How Does Python Analyze Twitter Data?
You’ve probably wondered how to extract sentiment from Twitter data. You can use the Python library TextBlob to do so. This library is built over the NLTK library and aims to remove links and special characters from tweets. Once the tweets have been tokenized, they can be analyzed by classifying the sentiment. One example of a Python application that uses this library is Movies Reviews. The TextBlob library can extract positive features from negative tweets.
Sentiment analysis is a process of ‘computationally’ determining whether a piece of writing is positive, negative or neutral
The general purpose of sentiment analysis is to identify the sentiment of a piece of writing, whether it is positive or negative. Many of the tasks that fall under the category of sentiment analysis include categorization and polarity determination. To see also : How to Find Out Who Blocked Me on Twitter. Traditionally, these tasks are positive and negative. Xia et al. (2015) studied intra-opinion aspects of sentiment analysis to determine the impact of context on sentiment classification accuracy.
A common misconception about sentiment analysis is that it cannot be used to predict human emotions, but can only be used to determine the emotion of a piece of writing. However, this approach is not without merit. A large amount of labeled data is required for training. A large amount of data is needed for training a machine learning model to accurately determine the sentiment of a piece of writing.
TextBlob is a python library for processing textual data
You can use the TextBlob library for Python to process textual data. The library provides an easy-to-use API for common natural language processing tasks, including noun-phrase extraction, sentiment analysis, classifying and translating text.

As a Python library for text processing, TextBlob is very versatile and supports complex analysis and operations. Sentiment analysis, also known as opinion mining, uses computational linguistics and natural language processing to determine the polarity and subjectivity of text. You can use the library to analyze text based on polarity, subjectivity, emotion, and more. This library also works with emoticons and emojis.
The Sentiment property of TextBlob returns a named tuple that contains the polarity and subjectivity of a given sentence. The score is between 0.0 and 1, and lower values indicate the subjectivity and polarity of a statement. If the subjectivity score is lower than one, then the text contains personal opinion while a higher value means that it is objective. TextBlob is a good library for beginners to learn NLP. Its API is simple and makes it easy to use.
It analyzes tweet text, networks, and geographical origin
Using Twitter’s social network, geolocation can be inferred. Researchers have employed various techniques to infer location of tweets, including geo-tagging and geographic references in the tweet text. See the article : What Font Does Twitter Use?. Using a model that accounts for topic variation, geographically coherent linguistic regions, and user location, these methods are able to geo-localize tweets. While achieving poor accuracy, they have reported a median error of 494 km.
Twitter produces hundreds of millions of messages every day. Users talk about all kinds of topics, from politics to pop culture. Twitter makes it possible to access thousands of tweets in minutes. In this course, you’ll learn how to collect Twitter data, analyze tweet text, networks, and geographical origin, and use Twitter hashtags to perform data science analysis. Along with this, we will cover some recent events like the State of Union address.
It calculates polarity values of individual tweets on climate change
In order to determine what kind of sentiment people have about climate change, you can analyze text data. One method is sentiment analysis. Text analysis is done by identifying attitudes based on their polarity values, which are numbers between one. The higher the polarity, the more positive the sentiment. A Python package called textblob can calculate polarity values for individual tweets.
This Python package can analyze individual tweets, remove urls, and use emojis to express sentiment. The data in the /root/nltk_data directory are extracted using the textblob package. Each tweet can contain a polarity value, as indicated by its attribute.polarity. This algorithm can also identify a tweet’s polarity score using its attribute.polarity().
