Hepstructure is a new service for searching papers in SLAC SPIRES database. Its user can start without knowing what to put in the search request.

Among the features of this service are:

• Automated generation of hierarchical classification scheme for the papers. The scheme results from classification of the papers from the SPIRES database. The EqRank algorithm did the classification. The only input for the classification is the citation graph. The number of the levels in the hierarchy and the number of the clusters is determined by the algorithm. Generally, there is no external parameters (e.g., a preset list of clusters) in the algorithm. The algorithm creates the classification scheme, and indexes the papers by the created classification;
• A number of extra attributes for the elements of the classification (see Help);
• Accessability of the classification in responses to search requests via display options, e.g., display as Tree of Themes, and Refrerence (Citation) Tree;
• There are marks on the links (e.g., Hub, Authority, etc).
