Assessing data quality in open data: A case study

This article focuses on measuring the data quality extracted from the API www.datos.gov.co in the area of contracts. This platform allows public entities obey law 1712 of 2014 [2] but this does not have a validation system of minimum data quality. Three metrics are taken as a reference: completeness, traceability and compliance. The measuring of the metrics is done with a software called RapidMiner. This software allows to do data mining, in this specific case the processes for the measuring of the data stored are done and thus determine if the platform www.datos.gov.co has problems. For the programming of the prototype spiral methodology [7] is used. Calculations is created in each phase. Within the data found, serious inconsistencies are found within the platform and within the data, recalling the law 1712 of 2014, it says that the public data must be complete, which shows a breach of it.
