CFP: JWS special issue on Visualization and Interaction for Ontologies and Linked Data


The Journal of Web Semantics invites submissions for a special issue on Visualization and Interaction for Ontologies and Linked Data to be edited by Valentina Ivanova, Patrick Lambrix, Steffen Lohmann and Catia Pesquita. Submissions are due be 31 January 2017.

Visual representations take advantage of the humans' most powerful perceptual channel - the visual system - and play a crucial role in understanding complex data and acquiring insight. Interacting with visualizations is indispensable in order to facilitate understanding and to overcome limitations of the visual representations. Yet, surprisingly, the importance of visual user interfaces is often overlooked in the Semantic Web domain. The area needs sophisticated visualization and interaction techniques to help its users understand the knowledge represented by ontologies and Linked Data and to utilize it in a multitude of applications and domains. As any other knowledge-intensive area, the Semantic Web deals with inherently intricate content. This poses high demands on its users in their tasks, such as modeling, formalizing, editing, verifying, sensemaking, etc., and involves a variety of cognitive processes - perception, attention, working memory, reasoning, etc. These processes could be more efficiently supported if user interfaces encompassing well-designed visual representations and interaction techniques were available.

Ontologies and Linked Data are being used in more and more application areas and by users with increasingly diverse backgrounds, which presents additional requirements. While a number of user interfaces have become available in the past years, they are rarely based on analytical or empirical studies of users demands, task analysis or advances in cognitive sciences, which can prevent their potential in supporting the interaction between users and the Semantic Web to unfold. User evaluations of different types - observational studies, interviews, etc. - are needed to provide requirements and to analyze the benefits of the proposed solutions. Yet, such evaluations are rather uncommon in the Semantic Web community. Approaches do not only need to consider common interaction contexts but should also take advantage of the opportunities provided by new and emerging interaction contexts, ranging from mobile and touch interaction to visualizations on large and high-resolution displays, and encompassing highly responsive web applications.

Visualization and interaction can be essential to easily provide access to the increasing diversity of the knowledge modeled in ontologies. They are an integral part of ontology engineering to help bridge the gap between domain experts and ontology engineers. 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 recently been developed, few provide a graphical user interface, not to mention navigational aids or comprehensive visualization and interaction techniques.

Related to that, the capacity of the Linked Data initiative is underutilized, the main consumers are technology experienced users, one of the reasons being the lack of appropriate user interfaces and visualizations that support other user groups. Various visual and interaction approaches are needed to assist the variety of users who pursue diverse goals and pose individual requirements. In the presence of a huge network of interconnected resources, one of the challenges faced by the Linked Data community is, for instance, the visualization of the multidimensional datasets to provide for efficient overview, exploration and querying tasks.

The aim of this special issue is to present latest advances in the area and further attract attention to these issues from interested communities. Ultimately, providing better user interfaces, visual representations and sophisticated interaction techniques will foster wider adoption of Semantic Web technologies and likely lead to higher quality results in different applications employing ontologies and proliferate the consumption of Linked Data.

Topics of interest include (but are not limited to):

  • Visualizations and user interfaces for ontologies and Linked Data (overview, exploration, analysis, visual analytics, querying, etc.)
  • Visualizations and user interfaces for ontology engineering (ontology development, alignment, debugging, evolution, provenance, collaboration, etc.)
  • Case studies of applying visualizations in ontology engineering and Linked Data consumption
  • User evaluations of visual interfaces for Linked Data and ontologies
  • Analyses of different user types and needs
  • Cognitive aspects of interaction and visualization
  • Context-aware visualization and interaction techniques

CFP: JWS Special Issue on Industry and In-use Applications



As the Semantic Web and Linked Data have matured over the past decade, we have witnessed the growth and deployment of a variety of applications that exploit Semantic Web technologies and standards to solve customers’ problems in novel ways:  from semantic search on the Web and question answering systems leveraging large knowledge graphs to information integration and predictive analytics in domains as diverse as healthcare & life sciences and smart cities.  These applications have tested, stressed, and imposed real-world constraints on semantic technologies. First, they have imposed significant scalability requirements on Semantic Web systems such as knowledge graph stores, reasoners, etc.  Second, given the sheer size and decentralized nature of the Semantic Web and Linked Data, they have magnified data integration challenges, which were traditionally limited to integration across a few sources, to practical data integration at Web scale.

The goal of this special issue is to provide a venue for researchers and practitioners to share their experience in designing, developing, deploying and evaluating applications and solutions that leverage semantic technologies and standards to achieve practical benefit.  In addition to submissions addressing traditional challenges of scalability and data integration, we also encourage submissions focused on tooling supporting Semantic Web application development and deployment, concrete use cases and case studies. Specifically, we expect submissions on, but not restricted to, the following topics with an emphasis on how semantic technologies were uniquely able to tackle application requirements and users’ needs:
  • Case studies and use cases for solutions and applications exploiting semantic technologies 
  • Foundations, methods, tools and technologies for facilitating Semantic Web application development and deployment
  • Exploitation of large scale knowledge graphs
  • Applications and solutions using data mining and machine learning on Linked Data.
  • In-use Ontology and domain modeling
In particular, applications not specifically concerned with the (semantic) web are also relevant as long as they exploit semantic technologies.

JWS special issue on stream processing



The Journal of Web Semantics invites submissions to a special issue on Stream Processing to be edited by Monika Solanki and Jean-Paul Calbimonte. Submissions are due by 1 July 2015.
Processing data streams is one of the main challenges facing today’s decentralised and distributed systems, given the high dynamicity, heterogeneity and volume of real-time data generated by contemporary IT infrastructures. The application domains where streams play a central role include social networks, smart cities, mobile wearable sensors, internet of things, environmental monitoring and stock market analysis, to name just a few. All these streams of data, or infinite flows of information, already exist and are available in pervasive and ubiquitous data-rich environments. However it remains difficult and challenging to effectively process, query and derive results from them. In the area of databases, these research challenges led to the emergence of data stream and complex event processing systems, including data models, query languages, algebra and operational semantics for them. Nevertheless, research opportunities in this area are far from being exhausted. The imminent realization of the Internet of Things and the abundance of new sources of streaming data raise a set of new challenges, especially dealing with the variety and heterogeneity of the data. Clear foundations are required to solve problems such as data integration and real-time analytics, added to the need for better understanding the meaning and the value of streaming data on the web. Several attempts have been made to approach some of these challenges using the theoretical foundations and the tools of Semantic Web research. These works have resulted in systems that tackle different issues, including continuous query processing, stream reasoning, event detection, ontology maintenance or ontology-based data access.
The goal of this special issue is to provide a grounding for research on recent advances in stream processing and their underlying semantic technologies. Traditional challenges of scalability, information quality, and data integration are of interest, but also are specific projects that publish, study, or use data streams in innovative ways. More specifically, we expect submissions on (but not restricted to) the following topics.
  • Processing RDF Data Streams
    • Producing and consuming streams of RDF graphs
    • Modelling streams of structured data
    • Theoretical modelling of RDF streams
    • Automatic annotation of raw data streams
    • Processing noisy data, uncertainty, incomplete information
    • Semantic mining of RDF data streams
    • Mechanisms for integrating historical data with streaming data
    • Publishing Linked Stream Data
  • Querying semantic streams of data
    • Extensions to SPARQL for data streams
    • Complex event processing on semantic data
    • Ontology-based data access to data streams
    • Data dynamics, update, and synchronization
    • Optimisation of stream query processing
    • Correctness of stream query processing
    • Synthetic RDF streams and benchmarking
  • Reasoning with data streams
    • New stream reasoning algorithms
    • Incremental reasoning on dynamic ontologies
    • Temporal logics for reasoning over Semantic streams
    • Multicore scalable stream reasoning
  • Applications of stream processing
    • Semantic sensor networks
    • Social network streams and microposts
    • Stream processing in the Internet of Things
    • Smart cities
    • Activity streams
