摘要

Online technologies enable a host of observable acts, such as wishlisting, that do not quite amount to choice meant as a final selection. Rather, they express interest and a positive attitude towards an item. We gather this type of behaviour under the term approval . With items presented as a list, we propose a model of approval. We completely characterise the model in terms of simple properties of observed approval data. We introduce and study the problem of list design . This captures situations where an interested party can manipulate the approver's behaviour by choosing the list with the aim of maximising an objective.
