Social graph A map of people and how they’re connected. In relational form, the social graph has interesting but limited utility. In Resource Description Framework (RDF) graph form, however, it can be a powerful means of navigation. In this form, the social graph can be connected to a larger knowledge graph that can help make the whole more intelligible.
Interest graph A map of interests and how they’re interrelated. Following interests, rather than just people, can be a way to reduce information overload. When connected to the social graph and the larger knowledge graph via RDF, a map of interests can make content much easier to browse or to search and retrieve.
Social media Blog, microblog, wiki, and other kinds of many-to-many postings on the public web. Contrast social media with collaboration-generated media inside the enterprise, a very different form of online information. The latter media are also evolving to a many-to-many paradigm with the help of an activity stream, but that’s where the similarity ends.
Sense making
Gaining an initial understanding. Enterprise teams need to engage in sense making as part of any major business process. The ad hoc nature of sense making contrasts with more predictable kinds of execution, the kinds of tasks addressed by transactional systems. Collaboration systems attempt to make sense making easier.
How teams work together to create value. Technology, even the web, hasn’t had much impact on collaboration over the past 20 years yet. Changing that situation is becoming more feasible, but only with the right vision and long-term commitment.
