X5gon: Cross Modal, Cross Cultural, Cross Lingual, Cross Domain, and Cross Site Global OER Network

Periodic Reporting for period 2 - X5gon (X5gon: Cross Modal, Cross Cultural, Cross Lingual, Cross Domain, and Cross Site Global OER Network)

Reporting period: 2018-09-01 to 2020-12-31

The proposal X5gon stands for easily implemented freely available innovative technology elements converging currently scattered Open Educational Resources (OER) available in various modalities across Europe and the globe. X5gon combines content understanding, user modelling, quality assurance methods and tools to boost a homogenous network of (OER) sites and provides users (teachers, learners) with a common learning experience. X5gon deploys open technologies for recommendation, learning analytics and learning personalisation services that works across
various OER sites, independent of languages, modalities, scientific domains, and socio-cultural contexts. It develops services OER media convergence including full courses, course materials, modules, textbooks, videos, tests, software, related events, tools, materials, techniques used to support access to knowledge. Fivefold solutions are offered to OER sites:
• Cross-modal: technologies for multimodal content understanding;
• Cross-site: technologies to transparently accompany and analyse users across sites;
• Cross-domain: technologies for cross domain content analytics;
• Cross-language: technologies for cross lingual content recommendation;
• Cross-cultural: technologies for cross cultural learning personalisation.
X5gon collects and index OER resources, track data of users’ progress and feed an analytics engine driven by state-of-the-art machine learning, improve recommendations via user understanding and match with knowledge resources of all types.
The project has created a number of services and has run a series of pilot case studies that enable the measurement of the broader goals of delivering a useful and enjoyable educational experience to learners in different domains, at different levels and from different cultures.
The project has developed a commoditised set of tools and systems that enable the ingestion of OER material into the X5gon registry including semantic cross-lingual indexing of materials, automatic transcription and translation of recordings, assessment of how engaging the material is, and potentially how it might sequence with other OERs. Further, methods for automatically estimating the knowledge of users based on their track record of viewing different OERs enables the system to recommend content that is likely to engage and prove useful for learners and teachers. For example, a moodle plug-in can provide such recommendations at the level of a particular course, while the X5learn system can make recommendations to individual learners based on their earlier viewing experience. The project has actively engaged with OER sites and developed systems to assist with the incorporation of OERs into the X5gon registry significantly growing the number of sites and materials that are indexed by the X5gon tools.

The project has been actively supporting the use and promotion of OERs though a network of contacts and events. It has promoted the adoption of the UNESCO recommendation on the use of OER in November 2019 and has supported the coalition that is pushing for greater standardisation and roll-out of OERs world-wide.

The project has made a number of advances in the state-of-the-art in the different domains that contribute to the overall objectives of the project, including ASR (automatic speech recognition), automatic machine translation, semantic indexing of OERs, automatic modelling of user knowledge, novel user interfaces to facilitate access to video lectures and other OERs, and automatic sequencing of OERs to facilitate ease of learning. The systems created have the potential for a variety of impacts. These include
• the provision of a learning portal that can be promoted internationally through UNESCO and AI4EU among other channels, realising the potential for on-line learning globally;
• the development of bespoke solutions for businesses wanting to improve access to educational and informational materials within their organisations;
• adaptations of educational portals to enable easier access for individuals with different accessibility requirements.
