Text classification is an important research problem in many fields. We examine a special case of textual content namely, short text. Examples of short text appear in a number of contexts such as online reviews, chat messages, twitter feeds, etc. In this research, we examine short text for the purpose of classification in internet auctions. The “ask seller a question” forum of a large horizonta...

The relationship between collaboration processes, task strategies and the use of the tools and resources that the computer environment offers, may be crucial for the effects of computer supported collaborative learning. We are interested to find out how, within a computer environment, students collaborate, how they use the different tools we offer and how this influences the quality of the fina...

The Internet has created an environment where many technologies are used to provide net-based customer services. Recently, Online Live Chat Customer Service (OLCCS) has been adopted widely and rapidly on many websites. OLCCS extends traditional customer service channels by using live chats to deliver real-time help and on-demand assistance to online customers’ inquiries. The purpose of this dis...

In online computer-mediated communication, speakers were considered to have experienced difficulties in catching their partner’s emotions and in conveying their own emotions. To explain why online emotional communication is so difficult and to investigate how this problem should be solved, multimodal online emotional communication corpus was constructed by recording approximately 100 speakers’ ...

This study aimed to clarify the relationship between media, learners’ perception of social presence, and output in communicative learning using synchronous computer-mediated communication (SCMC). In this study, we developed four types of SCMC: videoconferencing (image and voice), audioconferencing (voice but no image), text chat with image (image but no voice), and plain text chat (no image and...

This thesis addresses a natural language processing problem posed in the context of so-called Web assistant systems aka live help systems. A recent feature added to a growing number of Web sites, such systems o er user support via text chat with human assistants. To adapt consultation to the individual user, long-term information about his or her skills and interests is collected in a user mode...

Equipped with advanced features, people can use it for education, business and socialize...

This paper introduces an approach for using a swarm intelligence algorithm, Stochastic Diffusion Search (SDS) – inspired by one species of ants, Leptothorax acervorum – in order to generate music from plain text. In this approach , SDS is adapted in such a way to vocalise the agents, to hear their “chit-chat” . While the generated music depends on the input text, the algorithm’s search capabili...

The analysis of text in the form of tweets, chat or posts can be an interesting as well as challenging area of research. In this paper, such an analysis provides information about the human behavior as positive, negative or neutral. For simplicity, tweets from social networking site, Twitter, are extracted for analyzing human personality. Various concepts from natural language processing, text ...
