The contribution of this article is to bring the interesting features SPARQL conceptual graph model while preserving its distinctive and especially graphical ones.Therefore presents a general query language, called CGQL.This also provides an experimental comparison between CGQL engines: it shows interest our implementation for querying knowledge.

Natural language (NL) interfaces for DB query formulation have always been recognized as a much needed enhancement for end-users. Poor performances with earlier NL systems had led to a lull in research in this field. However, latter-day experiments and systems appear to be sufficiently more promising to warrant continued and further research in this area. This study proposes an experimental que...

DNA computing has a rich history of paradigms with great expressive power. However, far less power is needed for data manipulation. Indeed, the relational algebra, yardstick database systems, expressible in first-order logic, and thus powerful than Turing-complete models. models have to account many varied scenarios. A implementation manipulations might be nimbler perform its operation faster m...
