Fuzzy inferences are powerful denotational mathematical means for rigorously dealing with degrees of matters, uncertainties, and vague semantics of linguistic variables, as well as for precisely reasoning the semantics of fuzzy causalities. This paper presents a denotational mathematical framework of a set of mathematical structures of fuzzy inferences encompassing deductive, inductive, abductive, and analogical inferences. Each of the fuzzy inference processes is formally modeled and illustrated with real-world examples and cases of applications. The formalization of fuzzy inferences and methodologies enables machines to mimic complex human reasoning mechanisms in cognitive informatics, soft computing, and computational intelligence.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129677428","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 purpose of this paper was to study the effectiveness of Mel frequency cepstral coefficients (MFCCs) in capturing the overall mental state of a patient through the analysis of their various vocal emotions displayed during 20 minutes of problem-solving interaction sessions. We also propose both gender based and gender independent clinical depression models using Gaussian Mixture models. Experiments on 139 adolescents subject corpus indicates that incorporation of both first and second time derivatives of MFCCs can improve the overall classification accuracy by 3%. Gender differences proved to be a factor in improving clinical depressed subject detection, where gender based models outperformed the gender independent models by 8%.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129826699","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}

Formal Concept Analysis(FCA) classifies data based on the ordinary set into concept units which consists of objects and attributes that those objects have commonly. However, FCA is insufficient to process and analyze vague data, such as rough and fuzzy data. In this paper, we propose a new FCA-based approach for rough clustering in order to discovery implicit knowledge from given vague fuzzy datasets. Moreover, we show some experiments that demonstrate how our approach can be applied on web mining. Our research results would be helpful for clustering and classifying the vague web data, in particular when dealing web resources with the uncertainty.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127996181","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}

Ninety-two participants were assessed with the acupuncture belief scale (ABS). They rated the valence, expected pain, and fear to three kinds of needle images, including acupuncture, syringe, and sewing needle. They were randomly divided and asked to rate the feasibility of acupuncture-related newspaper headline including either positive (positive group; n = 51) or negative (negative group, n = 41) articles. There was a significant positive correlation between the ABS and the valence for acupuncture needle (r = 0.317, p ≪ 0.01), whereas a significant negative correlation between the ABS and the expected pain (r = −0.248, p ≪ 0.05) and the fear (r = −0.302, p ≪ 0.01) for acupuncture needle, but not other needles. Participants with higher expectancy towards acupuncture rated higher feasibility in response to the positive articles (r=0.499, p≪0.001), whereas lower feasibility in response to the negative articles (r=0.338, p≪0.05). These results indicate that higher expectancy toward acupuncture exhibit more valenced, less painful and fearful responses to the acupuncture needle. Our findings also suggest that information processing regarding health information might be influenced by the pre-occupied belief and expectancy towards medical treatment.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"35 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132351365","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}

Despite this strong relationship, inspection time has had only limited success in expanding our knowledge regarding the nature of intelligence, which can be attributed to a lack of understanding of the neurophysiology underlying IT. In the present study we present a hypothesis in which participants' ITs are determined by their brain's ability to adapt its neural functioning based on experience. This ability is often referred to as neural plasticity. To test this hypothesis, we related participants' ITs to a series of neural plasticity measures identified during a spatial learning task and a reinforcement learning task. In both tasks a significant correlation was found; however, the correlations found were in opposing directions. A subsequent analysis of the tasks revealed a potentially significant relationship between participants' learning ability and their focus of attention. This led us to the conclusion that IT may be determined by participants' neural plasticity through a measure known as neural adaptability, which relates participant experience, learning, and attention.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127355790","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}

Every user on the Internet is able to own his or her blog space as a platform to publish personal thoughts, ideas, comments or works. Information can thus be propagated and shared in a much easier way and this has led to the development and evolution of user communities in the blogosphere. In this work, the phenomenon of information diffusion is studied through the observation of evolving social relationships among bloggers. Specifically, it is noted that a social network can be formed with bloggers and corresponding subscription relationships. Moreover, the subscription of a blogger to another blog site may reflect that the distance among relevant bloggers is shortened due to information diffusion. Consequently, we devise in this work a new data mining capability, i.e., the shortcut patterns, and a proper approach to identify such patterns. Empirical studies show that the proposed scheme is feasible in various applications, including viral marketing and personalized recommendation.","PeriodicalId":420853,"journal":{"name":"2009 8th IEEE International Conference on Cognitive Informatics","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114322384","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}
