A comparison between Alice and Elizabeth chatbot systems
BA Abu Shawar, Eric Atwell · White Rose Research Online (University of Leeds, The University of Sheffield, University of York) · 2002
This study examines two chatter bots systems called ALICE and Elizabeth, which are adapted from ELIZA program. Joseph Weizenbaum implemented ELIZA in 1966 and it was originally designed to emulate a psychotherapist. This report also provides an introduction to the analysis of ALICE and Elizabeth focusing in the knowledge representation and pattern matching algorithms for each one of them. The report then illustrates the main differences between them and concludes that it will be easier to build machine learning for ALICE because of its simple pattern matching techniques than building one for Elizabeth since it depends on rules.
