Tidskriftsartikel (refereegranskat)abstract
- The OtaOnline project at the Helsinki University of Technology has been deploying the distribution of Finnish newspapers such as Iltalehti, Aamulehti and Kauppalehti on the Internet since 1994, The editors produce the electronic counterpart of these papers by a conversion process from QuarkXpress documents to HyperText Markup Language. The project is about to step into a new phase by introducing an approach which provides many new features not available in the old process. This paper describes an object-oriented approach which implements the logical model of a hypermedia newspaper. This model encapsulates the structure of the hypermedia documents as well as their capability for transforming into different presentation formats. It also provides a semantical rating mechanism to be used with intelligent agents. A distribution scheme which enables efficient use of this model is also presented

Requirements for an Electronic Newspaper
- 1996
-
Konferensbidrag (refereegranskat)abstract
- The OtaOnline project at the Helsinki University of Technology has been deploying the distribution of ordinary newspapers on the Internet since 1994. So far the electronic counterpart has been produced through a series of conversions. Now a more controlled approach needs to be defined in order to bring added value to the electronic version. This paper describes requirements for a system implementing a product concept of an electronic newspaper which allows for more flexible generation, distribution and processing of the documents. We aim at multi-purpose publishing by supporting several presentation environments and distribution channels. Personalisation aspects are also discussed from the contents point of view. Concrete suggestions for implementing the features are given and implications of this approach are also presented. 1 Introduction The OtaOnline-project is a testbed at the Helsinki University of Technology campus. It has provided the students and staff with an electronic

Architecture for Agent-mediated Personalised News Services
- 1996
-
Konferensbidrag (refereegranskat)abstract
- Emerging agent technology can be used to implement a personalised news service. The consumer agent has a model of user's preferences and is able to request information that fulfills these needs. The producer agent has a logical model of the contents of the multimedia objects that are available for service. On the basis of this model, the producer agent can advertise its services in the network to potential consumer agents. The selected multimedia items are offered to the consumer as a personalised newspaper. This architecture is used in practise in building a personalised newspaper for the World Wide Web, which selects and presents the user with articles that match user's preferences. The article selection process is a combination of keyword searches, semantic matching and social filtering. In our agent-based service, the newspaper editors have an important role in defining semantic categories for the contents of the service, and in providing necessary metadata about the news articles....
