridge, UK.

I think the best representation of all the refreshing intersection was at the reception on Wednesday night at the Nature Research Center. The evening consisted of graduate consortium posters, showpieces, and demonstrations around the exhibits ocean excursions, microorganisms, and unraveled DNA. One very cool demo was by Alessio Malizia where he demoed a tool named TAPASPlay which used shapes as input and output of an algorithm to teach computational thinking.

During the days, there were many amazing talks were given, but I’ll just highlight a few here:

Mary Beth Kery, a doctoral candidate at Carnegie Mellon University, presented the high value of exploratory programming from prior literature but also what it could mean for data scientist and other types of programmers learning through play(trial and error).


Titus Barik
, researcher at Microsoft Research, presented nostalgic concepts of play that got many of us into programming and reflected on how those concepts are reflected in how we program today.

I, Denae Ford, also presented our work on peer parity and presented how we can use identity to help programmers re-engage in online Q&A communities. I’ve shared my slides, paper, and blog online!

Chris Crawford, an assistant professor at the University of Alabama, presented the very meta experience of programming using alpha and beta waves of EEG into block programming environments.

Betsy DiSalvo, was or final keynote of the day and discussed how we use metaphors to understand concepts in CS, see Value-driven Learning: Decoding and Building upon Playful Computing Education. However, she shined light on the fact that those concepts are only specific to culture are difficult to expand beyond the context of a single lens of white men. This becomes an issue when programmers from different cultures try to enter the field. She challenged us to examine our language, what we consider playful, what our audience values, and to self-reflect on our expert blind spots.

I also attended the graduate consortium, chaired by Eric Walkingshaw where it was a very welcoming atmosphere for feedback. Faculty panelists also include Marian Petre, Katie Stolee, and Scott Fleming.

I must say it was one of the most constructive doctoral consortiums I have ever attended. The feedback was practical, healthy difference in approaches, large projects were scoped, and the students were very engaged.
