THE OFFICIALS CRIMES OBJECTS STRUCTURING

Describing, Structuring and Implementing Objects

The popularity of the notion of object for structuring (the specification of) systems has not been accompanied by the necessary formalisation of the concepts and constructions involved. We have a well developed theory of abstract data types that explains how to structure specifications based on the notion of value, but objects involve imperative notions such as those of action and state which a...

Structuring a Compiler with Active Objects

We present a concurrent compiler for Active Oberon built itself with active objects. We describe the experience made on parallelizing the Oberon compiler, in particular explaining how concurrency and synchronization are achieved by using active objects, and showing how we achieved ensured deadlock freedom. Based on the implementation, we discuss why we consider active objects beneficial for the...

Using Objects for Structuring Multiparadigm Programming Environments

Multiparadigm programming allows the programmer to write the implementation of a system in a number of different paradigms. We describe our approach to multiparadigm programming based on modeling programming paradigms as object classes. In particular, objects can be used to encapsulate program modules, and classes to encapsulate their respective paradigms. The paradigm class hierarchy can then ...

Hierarchical Structuring of Cultural Heritage Objects within Large Aggregations

Huge amounts of cultural content have been digitised and are available through digital libraries and aggregators like Europeana.eu. However, it is not easy for a user to have an overall picture of what is available nor to find related objects. We propose a method for hierarchically structuring cultural objects at different similarity levels. We describe a fast, scalable clustering algorithm wit...
