TAS Data Collector in action 2

TAS Data Collector for gathering procurement data

TAS Data Collector has been specifically designed to enable collecting content available on the World Wide Web. These contents can serve as a basis for data provision, business decision making, scientific and research work, and the compilation of open data.

Online data collection plays an extremely important role in a number of areas, including significant projects such as DIGIWHIST, which aims to collect public procurement data by country.



The original aim of DIGIWHIST was to build a platform that can analyze procurement data from 35 European countries in various languages. During the years, however, the list has been expanded with further countries from Africa and Latin America. In addition, a whistleblower platform has also been implemented during the project.

As part of the project, Precognox has collected public procurement data and processed them using the DIGIWHIST framework. Data from Tanzania, Romania, Poland, Mexico, Kenya and Uruguay have been collected so far, among other countries. Brazilian public procurement data is currently being collected.

Making public tenders more transparent

As a result of the project, it is possible for everyone on the Opentender page to view the data on individual national portals (by selecting the given country) or explore all available data.
This is how data collection of procurement data makes public tenders more transparent.

Be as successful as the DIGIWHIST project

DIGIWHIST is a good example of how useful and successful a data collection project can be. In addition, the tasks mentioned at DIGIWHIST can be provided for all TAS Data Collector projects.
