Semantic integration is the process of interrelating information from diverse sources. Examples include:

• Calendars and to do lists
• Email archives
• Physical, psychological, and social presence information
• Documents of all sorts
• Contacts (including social graphs)
• Search results
• Advertising and marketing

Semantic inegration organizes information from all these sources and delivers content that is most relevant to users. In this regard, semantics focuses on the organization of and action upon information by serving as a mediary between heterogeneous data sources which may conflict not only by structure but also context or value.
