AlterEgo E-Mail Filtering Agent - Using CBR as a Service
Michael Redmond, Beth Adelson · 1998
With the growth and commercialization of the Inter-net, many busy people find themselves receiving more e-mail than ever before. Thus, e-mail filtering has be-come an important problem. Many mailers provide filtering based on the mail header: the sender, the do-main of the sender, and the subject. In the first phase of the AlterEgo project, we are developing an e-mail filtering agent that uses the content of the whole mes-sage, plus a model of the world and a model of the user, including their important goals. Initially, Case-Based Reasoning seemed llke a promising master approach; messages that are similar to messages that were deemed important in the past should be important now. How-ever, since the user’s world may often change signifi-cantly and sometimes uddenly, the relevant similarity to a past message may be at a very abstract level. This will result in an expensive search for similarity. Hence, in our initial prototype, we have developed an approach that is driven by model-based reasoning, and is aided by case-based reasoning.
