Abstract The aim of the project is to develop a “Java Automatic Grader” for java project assignment. It ensures that every assignment or work given to the students is done in the right way. The student should get automatic evaluation after submitting the assignment. We are implementing each test case in such a way that student should only get marks for satisfying all the requirements of the project assignment in fruitful manner i.e. If the student submits the assignment by reaching all the requirements and the expected result is achieved in the right way, then only the student will get full marks.

Efficient RDF Storage and Retrieval in Jena2
Efficient RDF Storage and Retrieval in Jena2 Kevin Wilkinson1, Craig Sayers1, Harumi Kuno1, Dave Reynolds2 HP Laboratories 1 1501 Page Mill Road Palo Alto, CA, 94304 USA 2 Filton Road, Stoke Gifford Bristol BS34 8QZ United Kingdom [email protected] Abstract. RDF and related Semantic Web technologies have been the recent focus of much research activity. This work has led to new specifications for RDF and OWL. However, efficient implementations of these standards are needed to realize the vision of a world-wide semantic Web. In particular, implementations that scale to large, enterprise-class data sets are required. Jena2 is the second generation of Jena, a leading semantic web programmers’ toolkit. This paper describes the persistence subsystem of Jena2 which is intended to support large datasets. This paper describes its features, the changes from Jena1, relevant details of the implementation and performance tuning issues. Query optimization for RDF is identified as a promising area for future research. 1.0 Introduction Jena is a leading Semantic Web programmers’ toolkit[1]. It is an open-source project, implemented in Java, and available for download from SourceForge. Jena offers a simple abstraction of the RDF graph as its central internal interface. This is used uniformly for graph implementations, including in-memory, database-backed, and inferred graphs. Jena2 is the second generation of the Jena toolkit. It conforms to the revised RDF specification, has new capabilities and a new internal architecture. A design principle for Jena2 was to minimize changes to the API. This simplifies migration from Jena1 to Jena2. This paper describes Jena2 persistent storage; details on other aspects of Jena2 are available in [2].

Analizamos 19 Plataformas De E-Learning
Analizamos 19 plataformas de e-Learning En este libro, en el que se analizan 19 plataformas de e learning (también llamados sistemas de gestión de aprendizaje y entornos para la creación de aulas virtuales o de educación a distancia) se realizó en el marco de las iniciativas y proyectos colaborativos surgidos en el Congreso Virtual Mundial de eLearning, entre ellas: el Primer MOOC de habla hispana y GEIPITE (Grupo de Estudio abierto y colaborativo en Investigación y Prácticas sobre la Influencia de las TIC en la Educación). Es por eso que este monográfico se convierte en la primera investigación académica colaborativa (por lo menos de habla hispana y en América Latina, pero posiblemente a nivel mundial) realizada íntegramente de forma sincrónica y conjunta (excepto la edición y el formato final para la Editorial) con herramientas de escritura en tiempo real. Su elaboración incluye tanto la investigación teórica como el trabajo de campo, con todo lo que ello implica: seguramente hayan muchos errores, procesos y elementos a mejorar en futuras ediciones, pero es sin duda otro precedente que hace nuevamente precursor a Investigación colaborativa sobre LMS nivel global al Congreso Virtual Mundial de eLearning.

Així doncs, l’objectiu del desenvolupament pràctic és permetre que aquesta pugui ser nodrida a partir de diversos repositoris de dades i, per tant, unificar la terminologia de l’estructura d’aquestes fonts amb la finalitat que l’ontologia pugui ser utilitzada per programaris externs que cerquin generar coneixement i proporcionar suport a l’hora de prendre decisions.
