Personalized ranking with implicit feedback (e.g. purchases, views, check-ins) is an important paradigm in recommender systems. Such feedback sometimes comes with textual information (e.g. reviews, comments, tips), which could be a useful signal to reveal item properties, identify users’ tastes and interpret their behavior. Although incorporating such information is common in explicit feedback ...

In this paper we develop a method for zooming in complex information spaces consisting of geometric models and associated textual explanations. In particular we introduce a technique to extend fisheye views to the exploration of three-dimensional models. The result of a zooming process is a modified geometric model which is rendered and presented to the user with appropriately selected and well...

UQ? is an evolving generic language-based environment for manipulation of structured documents. The environment is intended to capture both syntactic and relational structure within and between documents and to support user interaction via both textual and diagrammatic views. This paper illustrates the innovative features of the environment description language used to instantiate a UQ? environ...

With regard to the relationship between the use of modality and readability levels oftexts, 2 opposing views have been raised. The first view endorses direct positiverelationship between modality and readability in the sense that the use of modalityincreases textual understandability. The second view is that the use of modality leadsto an increase in the number of words, resulting in readabilit...

This paper presents Composer, an authoring tool to help creating interactive TV programs for the Brazilian Terrestrial Digital TV System. In Composer, several abstractions are defined creating different document views (structural, temporal, layout and textual). One of these views, the temporal view, preserves as much as possible the timeline paradigm, so popular in TV program editing. Using thi...

SPE is an environment for developing object-oriented software. It allows a programmer to construct multiple visual and textual views of a program, each of which can be edited. All views are kept consistent through an underlying change propagation mechanism. Using this mechanism, together with tools which permit simple flow between phases, SPE encourages an evolutionary approach to object-orient...

We evaluate a new visual programming system PrologSpace. The system addresses classic issues of visual interfaces: layout, shape, colour, and iconography; and those of particular concern to visual programming: multiple views (visual abstractions), synchronised views, integration of visual and textual dimensions, visual debugging, cognitive dimensions, and the problems of scale. We describe the ...

In many applications there is a need to keep shared or related information consistent. For example, in a CADrafting package it is necessary to keep views of an artefact from different perspectives consistent with one another. In software development environments there is a need to keep diagrammatic views, such as OO analysis diagrams, consistent with corresponding textual code. In this paper, w...

A new approach to building Integrated Software Development Environments (ISDEs) is described. Graphbased representations of software system data, and multiple views of this data, are kept consistent by having graph components respond to descriptions of changes made to related graph components. This technique supports integrated, bi-directionally consistent graphical (interactively-edited) and t...
