Hey folks! Today in this tutorial, we will be understanding what Dependency Parsing is and how to implement the same using the Python programming language.<\/p>\n\n\n\n

\n\n\n\n

What is Dependency Parsing?<\/h2>\n\n\n\n

The technique of assessing the grammatical structure of a sentence based on the dependencies between the words in a sentence is known as Dependency Parsing.<\/em><\/strong><\/p>\n\n\n\n

Various tags in dependency parsing describe the relationship between two words in a sentence. These are the dependencies tags<\/em><\/strong>.<\/p>\n\n\n\n

Why is Dependency Parsing needed?<\/h2>\n\n\n\n

Dependency parsing allows us to construct a parsing tree using tags to determine the relationship between words in a sentence rather than using any Grammar rule as in syntactic parsing, which provides a lot of flexibility even when the order of words changes.<\/p>\n\n\n\n

\n\n\n\n

Implementing Dependency Parsing in Python <\/h2>\n\n\n\n

For implementing Dependency Parsing, we would make use of the spaCy<\/code> module in Python. So, first of all, we import the same into our program.<\/p>\n\n\n

\nimport spacy\nfrom spacy import displacy\n<\/pre><\/div>\n\n\n
Now let’s take some random sentences on which we want to perform Dependency Parsing.<\/p>\n\n\n
\ntext1 = 'It took me more than two hours to translate a few pages of English.'\ntext2 = 'The old rusted farm equipment surrounded the house predicting its demise.'\ntext3 = 'I am a great listener, really good with empathy vs sympathy and all that, but I hate people.'\ntext4 = 'The ants enjoyed the barbecue more than the family.'\n<\/pre><\/div>\n\n\n
Next, we use spacy.load<\/code> function which will help to construct a language object and load in the model data and weights, and return it.<\/p>\n\n\n
\nnlp=spacy.load('en_core_web_sm')\n<\/pre><\/div>\n\n\n
Finally, we will display the dependency parsing output for the texts mentioned in the previous code snippet.<\/p>\n\n\n
\ndisplacy.render(nlp(text1),jupyter=True)\n<\/pre><\/div>\n\n\n

Conclusion<\/h2>\n\n\n\n
Congratulations! You just learned how to build a Dependency Parsing chart for sentences using NLP. Hope you enjoyed it! 😇<\/p>\n\n\n\n
