We are investigating automatic generation of a review (or survey) article in a specific subject domain. In a research paper, there are passages where the author describes the essence of a cited paper and the differences between the current paper and the cited paper (we call them citing areas). These passages can be considered as a kind of summary of the(More)
This paper introduces the Patent Mining Task of the Seventh TCIR Workshop and the test collections produced in this task. The task's goal was the classification of research papers written in either Japanese or English in terms of the International Patent Classification (IPC) system, which is a global standard. For this task, 12 participant groups submitted(More)
This paper introduces the Patent Mining Task at the Eighth NTCIR Workshop and the test collections produced in this task. The purpose of the Patent Mining Task is to create technical trend maps from a set of research papers and patents. We performed two subtasks: (1) the subtask of research papers classification and (2) the subtask of technical trend map(More)
Although stimulation of N-methyl-D-aspartate receptors or voltage-dependent calcium channels induces both the activation of c-fos and brain-derived neurotrophic factor (BDNF) genes, it is not certain how the activation of these genes is related. Using primary cultures of rat hippocampal neurons, we found that exposing the cells to cycloheximide allowed(More)
Collecting all the papers in a research field is a first step towards an exhaustive survey. A number of research paper databases are available for searching papers. However, searchers are compelled to repeat the same search operation for each database if there are multiple databases for a research field. To improve such inefficient searching, we have(More)
The history of the elemental technologies (underlying technologies) used in a particular research field is essential for anal yz-ing technical trend in the field. However, it is too costly and time-consuming to collect and read all of the papers in the field for the purpose of this analysis. Therefore, we have constructed a system that can recognize the(More)
In this paper, we describe a method for automatic acquisition of script knowledge from a Japanese text collection. Script knowledge represents a typical sequence of actions that occur in a particular situation. We extracted sequences (pairs) of actions occurring in time order from a Japanese text collection and then chose those that were typical of certain(More)
