Open Contracts

A crowdsourcing platform for searching and analyzing government contracts. It provides a much more usable interface to work with contracts of Slovak governmental organizations in comparison to the official government site. It downloads and processes over 300k scanned documents (over 1TB of raw data) in various formats from many sources and transforms them into an easily searchable format using full text and advanced faceted search. Contracts are automatically analyzed and assigned a score indicating how problematic the contract is. 此分析基于门户管理员管理的规则.
