Weighted Spanning Tree Constraint with Explanations

Minimum Spanning Trees (MSTs) are ubiquitous in optimization problems in networks. Even though fast algorithms exist to solve the MST problem, real world applications are usually subject to constraints that do not let us apply such methods directly. In these cases we confront a version of the MST called the “Weighted Spanning Tree” (WST) in which we look for a spanning tree in a graph that sati...

In research areas such as decision support systems, one of the crucial features is the ability to automatically explain decisions. However, this ability does not typically play a large role in computer games. Here, I suggest that this situation will change: research on the automatic generation of explanations will have real import for many types of computer games. I discuss four possible ways t...

Generating Process Explanations in Nuclear Astrophysics Generating Explanations in Astrophysics

In this paper we describe ASTRA, a computational aid for generating process explanations in nuclear astrophysics. The system operates in two stages, the rst using knowledge of quantum theory to produce a set of legal reactions among elements and the second searching for pathways of such reactions that explain the evolution of some element in terms of lighter ones. ASTRA has found apparently nov...

Great Explanations: Opinionated Explanations for Recommendation

Explaining recommendations helps users to make better, more satisfying decisions. We describe a novel approach to explanation for recommender systems, one that drives the recommendation process, while at the same time providing the user with useful insights into the reason why items have been chosen and the trade-offs they may need to consider when making their choice. We describe this approach...
