Efficient multimedia search and retrieval with Elasticsearch by Sandy Ingram

Klewel, an SME based in Martigny, offers Triskel, an innovative and complete webcasting solution. Triskel consists of a cross-platform recording software communicating via an API with a multimedia processing application, and a Web portal for editing, sharing, and searching recorded content. This presentation will explain how Elasticsearch was used to efficiently search, within and across recorded presentations. Topics such as the structure of the indices, the modeling of search queries, and the type of data indexed will be discussed, followed by a demo.

Embedded Interactive Learning Dashboards With Elasticsearch and Kibana by Andrii Vozniuk

The React Group at EPFL conducts research and development in the field of interaction systems with particular focus on educational technology and learning analytics. Making sense of growing educational data requires deployment and usage of appropriate scalable, real-time processing tools supporting a flexible data schema, such as Elasticsearch. Until recently, the exploitation of Elasticsearch for learning analytics purposes by practitioners was hindered by a high entrance barrier due to the complexity of the query language and the query specificities. This is changing with the ongoing development of Kibana, an open-source tool that allows to conduct analysis, build visualisations of Elasticsearch data through a graphical user interface and combine those visualisations into dashboards. This feature is particularly important since learning dashboards are a popular mean of obtaining insight into the educational data by presenting an aggregated view of different learning indicators on a single display.
In this talk, I will first demonstrate how user-educational platform interactions can be captured by using the xAPI standard. Afterwards, we will build and play with a Kibana dashboard visualising these interactions in real-time. Finally, I will demonstrate how such a dashboard can be embedded into an existing web platform allowing its user to benefit from the provided analytics.
