The RIA094 conference is being held as electronic informa­tion processing is undergoing a profound revolution. At work or at home, digital access to electronic information is finally becoming a mass phenomenon.

Until now , only a relatively restricted number of people, researchers mostly, have had access to a limited number of data bases. Today, not only the quantity of information but its diversity have become factors that everyone must deal with. Data is becoming more available but is scattered over heterogeneous technical and social networks, managed in a distributed fashion with varied methods and aims. The information seeker is confronted with new challenges, and must develop new work habits as he or she directly tracks the possibilities of multishaped, large and evolving data­bases.

ln this light, RIAO has adopted a different approach and a different presentation of product demonstrations. Horizontal application areas giving a wide view of full applications within a domain will be presented in conjunc­tion with vertical enabling technologies that may be applied to any domain.

ln order to develop this new approach, more fully, we have extended the period for accepting new demonstration par­ticipants until September 1, 1994.

Three main horizontal sectors have been selected as demonstration areas: Medicine, Space and Art.


As Health Care Reforms are being initiated in Europe and in the US, much attention is being given to the future raIe of medical computing and telecommunications. At RIA094 recent developments relating to the Electronic Health Record of the future will be demonstrated.

Some of the applications and themes presented:

«The Visible Human» project from the National Library of Medicine.

Tools for identifying shapes in medical images, extracting information dynamically from sequences of 2D images (MIT Multimedia Lab).

Telemedicine with demonstrations from Europe via the World Wide Web.

Also electronic data interchange through standardized mes­sages, communication of medical images, the ultimate medical workstation.


Space and aeronautic technologies have created large quan­tities of image data and vast stores of technical documenta­tion. Information solutions in these areas will be demons­trated via applications such as:

Spot Images'database of 3.5 million satellite photos, enri­ched at a rate of 2.000 images a day.

Jouve will present a demonstration of its European­-American application using CALS and SGML in technical documentation and their impact on searching for informa­tion.


Virtual museum projects are numerous ail over the world, as methods are being explored to produce Art databases, interfaces and research engines. Some applications to be presented:

The NARCISSE project in the IMPACT program: Network of Art Research and Computer Image Systems in Europe.

The RAMA project in the European Race program : Remote Access to Museum Archives.

The San Francisco Museum of Art has recently developed a product entitled «American Visions».


Demonstrations of new and innovative functions in the fields of Libraries and Legal Fields will also be shown.

A demonstration will be given on the Tax Documentation Service containing legislation, interpretation and case law related to the Italian Taxation Domain, daily accessed by a very large number of users at ail relevant Public Administration sites in Italy through a large private net­work and duly updated by means of an internal text acquisition and indexing process. Relevant functionalities such as query expansion/restriction and textual navigation as well as usage of specific dictionaries will be shown.


As well as the presentation of the above horizontal applica­tion fields, vertical axes of enabling technologies will also be presented at RlA094.

Some of the best advanced products in the following fields will be present in the Product Demonstration section of RlA094. A same pie from each field is given.

Information Retrieval: with demonstrations by path setters such as Fulcrum, CIaritech ...

Software tools : Xerox Linguistic Tools; SGML information structuring tools; and other information management soft­ware.

Networks Services: GROUPLENS news filtering from MIT and University of Minnesota, and others

CD-ROM: SGML television dictionaries; from Italy, the Media Music system of navigation in a musical database.

Interfaces: group requests; navigational assistance; intelligent agents.

The Organizers of RIA094 are still communicating with a number of further applications and product developers who will be present at the conference.

The final list of the demonstrations will be available on September 10, 1994 and will be mailed on request and sent to participants who have mailed their registration form.
