Document retrieval based on string searches typically returns either the whole
document or just the occurrences of the searched words. What the user often is after,
however, is microdocument: a part of the document that contains the occurrences
and is reasonably self­contained.
These microdocuments might, for instance, consist of several successive text para­
graphs sharing a mutual subject. Single paragraphs, or corresponding close­to­leaf
Sgml elements, do not convey enough of the contextual information. On the other
hand, sections or subsections of a text document, such as a book or an article, can
discuss many heterogeneous topics, and thus be too large a unit for retrieval or
We claim that such microdocuments are both suitable retrievable units and ap­
propriate units for document assembly, and that they can be reasonably well located
