Abstract
Considers 'about' as it is used in an information retrieval sense, e.g. when an indexer judges that a document is or is not about a given subject. An operational definition of 'about' is given in which it is interpreted in terms of search behaviour. Concludes that 'about' is not the central concept in document retrieval theory. A document retrieval system should provide a search output in which documents are ranked according to the probability that they will satisfy the user's information need rather that according to the degree that they are 'about' the topic. 'Aboutness' is related to satisfaction probability
