A novel bootstrapping approach to Named Entity (NE)tagging using concept-based seeds and successive learners is presented. This approach only requires a few common noun or pronoun seeds that correspond to the concept for the targeted NE, e.g. he/she/man/woman for PERSON NE. The bootstrapping procedure is implemented as training two successive learners. First, decision list is used to learn the ...

The next decade will see an abundance of new intelligent systems, many of which will be market-based. Soon, users will indirectly interact with many markets without knowing it: when driving their car, when listening to a song, when talking on the phone, when backing up their files, or even when surfing the web. I argue that these new systems can only be successful if a new approach is chosen to...

Purpose The purpose of this study is to evaluate the effect learner–learner and learner–facilitator interactions on learner satisfaction their substitutability. Design/methodology/approach A quantitative survey research focusing 130 students was used collect data. Stratified sampling preferred for study, with a Likert type instrument being administered online. Findings Learner–learner mediate e...

Some heterodox economists, most notably Tony Lawson, have come under suspicion of not being true pluralists, but ‘strategic pluralists’: their advocacy of pluralism is thought to be merely instrumental to a hidden monist agenda. This paper does not aim to judge the accused but rather to assess the accusations; the focus is on clarifying the notion of pluralism itself. First a paradox is found t...

E-learning implementations have become an important agenda item for academic and business institutions as an enabler to complement their education and training needs. However, many of the existing e-learning systems, present several limitations such as them being static, passive and consisting of a time-consuming set of services. This has highlighted the need for functionality, which allows mor...

Introduction Integrated Disease Surveillance and Response (IDSR) is a World Health Organization (WHO) Regional Office for Africa (AFRO) strategy for strengthening national public health surveillance and response systems in African countries. The strategy incorporates the International Health Regulations (2005) core capacities for public health surveillance and response systems1. Since 2010, mor...

Technology-assisted learning has become increasingly crucial for academic studies and corporate training. E-learning has potentially become one of the most significant developments in the information systems and technologies. Motivated by such compelling advantages as geographical reach, learner control, and cost effectiveness in course delivery and management, educational institutions and prof...

Learner corpora are receiving special attention as an invaluable source of educational feedback and are expected to improve teaching materials and methodology. However, they include various types of incorrect sentences. Error type classification is an important task in learner corpora which enables clarifying for learners why a certain sentence is classified as incorrect in order to help learne...

This paper presents the open learner modelling capabilities offered by an adaptive web testing tool. Adaptation decisions are based on user customizable compound rules requiring the identification of several learner characteristics which are then displayed graphically and textually to learners and educators. The open learner modelling capabilities include anonymous access to models of peers and...
