Abstract. This paper presents SearchSleuth, a program developed to experiment with a form of automatic local analysis that extends the standard Web search interface to include a conceptual neighbourhood focused on a formal concept derived from the query. The conceptual neighbourhood is displayed with upper neighbours representative of a generalisation operation, and lower neighbours representative of a specialisation operation. SearchSleuth also introduces a notion of a categorisation operation, where the conceptual focus can shift to a sibling concept of the search concept.
