Arabica

A Python package for exploratory analysis of text data

Text data is often recorded as a time series with significant variability over time. Some examples of time-series text data include Twitter tweets, product reviews, and newspaper headlines. Arabica provides functions to make the exploratory analysis of such datasets simple.

Arabica provides these methods:

• arabica_freq: calculates unigram, bigram, and trigram frequencies over a period (year, month)

It can apply all or a selected combination of the following cleaning operations:

• Remove digits from the text
• Remove punctuations from the text
• Remove standard list of stopwords

arabica uses clean-text for punctuation cleaning and nltk corpus of stopwords.

Installation

Arabica requires Python 3, NLTK, and clean-text, to execute. To install using pip, use:

pip install arabica

Usage

• Import the library:

from arabica import arabica_freq

• Choose a method:

Arabica returns a dataframe with aggregated unigrams, bigrams, and trigrams frequencies over a period. To remove stopwords, select aggregation period, and choose a specific set of cleaning operations:

def arabica_freq(text: str, # Text
                 time: str, # Time
                 stopwords: str, # Language for stop words
                 punct: bool = False, # Remove all punctuations
                 max_words: int='', # Max number for unigrams, bigrams and trigrams displayed
                 time_freq: str='', # Aggregation period, 'Y'/'M'
                 numbers: bool = False # Remove all digits
) 

Example

import pandas as pd
from arabica import arabica_freq

data = pd.DataFrame({'text': ['The ordering process was very easy & straight forward. They have great customer service and sorted any issues out very quickly.',
                              'So far seems to be the wrong product for me :-/',
                              'Excellent, service, thank you really, really, really much!!!'],
                     'time': ['2013-08-8', '2013-09-8','2014-10-8']})

arabica_freq(text= data['text'],time=data['time'],time_freq='M',max_words=2,stopwords='english', numbers = True, punct=True)
