Análisis de las tecnologías RDF, OWL, SWRL en la web semántica para crear ontologías de cursos virtuales a partir de base de datos de un LMS.

Abstract

The work aimed to study the architecture of the semantic web and the structure of the databases of a LMS Moodle, as well as analyze and determine the technologies of the Semantic Web that create ontologies and extract data from one LMS environment free. A software module that allows you to build an ontology from information database LMS Moodle and perform the validation of the extraction of data from LMS Moodle to ontology structured in a virtual environment of the Escuela Superior Politecnica de Chimborazo. For the development of the application that generates an ontology from the data of a course stored in a database Moodle, we worked with agile methodology XP that is oriented rapid application development, and interfaces that are developed are simple and intuitive for users. Following the analysis was obtained as a result that RDF and OWL technologies allow structuring ontologies more optimally extracting data from the database of a LMS Moodle, while technology SWRL also can be done, taking into account that it requires more resources. Therefore it was concluded that the technologies of the Semantic Web OWL and RDF, and the structure of the databases of a Moodle LMS in combination, can generate ontologies and extract data from a free LMS environment. As well as to develop a software module that allows you to build an ontology from information database LMS is possible, by using tools such as ARC and the php programming language. This module is relatively complex since its structure depends on the ontology built. And it is recommended that other alternatives must be analyzed from different libraries to ARC to work with PHP in the process of semantic web technology.
