CFP: Using Provenance in the Semantic Web

Journal of Web Semantics Special Issue on
Using Provenance in the Semantic Web
Editors: Yolanda Gil, University of Southern California’s Information Sciences Institute and Paul Groth, Free University of Amsterdam
The Web is a decentralized system full of information provided by diverse open sources of varying quality. For any given question there will be a multitude of answers offered, raising the need for assessing their relative value and for making decisions about what sources to trust. In order to make effective use of the Web, we routinely evaluate the information we get, the sources that provided it, and the processes that produced it. A trust layer was always present in the Web architecture, and Berners-Lee envisioned an “oh-yeah?” button in the browser to check the sources of an assertion. The Semantic Web raises these questions in the context of automated applications (e.g. reasoners, aggregators, or agents), whether trying to answer questions using the Linked Data cloud, use a mashup appropriately or determine trust on a social network. Therefore, provenance is an important aspect of the Web that becomes crucial in Semantic Web research.
This special issue on Using Provenance in the Semantic Web of the Journal of Web Semantics aims to collect representative research in handling provenance while using and reasoning about information and resources on the web. Provenance has been addressed in a variety of areas in computer science targeting specific contexts, such as databases and scientific workflows. Provenance is important in a variety of contexts, including open science, open government, and intellectual property and copyright. Provenance requirements must be understood for specific kinds of Web resources, such as documents, services, ontologies, workflows, and datasets.
We seek high quality submissions that describe recent projects, articulate research challenges, or put forward synergistic perspectives on provenance. We solicit submissions that advance the Semantic Web through exploiting provenance, addressing research issues including:
  • representing provenance
  • relating provenance to the underlying data and information
  • managing provenance in a distributed web
  • reasoning about trust based on provenance
  • handling incomplete provenance
  • taking advantage of the web’s structure for provenance
Submissions may focus on uses of provenance in the Semantic Web for:
  • linked data
  • social networking
  • data integration
  • inference from diverse sources
  • trust and proof
Papers may also focus on application areas, highlighting the challenges and benefits of using provenance:
  • provenance in open science
  • provenance in open government
  • provenance in copyright and intellectual property for documents
  • provenance in web publishing

Important Dates

We will aim at an efficient publication cycle in order to guarantee prompt availability of the published results. We will review papers on a rolling basis as they are submitted and explicitly encourage submissions well before the submission deadline. Submit papers online at the journal's Elsevier Web site.

cfp: Web-scale Semantic Information Processing

Web-scale Semantic Information Processing

Note revised dates
One of the greatest challenges for the Semantic Web is achieving web-scale. While the information retrieval community has developed successful strategies for coping with the scale of the web using statistical techniques, semantic web technologies are still struggling with scaling up to the web as such. This is in part due to the need to preserve the data’s structure and the need to perform various forms of reasoning in order to more effectively leverage the available information. The need to handle vast amounts of structured data on the web is now widely recognized and efforts like the Billion Triples Challenge have been launched to advance the state of the art with this respect.
For this special issue, we seek papers that present algorithms and architectures that help semantic web systems achieve any form of scalability possessed by contemporary, state-of-the-art web applications, including, but not limited to:
  • answering queries and/or reasoning with billions of triples
  • operating over hundreds of ontologies or schemas simultaneously
  • supporting hundreds of thousands of users and/or concurrently handling semantic web requests from thousands of users
Accepted papers will have to provide detailed descriptions of their algorithms, architectures, and data structures and include systematic empirical evaluations that clearly demonstrate their claims of scalability. Topics of interest include, but are not limited to:
  • semantic web search engines,
  • benchmark evaluations of the state-of-the-art systems
  • systems that process data streams from multiple sensors
  • parallel and distributed reasoning,

Special Issue on Semantic Web Dynamics

CALL FOR PAPERS Special Issue on Semantic Web Dynamics

Description

Recent years have witnessed the arrival of more and more semantically annotated data and related ontologies in the Semantic Web. For example, the linked data initiative has been very successful in making datasets available online, with a total of about 5 billion triples all together so far. While existing semantic tools and reasoning engines are year after year getting better in dealing with time invariant domain of ontological knowledge, supporting rapidly changing information has not yet attracted sufficient attention.
There are more and more heterogeneous and/or dynamic data types being created and which integration could lead to interesting applications and models (e.g. sensor data streams, geospatial information and imagery, financial transactions, news feeds, 3D models, engineering data, information for policy intelligence etc.). Current Stream Database Management Systems provide on the fly analysis of data streams, but they suffer several limitations: they cannot handle heterogeneous data streams originating from a variety of already deployed sensors; they cannot combine data streams with slowly evolving knowledge at query time; and they cannot perform reasoning tasks. And in the area of reasoning, while the problem of classical, time invariant domain of ontological knowledge has been extensively studied, the task of reasoning with rapidly changing information has been mostly neglected and constitutes a new challenge.
Furthermore, ontologies, just like any structure holding knowledge and information, need to be updated too: changes could be initiated because of a change in the world being modelled; or by a change in the users’ needs which would require a different conceptualization; or by the acquisition of knowledge previously unknown, unclassified or otherwise unavailable; or by the noticing of a design flaw in the original conceptualization. In all these cases, the representation of knowledge in the ontology should be modified so as to form a more accurate or adequate conceptualization of the domain.
This general issue of Semantic Web Dynamics includes difficulties from both practical and theoretical points of view, raising a variety of research questions and development challenges, such as how to support the ontology and data publishers in maintaining up-to-date, adequate representations; how to detect the need for evolution and changes; how to facilitate the integration of new, dynamic sources in existing datasets and ontologies; how to validate and evaluate the impact of the changes on semantic information; how to handle changes triggered from multiple sources and collaborative updates; and how to keep track of (possibly concurrent) versions of and ensure the delivery of up-to-date and valid knowledge.
