How do I learn spaCy?

First, we import the spaCy matcher. After that, we initialize the matcher object with the default spaCy vocabulary. Then, we pass the input in an NLP object as usual. In the next step, we define the rule/pattern for what we want to extract from the text.Mar 9, 2020

What is a knowledge graph in NLP?

A knowledge graph is a way of storing data that resulted from an information extraction task. Many basic implementations of knowledge graphs make use of a concept we call triple, that is a set of three items(a subject, a predicate and an object) that we can use to store information about something.

How do you load a spaCy model?

To load a pipeline from a data directory, you can use spacy. load() with the local path. This will look for a config. cfg in the directory and use the lang and pipeline settings to initialize a Language class with a processing pipeline and load in the model data.

How do I add a custom entity to spaCy?

EntityRuler() allows you to create your own entities to add to a spaCy pipeline. You start by creating an instance of EntityRuler() and passing it the current pipeline, nlp . You can then call add_patterns() on the instance and pass it a dictionary of the text pattern you'd like to label with an entity.
