Special Issue on the 9th French-Speaking Workshop on Data Warehousing and OLAP and 1st Workshop on Social BI (Guest Editorial Preface)

The planetary success of social networks and the widespread diffusion of portable devices has resulted in the accumulation of enormous amounts of social content, that includes geolocation, preferences, opinions, news, articles, etc. Social Business Intelligence (SBI) is the discipline of effectively and efficiently combining this social content with corporate data to let decision-makers analyze the trends and moods perceived from the environment. The First International Workshop on Social Business Intelligence (SoBI) was held in Genoa, Italy, Sept. 1, 2013, in conjunction with the 17th East-European Conference on Advances in Databases and Information Systems (ADBIS 2013), and it successfully put together researchers and practitioners coming from different areas related to SBI for sharing their findings and cross-fertilizing their researches.
