So there is the problem of mobility that a Mobile Node (MN) may move from one network to other network, also there is the problem of connectivity. To maintain the connectivity of a established call between two different networks using mobility management we proposed an efficient algorithm which maintain the real time connection as well as preventing the data loss during transition. We experiment our proposed algorithm by using a redundant buffer which store the data in transition mode and vanish the alternate data bits when the connection is establish with the network. The alternate data bit is also send for the same time as the time taken by the redundant buffer to disappear the data. This process saves our data in the transition time.","PeriodicalId":166169,"journal":{"name":"2010 2nd International Conference on Information Technology Convergence and Services","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123611272","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}

Most of inaccurate results are from failing to understand user???s search goal. This paper proposes a method to mine user???s intentions and to build an intention map representing their information needs. It selects intention features from search logs obtained from previous search sessions on a given query and extracts user???s intentions by using clustering and labeling algorithms. The mined user???s intentions on the query are represented in an intention map. For the efficiency analysis of intention maps, we extracted user intentions using 2,600 search log data of a current domestic commercial web search engine. The experimental results using a web search engine with the intention maps show statistically significant improvements in user satisfaction scores.","PeriodicalId":166169,"journal":{"name":"2010 2nd International Conference on Information Technology Convergence and Services","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121979309","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 proposed model acquires lexical entries from a raw corpus by unsupervised learning like human. The model is composed of full-form and morpheme acquisition modules. In the full-from acquisition module, core full-forms are automatically acquired according to the frequency and recency thresholds. In the morpheme acquisition module, a repeatedly occurring substring in different full-forms is chosen as a candidate morpheme. Then, the candidate is corroborated as a morpheme by using the entropy measure of syllables in the string. The experimental results with a Korean corpus of which size is about 16 million full-forms show that the model successively acquires major full-forms and morphemes with the precision of 100% and 99.04%, respectively.","PeriodicalId":166169,"journal":{"name":"2010 2nd International Conference on Information Technology Convergence and Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131197316","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 most practical manner relate to this issue is to use a node wake-up scheduling protocol that some sensor nodes stay active to provide sensing service, while the others are inactive for conserving their energy. Especially, CTC (Connected Target Coverage) problem has been considered as a representative energy-efficiency problem considering connectivity as well as target coverage. In this paper, we propose a new energy consumption model considering overlapped targets and create a new problem, OTCC (Overlapped Target and Connected Coverage) problem of which objective is to maximize the network lifetime based on the new energy consumption model. Also, we present SPT (Shortest Path based on Targets)-Greedy algorithm to solve the problem. Our simulation results show that SPT-Greedy algorithm performs much better than the previous algorithm in terms of the network lifetime.","PeriodicalId":166169,"journal":{"name":"2010 2nd International Conference on Information Technology Convergence and Services","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126589005","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}

But it also leads to the harmful side effects that are creation and uncontrolled distribution of objectionable contents. Especially it is very serious for pornographic contents that are more than about 70% of objectionable contents. The objectionable contents mean the pornographic contents in this paper. Most of the related studies are focused on image-based approaches and there are few studies based on audio-based approaches. In this paper, we try to classify objectionable contents based on various audio signal features. The audio signal features used in this paper are perceptual features that are spectral properties, MFCC based feature set and TDMFCC based feature set. For the reasonable results, we define the audio-based objectionable contents model and then construct dataset according to the defined model. For training and classifying dataset of two classes, objectionable and nonobjectionable class, SVM classifier is used. TDMFCC based feature set has a good performance of accurate rate with SVM classifier, about 95%, and the results show that it is very effective to detect and classify the objectionable contents based on audio features.","PeriodicalId":166169,"journal":{"name":"2010 2nd International Conference on Information Technology Convergence and Services","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124844421","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}
