Install NRC Lexicon from within Jupyter Notebook

 .

1.Upgrade Python version (if needed)

import sys !{sys.executable} -m pip install --upgrade pip

Expected output:

Requirement already satisfied: pip in c:\portable\jupyterlab-portable-3.1.0-3.9\apps\lib\site-packages (21.2.1) Collecting pip Downloading pip-21.2.4-py3-none-any.whl (1.6 MB) Installing collected packages: pip Attempting uninstall: pip Found existing installation: pip 21.2.1 Uninstalling pip-21.2.1: Successfully uninstalled pip-21.2.1 Successfully installed pip-21.2.4

---

2.Install NRC Lexicon

!{sys.executable} -m pip install NRCLex

Expected Output

Collecting NRCLex Downloading NRCLex-3.0.0.tar.gz (396 kB) Collecting textblob Downloading textblob-0.15.3-py2.py3-none-any.whl (636 kB) Collecting nltk>=3.1 Downloading nltk-3.6.3-py3-none-any.whl (1.5 MB) Collecting joblib Downloading joblib-1.0.1-py3-none-any.whl (303 kB) Collecting regex Downloading regex-2021.8.28-cp39-cp39-win_amd64.whl (271 kB) Collecting click Downloading click-8.0.1-py3-none-any.whl (97 kB) Collecting tqdm Downloading tqdm-4.62.3-py2.py3-none-any.whl (76 kB) Requirement already satisfied: colorama in c:\portable\jupyterlab-portable-3.1.0-3.9\apps\lib\site-packages (from click->nltk>=3.1->textblob->NRCLex) (0.4.4) Using legacy 'setup.py install' for NRCLex, since package 'wheel' is not installed. Installing collected packages: tqdm, regex, joblib, click, nltk, textblob, NRCLex Running setup.py install for NRCLex: started Running setup.py install for NRCLex: finished with status 'done' Successfully installed NRCLex-3.0.0 click-8.0.1 joblib-1.0.1 nltk-3.6.3 regex-2021.8.28 textblob-0.15.3 tqdm-4.62.3

---

Note: Even after the installation of NRC Lexicon, MissingCorpusError may occur while running programs. So it is recommended to also install textblob.download_corpora.

3.Install textblob.download_corpora (Recommended)

import sys !{sys.executable} -m textblob.download_corpora

Expected Output

[nltk_data] Downloading package brown to C:\Portable\JupyterLab- [nltk_data] Portable-3.1.0-3.9\apps\nltk_data... [nltk_data] Unzipping corpora\brown.zip. [nltk_data] Downloading package punkt to C:\Portable\JupyterLab- [nltk_data] Portable-3.1.0-3.9\apps\nltk_data... [nltk_data] Unzipping tokenizers\punkt.zip.

Text Processing in Python Text using NLTK and spaCy

  

.

The Internet has connected the world, while Social Media like Facebook, Twitter and Reddit provided the platform for people to express their opinions and feelings toward a topic. Then, the proliferation of smartphones increased the usage of these platforms directly. For instance, there are 96% or 2,240 million Facebook active users who used Facebook by smartphones and tablets [1].

The increment in the usage of Social Media has grown the size of text data, and boost the studies or researches in Natural Language Processing (NLP), for example, Information Retrieval and Sentiment Analysis. Most of the time, the documents or the text files to be analyzed are gigantic and contains a lot of noise, directly used raw texts for analysis is inapplicable. Hence, text processing is essential to provide clean input for modelling and analysis.

Text processing contains two main phases, which are tokenization and normalization [2]. Tokenization is the process of splitting a longer string of text into smaller pieces, or tokens [3]. Normalization referring to convert number to their word equivalent, remove punctuation, convert all text to the same case, remove stopwords, remove noise, lemmatizing and stemming.

Stemming — removing affixes (suffixed, prefixes, infixes, circumfixes), For example, running to run

Lemmatization — capture canonical form based on a word’s lemma. For example, better to good [4]

.

Text Processing with NLTK

1. Tokenization

2. Normalization

a. Removing Stop words

b. Lemmatization

3. Obtain the Cleaned Tokens

Text Processing with spaCy
