Abstract

An interactive interface for creating a search query for a corpus of machine-readable documents, each of which is associated with at least one category of a category hierarchy. The interactive interface includes a cone tree generation component, a query specification component, a begin search component, and a query generation component. The cone tree generation component generates and displays a cone tree representing the category hierarchy. The cone tree represents each category of the category hierarchy as a node having a selection object for indicating inclusion of the category in a one of a first group, and a second group. Each selection object is responsive to a cursor control device. The query specification component generates and displays a query specification object including a first group object and a second group object. Each group object is responsive to the cursor control device and indicates members of the group. Each group includes a one of a term included within the corpus and a category of the category cone tree. The begin search component generates and displays a begin search object responsive to the cursor control device. The query generation component generates a query for searching the corpus to find documents that include at least one member of the first group and at least member of the second group.
