An interesting discussion has started at LinkedIn around this possible answer:

All 5 elements of this formula have been questioned: Link

• Facts | Data | Information?
• Rules | Knowledge?
• “=” means no algorithms (off-the-shelf rule engines or other reasoning tools)
• Is “=” one- or two-directional? Knowing decisions can we point to facts and rules that led to them?
• Decisions (violations, inconsistency)?

• Meaning of “+” and intelligent glossaries
• Live events and time as an important dimension
• Learning from already made decisions (ever-learning loop)
• Explanations and human interaction
• ?
