As the development of hardware and software technology, fast increasing of peers or services has issued critical problems for the popularity of SOA. One is system scalability and robustness, and the other one is service location validation. In this paper, we introduce-SOBEX -a web service search engine which designs a distributed indexing structure SIKA, and proposes proactive web services reuse mechanism by introducing service context model SPOT. SIKA is a community-oriented virtual hierarchical distributed indexing structure based on classic Chord algorithm. Though it groups nodes into interest-based communities, it is completely distributed and without central management. Then it promises system search efficiency together with scalability and robustness. The growing number of web services available with an organization and on the web raises new problem: locating the desired web services. Generally keyword-based search has meet with high recall and low precision. In order to improve search efficiency, SOBEX proposes to qualify services using service usage context model, which tries to reduce the concept understanding gap between human and computer by proactively assigning the services with their own story background. On the other hand, besides traditional keyword-based methods, it introduces context-based queries to improve service reusability.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125536447","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}

In Japanese sign language (JSL), previous studies have suggested that emphasis and emotion cause changes in hand movements. However, the relationship between emphasis and emotion and the signing speed has not been researched enough. In this study, we analyzed the hand movement variation in relation to the signing speed. First, we recorded 20 signed sentences at three speeds (fast, normal, and slow) using a digital video recorder and a 3D position sensor. Second, we segmented sentences into three types of components (sign words, transitions, and pauses). In our previous study, we analyzed hand movement variations of sign words in relation to the signing speed. In this study, we analyzed transitions between adjacent sign words by a method similar to that in the previous study. As a result, sign words and transitions showed a similar tendency, and we found that the variation in signing speed mainly caused changes in the distance hands moved. Furthermore, we compared transitions with sign words and found that transitions were slower than sign words.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129852521","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 STEs were extracted by using a series of constant bandwidth band-pass filters with Hilbert transform followed by a low-pass filtering. In the normalization, both the modulation spectrum (MS) of the subband temporal envelopes of the clean and reverberated speech are normalized to a reference MS calculated from a clean speech data set. Based on the normalized subband MS, the inverse Fourier transform was used to restore the subband temporal envelopes. We tested the proposed method on speech recognition in a reverberant room with different speaker to microphone distance (SMD). For comparison, the recognition performance of using the traditional Mel-cepstral coefficients with mean and variance normalization were used as the baseline. Experimental results showed that, by averaging the SMDs from 50 cm to 400 cm, there was a 44.96% relative improvement by only using subband temporal envelope processing, and further a 15.68% relative improvement by using the normalization on the subband modulation spectrum. Totally, there was about a 53.59% relative improvement, which was better than those of using other temporal filtering and normalization methods.","PeriodicalId":103128,"journal":{"name":"Proceedings of the 3rd International Universal Communication Symposium","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134549378","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}
