However for certain data mining tasks like finding potential causes of a disease or side-effects of a drug, where missing a small piece of information can have grave consequences, the coverage of automatically acquired knowledge bases is often insufficient. This paper explores the use of automatic hypothesis generation for expanding a knowledge base of semantic relations, using distributional word similarities obtained from a large Web corpus. If successful, such a method can drastically improve the coverage of automatically acquired semantic relations, at the expense of a slight reduction in accuracy. We show that large scale similarity-based relation expansion works quite well for this purpose. Using a 100 million Japanese Web page corpus as input, we could generate a substantial amount of new semantic relations that were not found in the input corpus but whose validity was confirmed in a much larger Web corpus, i.e., by using a commercial Web search engine.","PeriodicalId":108217,"journal":{"name":"2010 4th International Universal Communication Symposium","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123066856","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}

Nowadays, with the development of motion capture technology, motion capture data plays an important role in the kinetic analysis of human motion. An interesting problem is whether BSPs can be estimated using the motion capture data. It is well known that the motions of human body should obey Newton's laws of mechanics, which means that human BSPs and motion data should satisfy the motion equation. Then we build an optimization model according to this principle where the objective function measures the degree of mismatch between motion data, human BSPs and Newton's laws of mechanics. By solving this optimization model, we can estimate the human BSPs. To deal with this optimization, we adopt three strategies: variables block, adjustment on constraints and stochastic local search. This method has two advantages. First, given motion capture data, BSPs can be estimated directly without carrying out additional measurements, such as CT imaging. Second, BSPs and motion capture data can be analyzed together. Simulation experimental results show that the errors of mass, centroid and moment of inertia can be controlled within 10%, 5% and 15% respectively.","PeriodicalId":108217,"journal":{"name":"2010 4th International Universal Communication Symposium","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126603854","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}

It utilizes sound source positions and original source signals as features. On the other hand, sound source orientations (such as speaker's orientation) have been neglected, though they are necessary for high-performance URC. In this paper, we propose a 3D sound field recording and reproducing system that includes sound source orientation. For the recording part, we applied and evaluated a sound source orientation estimation method based on orientation-extended beamforming. This method requires transfer functions for all possible source positions and orientations, which should be either measured or calculated. Measured transfer functions have high accuracy because all characteristics, such as reverberations and diffractions, are taken into account. Calculated transfer functions are obtained for any environment without measurements. We performed experiments to evaluate the orientation estimation method using transfer functions obtained by both practical measurements and calculations using acoustic simulation based on wave theory. The experimental results show that our estimation method has sufficient capability using both measured and calculated transfer functions. For the reproducing part, we evaluated impulse responses versus sound source orientation. The evaluation results revealed significant differences in both objective and subjective scores. This proves that our system achieves higher performance than conventional ones that do not utilize orientation features.","PeriodicalId":108217,"journal":{"name":"2010 4th International Universal Communication Symposium","volume":"437 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124253331","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}
