Scaling Taxonomies

Verity Announces New Content Classifier (with screenshot) "VCC is based on roles and rules. Roles include taxonomy experts, subject matter experts within the organization (e.g., chemists, engineers, human resources staff, etc.), editors, and publishers. The company says the workflow feature allows taxonomy and classification management to be distributed to subject matter experts who know the content, as well as to knowledge engineers who know and understand taxonomy development. Different people who serve different roles are assigned different permissions to alter categories. The company claims that VCC is the only software that enables such real-time collaboration between knowledge workers and subject experts.

VCC uses rules to define how documents should be classified. Once taxonomies have been set up, VCC automatically classifies new documents as spiders discover them. The customer can control automatic classification by defining how well VCC thinks a document matches a category. For instance, if VCC’s confidence level for a candidate category exceeds 70 percent, then automatically publish it into that category; if not, route the decision to an assigned knowledge worker. Verity calls this “automated classification with manual oversight.”

Verity worked with DuPont to develop VCC. Whitney said the company uses VCC to manage a 25,000 node taxonomy. Internal users include “everyone from a bench chemist to a knowledge engineer—whoever.” He said VCC provides DuPont with “frictionless review between highly specialized knowledge workers, many with PhDs, and the knowledge engineering staff.”"
