Introduction The Community of Inquiry (CoI) framework was developed as a theoretical framework to support the practice and research of online learning. Garrison, Anderson, and Archer (2000) theorized that meaningful learning online takes place in a CoI made of teachers and students, through the interaction of three core elements: teaching presence, social presence, and cognitive presence. Over ...

The paper uses grounded theory to analyse the discourse on Indigenous Knowledge Systems within the South African government. Within this discourse, ICT is perceived both as a threat to African identity, through its potential facilitation of homogenisation and a potential ally, through its perceived potential to assist in the recording and dissemination of indigenous knowledge. The institutional...

One of the main challenges in the applications (i.e.: text summarization, question answering, information retrieval, etc.) of Natural Language Processing is to determine which of the several senses of a word is used in a given context. The problem is phrased as “Word Sense Disambiguation (WSD)” in the NLP community. This paper presents the dictionary based disambiguation technique that adopts t...

The current research into intrusion detection makes only the marginal use of results obtained by the community concerned with formal verification and testing. To harmonize the ideas and methods used by these two separate disciplines, we develop a discourse space (a taxonomy), in which the linguistic problems common to testing (in particular passive testing) and intrusion detection are captured....

The aim of the current paper is to formulate a conception of pragmatic patterns characterizing the construction of individual and collective identities in virtual communities (in our case: the Twitter community). We have explored several theoretical approaches and frameworks and relevant empirical data to show that the agents building virtual communities are 'extended selves' grounded in a high...

The identification of different nominal phrases in a discourse as used to refer to the same (discourse) entity is essential for achieving robust natural language understanding (NLU). The importance of this task is directly amplified by the field of Natural Language Processing (NLP) currently moving towards high-level linguistic tasks requiring NLU capabilities such as e.g. recognizing textual e...

In recent years, the Kappa coefficient of agreement has become the de facto standard to evaluate intercoder agreement in the discourse and dialogue processing community. Together with the adoption of this standard, researchers have adopted one specific scale to evaluate Kappa values, the one proposed in (Krippendorff, 1980). In this position paper, I highlight some issues that should be taken i...

Design science is a fundamental research stream that contends its position in the information systems discipline. While ongoing debates address the relative importance of design science contributions in the information systems community, insights into the scientific impact of design science research (DSR) are missing and this lack of understanding arguably poses challenges to an informed discou...

We will present Common Knowledge (CK) – a pedagogical and technological innovation that supports teacher orchestration of inquiry discourse occurring in the digital and classroom environments. We designed CK to support a “knowledge community” pedagogy where students add their own ideas, build on peers’ contributions, and structure their inquiry. Using tablets, students contributed to a knowledg...

The goal of argumentation mining, an evolving research field in computational linguistics, is to design methods capable of analyzing people’s argumentation. In this article, we go beyond the state of the art in several ways. (i) We deal with actual Web data and take up the challenges given by the variety of registers, multiple domains, and unrestricted noisy user-generated Web discourse. (ii) W...
