A large body of research in machine learning is concerned with supervised learning from examples. The examples are typically represented as vectors in a multi-dimensional feature space (also known as attribute-value descriptions). A teacher partitions a set of training examples into a finite number of classes. The task of the learning algorithm is to induce a concept from the training examples....

A rarely discussed but important issue in research on pragmatic inference is the choice of dependent measure for estimating the robustness of pragmatic inferences and their sensitivity to contextual manipulations. Here we present the results from three studies exploring the effect of contextual manipulations on scalar implicature. In all three studies we manipulate the salient question under di...

Contextual suggestion aims to provide a user with venues that are relevant to his/her preferences and context. Most existing approaches only take into account those two features in order to build their suggestion list. However, research in recommender systems recently stressed the importance of diversified suggestions. This paper introduces a novel model for contextual suggestion based on compo...

The Information Security Policy (ISP) of an organisation is expected to specify for employees their behaviour towards security, and the security ethos of the organisation. However, there are a wide range of opinions and expertise that should be considered by organisations when developing an ISP. This paper aims to identify the stakeholders that should be utilised in an ISP development process a...

Contextual advertising systems suggest suitable advertisings to users while surfing the Web. Focusing on text summarization, we propose novel techniques for contextual advertising. Comparative experiments between these techniques and existing ones have been performed.
