  • Recently, many users frequently share their opinions on diverse issues using various social media. Therefore, many governments have attempted to establish or improve national policies according to the public opinions captured from the various social media. In this paper, we indicate several limitations of traditional approaches for analyzing public opinions about science and technology and provide an alternative methodology to overcome the limitations. First of all, we distinguish science and technology analysis phase and social issue analysis phase to reflect the fact that public opinion can be formed only when a certain science and technology is applied to a specific social issue. Next, we apply a start list and a stop list successively to acquire clarified and interesting results. Finally, to identify most appropriate documents fitting to a given subject, we develop a new concept of logical filter that consists of not only mere keywords but also a logical relationship among keywords. This study then analyzes the possibilities for the practical use of the proposed methodology thorough its application to discovering core issues and public opinions from 1,700,886 documents comprising SNS, blog, news, and discussion.

  • Objectives: To examine the opinions regarding recovery and assess their will to recover in outpatients with schizophrenia. Methods: Total 98 stable outpatients with schizophrenia were enrolled. To investigate the outpatients' opinions regarding recovery, we asked the subjects to write down the ways they could think they had recovered from their current disease. We classified their answers and chose final 39 statements. Using this questionnaire, they were asked to what extent they agreed with each statement. Moreover, the Recovery Assessment Scale (RAS) was used to measure the subjects' will to recover. Results: Many of the 39 subjects who were surveyed about their opinions on recovery agreed on 11 statements about taking medicine, social life, daily life, social functioning, positivity about life (happiness, hope, confidence, and tranquility), symptoms, occupation, and self-control. The RAS score showed a significant correlation with age (r=-0.26, p<0.01), age at onset (r=0.26, p<0.01), duration of illness (r=-0.52, p<0.01), and number of hospitalization (r=-0.46, p<0.01). Conclusion: This study shows that positivity about life is an important part of the patients' subjective recovery criteria in schizophrenia. Therefore, if clinicians pay more attention to this part of subjective recovery, it would strengthen the patients' will for recovery.

  • In empirical software engineering research, there is an increased use of questionnaires and surveys to collect information from practitioners. Typically, such data is then analyzed based on overall, descriptive statistics. Overall, they consider the whole survey population as a single group with some sampling techniques to extract varieties. In some cases, the population is also partitioned into sub-groups based on some background information. However, this does not reveal opinion diversity properly as similar opinions can exist in different segments of the population, whereas people within the same group might have different opinions. Even though existing approach can capture the general trends there is a risk that the opinions of different sub-groups are lost. The problem becomes more complex in case of longitudinal studies where minority opinions might fade or resolute over time. Survey based longitudinal data may have some potential patterns which can be extracted through a clustering process. It may reveal new information and attract attention to alternative perspectives. We suggest using a data mining approach to finding the diversity among the different groups in longitudinal studies (agile skeptics). In our study, we show that diversity can be revealed and tracked over time with the use of clustering approach, and the minorities have an opportunity to be heard.

  • Opinion Mining summarizes with classifying sensitive opinions of customers in huge online customer reviews for the attributes of products or services by positive and negative opinions. Because the customers represent their interests through subjective opinions as well as objective facts, the existing opinion mining techniques, which can analyze just the sensitive opinions, need to be expanded.. In this paper, We propose the novel entity association network model which expands the existing opinion mining techniques. The entity association model can not only represent positive and negative degree of the sensitive opinions, but also can represent the degree of the associations and relative importances between entities. We designed and implemented the customer reviews analysis system based on the entity association network model. We recognized that the system can represent more abundant information than the existing opinion mining techniques.

Here are some of results of this research; Although apartment residents who have experienced the process of reconstruction have a great desire to participate and a wide range of participation, the proper procedure of participation is not prepared and the contents of reconstruction is not fully understood. And the residents have the different opinions on 'height and mass of apartment' and 'amount of compensation and payment'. Meanwhile, the residents believe that all of them should take part in the participation process and some government interventions are needed. Accordingly, various ways for resident participation in the process of reconstruction are to be provided and new techniques for encouraging public participation are to be sought.
