Science today is difficult to imagine without a strong IT component. In Europe science that depends on IT is called eScience. IT infrastructures that support eScience are called e-Infrastructures. There is a long tradition to develop e-Infrastructures in Europe, and to try to connect them into continent wide e-Infrastructures. This to allow reasearchers from different countries to work together using the same computers.
The Knowledge Base provides insight into the complex e-Infrastructures, by providing overviews of projects, e-Infarstructures, and organisations, all in one big data graph. You can explore this by moving around the graph, gaining more udnerstanding of the complexe relations. We provide several starting pages that focus in different aspect as doors that unlock new rooms of information.
e-Infrastructures Knowledge Base gets a new look
The e-IRG Knowledge Base website, that contains information about European e-Infrastructures - including HPC - has got a new look. This makes it easier to browse the thousands of information items about projects, organisations, countries and national nodes of international organisations. The underlying graph database and content of the Knowledge Base was already completely renewed last year.
The content of the Knowledge Base is updated regularly. Recently, we added the country delegates of e-IRG and the members of the EuroHPC Governing Board.
The Knowledge Base website contains several windows on the 22.000+ indo items in the Knowledge Base.
- Projects: lists all the Horizon 2020 projects related to e-Infrastructures and HPC. For each project you can dig deeper and get info on the partner organisations, funding, research topic
- Documents: a document library with the main documents related to e-Infrastructures, with a short description and link to the original document
- Calendar: an e-Infrastructure calendar of main events
- National Nodes: there are many international research organisations with members in each country. We list most of them. (If an organisation is missing, please let us know.)
- Countries: provides an overview of European countries. For each country we describe the national node of international organisations, the NREN, the main supercomputer centres, whether the country is member of EuroHPC and much more.
The e-IRG Knowledge Base provides factual information about e-Infrastructures and related areas such as HPC and Research Infrastructures with a strong IT component. It is intended to be used by for instance the e-IRG in their policy making process. It is an element of evidence based policy making.
The facts, compiled by the Knowledge Base are taken from many Internet based sources. We use reliable primary sources only. For instance, when looking at who is member of the PLAN-E organisation, we go to the PLAN-E organisation's presence on the Internet.
To be able to present more than just lists, we use knowledge management techniques to be able to represent the information gathered from these many sources in such a way it can be combined. For instance, an organisation like "Forschungszentrum Jülich" participates in projects as a partner, houses supercomputers and is national node of several international organisations. We try to capture that automatically. The way we do that is by using unique identifiers for topics. The Forschungszentrum Jülich for instance has a specific partner code in European projects, that uniquely identifies the organisation. The centre also has another, unique code in the TOP500 list. And it has a unique domain name on the Internet: http://fz-juelich.de/. By aligning these three, we can collect a lot of information about the centre.
The automatic tools do a good job. However for humans it seems some of the collected information could be easily improved. For instance, for the Jülich centre, there are (at least) three different names used on the Internet: "Forschungszentrum Jülich", "Forschungszentrum Juelich (FZJ)", "Forschungszentrum Julich Gmbh". We just collect these names as "facts from the Internet".
The content of the Knowledge Base changes over time, because the content of the sources changes over time. We do not maintain archives.
Browsing the Knowledge graph
The projects, national nodes, and countries tabs provide further menus (on the left) that make it easier to dig deeper in the information.
That interface provides an overview of all the topics and relations inside the Knowledge Base graph. So you can click on topics, see the relations (called associations in Topic Maps) and click on them to see the related topics. Every topic also can have several Properties (called occurrences). We try to hide very specific Topic Maps technical terms from this view.
The current browser view contains four main menu headings (on the left of each page). These are provided as main starting points for users to allow them to enter the graph database. The menus reflect the main points of interest to the e-Infrastructure community today. So they will change in the future.
The "Knowledge Base" menu shows a list of organisations active in the area. This includes partners of H2020 projects, and HPC centres with TOP500 supercomputers. The "all projects" submenu lists all projects in the area. Currently, only H2020 projects are included. Through the country submenu one can drill down to the information related to each European country.
The second menu on the left side "HPC Analysis" shows some useful overviews related to HPC. With the developments around EuroHPC, there is a lot of interest in information about HPC in Europe.
In "HPC projects funded under Horizon 2020": we give an overview of all HPC related projects that are funded under Horizon 2020. This includes projects for specific HPC topics, but also HPC projects funded under other parts of H2020. Because we use here mainly the data from the European Open Data portal, the very latest projects are not always included yet. The Open Data portal sometimes lags a bit behind the contracts that already have been signed.
The list "Organisations with most funded H2020 HPC projects" lists the organisations with most funded HPC projects. We cut off the list at 5 projects. In the current list there are 35 organisations with 5 or more projects.
The EuroHPC members item provides a list of the countries that are member of the EuroHPC Joint Undertaking. From the list one can click further down to country details.
The e-Infrastructures menu section provides three useful lists as entries into the e-Infrastructures world:
"e-Infrastructure projects funded under Horizon 2020" lists all the funded H2020 projects. As some projects are both HPC and e-Infrastructures related, there is some overlap with the list of HPC projects. We also show the project budget for each project in the list. The individual project page gives much more information.
The "Organisations with most funded H2020 e-Infrastructure projects" lists the organisations in Europe that participate in at least 5 e-Infrastructure projects. There are 50 listed, which is more than under HPC. Also the number 1 on the list has fewer projects than the one on the HPC list. This shows the e-Infrastructure community is broader than the HPC community (measured in number of projects).
One of the topics of interest for the e-IRG (and the e-Infrastructure community) is the proliferation of international organisations in e-Infrastructures and related research infrastructures that have national nodes with many European countries. We list from 20 organisations the countries and in the country the organisations that act as national nodes of international e-Infrastructure related organisations.
The section on KPI analysis can be used to analyse Key Performance Indicators of selected e-Infrastructure projects.
The front end interface is a browsing interface only. There is a very simple facility that allows to reference each topic in the Knowledge Base if you know the subject identifier of the topic.
