Abstract

The publication of data by governments is increasing yearly with instauration of Open Government Data (OGD) initiatives around the world. These have materialized into public policies and their objective is to allow citizens and other collectives to access the data that previously were only accessible by public administrations. Most of the times, this data is released in a portal with a huge amount of separated tables with no explicit relations between them nor with a way to integrate them with the everyday work of the public institutions. This makes them very complicated for the extraction of processed information to interested citizens and other interested parties. The objective of this project is to improve the OGD by creating a new layer on top of these isolated resources. In particular, two sources of data have been considered: the Catalan OGD and the Diari Oficial de la Generalitat de Catalunya (DOGC). After extracting and integrating these data, a software tool has been developed that makes possible for a user to query the data according to different criteria. The result of a query is an interactive network visualization composed of nodes that correspond to entities and edges that represent some form of relation between the entities. Finally, a user case of this tool is described in which the software can be used to extract useful knowledge.
