This paper presents a new bootstrapping approach to named entity (NE) classification. This approach only requires a few common noun/pronoun seeds that correspond to the concept for the target NE type, e.g. he/she/man/woman for PERSON NE. The entire bootstrapping procedure is implemented as training two successive learners: (i) a decision list is used to learn the parsing-based high precision NE...

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

Pairwise clustering, in general, partitions a set of items via a known similarityfunction. In our treatment, clustering is modeled as a transductive predictionproblem. Thus rather than beginning with a known similarity function, the functioninstead is hidden and the learner only receives a random sample consisting of asubset of the pairwise similarities. An additional set of pai...

Nowadays, instructional technologies are the enabler for educators to have more choices in course planning, course design, and lecturing. These technologies not only strengthen the communication between instructors and learners, but also let the learners get an easily access their course materials at anytime and from anywhere. As a result, many educational institutes, including formal universit...

We have implemented ubiquitous computing technology in a primary school setting to support rich classroom activities particularly in the field of early literacy. After initial tests have corroborated the benefit of this technology with respect to attaining curricular goals and to better supporting learner-centred classroom methodologies, we are now exploring specific intelligent support mechani...

An extensive analysis of the college teaching literature (over 350 items) suggests that the perspective of perhaps the most highly effective college teachers has yet to be conceptualized, at least within a comprehensive developmental framework. This paper articulates that perspective-called here Systemocentrism (or teacher/learner-centeredness). The perspective b two distinctive elements-attent...

A learner corpus is a useful resource for developing automatic assessment techniques for implementation in a computer-assisted language learning system. However, presently, learner corpora are only helpful in terms of evaluating the accuracy of learner output (speaking and writing). Therefore, the present study proposes a learner corpus annotated with evaluation results regarding the accuracy a...
