Closure Properties of General Grammars – Formally Verified

Authors: Martin Dvorak and Jasmin Blanchette

Published in: LIPIcs, Volume 268, 14th International Conference on Interactive Theorem Proving (ITP 2023)

Abstract
We formalized general (i.e., type-0) grammars using the Lean 3 proof assistant. We defined basic notions of rewrite rules and of words derived by a grammar, and used grammars to show closure of the class of type-0 languages under four operations: union, reversal, concatenation, and the Kleene star. The literature mostly focuses on Turing machine arguments, which are possibly more difficult to formalize. For the Kleene star, we could not follow the literature and came up with our own grammar-based construction.

End-user Programming of Ambient Narratives

Authors: Mark van Doorn

Published in: Dagstuhl Seminar Proceedings, Volume 7081, End-User Software Engineering (2007)

Abstract
Ambient Intelligence is a vision on the future of consumer electronics, telecommunications and computing in which devices move into the background while at the same time placing the user experience in the foreground. Producing Ambient Intelligent environments on a large scale is problematic however. First, it is technologically not possible in the foreseeable future to mass produce a product or service that generates Ambient Intelligence, given the current state-of-the-art in machine learning and artificial intelligence. Second, it is economically not feasible to manually design and produce Ambient Intelligence applications for each person individually. One of the main research questions in creating such environments is the design of a system capable of supporting mass customization of ambient experiences by means of end-user programming. A brief outline of the approach taken to address this question is described including future research.
