Semantic Web journal Special Issue on
	"Visual Exploration and Analysis of Linked Data"



Linked Data continues on its exponential growth path, to include
manually curated datasets for specific tasks and domains and
heterogeneous data generated in the online and physical worlds, as the
modern, technology-rich and dependent user carries out ordinary
activities in today's increasingly inter-connected, knowledge-driven
world. Analysis and effective use of Linked Data however still lags far
behind its generation rate. The content of this vast, rich knowledge
resource therefore remains to a large extent untapped. Challenges faced
in browsing, analysing, consuming and reusing Linked Data exist, within
the Semantic Web community, the wider research community, industry and
the lay public.
Within the research community the potential of Linked Data and the
acknowledged challenges in its use are reflected in conference
sub-themes, workshops and challenges. This is in addition to industry
and research council-funded projects addressing varying aspects
concerning the use of Linked (Open) Data. In industry, these and related
challenges are increasingly being tackled under the umbrella of Big Data
and Big Data Analytics. For the ordinary end user, Linked Data may be
seen either as a portal to effective, timely, context-based knowledge
use, or a technological barrier to effective use of the touted knowledge
In all three cases, the need to provide usable means for harnessing the
knowledge content of Linked Data is a given. This special issue aims to
address this topic in what is an important, albeit still a nascent area
of research – visualisation of Linked Data. Visualisation provides an
intuitive, yet powerful means to analyse complex data and situations,
taking advantage of human perceptual abilities to, e.g., detect patterns
within data or quickly identify outliers. Appropriately designed
visualisation is able to support effective, exploratory knowledge
discovery, trigger new insight, and therefore enable its users to obtain
both an overview of the data and recognise and delve into detail in
regions of interest. Visualisation therefore supports more effective
analysis, and increased confidence in drawing conclusions about the
underlying data and in decision-making.

While visualisation in this field very often is geared toward
applications and reuse of Linked Data, as research progresses, new
algorithms and custom approaches to visualisation are being developed
specifically for Linked Data. This is very often under the umbrella of
the Semantic Web, but increasingly also falls within the Information
Visualisation and Visual Analytics communities. We invite submissions
that demonstrate novel and adapted techniques, and innovative approaches
to visual presentation, exploration and analysis of Linked Data,
targeted at Semantic Web experts, (data) domain experts and/or the lay user.

We solicit submissions that:
    1. describe novel tools designed to handle the challenges specific to visual exploration and analysis of Linked Data.
    2. demonstrate the use of visualisation and visual analytics to:
        * derive insight and extract knowledge from Linked Data,
        * support the generation and curation of new Linked Datasets, or extend selected topics within the current Linked Data Cloud.
    3.  illustrate the use of Linked Data to support or drive visual analytics and visualisation-based decision-making.
    4. describe use cases in which visualisation of Linked Data is employed toward reaching a specified end goal, or is applied with respect to a specified user type, task(s) and/or domain.
    5. evaluate visual approaches for browsing, analysing and consuming Linked Data.

Ontologies, particularly, are a vital component in the generation and
use of Linked Data, allowing community-specific terms and colloquial use
of language to be encoded using commonly agreed, formal terms or
concepts, and providing a structured approach for capturing and encoding
data with its context of use. Ontologies therefore allow more seamless
linking of the independently generated datasets that form the Linked
Data cloud. Effectiveness and correctness in the use of ontologies here
impacts the use of related data subsets within the Linked Data cloud. We
also invite submissions that illustrate how visualisation may be
employed to augment the use of ontologies in the generation and
consumption of Linked Data, and for linking data with related content
but incompatible structure or representation.


Submissions may fall within, but are not limited to, the following topics and areas:

1. Visualising, communicating and reusing the content of Linked Data, resolving where necessary, uncertainty, validity and dynamicity, via approaches including:
    * Visual analytics, considering both smaller sub-sets and domains within the Linked Data Cloud and scaling up to tasks requiring the traversal of multiple sub-sets, with inherent increase in data amount and complexity.
    * Collective intelligence
    * Search & discovery
    * Knowledge and content management
    * Ontology visualisation, analysis and usage
    * Social media data & networking

2. Application domains, using both open and restricted access linked data
    * Business, marketing & logistics
    * the Media
    * Government, public bodies & services, e.g., education, health, social welfare & housing
    * Scientific Disciplines that make use of Linked Data and principle and techniques for analysing Linked Data, such as Bioinformatics
    * Travel, Culture, Entertainment & Events
    * Geo-location

3. Evaluation & user studies
    * of visualisation-based approaches for browsing and analysing Linked Data
    * Visualisation as a means to improve usability of Linked Data
    * Usability studies & comparative analysis of existing visualisation approaches and tools
    * Benchmarks & metrics to support the evaluation of visualisation approaches and tools

4. Inter-disciplinary approaches to the application of Linked Data, such as Social and Web science studies.

5. Case studies examining application within research, in industry and for the lay user.
