CALL FOR PAPERS: 5th Workshop on Managing the Evolution and Preservation of the Data Web - MEPDaW 2019

Co-located with The Web Conference 2019, San Francisco

Deadline Submission: 6th February 2019
Workshop: 14th May 2019


There is a vast and rapidly increasing quantity of scientific, corporate, government, and crowd-sourced data published on the emerging Data Web. Moreover, knowledge graphs have emerged as scalable knowledge models for integrating data collected from heterogeneous data sources, e.g., Data Web, and representing the meaning of these data and their properties. Knowledge graphs enable the modeling of facts that correspond to items of data, knowledge, or actionable insights, as well as the relations among these facts. The wide amount of sources of data and knowledge, offers a great potential for building innovative products and services that create new value; they are expected to foster active citizenship (e.g., around topics of journalism, greenhouse gas emissions, food supply-chains, smart mobility) and world-wide research according to the “fourth paradigm of science”.

Open access datasets are publicly available on the Web. The traditional way of digitally preserving them by “locking them away” for future use, conflicts with their evolution. There are a number of approaches and frameworks that manage a full life-cycle of the Data Web and knowledge graphs. More specifically, these techniques are expected to tackle major issues such as the synchronisation problem (how to monitor changes), the curation problem (how to repair data imperfections and add value over time), the appraisal problem (how to assess the quality of a source of data or knowledge), the citation and provenance problem (how to cite a particular version, how to keep the lineage/provenance), the archiving problem (how to retrieve the most recent or a particular version of a source), and the sustainability problem (how to support preservation at scale, ensuring long-term access).

This workshop targets one of the emerging and fundamental problems in the Web, specifically the management and preservation of evolving knowledge graphs. This topic is of particular relevance to The Web Conference since it raises awareness of the many research challenges for preserving and managing knowledge graphs that evolve over time. Fostering active usage of such evolving knowledge graphs requires further research advances on topics such as storage, synchronisation, change representation and querying. Solutions to these problems correspond to main subjects of interests of the workshop.

* User interfaces for exploring evolving knowledge graphs
* Visualisation of quality in knowledge graphs

- Preservation of Evolving Knowledge Graphs:
* Digital preservation
* Preservation of context, provenance and background knowledge
* Efficient and effective solutions for preserving evolving knowledge graphs
* Models for representing provenance and evolution

- Quality of Evolving Knowledge Graphs:
* Quality assessment and validation
* Machine Learning based quality assessment
* Quality trends and prediction in evolving knowledge graphs
* Hybrid approaches for knowledge graph curation

- Evaluation of Knowledge Graph Evolution:
* Benchmarks for managing, predicting, and curating evolution
* Real-world applications of evolving knowledge graphs
* Automatic and human-based techniques for evaluating evolving knowledge graph
* Creation of training datasets for evaluation of evolving knowledge graphs


We envision four types of submissions in order to cover the entire spectrum from mature research papers to novel ideas/datasets and industry technical talks:

A) Research Papers (max 10 pages), presenting novel scientific research addressing the topics of the workshop.

B) Resource Papers (max 10 pages), presenting functional systems or datasets relevant to the community.

C) Position Papers, Demo papers (max 5 pages), encouraging papers describing significant work in progress, late breaking results or ideas of the domain.

D) Industry & Use Case Presentations (max 5 pages), in which industry experts can present and discuss practical solutions, use case prototypes, best practices, etc., at any stage of implementation.

The proceedings of the workshops will be published jointly with the conference proceedings. Papers must be submitted in PDF according to the ACM format published in the ACM guidelines (, selecting the generic “sigconf” sample. The PDF files must have all non-standard fonts embedded. Workshop papers must be self-contained and in English.

All papers should be submitted to


We will provide an award for the best research paper submitted. Selection criteria include the innovative nature of work, the importance and timeliness of the topic, and the overall readiness and quality of the writing.
