SPACY CLEAN TEXT CODE

Significantly, you can create new operations on these objects as well as extend a class with new attributes (adding to the spaCyВ pipeline)

DocВ class has several useful attributes and methods.spaCyВ transforms text into document objects, vocabulary objects, word- token objects, and other useful objects resulting from parsing the text.spaCyВ comes with pre-trained statistical models and word vectors.spaCyВ has 138 public repository implementationsВ on GitHub.explosion /spaCyВ has 16,900 stars on Github ().spacyВ is available for operating systems MS Windows, macOS,В and Ubuntu.

spacyВ is the fastest package, we know of, forВ NLPВ operations.

Because of theВ Cython,В parts ofВ spaCyВ are faster than if implemented in Python

spaCyВ is anВ NLPВ library implemented both inВ PythonВ andВ Cython.

spaCyВ is aВ goodВ choice if you want to go into production with yourВ NLPВ application.

If you use a selection from spaCy, Hugging Face, fast.aiВ , andВ GPT-3В , then you are performingВ SOTAВ (state-of-the-art)В researchВ of differentВ NLPВ models (my opinion at the time of writing this blog).

spaCyВ is a moderateВ choice if you want to researchВ different NLPВ models with a corpus whose length is greater than a million words.

Regex support is part of the standard libraryВ of JavaВ and Python, and is built into the syntax of others, including Perl and ECMAScriptВ (JavaScript) spaCy Regex, in various forms, has been around for over 50 years. The use of regexВ is pervasive throughout our text-preprocessing code.

NLTKВ is a badВ choice if you want to go into production with your NLPВ application.

NLTKВ is a goodВ choice if you want to explore different NLPВ with a corpus whose length is less than a million words.

All the tools take strings as input and return strings or lists of strings as output. That is why we refer to them as вЂњfactoids.вЂќ NLTK Note: The following вЂњfactoidsвЂќ may be biased. The following are some of the вЂњfactoidsвЂќ we used in our decision process. We use spaCy, textacy, Hugging FaceВ transformers, and regex in most of ourВ NLPВ production applications. In follow-on blogs, we will cover different deep learning language models and Transformers (Steps 2-n) fed by the corpus token/lemma stream. The most frequent example is normalization by transforming all characters to lowercase. Normalization of the corpus is transforming the text into a common form. WeвЂ™ll cover replacement and removal of the noise. For example, e-mail may or may not be removed if it is a text classification task or a text redaction task. Noise removal deletes or transforms things in the text that degrade theВ NLPВ task model. The rest of this article is devoted to noise removal text and normalization of text into tokens/lemmas (Step 1: text pre-processing).

A corpus is an input (text preprocessed into a sequence of tokens) intoВ NLPВ models for training or prediction.

A goal is rarely achieved until the introduction of the transformerВ .

The goal is to transform the text into a corpus that any NLP model can use. We clean (noise removal) and then normalize the text. We segment NLPВ into two major steps (for the convenience of this article): I report benchmarks forВ NLPВ text pre-processing tasks

I detail the production-levelВ NLPВ preprocessing text tasks with python code and packages.

I discuss packages we use for production-levelВ NLP.

In production-grade Natural Language Processing (NLP), what is covered in this blog is that fast text pre-processing (noise cleaning and normalization) is critical. The feeding of that sequence of tokens into a Natural Language model to accomplish a specific model task is not covered here. We stop at feeding the sequence of tokens into a Natural Language model. It covers text preprocessing up to producing tokens and lemmas from the text.

Instead, it assumes you are familiar with noise reduction and normalization of text. This blog is not an article introducing you to Natural Language Processing. New deep learning language models (transformers) have caused explosive growth in industry applicationsВ . Estimates state that 70%вЂ“85% of the worldвЂ™s data is text (unstructured data)В .
