Call for Papers

The mission of ESWC is to bring together researchers and practitioners dealing with different aspects of semantic technologies. Building on its past success, ESWC is seeking to broaden its focus to span other relevant research areas in which semantics in a Web context plays an important role. The goal of the Semantic Web is to create a Web of knowledge and services in which the semantics of content is made explicit and content is linked to both other content and services. This network of knowledge-based functionality will weave together a large network of human knowledge, and make this knowledge machine-processable to support intelligent behaviour by machines. It will support novel applications allowing to combine content from heterogeneous sites in unforeseen ways and support enhanced matching between users needs and content.

Creating such an interlinked Web of knowledge which spans unstructured, RDF as well as multimedia content and services requires the collaboration of many disciplines, including but not limited to: Artificial Intelligence, Natural Language Processing, Database and Information Systems, Information Retrieval, Machine Learning, Multimedia, Distributed Systems, Social Networks, Web Engineering, and Web Science.

In addition to the research and in-use tracks, we have furthermore introduced two special tracks this year, putting particular emphasis on inter-disciplinary research topics and areas that show the potential of exciting synergies for the future.

Research Track:
Social Web and Web Science


The widespread uptake of social functionality by web applications has lead to the creation of masses of social data, however such data is often provided using platform-dependent schemas and vocabularies, thereby limiting automated reuse. Enrichment of such data with common semantics would overcome such limitations and enable machine-readability and interpretation. Realising this goal requires research, not only into the semantic description of social data, but also to provide evidence of its utility, for example through intelligent behaviour analysis, user profiling and community analysis. To this end we invite submissions of state of the art work within, but not entirely limited to, the following topic areas:


  • Schemas/ontologies for social data and reconciling social semantics with format semantics
  • Semantic enrichment of the Social Web (RDFa, microdata) and Linked Data on the Social Web
  • Querying, mining and analysis of social semantic data and dynamics
  • Semantic network and community analysis and supporting community lifecycles
  • Social Semantics in micro (user profiles, behaviours, messages, etc.) and macro (social constructs, metrics, etc.) levels
  • Semantics in mobile social networks and mobile access to social data on the web
  • Web users as virtual and physical sensors, crawlers, etc. for a ubiquitous social semantic web
  • Social Semantic Web and the Internet of Things and reality augmented by the social semantic web
  • Semantically-enabled social platforms and applications: wikis, forums, portals, blogs and microblogs, etc
  • Reasoning and personalization based on semantics: recommendations, social navigation, collaborative search, social filtering, etc.
  • Privacy, policy and access control on Social Semantic Web
  • Provenance, reputation and trust on Social Semantic Web
  • Semantics for Human-based computation and vice-versa
  • Socialized semantic web applications: shared semantic desktop, collaborative knowledge creation, semantic bookmarking, etc.

Research Track:
Natural Language Processing


Although knowledge processing on the Semantic Web is inherently language-independent, human interaction with semantically structured and linked data will remain inherently language-based as this will still be done preferably by use of natural language input. The interface between natural language on the one hand and semantically structured data and knowledge on the other is therefore a major topic of Semantic Web research, which can be observed also by a general increase of NLP-related topics that are of relevance to this community. In particular we invite contributions that will advance the state of the art in:


  • Multilinguality and the Semantic Web / Web of Data
  • Natural language generation in a Semantic Web context
  • Natural language interfaces for Semantic Web applications
  • NLP for ontology matching, merging, alignment
  • Ontology learning and knowledge acquisition from text
  • NLP for Linked Data generation and use
  • Question answering on the Semantic Web / Web of Data
  • Use of ontologies / Linked Data in NLP
  • Ontology-based text classification and clustering
  • The ontology-lexicon interface
  • Ontology localisation
  • NLP for semantic search

Research Track:
Sensor and Mobile Web


The correct interpretation and analysis of the raw numerical values provided by pervasive sensor networks and mobile devices now featuring several sensors requires proper semantics support and contextual knowledge. This will enable better data representation, integration, and use, and further aids in coping with the inherently unreliable nature of the observations provided by sensor networks and mobile devices, affected by sensor noise, faults, and resource constraints. In this track we invite approaches dealing with combining sensor networks and/or mobile devices and semantic technologies for the purpose of management, interpretation and analysis of the observed environment, users' movements, activities, or social interactions. Contributions are expected to cover a wide range of related topics such as (a) identification of simple events or event streams by joining sensor data with background knowledge, (b) identification of complex events composed from several atomic sensed events based on background knowledge, (c) filtering, management, and interpretation of sensor and mobile data using contextual models, (d) creation of actuators and applications based on sensor data and background knowledge. We invite high-quality submissions related to (but not limited to) one or more of the following topics:


  • Architectures and middleware for the semantic sensor and mobile web
  • Context- and location-aware applications based on semantic technologies
  • Data models and querying solutions for the semantic sensor and mobile web
  • In-network data processing and filtering techniques based on locality, contextual and semantic knowledge
  • Linked data and mashups on the sensor and mobile web
  • Ontologies and rules for semantic sensor and mobile web
  • Use cases and applications demonstrating the use of semantic technologies for sensor and mobile web
  • Provenance of semantic data on the sensor and mobile web
  • Scalability and performance of semantic technologies on sensor and mobile web
  • Semantic data integration and fusion of heterogeneous sensor network data streams

Research Track:
Machine Learning


With the growing availability of Semantic Web Data, machine learning approaches ---in particular inductive learning methods--- are increasing in relevance. The prospect is that innovative approaches for (semi-) automatically building and enriching ontologies from information sources such as Linked Data, tagged data, social networks, and ontologies will increasingly support Semantic Web applications. Furthermore, inductive incremental learning techniques can perform reasoning at large scale beyond the limitations of deductive approaches. Finally, machine learning can deal with the intrinsic uncertainty in Web data containing incomplete and/or contradictory information. We invite high quality contributions from all areas of research that address the emerging data challenges.


  • Extraction and augmentation of ontological knowledge from (linked) data using statistical and inductive methods
  • Statistical machine learning in Linked Data
  • Inductive methods for ontology construction
  • Machine learning for ontology matching, instance matching, search and retrieval
  • Link prediction and recommendation engines
  • Machine learning method for handling uncertain knowledge

Special Track:
Digital Libraries and Cultural Heritage Track


Digital Libraries (DL) are fast becoming significant resources for the world’s knowledge. This is especially true in the Cultural Heritage (CH) sector, e.g., in Libraries, Archives and Museums, where large bodies of digital documents and metadata are being assembled and re-distributed through initiatives like But even though a lot content is already accessible via the visible Web, much more could be exploited, and better exploited using Semantic Web technology. Often, Digital Libraries focus on particular disciplinary and subject areas and constitute curated knowledge. Semantic Web techniques for digital libraries will therefore take advantage of much richer assumptions on domain-specific semantics, consistency and quality of content. Linked Data technology also offers unprecedented opportunities for data sharing and re-using, within the cultural domain itself, and across a wider range of sectors. Particular topics of relevance are:


  • DL/CH requirements for semantic technologies
  • Core ontologies and community-specific extensions, application profiles
  • Adequacy of metadata, schemata and ontologies to applications (e.g., answering research questions)
  • Deductions from complex data paths in semantic metadata relationships, such as detecting co-author clusters
  • Inferences between collection-level and item-level metadata – from wholes to parts and vice-versa
  • Querying of an ‘Open World’ of incomplete metadata
  • Metadata transformation and enrichment
  • Metadata integration and sharing
  • Authenticity, digital provenance and digital rights management, long-term preservation
  • Automatic or manual community-driven detection of co-reference to people, places, events, things
  • Applications of Linked Data in Libraries, Archives, Museums
  • Methodological contributions: best practices/lessons learnt for applying SW / Linked Data to large DLs

Special Track:
EGovernment: Using Semantics for Promoting Interoperability in the Public Sector


Public administration is considered the heaviest service industry as well as the most important information provider even in countries with relatively small public sectors. It is also a highly distributed "business", with hundreds or even thousands of different entities providing services and data to other public agencies, businesses and citizens. In this environment, promoting interoperability amongst all these various actors is considered vital for improving responsiveness, efficiency and reducing costs. The European Interoperability Framework introduced four layers of interoperability, technical, semantic, organizational and legal. With the current advancement and the availability of off-the-shelf solutions for addressing technical interoperability issues, the focus has been shifted to semantic interoperability, a layer that has recently received much attention by both researchers and practitioners. The special track focuses on contributions related to this specific interoperability layer. An indicative list of topics follows below:


  • Definitions, models and theory on semantic interoperability for eGovernment systems
  • Requirements, and challenges for semantic interoperability in eGovernment
  • Metadata standards, ontologies and vocabularies for eGovernment
  • Examples and experiences from national, regional, local projects and strategies to promote semantic interoperability
  • Linked Open Government Data
  • Semantic SOAs for eGovernment
  • Semantics and Social Software for eGovernment
  • Government 2.0 and semantics
  • Semantics in eParticipation and eConsultation
  • Interoperability maturity models and approaches
