CFP: JWS Special Issue on Representation Learning for the Semantic Web

Special Issue of the JWS on
Representation Learning for the Semantic Web

The Journal of Web Semantics invites submissions for a special issue on representation learning for the Semantic Web,  to be edited by Heiko Paulheim, Volker Tresp and Zhiyuan Liu.

Submissions are due by 30th November 2017.

In the past years, learning vector space embeddings has rapidly gained attention, first in the natural language processing community with the advent of word2vec, and more recently also in the Semantic Web community, e.g., with the adaptations RDF2vec or node2vec, as well as the RESCAL/HolE and Trans* family. Their properties - the representation of entities in a dense vector space, the proximity of semantically related entities, and the preservation of the direction of semantic relations - make them interesting for many applications.
There are various ways of creating such embeddings. They range from applying the word2vec paradigm to sequences derived from graphs to translation learning and tensor factorization. Those methods differ both in their scalability on different types of input datasets, as well as in the characteristics of the resulting embeddings.
At the same time, novel use cases for embeddings of Semantic Web data are discussed. Those applications range from Semantic Web specific use cases, such as link prediction in knowledge graphs, to general applications, such as recommender systems and decision support systems. In many of those fields, approaches leveraging embeddings have recently been reported to outperform traditional techniques.
The aim of this special issue is to present latest advances in neural embeddings for the Semantic Web, as well as novel applications. Topics of submissions include, but are not limited to:

  • Novel methods for learning embeddings
  • Theory of representation learning for the Semantic Web
  • Embeddings of ontologies and knowledge graphs
  • Joint embeddings of Semantic Web and non-Semantic Web data (e.g., text, media, ...)
  • Paradigms for sharing and reusing embeddings
  • Embedding systems for modeling human memories
  • Scalability of embedding learning
  • Implementations
  • Reusable embeddings for popular Semantic Web resources, e.g., DBpedia or Wikidata
  • Software frameworks for learning and using embeddings
  • Experimental studies and benchmarks
  • Application areas of embeddings, e.g. recommender systems, entity search or named entity disambiguation

    Submission Guidelines

    The Journal of Web Semantics solicits original scientific contributions of high quality. Following the overall mission of the journal, we emphasize the publication of papers that combine theories, methods and experiments from different subject areas in order to deliver innovative semantic methods and applications. The publication of large-scale experiments and their analysis is also encouraged to clearly illustrate scenarios and methods that introduce semantics into existing Web interfaces, contents and services.

    Submission of your manuscript is welcome provided that it, or any translation of it, has not been copyrighted or published and is not being submitted for publication elsewhere. Manuscripts should be prepared for publication in accordance with instructions given in the JWS guide for authors. The submission and review process will be carried out using Elsevier's Web-based EES systemPlease select “SI:Embeddings” when reaching the Article Type selection.

    Upon acceptance of an article, the author(s) will be asked to transfer copyright of the article to the publisher. This transfer will ensure the widest possible dissemination of information. Elsevier's liberal preprint policy permits authors and their institutions to host preprints on their web sites. Preprints of the articles will be made freely accessible on the JWS preprint server. Final copies of accepted publications will appear in print and at Elsevier's archival online server.
