Hypertext development should benefit from a systematic, structured development, especially in the case of large and complex applications. A structured approach to hypertext development suggests the notion of <italic>authoring-in-the-large</italic>. Authoring-in-the-large allows the description of overall classes of information elements and navigational(More)
In this paper we analyze the process of hypermedia applications design and implementation, focusing in particular on two critical aspects of these applications: the navigational and interface structure. We discuss the way in which we build the navigation and abstract interface models using the Object-Oriented Hypermedia Design Method (OOHDM); we show which(More)
This paper presents a search architecture that combines classical search techniques with spread activation techniques applied to a semantic model of a given domain. Given an ontology, weights are assigned to links based on certain properties of the ontology, so that they measure the strength of the relation. Spread activation techniques are used to find(More)
In this paper we discuss the use of design patterns for the process of building hypermedia applications. The idea of design patterns has been recently developed, and rapidly spread outside the object-oriented community to a general audience of software developers. By using patterns it is not only possible to document design experience with a very simple and(More)
In this paper we discuss the use of an object-oriented approach for web-based applications design, based on a method named Object Oriented Hypermedia Design Method (OOHDM). We first motivate our work discussing the problems encountered while designing large scale, dynamic web-based applications, which combine complex navigation patterns with sophisticated(More)
In this paper we present Web design frameworks as a conceptual approach to maximize reuse in Web applications. We first analyze the current state of the art of Web applications design, stating the need for an approach that clearly separates concerns (conceptual, navigational, interface). We briefly introduce the OOHDM approach for Web applications design.(More)
In this paper, we argue that web applications are a particular kind of hypermedia applications and show how to model their navigational structure. We motivate our paper discussing the most important problems in the design of complex Web applications. We argue that if we need to design applications combining hypermedia navigation with complex transactional(More)
