This paper focuses on analyzing (Japanese) splogs based on various characteristics of keywords contained in them. We estimate the behavior of spammers when creating splogs from other sources by analyzing the characteristics of keywords contained in splogs. Since splogs often cause noises in word occurrence statistics in the blogosphere, we assume that we(More)
This paper studies how to reduce the amount of human supervision for identifying splogs / authentic blogs in the context of continuously updating splog data sets year by year. Following the previous works on active learning, against the task of splog / authentic blog detection, this paper empirically examines several strategies for selective sampling in(More)
The motion of the lower limbs in bipedal walking is characterized by a foot-rolling motion, including heel-strike and toe-off. In this paper, the dynamical influence of this motion on walking stability is examined using a simple walking model driven by a rhythmic signal from an internal oscillator. In order to model the rolling motion, a circular arc is(More)

We study complementary navigation of news and blog, where Wikipedia entries are utilized as fundamental knowledge source for linking news articles and blog feeds/posts. In the proposed framework, given a topic as the title of a Wikipedia entry, its Wikipedia entry body text is analyzed as fundamental knowledge source for the given topic, and terms strongly(More)
Approximate computing has been studied widely in computing systems ranging from hardware to software. Approximate computing is a paradigm for reducing execution time and power consumption by tolerating some quality loss in computed results. On the other hand, we have proposed a processor called auto-memoization processor which is based on computation reuse.(More)
In the United States alone approximately 60,000 people are diagnosed with Parkinson’s disease each year, in addition to the estimated 10 million people already diagnosed worldwide. Parkinson’s has no known cure. While there are drugs to reduce the intensity of some symptoms, others are not treatable through this method. One such symptom known as “freezing(More)
The effect of emitted electron from carbon nanotube (CNT), of which shape is easy to emit electrons, on the X-ray intensity radiated using a polarized pyroelectric single crystal of LiNbO<inf>3</inf> was investigated at an air pressure of approximately 7&#x00D7;10<sup>&#x2212;3</sup> Pa. The negatively charged surface of the crystal was placed opposite an(More)
