NAVIGATOR

NOVATO, CALIF., MAY 20, 1996- Inference Corporation (Nasdaq: INFR) and
Verity, Inc. (Nasdaq: VRTY) today announced that Inference has signed an
OEM agreement to integrate Verity's powerful topic full-text search and
retrieval technology into Inference's CBR3 Content Navigator family of
products. CBR3 Content Navigator will use Verity's topic search technology
to provide an additional access method to retrieve and manage complete
documents, broadening the scope of information that users can be guided
through in order to solve problems or answer questions more quickly.

In a related press release, Inference announced CBR3 Content Navigator, the
first comprehensive content management and retrieval system, providing a
common index and retrieval method for the wide variety of unstructured
information in help desk, customer service, human resources, and telesales
and telemarketing organizations. The product family, scheduled for general
availability in Q4 1996, is designed to allow access to and management of
four levels of unstructured information, including cases containing
experiences, solutions and answers; document summaries and abstracts;
documents in a variety of formats in personal and corporate libraries; and
public domain and subscription information over the Internet.

"Verity's leading full-text search and retrieval technology provides
efficient access to documents, a key to delivering a comprehensive content
management and navigation system," said Pete Tierney, chairman, president,
and chief executive officer of the Inference Corporation. "We are looking
forward to using the Verity topic engine throughout our CBR3 Content
Navigator product line."

"This relationship will allow Inference's CBR3 Content Navigator customers
to use the proven CBR dialogue-based guided search paradigm to access
documents indexed using Verity's topic search technology, "said Philippe
Courtot, chairman and CEO of Verity, Inc. " In establishing this
relationship with Inference, we remain consistent in aligning ourselves
with industry leaders and furthering our 'topic everywhere' strategy"

CBR3 CONTENT NAVIGATOR FAMILY OF PRODUCTS

Inference's CBR3 Content Navigator products facilitate successful dialogue
with the customer. A Typical CBR3 Content Navigator session begins with a
description of the problem the user is having or the product a customer
wants to purchase. This is matched to descriptions of previously solved
problems or to product characteristics stored in the form of cases,
documents, or URLs that identify likely solutions and products. CBR3
Content Navigator products further guide the user or customers by posing a
set of questions that is used to further refine the search until a very
likely solution or product is presented. Because CBR3 Content Navigator
supports stand alone, file-server, client-server, Internet and Intranet
environments, companies have many options to deploy knowledge.
