In this paper, we develop an algorithm to mine message boards, e.g., Yahoo! Clubs. Each message is evaluated by three indices: (i) the degree of inclusion of given information, (ii) the degree of inclusion of new information, and (iii) the degree of effect for the successive messages. We show these indices are useful for characterizing a message. We also show a prototype system of summarization...

the objective of this study is to develop a novel methodology integrating remote sensing, geographic information system technology and local spatial autocorrelation geo-computation for quick drought assessment. one group of drought indices, based on the condition of the vegetation, includes the normalized difference vegetation index (ndvi), anomaly of normalized difference vegetation index (ndv...

View angle effects present in vegetation indices are either being seen as unwanted information or as an additional source of information. However, the magnitude of these angular effects remains for most indices unknown. We use the ESA-mission CHRISPROBA (Compact High Resolution Imaging Spectrometer–Project for On-board Autonomy) providing spaceborne imaging spectrometer and multidirectional dat...

In recent years, network teaching platform has been more and more popular. First, this article describes the development of domestic and international network teaching platform. Second, the development of network teaching platform in Jiangxi province is introduced. Third, the literatures on the evaluation of web sites’ quality are reviewed. Finally, the quantitative evaluation system is propose...

In this paper, we evaluate the uniqueness of several information-theoretic measures for graphs based on so-called information functionals and compare the results with other information indices and non-information-theoretic measures such as the well-known Balaban J index. We show that, by employing an information functional based on degree-degree associations, the resulting information index out...

Two new feature selection methods are introduced, the first based on separability criterion, the second on consistency index that includes interactions between the selected subsets of features. Comparison of accuracy was made against information-theory based selection methods on several datasets training neurofuzzy and nearest neighbor methods on various subsets of selected features. Methods ba...
