"A comparison of methods for detecting hot topics"
In scientometrics for trend analysis, parameter choices for observing trends are often made ad hoc in past studies. For examples, different year spans might be used to create the time sequence and different indices were chosen for trend observation. However, the effectiveness of these choices was hardly known, quantitatively and comparatively. This work provides clues to better interpret the results when a certain choice was made. Specifically, by sorting research topics in decreasing order of interest predicted by a trend index and then by evaluating this ordering based on information retrieval measures, we compare a number of trend indices (percentage of increase vs. regression slope), trend formulations (simple trend vs. eigen-trend), and options (various year spans and durations for prediction) in different domains (safety agriculture and information retrieval) with different collection scales (72500 papers vs. 853 papers) to know which one leads to better trend observation. Our results show that the slope of linear regression on the time series performs constantly better than the others. More interestingly, this index is robust under different conditions and is hardly affected even when the collection was split into arbitrary (e.g., only two) periods. Implications of these results are discussed. Our work does not only provide a method to evaluate trend prediction performance for scientometrics, but also provides insights and reflections for past and future trend observation studies.
"The Asia-Pacific Perspectives" is an open forum and welcomes the submission of analyses and commentaries on the Asia-Pacific region. It is published four times a year by the Chinese Taipei Pacific Economic Cooperation Committee. The periodical focuses on political, economic, business and cultural matters. In this inaugural issue, the spotlight is on various aspects of Asia-Pacific regional architecture.

"The Study on Korean and Taiwanese Investment Patterns in China" is the most recent research paper produced by a joint project between Samsung Economic Research Institute (SERI) and TIER. This paper has discussed about Korean and Taiwanese firmsˇ¦ current investment patterns in China, both countriesˇ¦ historical and present investment cooperation with China, and how investment in China has influenced Korea and Taiwanˇ¦s domestic economy. Taking changes in modern China into account, this paper has also provided an insightful analysis on opportunities for further cooperation between Korea and Taiwan.
