This study aims to identify and categorize the characteristics of user-generated content to obtain a profound understanding on the user data, and actively utilize the data in extracting user values. Based on literature review, characteristics of online reviews and photos on Social Network Services (SNS) were investigated to evaluate five categories for online reviews (interactive, imprecise, cultural,...
This study aims to extract the most relevant set consisted of affective variables to the level of user satisfaction on engine sounds using classification algorithm. The affective variables for engine sounds were defined by three axes, and two classification algorithms were used to determine the prediction accuracy for those affective axes. The study was consisted of three phases: 1) extracting sets...
This study introduces systematic review of literatures on human vision. Both content analysis and network analysis are used to quantitatively analyze recent trends in human vision research. Three terms, ‘visual search’, ‘eye movement’ and ‘eye track’, were selected as the central keywords characterizing the research field. Seven sub-categories of research keywords were selected and analyzed in content...
Ar ion beam etching was carried out on NiFe(6)/Cu(1.5)/NiFe(4)/IrMn(20) multilayer spin-valve structure with three different beam voltages in order to optimize the effective beam voltage for patterned Planar Hall device fabrication. VSM characterizations were done on the multilayer structure before and after etching for verification of necessary exchange bias and influence of etching. The multilayer...
