No full textUnderstanding Sentiment Words and Truthful Opinions from Academic Feedbacks
No full textOnline feedbacks have become increasingly popular means of gathering students’ reviews and judging the quality of various services offered by an institution, such as courses, teaching, evaluation, infrastructure and many others. Generally, academic feedbacks include values through numerical ratings and free text comments. In this paper, we employ a natural language-based approach to extract features of feedbacks, capture sentiment words from those feedbacks and build opinion vocabulary from the corpus of academic feedbacks. Also, we focus on studying student behaviour while reporting their feedbacks. Particularly, we investigate the reliability of quantitative features through numerical ratings that students offer, by estimating the linguistic evidence from the free text in the feedback

No full textFlax:sustainability is the new luxury
No full textFlax: increasing its value for society’ was the challenge posed by cross-border researchers funded by the European Union INTERREG IV A France (Channel)—England call, as the ancient flax fiber had seen a dramatic decline in consumer appeal and market share. The resulting collaboration value 2.9 million Euros, author was CO-I, ProjectFlax, delivered new innovations where novel applications in sustainable materials for human and environmental wellbeing produced premium products from an unexpected plant source. Could value in future be defined and measured not just by the aesthetics of the artefact, but by assessing the true value of materials using a holistic narrative in relation to process, the philosophy and sustainability of the application? This assessment is, we argue, new luxury. The purpose of this chapter is to show that flax was an unexpected source of innovation for societal advantage, appealing to consumers who desired a deeper material meaning and product differentiation—characteristics afforded by traditional expensive luxury brands. The collaboration between design, science, technology, engineering, mathematics and business (D-STEM-B) combined discipline methodologies, which resulted in new thinking and problem solving. Case study, desk-based, laboratory, practice-led, field study, quantitative, qualitative, narrative and observational methods were explored by 20 national and international, commercial and institutional flax researchers. The findings included improved agricultural and industrial production methods, composites, foodstuffs, biodegradable packaging, bio materials, fashion and interior product prototypes. The research has contributed to a knowledge transfer toolbox between D-STEM-B partners and advanced transdisciplinary working methods, which resulted in further successful funding applications and new market opportunities for flax
