Open Data: Gold Without Rush

When you need data from the past, it is too late to start collecting it. If you need satellite data, it is unlikely that you can have your own sensors in the space. Working with open data is sometimes cheaper than with market vendor data. But most open data is not processed. We made the investment to clean it for you.

Blog: Why is it so hard to work with it?

Our new, vertical observatories bring ESG and antitrust solutions from our domain-specific observatories. The competition observatory is in an early, conceptual phase. We are currently making progress with the ESG reporting issue, which overlap, for example, in providing evidence against greenwashing.

Link Unconnected, Hard-to-use Data

Just weeks before the tragic, but sadly predictable Belgian floods we connected some open, but unprocessed opinion poll data about the perception of flood risk, hydrological data about the actual risk of flood, and public finance data in the extremely decentralized country.

The data has been there, but it was not in a form that public policymakers, insurers of NGOs could have used directly. We are looking for partners to create similar use cases with for computational antitrust researchers or practitioners.

Looking for partners

We are looking for partners within the Dutch AI Coalition Culture and Media Working Group and similar organizations to integrate our data observatories into global knowledge graphs and to use them deploy trustworthy AI. ☛ blogspot ☛ slides

Participating in open source is often a highly collaborative experience. We’re encouraged to create in public view, and we’re incentivize to welcome contributions of all kinds from people around the world. This makes the practice of open source as much social as it is technical. ☛ slides

Applications

Smart Policy Documents

Stop uploading your work onto the web 2.0 in a pdf, epub, or word file. Build a self-refreshing resource that re-refreshes the statistics, legal texts, tables, visualizations, footnotes and bibliography instead. This way you’ll have a greater impact: you’ll connect to web 3.0 of the global knowledge graphs, and your work can be reused much better.

Re-visiting the digitisation of cultural heritage: What, how and why?

OpenMuse brings together music industry stakeholders and researchers from 12 European countries. Our partners represent the diversity of the industry, as well as the shared need to find financially, socially, and environmentally sustainable policy and business models in multiple, sometimes-fragmented streams (e.g., live music, composers/publishers, and recordings with producers and performers).

Music Eviota

We enable small music organisations to adopt evidence-based sustainability reporting for all environmental and social matters, prioritising greenhouse gas emissions where harmonised methodologies and benchmarks already exist.

Open Policy Analysis

Open Policy Analysis is an approach to policy analysis wherein data, code, materials, and clear accounts of methodological decisions are made freely available to facilitate collaboration, discussion, and reuse.

Open Music Europe

Open Music Europe brings together music industry stakeholders and researchers from 12 European countries. Our partners represent the diversity of the industry, as well as the shared need to find financially, socially, and environmentally sustainable policy and business models in multiple, sometimes-fragmented streams (e.g., live music, composers/publishers, and recordings with producers and performers).

Listen Local

Listen Local is a trustworthy, ethical AI-powered system that aims to help great artists in small organizations and small countries using big data. We want to make sure that audiences are not only recommended global superhits, but locally relevant music, too. At present, corporate algorithms fail to connect listeners in small countries with music from the local scene - with artists whom the listener can easily see perform live in local venues, who sing in the listener’s language and who connect with the listener’s feelings and experiences.

Music Creators' Earning Project

Our Digital Music Observatory contributed to the Music Creators’ Earnings in the Streaming Era project with understanding the level of justified and unjustified differences in rightsholder earnings, and putting them into a broader music economy context. The entire research paper is published by the UK Intellectual Property office, and we made the details of our analysis available in a joint publication.

CEEMID was multi-country project that was a predecessor of Reprex’s Digital Music Observatory.

Ensuring the Visibility and Accessibility of European Creative Content on the World Market: The Need for Copyright Data Improvement in the Light of New Technologies

While the US have already taken steps to provide an integrated data space for music as of 1 January 2021, the EU is facing major obstacles not only in the field of music but also in other creative industry sectors. Weighing costs and benefits, there can be little doubt that new data improvement initiatives and sufficient investment in a better copyright data infrastructure should play a central role in EU copyright policy. A trade-off between data harmonisation and interoperability on the one hand, and transparency and accountability of content recommender systems on the other, could pave the way for successful new initiatives.

Feasibility Study On Promoting Slovak Music In Slovakia & Abroad

Why are the total market shares of Slovak music relatively low both on the domestic and the foreign markets? How can we measure the market share of the Slovak music in the domestic and foreign markets? We offer some answers and solution based on empirical research and with the creation of a database and an AI application."

Can scholarly pirate libraries bridge the knowledge access gap? An empirical study on the structural conditions of book piracy in global and European academia

The topic of the paper is Library Genesis (LG), the biggest piratical scholarly library on the internet, which provides copyright infringing access to more than 2.5 million scientific monographs, edited volumes, and textbooks. The paper uses advanced statistical methods to explain why researchers around the globe use copyright infringing knowledge resources. The analysis is based on a huge usage dataset from LG, as well as data from the World Bank, Eurostat, and Eurobarometer, to identify the role of macroeconomic factors, such as R&D and higher education spending, GDP, researcher density in scholarly copyright infringing activities.
