The purpose of the experiment on collaborative memory was to investigate if the collaborative inhibition is due to collaborating pair's disruption of each others' retrieval strategies (the retrieval strategy disruption hypothesis, RSD). The participants' (N = 36) task was to recall a list of 60 words individually and collaboratively. Retrieval strategies were manipulated by presenting word list...

People-to-people recommendation differ from item recommendations in a number of ways, one of which is that individuals add information to their profile which is often critical in determining a good match. The most critical information can be in the form of free text or personal tags. We explore text-mining techniques to improve classical collaborative filtering methods for a site aimed at match...

Linguistic annotation is the process of adding additional notations to raw linguistic data for descriptive or analytical purposes. In the tagging of complex Chinese and multilingual linguistic data with a sophisticated linguistic framework, immediate visualization of the complex multi-layered functional and discourse structures is crucial for both speeding up the tagging process and reducing er...

The completion mode (individual, collaborative) of the tasks and the conditions under which these modes are performed have been reported to play an important role in language learning. The present study aimed to investigate the effects of employing text editing tasks performed both individually and collaboratively, on the achievement of English grammar under explicit and implicit learning condi...

E-learning is popularized so fast and Collaborative Learning (CL) becomes so important an instructional strategy. There are huge Group Session (GS) texts needed to be analyzed to evaluate CL, thus the automatic or semi-automatic methods of analyzing the GS texts become very important. In this paper we present a method called Interaction Analysis depended on Knowledge Extraction (IAKE) to analyz...

Synchronisation of replicated shared data is a key issue in collaborative writing systems. Most existing synchronization tools are specific to a particular type of shared data, i.e. text files, calendars, XML files. Therefore, users must use different tools to maintain their different copies up-to-date. In this paper we propose a generic synchronization framework based on the operational transf...

Online text chat is a very popular Internet-based application. Previous studies have identified several problems with standard text chat systems. Real-time collaborative editing systems can be used for text chat. This paper compares text chat via collaborative editing systems with text chat via standard text chat systems. It has been identified that standard text chat system do not maintain som...

The need for computer-supported collaboration has grown over the last years and made collaboration an important factor within organizations. This trend has resulted in the development of a variety of tools and technologies to support the various forms of collaboration. Many collaborative processes, e.g. strategy building, scenario analysis, root cause analysis and requirements engineering, requ...
