An important part of the project is to store questions from different systems in a question exchange database and make it accessible for all project partners. Since there is currently no well-functioning option for this, we decided to develop an extension for integration into our question exchange platform. For this purpose, a new Moodle plugin was developed at BTU Cottbus - Senftenberg that converts questions from the QTI 2.1 standard into Moodle XML and vice versa. The aim was to convert as many question types as possible free of loss. For this purpose, questions from various systems that work with the QTI standard were made available and tested for the possibility of lossless conversion. The result is the prototype of a plugin that can convert eight different question types. In this article we present the first prototype of the plugin.}, language = {en} } @misc{KutznerTraviesoGonzalezBoenningeretal., author = {Kutzner, Tobias and Travieso-Gonz{\´a}lez, Carlos M. and B{\"o}nninger, Ingrid and Pazmi{\~n}o-Zapatier, Carlos F. and Plath, Wolf-Dietrich and Gebhard, Matthias}, title = {Writer Identification Using Handwritten Cursive Texts and Single Character Words}, series = {Electronics}, volume = {8}, journal = {Electronics}, number = {4}, issn = {2079-9292}, doi = {10.3390/electronics8040391}, pages = {25}, abstract = {One of the biometric methods in authentication systems is the writer verification/identification using password handwriting. The main objective of this paper is to present a robust writer verification system by using cursive texts as well as block letter words. To evaluate the system, two datasets have been used. One of them is called Secure Password DB 150, which is composed of 150 users with 18 samples of single character words per user. Another dataset is public and called IAM online handwriting database, and it is composed of 220 users of cursive text samples. Each sample has been defined by a set of features, composed of 67 geometrical, statistical, and temporal features. In order to get more discriminative information, two feature reduction methods have been applied, Fisher Score and Info Gain Attribute Evaluation. Finally, the classification system has been implemented by hold-out cross validation and k-folds cross validation strategies for three different classifiers, K-NN, Na{\"i}ve Bayes and Bayes Net classifiers. Besides, it has been applied for verification and identification approaches. The best results of 95.38\% correct classification are achieved by using the k-nearest neighbor classifier for single character DB. A feature reduction by Info Gain Attribute Evaluation improves the results for Na{\"i}ve Bayes Classifier to 98.34\% for IAM online handwriting DB. It is concluded that the set of features and its reduction are a strong selection for the based-password handwritten writer identification in comparison with the state-of-the-art.}, language = {en} } @misc{KutznerMeissnerNesterowetal., author = {Kutzner, Tobias and Meißner, Marlen and Nesterow, Igor and Rojas, Pedro and Freytag, Andreas}, title = {Concept of a cross-university question exchange platform with Moodle LMS}, series = {VII Jornadas Iberoamericanas de Innovaci{\´o}n Educativa en el {\´A}mbito de las TIC y las TAC, Las Palmas de Gran Canaria, 19 y 20 de noviembre de 2020}, volume = {2020}, journal = {VII Jornadas Iberoamericanas de Innovaci{\´o}n Educativa en el {\´A}mbito de las TIC y las TAC, Las Palmas de Gran Canaria, 19 y 20 de noviembre de 2020}, edition = {7.
