Open Data Integration - Visualization as an Asset

Since several years, even some decades, a major problem in computer sciences is directly linked with data integration. When it becomes necessary to process information coming from different data sources, several problems may appear turning the process of integration more difficult to be 
 
accomplished. Nowadays, more and more information is flowing and is provided into the Web - Data Integration became even more important. The emerging trend of Open Data (OD) is an active actor for this event. Integrating data coming from public entities can be a difficult process. Large 
 
quantities of datasets are made available. However, an important level of heterogeneity may also exist: Datasets can be on different formats, forms and shapes. If the fact of being possible to access this information can be an important asset, it also can be completely useless if it is not 
 
possible to interpret so it can be used. Information Visualization may be an important tool to help the OD integration process. This paper presents problems and barriers which can be encountered on the OD integration process. The paper also describes how Information Visualization can be used to facilitate the integration of OD and turn the procedure more effective, friendlier, and faster.
