U-Talent brengt docenten informatica uit de regio bij elkaar in het Docentennetwerk informatica. Op een informele manier presenteren we ontwikkelingen in het vakgebied en bespreken dit met elkaar. Het netwerk is bedoeld als “regionale vaksectie”, omdat op de meeste scholen slechts één informaticadocent lesgeeft.
De bijeenkomsten staan onder leiding van Christian Köppe (vakddocent informatica U-Talent en vakdidacticus informatica UU).
Programma
Deze bijeenkomst bestaat uit twee onderdelen. In een deel gaan deelnemers voorbeelden van (activerende) werkvormen rondom meer theoretische en/of abstracte concepten uit het examenprogramma delen. Yannis Velegrakis van de Universiteit Utrecht geeft in het andere deel een lezing over recent onderzoek rondom very large data (in het Engels, meer info zie beneden). Er is voldoende ruimte voor discussie in hoeverre dit onderzoek ook in het voortgezet onderwijs een rol zou kunnen spelen.
Title Seminar: Entity Linkage for heterogeneous environments
Abstract:
Data of interest is nowadays found distributed across different sources that have been developed at different times, for different purposes and with different requirements in mind. As such, the sources are naturally highly heterogeneous. To make the best out of this data, the different contents need to be integrated. When this is done, It may happen that for the same real world entity there are different structures modelling it, originating from the disparate sources. The situation may occur even within the same data sources since people enter data in different forms, or real world entities naturally evolve.
To have a coherent representation, these structures that model the same real world object need to be identified and merged into one single structure. This is known as entity linkage, entity identification, or entity matching and is a fundamental first step of every integration task. In this seminar we will talk and get familiar with the different kinds of heterogeneities that exist and the methods that can be used to perform entity linkage.
