Compare to speech signals, the throat signals have many differences in the amount of information. In this context, targeting on throat signals to find valid frequency range is one of the most important analyses for the development of new breed of feature extraction algorithm. In this respect, using analysis similarity of throat signals feature distribution and correlation analysis of throat signals in the frequency domain, the frequency range can be found with effective and quick response time to be applied to a voice command recognition system using neck-microphone. As a result, the proposed frequency range is from 200Hz(center frequency) to 2001Hz(center frequency). For the neck-microphone voice command system using the proposed frequency range, a significant reduction in time complexity of 25% can be achieved without any loss in recognition rate.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127788298","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}

The general public accepts information not only by mass media but also by opinion leaders. Since the late 20th century, the number of Internet users has increased fast. Many users interact with each other in an online social network. This makes the Web community similar to the real society. Thus it is a natural task to find influential users in an online society. For example, many online articles posted by influential bloggers are used as marketing tools for companies or political advertisements for parties since these articles have huge influence to other users. We first revisit the previous researches on finding influential users in online society. Then we compose test sets from the GroupLens movie database and identify representative reviewers. Next, we show the validity of the chosen representative reviewers and test the reliability using the 10-fold cross- validation. Finally, we explain applicability of the proposed approach to improve current recommendation systems.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132547233","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}

For WSNs, various medium access control (MAC) protocols with different objectives have been proposed. Designing energy-efficient MAC protocols has a significant influence on the network lifetime in WSNs. However, short sensing ranges result in dense networks and thus it becomes necessary to achieve an efficient MAC protocol subject to energy constraints. In this paper, we study the energy efficiency of typical MAC protocols in WSNs systematically. The MAC protocols are categorized into contention-based, TDMA-based, hybrid, and cross layer MAC protocols according to channel access policy, and their pros and cons are qualitatively compared. Then, the typical MAC protocols are evaluated in terms of energy efficiency using the ns-2 network simulator and compared to each other quantitatively.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133857783","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}

The ever increasing demand of finding pattern from large data enhances the association rule mining. Researchers developed a lot of algorithms and techniques for determining association rules. The main problem is the generation of candidate set. Among the existing techniques, the frequent pattern growth (FP-growth) method is the most efficient and scalable approach. It mines the frequent item set without candidate set generation. The main obstacle of FP growth is, it generates a massive number of conditional FP tree. In this research paper, we proposed a new and improved FP tree with a table and a new algorithm for mining association rules.

The purpose of this study is to enhance the web services in consideration of the functional aspects by suggesting a practical level decision making reflecting the functional and non-functional aspects using WSDL and meta-data upon the web services. For this purpose, the execution costs, reliability, and the quality level from the non-functional aspects of the existing studies are used to extract and save the detailed and clearly defined meta-data to record the non-functional elements.

In this paper, we simulate PBLE in various environments of realistic WSNs. Additionally, we use node scheduling method for prolonging lifetime of WSN.

Currently, there is also no way to use DBSCAN with different parameters for different cluster when it is applied to anomaly detection when network traffic includes multiple traffic types with different characteristics. In this paper, we propose a new way of finding DBSCAN's parameters and applying DBSCAN with those parameters. Each cluster may have different epsilon and minpts values in our algorithm. The algorithm is called DBSCAN-MP. We also propose a mechanism of updating normal behavior by updating size or creating new clusters when network environment is changing overtime. We evaluate proposed algorithm using the KDD Cup 1999 dataset. The result shows that the performance is improved compare to other clustering algorithms.","PeriodicalId":425210,"journal":{"name":"2011 International Conference on Information Science and Applications","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124732911","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}

Thus, our system applies spatial relation rules and ontology for object recognition if a viewer is interested in one on the screen of TV program such as drama, movie, and news. All object information needs to be annotated in a TV program to identify the user selection. However, the effort must be reduced, as it costs too much. The program can be identified as an annotated item, a combination of known base area and spatial relations to the user selection, even though it does not have the exact position. The TV system can semantically interact with the user via this combination. A prototype system, semantic interaction TV, has been implemented to achieve this semantic interaction.
