Sentiment classification: a lexical similarity based approach for extracting subjectivity in documents

With the growth of social media, document sentiment classification has become an active area of research in this decade. It can be viewed as a special case of topical classification applied only to subjective portions of a document (sources of sentiment). Hence, the key task in document sentiment classification is extracting subjectivity. Existing approaches to extract subjectivity rely heavily on linguistic resources such as sentiment lexicons and complex supervised patterns based on part-of-speech (POS) information. This makes the task of subjective feature extraction complex and resource dependent. In this work, we try to minimize the dependency on linguistic resources in sentiment classification. We propose a simple and statistical methodology called review summary (RSUMM) and use it in combination with well-known feature selection methods to extract subjectivity. Our experimental results on a movie review dataset prove the effectiveness of the proposed methodology.     

Evaluating a monolingual multinational digital library by using usability: An exploratory approach from a developing country

In this paper the authors present a preliminary discussion on some of the results from a survey aimed to explore, describe and explain some of the usability characteristics in digital libraries evaluation in the Mexican context. The study is framed in the evaluation of a multinational and monolingual digital library: the Miguel de Cervantes Virtual Library, from the University of Alicante in Spain. The evaluators were Mexican “expert” users (i.e. Spanish-speaking professional university librarians specialized in electronic reference services) who were asked to carry on an evaluation instrument based on usability criteria as taken from some models in developed countries. Some questions that might be answered with future research are outlined in this paper.

The effect of adolescents' sports clubs participation on self-reported mental and physical conditions and future expectations

Abstract

Sports clubs create conditions for people of all ages to pursue a healthy lifestyle through exercise in sports and attend to constructive pedagogical work which creates much value for society. This study investigates the relationship between adolescents' sports clubs participation and self-reported mental and physical conditions and future expectations. The participants were 10,987 pupils in the final three years of their compulsory education in Iceland (aged 14–16 years). The participants completed questionnaires administered to students in the classroom relating to health and behaviour. The results indicate that participation in sports clubs influences adolescents positively; adolescents who work hard at sport not only believe they are in better mental and physical condition, they also believe they can succeed in other areas such as their studies. Sports clubs promote positive influence on adolescents' mental and physical conditions and their future expectations toward work and happiness. It can be concluded that participation in organised sports clubs affects the participants in a positive way.

山西省太原市3所高中业余田径运动员损伤调查及其分析

多年来,运动损伤一直影响着田径运动员的训练和比赛,使科学系统的训练和比赛难以按计划正常进行,导致一批有前途的运动员过早地离开田径场,严重阻碍了田径运动水平的不断提高。为了避免和减少运动员在训练、比赛中的伤病发生,延长运动员的运动生涯,提高训练质量。本文通过对山西省太原市3所高中业余田径运动员的常见损伤进行了调查统计和分析,并通过问卷调查分析其田径课余训练运动损伤的原因,具体区分男女运动员不同项目、不同层次运动损伤的特点,对其进行总结归纳从而将运动损伤率降低到最低,使我市业余田径运动员预防损伤的意识增强、整体水平提高、运动寿命延长。为该地区教练制定田径业余训练、考学安全预防措施、积极调整学生心理状态,提供依据;使得训练、比赛、考学顺利进行,最终达到提高整个市的运动水平,为我国田径事业的蓬勃发展奠定基础。     

Towards a Cultural Understanding of the Disability and Deaf Experience: A Content Analysis of Introductory Multicultural Education Textbooks

This paper reports the findings of a simple normative content analysis of 11 multicultural education textbooks to determine the extent to which disability and deaf culture are represented. In addition, this study examines multicultural education textbooks to assess the extent to which perspectives of members of the disability and deaf communities are represented in the discourse about disabled and deaf persons. Results indicate that on average less than 1% of the total pages of text reviewed addressed or mentioned disability or deaf culture. Of these, it was found that on average about 6% of the pages addressed disability or deaf culture. In addition, inaccurate information was presented and perspectives were often not informed by a substantial body of literature that has emerged in the field of disability studies. It was found that multicultural education textbooks rely heavily on information about persons with disabilities from Special Education that may not be widely accepted by disabled or deaf persons. A follow-up paper examines the implications of the exclusion of disabled and deaf persons and their perspectives from the discourse about the shared and collective disability and deaf experience in favor of a dominant perspective widely held by the nondisabled professional community. Questions are raised about whether this is consistent with the values and goals of multicultural education and teaching. A rationale and recommendations are proposed for engaging disabled and deaf persons about their shared and collective experience and for promoting cultural competence and proficiency with respect to the disability and Deaf experience in multicultural education.
