This paper complements a series of works on implicative verbs such as manage to and fail to. It extends the description of simple implicative verbs to phrasal implicatives as take the time to and waste the chance to. It shows that the implicative signatures of verb-noun collocations depend both on the semantic type of the verb and the semantic type of the noun in a systematic way.

Reduplication has played a central role in the development of phonological theories for 30years. The introduction of Classical Optimality Theory (OT) in the 1990s sparked intensive research into the typology and analysis of reduplicative patterns, as reduplication was a key testing area both for OT and for theories critical of OT. Now, after some 20years of research within the OT model, it is a...

Speaker clustering is one of the major methods for speaker adaptation. MLLR (Maximum Likelihood Linear Regression) adaptation using transformation matrices corresponding to phone classes/clusters is another useful method especially when the length of utterances for adaptation is limited. In these methods, how to decide the most appropriate number of clusters is an important research issue. This...

TREC-9 evaluation experiments at the Justsystem site are described with a focus on “aboutness” based approach in text retrieval. Experiments on the effects of supplemental noun phrase indexing, pseudo-relevance feedback and reference database feedback in view of the effect of various length of queries are reported. The results show that pesudo-relevance feedback is always effective while refere...

We present a system for the automatic extraction of salient information from email messages, thus providing the gist of their meaning. Dealing with email raises several challenges that we address in this paper: heterogeneous data in terms of length and topic. Our method combines shallow linguistic processing with machine learning to extract phrasal units that are representative of email content...

Statistical learning methods offer a route for identifying linguistic constructions. Phrasal constructions are interesting both from the viewpoint of cognitive modeling and for improving NLP applications such as machine translation. In this article, an initial model structure and search algorithm for attempting to learn constructions from plain text is described. An information-theoretic optimi...

Automatic paraphrasing is a transformation of expressions into semantically equivalent expressions within one language. For generating a wider variety of phrasal paraphrases in Japanese, it is necessary to paraphrase functional expressions as well as content expressions. We propose a method of paraphrasing of Japanese functional expressions using a dictionary with two hierarchies: a morphologic...
