Galliwasp: Goal-directed Answer Set Solver. With Marple, Min, Bansal.
CoLP Metainterpreter: Meta-interpreter for co-LP. With Kluzniak, Simon, Mallya, Bansal.
NEXUS parser: A parser for NEXUS (NEXUS is a bioinformatics
mark-up language).
ExSched System: An Excel Plug-in for Knowledgesheet (see below).
A spreadsheet interface for solving constraint satisfaction
problems. With Tiwari, Chitnis, Yennamani. 2006. Used in the past by CS
and EE departments to automatically schedule courses.
VoxBoox System: A system for automatically generating interactive
talking books. With Aanchal Jain Click here to see demo.
DAWN System: A system that allows interactive audio/voice
based aural surfing of the WWW over the phone. With Raman, Nichols, Reddy, Annamalai.
Semantic Web System: Semantically maps RDF documents and
RDQL queries to Horn logic. The RDQL queries can then be
executed w.r.t. RDF data. With Kunal Patel, 2003.
TA Scheduler: Automatically assigns to TAs to courses.
Used at UTD since fall 2002 to make assignment for 70+ TAs to
about 120 courses. With
King, Gupta, Guballa, Mallya. 2003.
HTML to VoiceXML Transcoder: converts any HTML 4.0 web-page
to VoiceXML. Extensible. Developed
in Java (initial prototype in Prolog). With Narayan, Gupta, Dr. Prabhakaran.
Transform: Bioinformatics
interoperability tool (available through
swbic.org). With Drs Pontelli,
Ranjan, Milligan. 2001.
PALS: Parallel ALS, a distributed logic programming system based
on the commercial ALS Prolog system. Implements full Prolog, and runs
on Beowulf (ca. 2002). Built on top of
Applied Logic System's (ALS) WAM, uses MPI and the novel
technique of stack-splitting to realize distributivity.
Villaverde, Pontelli, Gupta, Guo.
TALS: Tabled ALS, a tabled logic programming system based
on the commercial ALS Prolog system. Implemented on top of ALS WAM, uses
novel technique of dynamic reordering of alternatives.
With Hai-Feng Guo.
NADA: An automatic system for checking undergraduate graduation requirements and
providing advise automatically to students (built for NMSU).
Implemented using Prolog + Java. Jose-Mendez, Karshmer, and Gupta. 1999.
ACE: A High Performance Parallel Prolog System implemented
on top of SICStus Prolog. Runs on SMMs. Pontelli and Gupta.

of logic programs. Runs on daVinci. Vaupel, Pontelli, Gupta.
No longer maintained or available.
Knowledgesheet: A Spread-sheet based tool for solving
constraint satisfaction problems. Akhtar and Gupta.
Nemeth to Latex Backtranslator: A system for converting
Nemeth Math Braille document to Latex.
2001. Try the expression coverter here:
Nemeth Math to Latex Backtranslator (alpha).
