Introduction

Combining Linked Data and Mobiles Devices to improve access to OCW, IEEE EDUCON 2012

Most of the Web content is designed for human consumption and stored in a human-understandable but not machine-readable format.

Introduction


Consequently, the classical Web -a Web of Documents- is evolving toward a new and promising model called Semantic Web.

Introduction


Philosophy of GICAC (Group of Innovation in the Quality Management of Higher Education Institutions – UPM, Spain & UTPL, Equator):

Deploying Linked Open Data -particularly data of open educational materials- concerning universities, repositories, people, Open Educational Resources (OER) and Open Course Ware (OCW) from existing institutional repositories and databases, under OCW UNIVERSIA Consortium.

Mobiles and Education


New features of mobile devices promote creation of sites called Markets / Store

Applications designed for mobile devices can take advantage of other incorporated features (camera, microphone, GPS, WIFI, etc.)

Mobiles and Education


The influence of these devices in education has allowed the term "Mobile Education or Mobile Learning”

Context

Using Linked Data in the OCW Context

To improve discovery, accessibility, visibility and interoperability

Context


Using Linked Data in the OCW Context

Active role of Linked Data in the OCW context.

Current implementation of linked data in open educational contents as Linked OpenCourseWare Data Vocabulary (LOCWD)

Context


Context


LOCWD triplestore contains RDF data of OCW courses published by OCW-Universia network member countries sifting through a total of 1595 OCW courses. The data model is divided into subdomains• OCW repository properties• OCW properties• License properties• Link to datasets of interest in the LinkedOpenData cloud.

Architecture for LOCWD-Mobile


Proof-of-concept


Conclusions


Benefit of Combination of Linked Data and mobile devices

The mobile devices could produce OER's (with audio, video, photos, recommendations, etc.) and stored it in semantic repositories.

The users of mobile applications can improve User Experience by consuming semantically enriched information and linked data.
