The goal of the research described in this paper is to develop an application-independent presentation tool that automatically designs effective graphical presentations (such as bar charts, scatter plots, and connected graphs) of relational information. Two problems are raised by this goal

-scale data analysis problems. We also present examples of graphical models in bioinformatics, error-control coding and language processing.

An automatic presentation system is an intelligent interface component which receives information from a user or application program and designs a combination of graphics and text that effectively conveys it. It is a facility that assumes the presentation responsibilities for other programs

this paper consist of directed graphs containing nodes, denoted by K; L; M , and wires connecting the nodes. For the moment, a node K looks like K k l where the number of wires going in and out of K depends on the specification of K given by a signature. The signature K = (P; K) consists of a set P of basic types, called prime arities and denoted by p; q; r; : : : , and a set

In our era of "shareholder value", news of redundancies in leading global companies is good news for the stock market. The coincidence of this kind of news with growing unemployment creates the impression of a direct and simple relationship between the two developments. In this paper, we use official data on employment and unemployment and exploit a number of surveys of establishments, individuals and, more specifically, unemployed persons in order to point out several paradoxes. We find that dismissals for economic reasons account for only a fairly small share of separations. Furthermore, the contracting sectors produce less job destruction, have less labour turnover, make less use of dismissals and produce below-average unemployment inflows. We find also that among samples of unemployed persons the percentage of those who lost their last job due to a dismissal for economic reasons is rather high. We do not know, however, from which sectors these unemployed originated. From an analytical perspective, it must be concluded that the mechanisms by which structural change produces unemployment are still rather obscure. Event history analysis based on data sets of individuals is needed to shed more light on

The mechanism for curriculum revision and realization

BOZ is an automated graphic design and presentation tool that designs graphics based on an analysis of the task for which a graphic is intended to support. When designing a graphic, BOZ aims to optimize two ways in which graphics help expedite human performance of information-processing tasks: (1

information visualization, information physics. We describe the current status of Pad++, a zooming graphical interface that we are exploring as an alternative to tradhional window and icon-based approaches to interface design. We discuss the motivation for Pad++, describe the implementation

A new method for nonparametric multiple regression is presented. The procedure models the regression surface as a sum of general- smooth functions of linear combinations of the predictor variables in an iterative manner. It is more general than standard stepwise and stagewise regression procedures
