The paper describes our pilot project for detecting those factors which could affect the reading from screen. Because entire course in the computer-based education cannot be always presented with multimedia elements, it is important to make a textual part of a curriculum easy and effective to read. We present an application, developed at Subotica Tech, which purpose is to find relations between students'...
So far there are a number of computer assisted assessment approaches that are based on a variety of features. However, those approaches exploit the whole set of training documents in order to assess a provided free-text answer against a given question. Recent text classification approaches are orientated to mine average class documents and consequently they provide cheap classification methods that...
In Information Retrieval (IR), the similarity scores between a query and a set of documents are calculated, and the relevant documents are ranked based on their similarity scores. IR systems often consider queries as short documents containing only a few words in calculating document similarity score. In Computer Aided Assessment (CAA) of narrative answers, when model answers are available, the similarity...
Aiming at emotional illiteracy in current e-learning environment, this paper discussed the reason why this situation happens. A research and application framework of recognizing emotion based text interaction is presented. An emotion category model for e-Learners is defined. Many Chinese metaphors are abstracted from corpus according to the sentence semantic and syntax. A method is applied to identify...
Based on the clustering technology in data mining, we aimed to establish a new schoolwork identifying mechanism. In order to let the normal answer can adapt to actual situations better, we first generalized the normal answer, and then calculated the similarity between every sample and normal answer, as well as similar degree between school works. Based on the similarity, we clustered all school work...
The use of language in free text answers provides an excellent means for assessment, but it is hard work to mark this type of material. The automatic assessment of open questions can be applied successfully to carefully written literal text explicit and literal text implicit questions, both categories very frequent in engineering. Existing automatic marking systems exhibit results comparable to manual...
Willow is a Web-based application which automatically and adaptively assesses students' free-text answers written in Spanish and English. It is intended to help students review concepts outside of class, and provides an alternative assessment method. However, students tend to be greatly concerned by computer generated scores and, although they have been told that the system is not intended for summativepurposes...
