Linguistic Tree Constructor
Syntax tree editor for rapid annotation of existing text
Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format. -

Datalog Educational System
Deductive Database with Datalog, SQL, RA, TRC, DRC
The Datalog Educational System (DES) is a deductive database with Datalog, SQL, Relational Algebra, Tuple Relational Calculus and Domain Relational Calculus as query languages developed mainly for education. It can be used from most common Prolog interpreters over any supported OS and from portable executables (Windows, Linux and MacOS). -

Programming Language ADP
ADP is a script language designed for Web database prgramming.
ADP (Another Data Processor) is a programing language that is designed for Web database programing. It is a scripting language and a lightweight programming language in which it is possible to mix SQL easily. It is easy to install. ADP is base on Prolog. But ADP uses only the backtrack and unification. The syntax is original and likes a another scripting language, supports method call. -

ConceptBase.cc
A Database System for Metamodeling and Method Engineering
ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license. -

Teaching Planner
Teaching planner tool to help universities in developing countries
This project objective is realizing the design, development and implementation of a web application which works as a university planner. The objective was that the system could be installed specifically in the user university and run through the web browser as a local page or having the possibility of installing it in a university server (could be in any site, no need to be in the user university) so through the browser and an internet connection it could be used from anywhere (mainly in developing countries which is the target of the project). The project was initially thought for the Ngozi university in Burundi, so it tries to fulfill the requirements from that university, but the design is as open as it could be so it can be adapted to work on other universities. -

s(ASP)
Implements the stable model semantics without grounding.
s(ASP) is an implementation of the stable model semantics of logic programming. Unlike similar systems, it does not employ any form of grounding. This allows s(ASP) to execute programs that are not finitely groundable, including those which make use of lists and terms. Work on s(ASP) is supported by the National Science Foundation under Grant No. 1423419. Details of how s(ASP) works can be found in the following paper: Marple, Kyle, Elmer Salazar, and Gopal Gupta. "Computing Stable Models of Normal Logic Programs Without Grounding." arXiv preprint arXiv:1709.00501 (2017) (https://arxiv.org/abs/1709.00501). -
