Social Media & Informatics - Key Terms

When speaking in terms of Social Media and Informatics, there are key terms we need to keep in mind:

• Information Science
• Academic discipline that is interdisciplinary. Includes a human component (how it is used, organized, etc.)
• Ontology
• Structural framework for organizing information. Used in Artificial Intelligence systems and semantic web (tagging, social tagging)
• Here is a really good ontology of a Tweet.
• Technology
• Where Library Science and Information Science differ
• Information Science focuses on information in its broadest sense (user interaction)
• Library Science focuses on information within context of the library (physical and virtual)
• Informatics
• Academic Study of computing technologies
• Social Media
• Interaction among people - people who are creating and/or sharing information
• Here is a link to what posts to specific social media app/site means to the users
• How are libraries using social media? 

I have linked the more complex concepts to their wikipedia pages, which, while they are not the most official academic resource, are easy to understand and are written and edited for those without deep understanding of these general concepts.
