Preface
A picture is worth a thousand words, we often say, yet many areas are in demand of so-
phisticated 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 signif-
icantly 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 avail-
able 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 recently been developed, few provide a graph-
ical 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 pro-
vide 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, rang-
ing 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 represen-
tations and interaction techniques will foster user engagement and likely lead to higher
quality results in different applications employing ontologies and proliferate the consump-
tion of Linked Data.

These and related issues are addressed by the VOILA! workshop series concerned with
Visualization and Interaction for Ontologies and Linked Data. The second edition of
VOILA! is co-located with the 15th International Semantic Web Conference (ISWC 2016)
and will take place as a full day event on October 17, 2016 in Kobe, Japan. It will be orga-
nized around scientific paper presentations and discussions, and will be accompanied by
interactive software demonstrations, giving developers a chance to gather feedback from
the community.

The call for papers for VOILA! 2016 attracted 22 submission in different paper categories.
Three reviewers were assigned to each submission. Based on the reviews, we selected 15
contributions for presentation at the workshop in the following categories: full papers (7),
system papers (2), short papers (2), demo papers (4).
We thank all authors for their submissions and all members of the VOILA! program com-
mittee for their useful reviews and comments. We are also grateful to Chiara Ghidini and
Heiner Stuckenschmidt, the workshop chairs of ISWC 2016, for their continuous support
during the workshop organization.
