The Wizard of Oz (WOz) technique is an experimental evaluation mechanism. It allows the observation of a user operating an apparently fully functioning system whose missing servic...
Functional language compilers implement only weak-head reduction. However, there are cases where head normal forms or full normal forms are needed. Here, we study how to use cps c...
We present an approach to modeling the average case behavior of learning algorithms. Our motivation is to predict the expected accuracy of learning algorithms as a function of the...
Program refactoring, feature-based and aspect-oriented software synthesis, and model-driven development are disjoint research areas. However, they are all architectural metaprogram...
We report on the birth and evolution of Lua and discuss how it moved from a simple configuration language to a versatile, widely used language that supports extensible semantics, ...
