Opinion Annotation in GATE

Introduction

The instructions below apply to the current style of opinion annotation performed by the Subjectivity Analysis group at the University of Pittsburgh. For a discussion of the annotation scheme please read the LRE 2005 paper on annotating subjectivity, and this paper for the extension with attitude annotations. The tool that we use for annotation is GATE, which is freely available from Sheffield University. See http://gate.ac.uk/ for more information about GATE.

Annotation Practice

This practice will walk you through a variety of different cases (implicit DSEs and OSEs, implicit sources, etc.) and show how they are annotated in GATE. Download examples-untagged.xml, start GATE according to the instructions above, load examples-untagged.xml into GATE, and work through the examples. The annotations of the first, second, and third snippets that make up the examples-untagged file can be seen by following the links.

For more practice, try annotating one of these articles:

• 21.38.12-11637.unannotated.xml
  
• 17.58.35-21375.unannotated.xml
  

Below are versions of the practice articles that have been annotated. Use these for reference or to check your annotations, if you decided to try your hand at them.

• 21.38.12-11637.attitudes.xml
  
• 17.58.35-21375.attitudes.xml
