Annotating Topics of Opinions
Veselin Stoyanov, Claire Cardie · 2008
Fine-grained subjectivity analysis has been the subject of much recent research attention.As a result, the field has gained a number of working definitions, technical approaches and manually annotated corpora that cover many facets of subjectivity.Little work has been done, however, on one aspect of fine-grained opinions -the specification and identification of opinion topics.In particular, due to the difficulty of manual opinion topic annotation, no general-purpose opinion corpus with information about topics of fine-grained opinions currently exists.In this paper, we propose a methodology for the manual annotation of opinion topics and use it to annotate a portion of an existing general-purpose opinion corpus with opinion topic information.Inter-annotator agreement results according to a number of metrics suggest that the annotations are reliable.
