From newspaper to microblogging: What does it take to find opinions?
نویسندگان
چکیده
We compare the performance of two lexiconbased sentiment systems – SentiStrength (Thelwall et al., 2012) and SO-CAL (Taboada et al., 2011) – on the two genres of newspaper text and tweets. While SentiStrength has been geared specifically toward short social-media text, SO-CAL was built for general, longer text. After the initial comparison, we successively enrich the SO-CAL-based analysis with tweet-specific mechanisms and observe that in some cases, this improves the performance. A qualitative error analysis then identifies classes of typical problems the two systems have with tweets.

متن کاملMistaking the Map for the Territory: What Society Does With Medicine; Comment on “Medicalisation and Overdiagnosis: What Society Does to Medicine”
Van Dijk et al describe how society’s influence on medicine drives both medicalisation and overdiagnosis, and allege that a major political and ethical concern regarding our increasingly interpreting the world through a biomedical lens is that it serves to individualise and depoliticize social problems. I argue that for medicalisation to serve this purpose, it would have to exclude the possibil...

The development and evolution of any system–person, organization–nation depends on how the system succeeds to bridge the gap between what the system knows and what the system does (with the knowledge). We call this the gap between knowing and doing or the knowing-doing gap. If the system does not do what it knows, it will lose out in competition with other systems, its relative performance in...
