A lightweight model and less inquiry users for true activities, are necessary for deploying the activity recognition on a mobile platform for identifying activities based on new sensory data in real time. In this paper, we propose a new smartphone-based activity recognition framework for evolving sensory data stream called ISAR. It stands for Impersonal Smartphone-based Activity Recognition. ISAR model is built using annotated sensory data from a panel of user as training data and are applied to the new users. Our new model is an offline and online phase. In offline phase, we propose a new method for finding the threshold value which used to distinguish between dormant activities and energetic activities. Only a set of the energetic activities are used to build a light-weight classifier model. In online phase, we introduce the recognition technique of unannotated streaming sensory data with different activities. The experimental results using real human activity recognition data have conducted and compared with STAR model in terms of the accuracy and time complexity. Our results indicates that ISAR model can perform dramatically better than STAR model. Moreover, ISAR can utilize better than STAR model in real situation, especially across different users and without inquiry users.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125369716","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 goal is to publish linked data amongst local governments which allows discovering, accessing and encouraging interoperability. In order to achieve efficient interoperability of information systems, linked data play an important role in relating data. Linked data use semantic web technologies to publish structured data on the web and set links between data. Structure data are encoded as RDF. Furthermore, the data model supports integration of data sources by a linking semantic vocabulary, which is an effective way of exchanging data on the web. We propose a new framework for Thai local government with linked data technology to relate data that was not previously linked to enable exposing, sharing, and connecting pieces of data, information, and knowledge on the semantic web using URLs, RDF, data model and ontology.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126346238","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}

As the prices of crushed stone depend on their types, the automated system that can examine their type is needed to avoid human mistakes. This study aims to propose a novel method for classifying 5 different classes of crushed-stone images in the dump-body of a truck. Remarkably, 4 classes are defined according to 4 types of crushed stone and the other class is the empty dump-body of a truck. We create a crushed-stone predictor called CSDeep based on a convolution neural network (CNN) and the generic texture-features such as Gabor wavelet, Haralick and Laws. A CNN is a backpropagation neural network with an effective image processing tool, i.e., convolutions. The generic texture features are used to provide additional information that is missed by CNN. The set of 2,500 and 500 images equally sampled from each class are used as training and test data, respectively. The optimal set of generic texture features are chosen by an inheritable biobjective combinatorial genetic algorithm. The proposed CSDeep achieves 89.00% of test accuracy. To the best of our knowledge, CSDeep is the first predictor for crushed-stone images taken by a digital camera. The results show that the combination of generic texture-features and CNN is suggested to enhance the performance of a deep learning model.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134387096","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}

This proposed work is developed based on a combination between a text classifier and word centrality measures. Herein, the item's feedback means comments written by customers to the purchased items, which are classified into positive or negative comments. In this work, the suitable text classifier is selected from four major types of classification: Rule-based, Tree structure-based, Probability-based, and Learning-based, which are Conjunctive Rule, Random Forest, Bayesian Logistic Regression, and Support Vector Machine, respectively. In this work, the classifiers are used for identifying the feedbacks in the probability distribution value [0, 1]. On the other hand, items' feedbacks are also represented by a graph, which is presenting a relationship among words. As well as, centrality measures are applied to determine each contained word centrality, and finalize to a probability centrality in [0, 1]. Both probability distribution and probability centrality, here, are applied to classify the item's feedback to positive or negative comments. The simulation results showed that the proposed classification method was efficient to classify three benchmark datasets, compared to other existing approaches with an average of classification accuracy 80.9%.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129401978","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}

SHS is an integration of home appliances together with sensors to get automatic operations of heating, lighting, air conditioning, home security, health care systems, etc. Moreover, SHS allows homeowner to monitor and perform appliances functions remotely at any instant time via the Internet. Due to the widespread availability and proliferation of the SHS, attackers can impersonate as a homeowner to steal important data (e.g., vital signs) for doing extortion and life threatening. Therefore, in this paper, we present an approach of private Blockchain implementation for SHS to cope of its privacy and security issues. We review Ethereum Blockchain packages for SHS according to its smart contract features for handling access control policy, data storage and data flow management.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122816","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}

Method: Eighteen patients with stroke were enrolled in the Rehabilitation Medicine Department, the Third Affiliated Hospital of Sun Yat-sen University from December 2016 to August 2017. The patients were divided into observation group and control group by random number table. Both groups were trained in speech function. The observation group received regular speech training for 20 minutes per day, Virtual Reality (VR) training for 20 minutes per day; the control group was given conventional speech training 40 minutes per day but the same training content with the observation group. And both groups of patients were treated for 5 days per week lasting for 4 weeks. CRRCAE was used to evaluate the language ability before and after treatment. The Boston Diagnostic Aphasia Examination, BDAE was used to assess the severity of aphasia. Bucco-facial-apraxia and speech apraxia Methods were used to assess the patient's state of bucco facial function and speech function. Result: There was no significant difference (P > 0.5) between the situations of two groups in general data, bucco-facial-apraxia and speech apraxia. Before treatment, the difference in CRRCAE and BDAE between the two groups is also not so big(P > 0.05). After 4 weeks of treatment, the severity of aphasia was improved in both groups (P < 0.05). Except computing ability, listening comprehension, repetition, expression, readout, reading, transcription, depiction and dictation were all improved (P < 0.01). And in noun repetition(P = 0.03), sentence repetition (P = 0.01), noun expression(P < 0.01), verb expression (P = 0.02), sentence expression (P < 0.01), comic expression (P = 0.01), enumeration (P = 0.03), verb readout(P = 0.04), verb reading(P < 0.01), sentence reading (P = 0.04), noun transcription (P = 0.02), sentence transcription (P = 0.048), verb depiction (P = 0.01) and so on, language ability of the observation group is significantly better than the control group. Conclusion: Virtual reality technology combined with speech function training can improve the language ability of patients with Broca Aphasia, and its improvement is better than the simple speech function training.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134456721","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}

Although many patients regain most reach and grasp capabilities in their upper extremity function, recovery of the pinch skill remains incomplete for the majority of patients. In this study, an innovative VR-based pinch skill training and strengthening system using haptics simulation was developed for the long-term recovery of upper extremity motor function post stroke. Two subject tests were conducted. The first was a healthy subject test conducted with 30 participants to verify the system design and functionality, specifically emphasizing difficulty levels and behavior phases. The second was a pilot test conducted on two stroke patients to examine the feasibility and therapeutic effects of the proposed system. Upon completion of the pilot test, the results of clinical assessment showed that both participants were improved. Using synchronized kinematic and kinetic data, the participants' behavior time-history was reconstructed for behavior interpretation and motor activity analysis. Finally, user acceptance of the technology was high, indicating that the participants intended to continue using the proposed system for rehabilitation.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"51 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134536498","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}

This kind of skill is accepted as an essential requirement of job recruitment. In this paper, we attempt to primarily analyze the results of English tests and student data by using data mining approaches in order to explore determinants of the results of English exit exams. The research applied multiple data mining approaches namely Naïve Bayes, Bayesian network (Bayes net), decision tree (C4.5) and SVM, to the dataset of graduating students in 2015. By comparing their accuracy, C4.5 outperformed other approaches in predicting the results of English exit exam. The analysis also indicates that “the results of English placement test” was the strongest predictor of the results of English exit exam. Therefore, the results of English placement test were analyzed further against the results of English exit exam by using the linear regression. The main implication of this research is that the university should focus more significantly on students who fail the English placement test and the tests can be arranged more frequently. The future work is needed to construct the C4.5 predictive model for further prediction of the exit exam.","PeriodicalId":405827,"journal":{"name":"2017 2nd International Conference on Information Technology (INCIT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114186578","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}
