[new annotation proposal] Sentiment Analysis #16

Closed proycon closed 8 years ago

proycon commented 8 years ago

FoLiA currently has the token annotation subjectivity for limited sentiment analysis or other subjectivity annotation, it is used by the VU-DNC corpus for instance. This, however, is not sufficient for more complex expressions of sentiment. A strong span annotation element is needed. The following proposal is inspired on NAF's opinion layer:

<s>
 <w xml:id="w1"><t>He</t></w>
 <w xml:id="w2"><t>is</t></w>
 <w xml:id="w3"><t>happy</t></w>
 <w xml:id="w4"><t>to</t></w>
 <w xml:id="w5"><t>see</t></w>
 <w xml:id="w6"><t>him</t></w>
 <w xml:id="w7"><t>.</t></w>
 <sentiments>
  <sentiment class="emotion.joy" polarity="positive" strength="moderate">
    <source>
      <wref id="w1" t="he" />
    </source>
    <target>
      <wref id="w6" t="him" />
    </target>
    <hd>
      <wref id="w3" t="happy" />
    </hd>
  </sentiment>
 </sentiments>
</s>

This predefines the following feature subsets, whether they are actually used and the class values they take are defined by the set.

The following span role elements are introduced and used (will be reused in another upcoming proposal as well):
