The expected metric principle for probabilistic information retrieval
… some window of the top. For that goal, the Probability Ranking Principle, which ranks documents in decreasing order of probability of relevance, is provably optimal. However, there are many scenarios in which that ranking does not optimize for the user's information need. One example is when …

Information retrieval as card playing: a formal model for optimizing interactive retrieval interface
… interface card model can not only cover the Probability Ranking Principle for Interactive Information Retrieval as a special case by making multiple simplification assumptions, but also be used to derive a novel formal interface model for adaptively optimizing navigational interfaces in a …

Probabilistic information retrieval in a distributed heterogeneous environment
… documents. The model determines a procedure for ranking the documents that stems from the Probability Ranking Principle: For each subcollection the subcollection´s elements are ranked; the resulting ranked lists are combined into a final ranked list of documents where the ordering is determined …

A formal framework for optimizing and evaluating interactive retrieval system
… Card Model can not only cover the classic Probability Ranking Principle as a special case by making multiple simplification assumptions, but also be used to derive a novel formal interface model for adaptively optimizing navigational interfaces in a retrieval system. Second, we propose a …

Principles of usable query interfaces
… information, our next contribution is a principled way to take this structure into account when answering keyword queries. Because the same information can be represented in many ways, we propose the principle of {\it design independence}, which postulates that search results should not …
