The MWK is obtained by incorporating the wavelet technique and manifold theory into SVM. Unlike Gaussian kernel in SVM, the MWK can approximate arbitrary nonlinear functions. The applicability and validity of MWK for volatility forecast are confirmed through experiments on simulated data sets.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122162018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital archives have been built up in almost every level of Chinese government hierarchy. The structure features of the archives in Chinese government are discussed first in this paper. Then, it proposes a practical approach for text mining of these semi-structured archives. With the help of Semantic Web related technology, knowledge extracted through mining can be stored and managed in ontology base for administrators, and can be retrieved through ontology presentation system for end-users. Finally, a case study in a provincial archives bureau of China is introduced, which shows that knowledge among the archives especially dynamic knowledge can be easily mined and utilized in this way. It helps a lot in policy making, emergency decision support, and government routines.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"91 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128013397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Annual production, document type, language distribution of publications, page count, number of references, geographical distribution of research output, and key words in traffic flow filed were performed. The results indicated that English was the dominant language; eight-page papers (347, 8.97%) dominated most of the documents; the average documents published per journal was 3.79; collaboration of one to four authors was the most popular level of co-authorship; the most prolific author was Nagatani,T with 112.435 total impact factor; the authors came from 84 countries; USA is the top producing country with 1359 publications of the total output; there were eight keywords with frequency over 100 times; the highest frequency keyword was traffic flow with 378(12.52%).","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"310 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124407280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study two important facts: the allocation of market share and service radius of facilities. The utility function is the most important function for allocation the market share by a retail facility in a competitive environment. Conjunction with the spatial customer choice, we define a step utility function which is used to constitute a new model of a chain-company’s new facilities location in competitive environment. Both the decay cover and the service radius of facilities are considered in the model. The genetic algorithm to solve this model is developed and computational experiment is described. It is showed that this model and algorithm can apply to the location decision of the chain-company’s new facilities, and can efficiently obtain an approximate solution.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131896953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
