The Challenge

The second Network Verification Challenge (NVC) started in April 2014 and closed in Spring 2015. The networks have been reviewed and best performers were invited to a Jamboree held June 2015 in Barcelona, Spain. The updated version of the networks is available here for further review and enhancement.


Compete. Collaborate. Contribute.

Review and refine the networks to create a better set of open source, freely available biological network models for the scientific community. The models capture a wide range of pathophysiology related to human pulmonary biology curated from scientific literature in the Biological Expression Language.

Join the crowd as it unites to verify and enhance existing biological network models for use in research applications such as drug discovery, personnalized medecine and toxicological assessment. Challenge your peers and see in real time how you rank in the leaderboard. Join now and be part of this exciting challenge.

Why should you participate to the Network Verification Challenge (NVC)?

As participants, your main motivation to contribute in the sbv IMPROVER Network Verification Challenge is likely the desire to be part of a scientific community curating networks that describe biological processes in the lung, with a greater purpose to advance the field of systems biology.

In addition, you will:

  • contribute to writing peer-reviewed scientific publications describing the outcome of the challenge;
  • enhance your visibility and gain scientific recognition through a reputation engine;
  • grow your professional network by engaging with researchers from around the world;
  • gain early access to high-quality biological network models and download the published biological network models (providing that your have made significant contribution to the verification process);
  • learn new biology, including network representation techniques (OpenBEL)

What are the steps of the NVC?

  • Online crowd-verification – the scientific community participates in an online verification process to review, challenge and enhance network models of biological processes in the respiratory system;
  • Network jamboree – once the online verification process is finished, the most active challenge participants and domain experts may be invited to a face to face or a virtual meeting to review the results of the online verification process, examine disputed edges and evidence, and reflect on the future of network verification activities;
  • Network dissemination and continuous improvement – Based on the outcomes of the online verification and Jamboree, the biological network models will be finalized and published on this platform, and be available for continuous use and refinement (ongoing).

Steps in the sbv IMPROVER Network Verification Challenge

Get started

The series of videos below will give you in-depthinformation about the Network Verification Challenge 2:

  • BEL language and creation of network edges and nodes - The biological networks models included in the NVC have been scripted in the Biological Expression Language (BEL). You can learn BEL while interpreting the networks, and use it to add edges and nodes.
  • The online crowd-verification process - This tutorial on the online crowd-verification process describes the different types of actions on the biological network models that can be used for verification and to award reputation points.
  • Overview of the biological network models - This overview explains the biological network models that have been included in the NVC. It introduces the biological processes being modelled, the boundary conditions of the models, and the methodology used to build the models.
  • Webinars - A series of live sessions covering topics around this challenge. This allows you to deepen your knowledge and actively participate in discussions. Additionally, past webinars will be made available as videos.
  • More webinars.

In addition, on the Get started section, you can find step-by-step explanations on how to get started on the Challenge (create/manage an account, explore the networks, add edges and evidence, monitor activity, etc).
