मैं एनएलपी/पीओएस-टैगर प्रोजेक्ट के लिए रिएक्ट जेएस में एक पार्सर पेड़ बनाने की कोशिश कर रहा हूं। मैंने पाया कि गोजे एक शांत पार्सर पेड़ GoJs-parser-tree प्रदान करता है, लेकिन मुझे प्रतिक्रिया जेएस कार्यान्वयन के लिए दस्तावेज़ीकरण नहीं मिला। मैं कुछ उदाहरण की कोशिश की, लेकिन मैं इसका इस्तेमाल नहीं कर सकता है heres मेरी कोड है कि मैं इसका इस्तेमाल करने में प्रतिक्रियाReactJs में GoJs का उपयोग

<p>A <em>parse tree</em> is an ordered, rooted tree representing the structure of a sentence, broken down to parts-of-speech.</p>
<p>
This diagram uses a custom <a>TreeLayout</a> called <b>FlatTreeLayout</b> that places all leaf nodes at the same Y position.
It also makes use of a <b>TreeExpanderButton</b> on the node template. See the <a href="../intro/buttons.html">Intro page on Buttons</a> for more GoJS button information.
</p>
<p>
The abbreviations used in this diagram are:
<ul>
<li><b>NP</b>, a noun phrase</li>
<li><b>VP</b>, a verb phrase</li>
<li><b>PP</b>, a prepositional phrase</li>
<li><b>DT</b>, a determiner</li>
<li><b>JJ</b>, an adjective</li>
<li><b>NN</b>, a common noun</li>
<li><b>VBZ</b>, a third person singular present verb</li>
<li><b>VBN</b>, a past participle verb</li>
