PortBlue Technology

PortBlue's technology is based on a mixture of artificial intelligence (AI) techniques, including forward and backward chaining rules, and reasoning using uncertainty. This concept allows for arbitrary-dimensional data, dynamic forms of presentation, and a straightforward question and response presentation.

PortBlue's technology platform consists of four basic levels:

Knowledge Architecture enhances usability

To minimize the burdens and costs of knowledge engineering, PortBlue has designed a Knowledge Architecture that allows users to capture expertise at the knowledge element and react flexibly to the differing characteristics of a particular domain of knowledge without sacrificing the speed and economies of scale that support PortBlue's business model. The knowledge architecture also decouples technology innovation from future module development, allowing PortBlue to create all the elements of a module without requiring the services of programmers, web page designers or other technical staff.
PortBlue's Knowledge Architecture combines business decision logic and artificial intelligence, two methods that are represented in its "layers":

• The presentation layer, reflecting a hypothesis-driven approach to decision making, uses a page-based navigation system where module content is specified on a page-by-page basis.
• The decision logic layer is based on forward and backward chaining artificial intelligence methodologies to dynamically adjust to the particulars of a given decision or user. At each point/time when new data enters the knowledge engine either from clients, external feeds, or internal computation, the decision tree is re-evaluated to determine the optimal path to a decision or through a process.

These two layers interact in various ways as customers use a module, creating updated results and dynamic navigation, which lead users to critical insights.

Knowledge Capture Tool (KCT)

The user's primary interface with PortBlue's Knowledge Architecture is the Knowledge Capture Tool (KCT). The KCT is the centerpiece of PortBlue's technology and changes the economics of knowledge capture and transmission. The KCT allows users to manufacture modules by defining a logical structure, creating the logical connection formulas that capture data interrelationships and relevance filters that present information dynamically based on user inputs, and specifying data elements to capture user information.
