Fourth ACM conference on Hypertext

Sponsored by SIGLINK, SIGIR, SIGOIS In cooperation with Politecnico di Milano, AICA, commission of European Communities, GMD, INRIA, NEC, NTT, LINK IT!, SIGCHI

November 30/December 4, 1992, Milano (Italy)


ECHT'92 is the second in a series of European conferences on Hypertext and Hypermedia in alternation with the U.S. based Hypertext conferences coordinated and sponsored by ACM. ECHT'92 is a major event where researchers, developers and users can meet around the theme of Hypertext and Hypermedia.

The broad applicability of Hypertext and Hypermedia as a primary technology in many domains and its efficiency as an information integrator has led to increased interest from industry as well as recognition from academia. By their very nature, Hypertext and Hypermedia are at the intersection of many fields, including computer science, cognitive science, education, and communication. They are also relevant for many application domains. ECHT'92 will be of interest to a broad spectrum of professionals ranging from theoreticians to system and application developers, from researchers to authors and end-users.

The conference will include prominent guest speakers, presentations of refereed papers, panel sessions, technical briefing sessions, poster and video presentations, as well as demonstrations of experimental research prototypes and commercial products. The conference will also feature two days of introductory and advanced tutorials on a variety of topics. There will be opportunities for informal meetings of special interest groups.


You are invited to participate in ECHT'92 and to submit original papers, proposals for panels, tutorials, technical briefings, demonstrations, videos, and poster sessions. All submissions will be stringently reviewed to ensure the highest levels of originality and merit. We encourage innovative submissions in any area concerned with Hypertext and Hypermedia research development and practice .

A non exhaustive list of suggested topics includes:

Hypertext and Hypermedia:

Courses enhance the skills and broaden the perspective of their attendees. Courses should be designed to provide advanced technical training in an area, or to introduce a rigorous framework for learning a new area. Courses can be proposed for half-day (3 hours) or full-day (6 hours) length. Courses that focus narrowly on a particular product or research agenda, are not appropriate. A non exhaustive list of appealing areas is: hypertext in education; hypertext for cultural applications; technical hyperdocumentation; hypertext system implementation; multimedia technology; evaluation and criticism; methodologies and approaches to hypertext authoring; interface design; film, video, and visual rhetorics; artificial reality. Courses will be selected on the basis of the instructors' qualification for teaching the proposed course and the contribution to the overall conference program.

Submission: proposals should describe the content of the course and its format (1000-2000 words), should identify the target audience, the level of expertise required, and the length

(1 or 2 half days). Qualification and profile of the instructor(s) should also be included. A separate page containing title, name(s), affiliation(s) and complete mailing address(es) (incl. phone, telefax, e-mail) of the instructor(s) must be provided.

Panels are meant to provide an interactive forum for involving both panelists and audience in lively discussions and exchanges of different points of view. Panels for ECHT '92 will not take the almost "traditional" format of symposia or mini paper sessions in disguise. Instead ECHT'92 panels will focus on lively discussions by panelists who bring different perspectives to an important and controversial topic. Panelists should not present lengthy position statements. Panels should be moderated by someone who is comfortable interviewing panel members, interrupting panelists at appropriate times, keeping the discussion on track and being able to weave together the thoughts of the panel members. The panel should address fundamental issues,questions and approaches which are of current interest focusing on specific topics rather than dealing with broad and general areas.

Submissions: moderators are invited to provide a description of the proposed panel by submitting 3-5 pages listing the topic (e.g., by providing leading questions to be raised by the moderator), the specific format intended, the names and affiliations of the panelists with their specific backgrounds and their positions on the (hopefully controversial) issues of the panel. Panel statements will appear in the proceedings.

A separate cover page must contain the title of the panel, names, affiliations and complete mailing addresses (incl. phone, telefax, e-mail) of the panelists.

Demonstrations, posters, and videos

Demonstrations provide the attendees with the opportunity to experience hypertext systems and question the developers of the systems. Poster presentations give researchers the opportunity to present significant work in progress or late-breaking results and to discuss their work with those attendees most deeply interested in the topic. Videos are appropriate for illustrating concepts that are best captured visually.

Submissions: demonstrations and posters should be submitted in the form of an extended abstract (approx.1000 words), describing the content, the relevance for the conference and what is noteworthy about the presented work. Demonstrators are informed that they must provide their own hardware. Videos should be submitted in the form of a 5 to 10 minutes VHS, PAL or NTSC tape, with a 500 words abstract, describing the content, relevance and noteworthiness as above. A separate page must contain the title of the demo, poster or video, name(s), affiliation(s) and complete mailing address(es) (incl. phone, telefax, e-mail) of the author(s).

Technical Briefings

Technical briefings aim at providing a presentation medium for presenting details of a concrete design rather than an empirical or theoretical contribution. Presentations should emphasize experience in the design and implementation of hypertext systems or applications, and discuss decision points and trade-offs. Briefings are intended to deliver valuable technical messages to the audience. Briefings are encouraged to be accompanied by a live interaction with the system.

Submissions: Proposals (approx. 1500 words) should be submitted in five paper copies and outline the points to be made in the briefing. A separate page must contain the title of the briefing. name(s), affiliation(s) and complete mailing address(es) (incl. phone, telefax, e-mail) of the author(s).

Milan: beyond industry

For many people, Milan, the economic capital of Italy, is represented by its industriousness, its industries, and advanced services sector. It is usually considered a rather drab city with hardly an history that is totally concentrated on production.

As a matter of fact, the origins of Milan are extremely ancient. The city first developed under the Romans who named it Mediolanum (which means "the land in the middle") because its ideal geographical position made it an important hub for trade.

The vestiges of this period can still be seen throughout the city center. During the Medieval Era Milan was a free municipality. Later on it became a part of the seigniory of Visconti and Sforza dynasties, and subsequently fell under Spanish and Austrian rule.

The city urban layout continued to systematically expand in successive concentric circles. Different customs, the arts, and culture flourished in each of these periods.

The Cathedral, "il Duomo", for years considered the tallest building in Italy, was built between the 13th and 15th centuries. The "Navigli" - artificial waterways- which permitted trade as well as the transportation of large blocks of marble for the construction of the Cathedral were also built during that period.

Many artists lived in Milan when the city was a part of the Sforza seigniory. Leonardo da Vinci sojourned in Milan various times between 1482 and 1513. Here he created masterpieces such as the frescoes in the hall of the Rafters in the Sforza Castle and the "Last supper" fresco in the Santa Maria delle Grazie Convent.

Although the period under Spanish rule (1535-1706) was marked by the plague and a decrease in population, the years under Austrian rule on the contrary, were characterized by flourishing cultural and economic activities.

The La Scala Theatre, which the sovereign had called the "Most beautiful theater in the world", was also created in this period. Designed by Piermarini and inaugurated in 1778, La Scala immediately became the point of encounter between high society and culture, and decreed the success of operas by Bellini, Donizetti and Verdi.

Therefore, Milan, a city where culture, art, reformist ideals and industriousness have always been indissolubly linked, is considered by many as the second capital of Italy.

Today the connection between entrepreneurial activities and creativity has made Milan the capital of fashion, design, publishing, and advertising. Almost all of the most famous designers and advertising executives live and work in Milan.

Milan is also host to the Modit and Milanovendemoda exhibitions, events that have established Italian ready-to-wear fashion in the world; the Furniture Show, a biennial exhibit of the best Italian furniture production and design; and many other commercial and cultural events.

Moreover most of the publishing houses and the headquarters of fashion and design magazines are located in Milan.

However those persons who are not a part of the creative world can always find an interesting exhibit or trade fair to visit in Milan such as SMAU, one of the most important exhibitions of innovations in information technology, telecommunications, and office furniture.

Having cast off the drab mantle of the industrial city, for some years now in Milan has been pointing towards the advanced services sector and the post-industrial era.

The shopping opportunities are extremely vast, from the most sophisticated boutiques to skillfully made artisan objects, from shopping centers to specialized stores.

Milan's excellent connections with the most important tourist spots in Italy should also be emphasized: one can reach the picturesque lakes area in about an hour or take a short trip to go skiing on the Alps or swimming in the sea near Portofino. Venice, Florence, and Rome can be easily reached by fast trains: the "Pendolino", the new super fast commuter train, arrives in Rome in just three hours and 50 minutes.

Surrounded by sea, mountains, and lakes the city of Milan in equilibrium between past, present and future, has much to offer to the visitor wanting to discover it.
