Jim Spohrer sends along a link to a talk by Rob High, IBM Chief Technology Officer, Fellow and Vice President, Does a good job of discussing why Watson is cognitive, unique, and why it differs from previous attempts at delivering expertise. Non technical.
I ask: So how you convince a complex organization this uniqueness is useful, stable and scalable? Only through clear operational examples in varying contexts. That appears to be what they are working on.
IBM® Watson™ represents a first step into cognitive systems, a new era of computing. Watson builds on the current era of programmatic computing but differs in significant ways. The combination of the following capabilities makes Watson unique:
Natural language processing by helping to understand the complexities of unstructured data, which makes up as much as 80 percent of the data in the world today
Hypothesis generation and evaluation by applying advanced analytics to weigh and evaluate a panel of responses based on only relevant evidence
Dynamic learning by helping to improve learning based on outcomes to get smarter with each iteration and interaction
Although none of these capabilities alone are unique to Watson, the combination delivers a powerful solution:
To move beyond the constraints of programmatic computing
To move from reliance on structured, local data to unlock the world of global, unstructured data
To move from decision tree-driven, deterministic applications to probabilistic systems that co-evolve with their users
To move from keyword-based search that provides a list of locations where an answer might (or might not) be located, to an intuitive, conversational means of discovering a set of confidence-ranked responses
This IBM Redguide™ publication describes how Watson combines natural language processing, dynamic learning, and hypothesis generation and evaluation to give direct, confidence-based responses.
