Because Men Don’t Bite Dogs: A Logical Framework for Identifying and Explaining Unexpected News

Emma Byrne

The number of news reports published online is now so great that it is impossible for any person to read all of them. Not all of these reports are equally interesting. Automating the identifiication and evaluation of interest in news is therefore a potentially valuable goal. Traditional methods of informa- tion management such as information filtering, information retrieval and collaborative filtering are unsuited to the task of filtering news. This abstract presents a framework that permits the identi ication of interesting news by means of the identifiication of violated expectations. Facts derived from news reports, expectations and related background knowl- edge can be used to (i) justify the decision to rate news as interesting, (ii) explain why the information in the report is unexpected and, (iii) explain the context in which the report appears.
