  • This paper presents a status quo of an ongoing research study of collocations – an essential linguistic phenomenon having a wide spectrum of applications in the field of natural language processing. The core of the work is an empirical evaluation of a comprehensive list of automatic collocation extraction methods using precision-recall measures and a proposal of a new approach integrating multiple basic methods and statistical classification.

  • In this paper, we describe an empirical study of Chinese chunking on a corpus, which is extracted from UPENN Chinese Treebank-4 (CTB4). First, we compare the performance of the state-of-the-art machine learning models. Then we propose two approaches in order to improve the performance of Chinese chunking. 1) We propose an approach to resolve the special problems of Chinese chunking. This approach extends the chunk tags for every problem by a tag-extension function. 2) We propose two novel voting methods based on the characteristics of chunking task.

  • The conquest of Mexico, an extensive empire with a numerous and warlike population, by a mere handful of Spaniards, is one of the romances of history. Indeed, a writer of fiction would scarcely have dared to invent so improbable a story. Even the bravery of the Spaniards, and the advantage of superior arms would not have sufficed to give them the victory, had it not been that Mexico was ripe for disruption.

  • Whether we get forms with extensive clarity by use of Baumgarten’s aesthetic considerations can not be answered conclusively on these cases, because much indicate that it has given some vague ideas when students encounter these considerations during evaluations, but without putting them into real use in their leading feature or as a guidelines in the design process. However, to the question: How can designers formulate aesthetic considerations which communicate a clear message to other professionals? an obvious answer is to make use of Baumgarten’s aesthetic considerations. ...

  • Although there is an extensive body of research concerned with anaphora resolution (e.g. (Fox, 1987; Grosz et al., 1995)), event anaphora has been widely neglected. This paper describes the results of an empirical study regarding event reference. The experiment investigated event anaphora in narrative discourse via a sentence completion task. The results of the experiment suggest that the discourse structure established by an explanation or elaboration relation has an influence on whether the last mentioned event, previously mentioned events or a complex event is preferably referred to.

  • This study investigates the hypothesis that shifts in women’s relative income, which affects their bargaining power in the household, have discernible effects on household saving, and by extension on aggregate saving due to differing saving propensities by gender. An analytical framework for pooled and non-pooled savings households is developed to examine why women and men’s saving propensities may differ and how a change in women’s wage earnings relative to men’s influences household savings which constitutes a significant component of gross domestic saving.

  • The effect of wealth on consumption has been studied extensively in the empirical literature on consumption functions. In this section we provide a brief overview of the findings of these studies. 2 Few studies have examined the relationship between consumption and total wealth for Australia. Tan and Voss (2003) have estimated the marginal propensity to consume (MPC) out of total wealth at 0.04 or, in other words, that long-run annual consumption increases by 4 cents in response to a one dollar increase in wealth. Bertaut (2002) puts this number marginally higher at 0.05.
