It's All about Time: Towards the Real-Time Evaluation of Collaborative Activities

Abstract: In this paper, we propose a method for the real time evaluation of collaborative activities. The method aims to classify collaborative activities using a memory-based learning model and to evaluate them using a reference set of pre-evaluated activities. The proposed approach uses time series to represent activities and classifies them regarding their similarity. In order to evaluate the results, the method is used as an automatic rater of collaboration quality and the ratings are compared to ratings of human e… Show more

“…In this context, frequent occurrences of terms can contribute to raising the literary text level by adding new meanings and establishing new relations between entities. This type of data can be studied using statistical methods, one of which is chosen in this paper: analysis of discrete "events" in chats depending on the moment when they occur, enrolling on a temporal axis and thus causing time series [7,16].…”

“…Περισσότεροι τρόποι μέτρησης της μαθησιακής βελτίωσης όπως η αυτό-αξιολόγηση δεξιοτήτων, η διαφοροποίηση της ακαδημαϊκής εμπλοκής των φοιτητών (δηλαδή του βαθμού της φυσικής και πνευματικής προσπάθειας που καταβάλλουν στο πλαίσιο των σπουδών τους, Astin, 1984), αλλά και ποιοτικές μέθοδοι μέτρησης θα μπορούσαν να εφαρμοστούν στο μέλλον (Kandiko Howson, 2016). Επιπρόσθετα, η αξιολόγηση της συνεργασίας θα μπορούσε να γίνει και με μεθόδους που βασίζονται σε πραγματικό χρόνο (Chounta & Avouris, 2014). Προτείνεται λοιπόν, η διεξαγωγή επιπρόσθετων μελετών για τη διερεύνηση των προαναφερθέντων ζητημάτων.…”
