I'm learning NLP. I currently playing with Word
Sense Disambiguation. I'm planning to use the semcor corpus as training data but I have trouble understanding the xml structure. I tried googling but did not get any resource describing the content structure
of semcor.
<s snum="1">
<wf cmd="ignore" pos="DT">The</wf>
<wf cmd="done" lemma="group" lexsn="1:03:00::" pn="group" pos="NNP" rdf="group" wnsn="1">Fulton_County_Grand_Jury</wf>
<wf cmd="done" lemma="say" lexsn="2:32:00::" pos="VB" wnsn="1">said</wf>
<wf cmd="done" lemma="friday" lexsn="1:28:00::" pos="NN" wnsn="1">Friday</wf>
<wf cmd="ignore" pos="DT">an</wf>
<wf cmd="done" lemma="investigation" lexsn="1:09:00::" pos="NN" wnsn="1">investigation</wf>
<wf cmd="ignore" pos="IN">of</wf>
<wf cmd="done" lemma="atlanta" lexsn="1:15:00::" pos="NN" wnsn="1">Atlanta</wf>
<wf cmd="ignore" pos="POS">'s</wf>
<wf cmd="done" lemma="recent" lexsn="5:00:00:past:00" pos="JJ" wnsn="2">recent</wf>
<wf cmd="done" lemma="primary_election" lexsn="1:04:00::" pos="NN" wnsn="1">primary_election</wf>
<wf cmd="done" lemma="produce" lexsn="2:39:01::" pos="VB" wnsn="4">produced</wf>
<punc>``</punc>
<wf cmd="ignore" pos="DT">no</wf>
<wf cmd="done" lemma="evidence" lexsn="1:09:00::" pos="NN" wnsn="1">evidence</wf>
<punc>''</punc>
<wf cmd="ignore" pos="IN">that</wf>
<wf cmd="ignore" pos="DT">any</wf>
<wf cmd="done" lemma="irregularity" lexsn="1:04:00::" pos="NN" wnsn="1">irregularities</wf>
<wf cmd="done" lemma="take_place" lexsn="2:30:00::" pos="VB" wnsn="1">took_place</wf>
<punc>.</punc>

I'm assuming wnsn is 'word
sense'. Is it correct?
What does the attribute lexsn mean? How does it map to wordnet?
What does the attribute pn refer to? (third line)
How is the rdf attribute assigned? (again third line)
In general, what are the possible attributes?
