Mergeflow data sets

Currently, Mergeflow collects ca. 15,000 new documents every day. This is done fully automatically, 24/7, and includes news, patents, science publications, blog posts, press releases, clinical trials, and other data sets and sources (see below for details).

Mergeflow collects data sets from across various types of sources, most of them via the web. While some of these sources provide data collection interfaces (APIs) for their contents, most sources do not, and require us to build customized crawlers.

All the data collected by Mergeflow are raw, unstructured text data. We do not rely on structured third-party databases, e.g. for market or investment data. Instead, all these data are extracted from text, via natural language processing, semantic modeling, machine learning, and other methods.

You can use Mergeflow's data sets for better search strategies. We describe how you can do this in our blog article, 'How to get better search results for tech discovery'.

Scientific Publications

Research papers, conference proceedings, and preprints from across different disciplines. This includes databases such as arxiv and PubMed.

  • Ca. 30,000 new documents / week.
  • Updated every 2 hours.


Patent publications from all worldwide patent offices, collected and provided by the European Patent Office. Patents are bundled by families. This means that Mergeflow counts patent families rather than individual patent publications (the number of individual patent publications is a lot higher since patent families bundle individual patent publications). Mergeflow first collects each patent in its original form and language, and then replaces non-English texts by the English version as soon as it becomes available via the European Patent Office.
