Nowadays, in a broad range of application areas, the daily data production has reached unprecedented levels. These data origin from multiple sources, such as documental sources, social media posts, digital pictures and videos and so on.

The technical and scientific issues related to the data booming have been designated as the “Big Data†challenges. To deal with big data analysis, innovative algorithms and data mining tools are needed in order to extract information and discover knowledge from the continuous and increasing data growing.

In most of data mining methods, the data volume and variety directly affect computational load.

In this paper, we consider a strategic field like the e-Government one. We illustrate the strategies and the methodologies for big data processing and document management.
