This paper addresses the ongoing issue of tone error detection for Mandarin Computer Assisted Language Learning (CALL) systems. A novel approach based on clustering is proposed. The selection of different contextual tonal factors including Uni-tone, LBi-tone and RBi-tone are explored. Experimental results show that our proposed approach is feasible, obtaining an Equal Error Rate (EER) of 18.75% by...
The complexity of web applications becomes a big problem, when applications are growing. Especially if new algorithms should be tested and compared, it is important to be able to separate the newly implemented functions from the core system. It is not enough to use standard frameworks to handle this, but to plan a maintainable structure for the application. This paper describes how a maintainable...
Foreign students who live and study in China encounter many problems in Chinese language learning, as language learning often correlates with background knowledge which varies from country to country caused by cultural and social differences in terms of distinct public policies and services. With the increasing number of foreign students in China and the great demand for mobile Chinese language learning...
The possibility of using MOODLE e-learning platform as an environment for education of database issues, concerning basic database objects and users creating, analysis and transaction management was analyzed in the paper. All of needed extensions were made using php scripts and were tested in the chosen database servers: MySQL, SQL Server and Oracle DBMS. Results of these tests were satisfactory, confirming...
The paper is directed by constructivism theory, combined by the practical characteristic of programmer courses, brings forward an “incomplete” assistant teaching system, and expatiates on the ideology, model and overall design of this system. The practice proves that the “incomplete” assistant teaching system based on the constructivism is a new approach to improve teaching quality.
The intelligent help system (IHS) is an important assistant platform, especially in online teaching system. At present most search methods of the help systems are mainly based on keyword matches in database query or hierarchical classifications. The outstanding problem is that users are required to have a certain ability of organizing Keywords, otherwise insufficient keywords would limit the query,...
A lot of content for tele-lecturing portals was produced in the last decade. But metadata to filter the content was not generated adequately. It therefore takes a long time for users to filter through all the videos available until they find the learning content they are looking for. That is why it is a new challenge to find solutions how to filter the large amount of data with a small base of metadata...
Current learning systems are frequently criticized for their predominant focus on explicit, and in particular, written representation of knowledge. There are communities around the world where verbal knowledge is more pervasive than written knowledge. This paper presents a study of how such knowledge can be accessed anywhere/anytime, in a form that may be used and understood in a standardized format,...
Internet has become the essential platform for access, processing and dissemination of scientific data and literature. To greatly enhance academic search, a novel academic metasearch engine called e-Scholar is presented in this paper, which is combined with entity extraction techniques to link the relevant data in scientific databases with the literature. We demonstrate a scalable architecture implementing...
Within the MACE project, we support simple access to and retrieval of digital learning resources in exploratory architectural education. In order to facilitate the improved access, we introduce a digital representation of real world objects through an extension of the LOM based MACE application profile, named entity recognition and the combination of various databases. Automatically grouping learning...
This article presents a concept model, and the associated tool to help advanced learners to find adapted bibliography. The purpose is the use of an IT representation as educational research software for newcomers in research. We use an ontology based on the ACM's Computing Classification System in order to find scientific articles directly related to the new researcher's domain without any formal...
In this paper, we describe a system for correcting English preposition errors automatically. Non-native English writers often make these errors. Our system uses rules extracted automatically based on preposition context features, such as preceding and following nouns. Additional rules are generated recursively from the extracted rules using inductive learning. Our system achieves 82% accuracy and...
Delivering learning and education is the most invaluable building block in today's knowledge-based society. The emergence of learning objects in learning technology has had a big impact on the learning environment and its community. Teachers and students have more facilities for using the e-learning system, which has made the learning process more effective. This paper presents development of learning...
