NetWeaver
Click here to download NetWeaver Developer-Full Install.
This version of NetWeaver is Windows compatible (95, 98, 2000, NT, XP) and is distributed as fully functional annoyance-ware. Until it is registered, a reminder message will pop up at annoyingly random intervals. For more information about upgrading to the licensed version, please see EMDS Licensing.
The software provides graphic tools for constructing executable dependency networks that permit both forward and backward chaining reasoning and renders knowledge dependency networks with a fully executable graphic representation so that networks appear just like they would on a white board. Because the inference engine is integral, networks can be evaluated in real-time with nodes changing color to indicate their changing “trueness” levels. This ability to peer into the logical workings of a knowledge network greatly optimizes the knowledge engineering process by
-
providing the ability to run and evaluate freshly elicited knowledge in the presence of the domain expert,
-
enabling the knowledge engineer to trace the logic structure from data to conclusions and
-
allowing the knowledge engineer to quickly identify and edit errors and inconsistencies in the logic.
Knowledge base systems come in a variety of forms, but the dominant type currently in use are rule-based systems. Knowledge representation in NetWeaver, in contrast, is based on object-oriented fuzzy-logic networks which offer several significant advantages over the more traditional rule-based representation. Compared to rule-based knowledge bases, NetWeaver knowledge bases are easier to build, test, and maintain because the underlying object-based representation makes these types of knowledge bases very modular. The modularity of NetWeaver knowledge bases, in turn, allows the designer to gradually evolve complex knowledge bases from simpler ones in small, simple steps. Modularity also allows interactive knowledge base debugging at any and all stages of knowledge base development which expedites the develop process.
Finally, fuzzy logic provides a formal and complete calculus for knowledge representation that is less arbitrary than the confidence factor approach used in rule-based systems and much more parsimonious than bivalent rules.

Criterium DecisionPlus (CDP)
Click here to download CDP Student Version (6 MB, version3.0).
The student version may be downloaded by anyone - student or not. The "student" version of CDP has the same functionality as the full version, but limits model size to 20 data blocks. The full version of CDP 3.0 can handle up to 500 data blocks.
For more information about upgrading to the licensed version, please see EMDS Licensing.
Criterium DecisionPlus (CDP), is a multi-criterion decision analysis tool developed by InfoHarvest, Inc. that helps users manage decision-oriented data, make decisions, develop decision-making guidelines, and communicate their recommendations effectively. It software package provides visual support for brainstorming and hierarchy building for users making complex decisions among alternatives involving competing criteria. The software helps elicit user values through pair-wise comparisons, weights and tradeoffs interfaces. CDP provides contributions by weights, sensitivity to weights and tradeoffs analysis tools to help the user validate their decision model.. It supports the two leading methodologies for multi-criteria decision analysis, the Analytical Hierarchy Process (AHP) and the Simple Multi-Attribute Rating Technique (SMART). When used with large numbers of alternatives, such as river reaches in a riparian ecology, a CDP decision model provides an objective, transparent prioritization of the alternatives.

EMDS Licensing Informationn
Current versions of the EMDS extension (3.02 and 3.1) for ArcMap are in the public domain, and as such are available at no charge. We simply require that users complete the site registration. However, the NetWeaver and Criterium DecisionPlus components (used to build EMDS applications) are commercial products. Please read the section below that pertains to you.
USDA Forest Service Users
The Forest Service has licenses for 200 seats each for NetWeaver Developer and Criterium DecisionPlus (CDP).
To request a NetWeaver license, please email Keith Reynolds from a Forest Service IP address to obtain the agency's generic component of the license key. This two-part key is entered in the licensing dialog of NetWeaver, and then transmitted to the software developer, Rules of Thumb. Rules of Thumb will reply with a machine-specific three-part code to complete registration.
