Hui-Chin Yeh, National Yunlin University of Science and Technology Collaborative writing (CW) research has gained prevalence in recent years. However, the ways in which students interact socially to produce written texts through synchronous collaborative writing (SCW) is rarely studied. This study aims to investigate the effects of SCW on students’ writing products and how collaborative dialogu...

E-cognocracy (Moreno-Jiménez, 2003, 2004, 2006; Moreno-Jiménez & Polasek, 2003, 2005) is a new democratic system that adjusts traditional or representative democracy to meet the needs and challenges of the Knowledge Society. If e-democracy is understood as the government of the people by means of information and communication technology (ICT), e-cognocracy is the government of knowledge and wis...

The probabilistic graphs framework models the uncertainty inherent in realworld domains by means of probabilistic edges whose value quantifies the likelihood of the edge existence or the strength of the link it represents. The goal of this paper is to provide a learning method to compute the most likely relationship between two nodes in a framework based on probabilistic graphs. In particular, ...

Collaborative learning enables participants in a learning community to externalize and share knowledge, experiences, and practice. However, collaborative learning in an online environment can be challenging due to the lack of face-to face interaction. This current study examined twenty graduate students’ experiences of using VoiceThread for a collaborative activity in an entirely online course ...

Most existing cross-domain recommendation algorithms focus on modeling ratings, while ignoring review texts. The review text, however, contains rich information, which can be utilized to alleviate data sparsity limitations, and interpret transfer patterns. In this paper, we investigate how to utilize the review text to improve cross-domain collaborative filtering models. The challenge lies in t...

TeNDaX is a collaborative database-based real-time editor system. TeNDaX is a new approach for word-processing in which documents (i.e. content and structure, tables, images etc.) are stored in a database in a semi-structured way. This supports the provision of collaborative editing and layout, undoand redo operations, business process definition and execution within documents, security, and aw...

Wikis are well-known for supporting collaborative writing. They are focusing on asynchronous collaboration. Today, synchronous text editing in the web is supported by several tools and approaches. However, this possibility is still missing in wikis. Based on a prototype implementation, this paper presents design considerations for a wiki integrating synchronous collaborative editing as a specia...

Writer-based and reader-based views of text-meaning are reflected by the respective questions “What is the author trying to tell me?” and “What does this text mean to me personally?” Contemporary computational linguistics, however, generally takes neither view. But this is not adequate for the development of sophisticated applications such as intelligence gathering and question answering. I dis...

Many student interactions in the collaborative learning process can be captured and stored in a database for future analysis. However, the precious information extraction in database is almost impossible without the use of mining techniques. In this paper we present a model of collaborative learning, individual and group, using data and text mining techniques. Our model allows us to extract rel...
