The DIG Interface provides an implementation-neutral mechanism for accessing Description Logic reasoner functionality. At a high level the interface consists of XML messages sent to the reasoner over HTTP connections, with the reasoner responding as appropriate. Key changes in the current version (DIG 2.0) include support for OWL 1.1 and well-defined mechanisms for extensions to the basic inter...

IS_SUM is a summarizer developed at Institute of Software (IS) of Chinese Academy of Sciences for DUC 2005. We adopt a new way for clustering and summarizing documents by integrating Document Index Graphic (DIG) [7] with Lexical Chains [5]. Our results show the benefit of integrating DIG with Lexical Chains.

The DIG Interface provides an implementationneutral mechanism for accessing Description Logic reasoner functionality. At a high level the interface consists of XML messages sent to the reasoner over HTTP connections, with the reasoner responding as appropriate. This paper reports on enhancements of the DIG interface, including support for new language constructs and an extension mechanism.

Intramolecular cyclization of nitrogen-tethered alkynyl esters catalyzed by phosphazene organosuperbases P2-tBu and P4-tBu was investigated. Both acyclic and cyclic substrates underwent 5-exo-dig and 5-endo-dig cyclization. This reaction is a rare example of the intramolecular addition of enolates of simple esters to alkynes.

Titanium-catalyzed hydroamination of 1,4- and 1,5-diynes by primary amines leads to imino-alkynes that undergo in situ 5-endo dig and 5-exo dig cyclization reactions, respectively. The products are 1,2,5-trisubsituted pyrroles accessed directly from readily available diyne starting materials.

This paper describes Dig-Force2, a system that securely logs and stores evidentiary data about the operation of a personal computer. The integrity of the logged data is guaranteed by using chained hysteresis signatures and a trusted platform module (TPM) that prevents unauthorized programs or tampered programs from executing. Experiments indicate that the Dig-Force2 system is both efficient and...
