In this paper, we present an investigation into the use of cue phrases as a basis for dialogue act classification. We define what we mean by cue phrases, and describe how we extract them from a manually labelled corpus of dialogue. We describe one method of evaluating the usefulness of such cue phrases, by applying them directly as a classifier to unseen utterances. Once we have extracted cue p...

Identifying events of a specific type is a challenging task as events in texts are described in numerous and diverse ways. Aiming to resolve high complexities of event descriptions, previous work (Huang and Riloff, 2013) proposes multi-faceted event recognition and a bootstrapping method to automatically acquire both event facet phrases and event expressions from unannotated texts. However, to ...

However, none has studied the potentially positive effects of slightly interactive media for rousing drowsy drivers to he...

We aimed to elucidate why cockroaches do not produce vitellogenin in immature stages, by studying the appearance of vitellogenin mRNA in larvae of Blattella germanica. Treatment of female larvae in any of the last three instars with 1 microg of juvenile hormone (JH) III induces vitellogenin gene transcription, which indicates that the fat body is competent to transcribe vitellogenin at least fr...

Phrases are used in both commercial and experimental search engines. Despite the large amount of work in the area results remain mixed. It is still not clear whether phrases can be used to improve retrieval effectiveness. In this paper, we examine phrases and their properties independently of any specific retrieval approach. We explore phrase usage in text corpora and relevance patterns related...

We study the problem of similarity between phrases. To do so, we study three similarity methods. The first one considers the commonalities and differences of the two phrases. The second one is an extension of the well-known Levenshtein-Damerau distance in a word oriented fashion. The third one considers the sequentiality of the phrases and is resistant to phrases with repeated words. Finally, w...
