Different presentations of candidate expansion terms have not been f ,~lly explored in interactive query expansion (IQE). Most existing systems that offer an IQE facility use a list form of presentation. This paper examines an hierarchical presentation of the expansion terms which are automatically generated from a set of retrieved documents, organisad in a general to apecific manner, and visualised by cascade menus. To evaluate the effactiveness of the presentation, a user test was carried out
more » ... to compare the hierarchical form with the conventional list form. This shows that users of the hierarchy can complete the expansion task in less time and with fewer terms over those using the lists. Relations between initial query terms and selected expansion terms were also investigated.
