理解 semcor 语料库结构 h

Question

我正在学习NLP。我目前正在玩词义消歧。我计划使用 semcor 语料库作为训练数据，但我无法理解 xml 结构。我尝试谷歌搜索，但没有得到任何描述 semcor 内容结构的资源。

<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>

• 我假设 wnsn 是“词义”。正确吗？
• 属性 lexsn 是什么意思？它如何映射到wordnet？
• 属性 pn 指的是什么？ （第三行）
• rdf属性是如何分配的？ （再次第三行）
• 一般来说，可能的属性是什么？
