Sentiment analysis is used to find sentiment of author from a text, like tweets, posts or blog. Lets do this in Python:
1. Python is already installed on Linux distributions and can be install on windows using installer http://www.python.org/download/releases/2.7.6/
2. Install easy install and pip package manager:
Download python script from https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py and execute using "python <path/to/ez_setup.py>"
Install pip using "
Python script to do sentiment analysis:
This Python script,
Corrects spelling or can suggest correction (check other methods for that).
Translates text using Google translate.

3. Install TextBlob using "
pip install -U textblob"Python script to do sentiment analysis:
from textblob import TextBlob
class TextTool:
def
analyseText(self, text, sourceLang='en',
translateTo='en', spellCorrection=False):
blob =
TextBlob(text)
if spellCorrection: #correct spelling
correctedTxt = blob.correct()
if
translateTo!=None and sourceLang!=translateTo: #translate text
if
sourceLang!=None:
translatedTxt = blob.translate(sourceLang, translateTo)
else:
translatedTxt = blob.translate(to=translateTo)
#return sentiment score, 0-10 (negative to positive, 5 as neutral)
return
blob.sentiment, correctedTxt.__str__() if spellCorrection else None,
translatedTxt.__str__() if translateTo!=None and sourceLang!=translateTo else
None
textTool = TextTool()
analysis = textTool.analyseText(“Its great to see this again
… wow”)
