Hierarchical tree substructure search

The Hierarchical Tree Substructure Search (HTSS) system [25-27] generates a single rooted decision tree from database structures by gradually refining classification of... [Pg.493]

A rather different approach to substructure searching is used by at least two systems. One of these is the Chemical Information System (CIS) developed by Richard Feldmann and his colleagues at the National Cancer Institute, and its various off-shoots which include the Chemical Databank System (CDS) at the SERC Laboratory in Daresbury. The other is the Hierarchic Tree Substructure Search (HTSS) developed in Hungary. ... [Pg.120]
