Visualizing and Animating Large-scale Spatiotemporal Data with ELBAR Explorer

Visual exploration of data enables users and analysts observe interesting patterns that can trigger new research for further investigation. With the increasing availability of Linked Data, facilitating support for making sense of the data via visual exploration tools for hypothesis generation is critical. Time and space play important roles in this because of their ability to illustrate dynamicity, from a spatial context. Yet, Linked Data visualization approaches typically have not made efficient use of time and space together, apart from typical rather static multivisualization approaches and mashups. We developed ELBAR explorer that visualizes a vast amount of scientific observational data about the Brazilian Amazon Rainforest. The core contribution is a novel mechanism for animating between the different observed values, thus illustrating the observed changes themselves.

ELBAR-explorer will be demoed at ISWC2014 in October, 2014. The following paper will give more details:

Tutorial on Information Visualization for Innovating Research Methods at Spatial Cognition 2014

We will organize a Tutorial on Information Visualization for Innovating Research Methods at Spatial Cognition 2014 (SC2014)  conference in Bremen on September 15th, 2014. The teachers of the tutorial are Tomi Kauppinen (Cognitive Systems Group, University of Bremen) and Willem van Hage (SynerScope B.V.).

In the tutorial we will introduce visual approaches for investigating spatial data in the context of other dimensions (such as social or temporal). The goal is to show via examples how information visualization, exploration and interaction support innovating new research methods. The tutorial materials will be made available online at LinkedScience.org/tutorials.

The main tutorial exercises will be done within the morning of the tutorial day.  For the afternoon there is an optional session for studying how to apply visual analytics techniques to data brought by participants.

Thus while the focus of hands-on exercises of the morning session is in existing case examples the optional afternoon session is more about brainstorming and exchanging ideas about suitable methods for the data from the participants.

Register to SC2014 and tutorial today here.

Making Sense of Data is the theme of Linked Science 2014

We will organize the 4th Workshop on Linked Science 2014 (LISC2014) with the focus on theme Making Sense Out of Data. LISC2014 will collocate with ISWC2014 in Riva del Garda, Trentino, Italy on October 19 or 20, 2014.

We encourage submissions on both

  1. new results through making use of semantic reasoning or
  2. making innovative combination of existing technologies (such as visualization, data mining, machine learning, and natural language processing) with Semantic Web technologies to enable better understanding of data.

LISC2014 is organized by

- Jun Zhao, Lancaster University
- Marieke van Erp, VU University Amsterdam
- Carsten Keßler, Hunter College, City University of New York
- Tomi Kauppinen, University of Bremen
- Jacco van Ossenbruggen, CWI and
- Willem Robert van Hage, SynerScope B.V.

Please check the LISC2014 pages for more information and Call for Papers.

We arrange a tutorial on Visual Analytics with LOD and Social Media on May 26, 2014 in Greece

Our VisLOD tutorial is arranged on May 26, 2014 in Anissaras (Crete, Greece) at ESWC2014 conference. The idea is to bring together researchers and practitioners interested in visual and interactive techniques for exploring Linked Open Data and Social Media for e-Governance. Our hands-on tutorial will cover technical aspects from two perspectives:

  1. Social Media analysis and
  2. Visualisation of Social Media and Linked Data.

The teachers of the VisLOD tutorial are Dr. Vitaveska Lanfranchi and Mr. Suvodeep Mazumdar from the University of Sheffield (UK) and Dr. Tomi Kauppinen from the Aalto University (Finland).

Program of LISC2013 Sydney on October 21st, 2013 published

3rd International Workshop on Linked Science 2013—Supporting  Reproducibility, Scientific Investigations and Experiments (LISC2013)

When: October 21st, 2013
Where: Sydney Masonic Conference & Function Centre, Sydney, Australia
Collocated with the 12th International Semantic Web Conference (ISWC2013).

PROGRAM

9.00 – 10.00 Keynote by Carole Goble.

Results may vary: reproducibility, open science and all that jazz.

Abstract:
How could we evaluate research and researchers? Reproducibility underpins the scientific method: at least in principle if not practice. The willing exchange of results and the transparent conduct of research can only be expected up to a point in a competitive environment. Contributions to science are acknowledged, but not if the credit is for data curation or software. From a bioinformatics view point, how far could our results be reproducible before the pain is just too high? Is open science a dangerous, utopian vision or a legitimate, feasible expectation? How do we move bioinformatics from one where results are post-hoc “made reproducible”, to pre-hoc “born reproducible”? And why, in our computational information age, do we communicate results through fragmented, fixed documents rather than cohesive, versioned releases? In this talk, which I gave as a keynote at the 2013 joint conference Intelligent Systems in Molecular Biology / European Conference on Computational Biology, I will explore these questions drawing on 20 years of experience in both the development of technical infrastructure for Life Science and the social infrastructure in which Life Science operates.

TEACH Vocabulary Extended

We just published a new version of the TEACH vocabulary, which enables richer descriptions of courses as Linked Data. The vocabulary now supports quite a few new features, including classes and properties for defining assignments of courses. Here are some examples which illustrate the use of some of the new classes and predicates:

Moreover, now TEACH has quite a few classes as well: CourseAssignmentMaterialTeacherStudentGroupStudentModuleStudyProgram,
LectureBuilding and Room. Future work includes fine tuning of domain and range specifications. Moreover, classes and  properties will be better linked to other vocabularies.
