In this paper we present a new term selection technique for document clustering. Classifiers are trained to recognize documents of one single topic. The technique is designed to maintain a predefined minimal precision, while maximizing the recall of the classification. The most useful terms are collected in a greedy way. The minimal precision is ensured due to a minimal document score for selec...

The increasing number of ontologies on the Web and the appearance of large scale ontology repositories has brought the topic of ontology selection in the focus of the semantic web research agenda. Our view is that ontology evaluation is core to ontology selection and that, because ontology selection is performed in an open Web environment, it brings new challenges to ontology evaluation. Unfort...

The development of the in vitro selection technique has allowed the isolation of functional nucleic acids, including catalytic DNA molecules (DNAzymes), from random-sequence pools. The first-ever catalytic DNA obtained by this technique in 1994 is a DNAzyme that cleaves RNA. Since then, many other RNase-like DNAzymes have been reported from multiple in vitro selection studies. The discovery of ...

Micro-blogging has become increasingly popular in recent years. Using micro-blogging in a large classroom could be beneficial for learning. However, sometimes addressing the large number of posts could be cumbersome to a reader who has only limited time in a classroom. We propose a novel solution for predicting the relevancy of a question asked in a class by looking at the questions asked in pr...

At the Caisse des Dépôts et Consignations (CDC), the Agence France-Presse (AFP) news releases are filtered continuously according to the users' interests. Once a user has specified a topic of interest, a filter is customized to fit this user's profile. Until now, these filters would rely on rule-based methods, whose efficiency is proven [Vichot et al., 1999], but which require a large amount of...

In this paper, we investigate an approach for creating a comprehensive textual overview of a subject composed of information drawn from the Internet. We use the high-level structure of human-authored texts to automatically induce a domainspecific template for the topic structure of a new overview. The algorithmic innovation of our work is a method to learn topicspecific extractors for content s...

This research forum pertains to the topic of subject selection in augmentative and alternative communication (AAC) research. The following two papers present opposing views on the use of nondisabled persons in AAC research. Specifically, Higginbotham (1995) offers an argument in favor of the use of nondisabled persons as subjects, while Bedrosian (1995) addresses current limitations in using th...
