Special Session description:
The evolution of technologies now effectively supports the creation and existence of the Web of Data. However, the production and mass consumption of data have been a matter of debate over methodologies that should be employed in the technological and business domain. Data over the Web can be seen under three major perspectives. One that deals with their "openness", one that addresses their interconnection and one that discusses new ways of managing their performance.
This special session aims to stimulate a multi-origin discussion about data production and deployment within the Web corpus. It is focused on new models, languages and applications that exploit the Web of data in order to act as a global repository of interlinked resources.
We seek original articles balanced between theoretical and practical approaches in research aspects and/or applications that utilize either Open, Linked and Big Data. We further encourage the submission of contributions that discuss and address exploitation issues of data in different disciplines. Submitted papers may deal with methods, models, case studies, practical experiences and technologies, but also with work in progress solutions. The thematic categories are divided in three parts:

1. Open Data
Definition@wikipedia: "Open data is the idea that certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control. The goals of the open data movement are similar to those of other "Open" movements such as open source, open content, and open access".

Topics of interest cover the following areas (but are not limited to):
- Business models, marketplaces and crowdsourcing platforms for Open Data
- Policies, strategies for the development of data ecosystems
- Country/nationwide challenges and opportunities
- Privacy and provenance issues
- Reliability and trustworthiness of Open Data
- Case studies for domain/sector-specific open data strategies (smart cities, environmental and geospatial research, social media)
- Methodologies for open data production, cleansing and utilization
- Heterogeneity, quality assurance, vocabulary repair and maintenance
- Benchmarks and metrics in Open Data usage
- Open Data usability, user interaction and case studies with lessons learned


2. Linked Data
From the moment they were officially introduced in 2008, Linked Open Data (LOD) and their applications are flourishing. The Open Data movement, along with the maturity of Web 3.0 technologies has led various Organizations to publish their data, making them accessible worldwide. One of the fundamental issues that follows the initial success of these LOD initiatives is a way to standardize the effort according to effective functional and technical specifications.

Topics of interest cover the following areas (but are not limited to):
- Methodologies for Linked Data production and deployment
- Assessing trustworthiness in Linked Data
- Linked Data publication and visualization
- AI technologies for Linked Data
- Engineering Linked Data stems
- Searching and ranking methodologies and algorithms
- Linked Data real world applications and uses (e-Government, health, energy, finance)
- Rule interchange formats
- Reasoning
- Query languages
- Data cleansing techniques
- Social media interactivity
- Adaptive Linked Data systems
- Services development and orchestration
- Provenance and right management
- Dataset description, discovery and consolidation
- Architectural paradigms
- Mobile Linked Data
- Business models

3. Big Data
In this thematic category we aim to investigate how the well-defined concepts of data utilization can be applied in order to develop new techniques and methods for the sustainable and socially balanced exploitation of huge data pools.

Topics of interest cover the following areas (but are not limited to):
- Scalable, distributed and parallel algorithms for solving Big Data
- Harvesting Linked Data from large heterogeneous sources
- Connecting massive unstructured data with well-defined linked formats
- Semantic models and environments to support Big Data
- Data management for mobile and pervasive computing
- Data Management in large social graphs
- Crowdsourcing as a solution to Big Data handling
- Big Data analytics in government and society (public sector, social security, etc.)
- Visualization and presentation of Big Data
- Security, privacy issues derived from Big Data handling
- Complex applications in:
- Science, scientific data mining
- Large scale recommendation systems (e.g. medicine, biology, finance, business, etc.)
- Communications and social media applications
- Real-life problems (urban, transportation, weather, energy consumption, etc.)
