Visualization
There are many different methods and ways to study Twitter data. Unlike more traditional text (e.g. books), discourse on twitter can encompass a wide range of perspectives, ideas, thoughts, and context. The analysis of this discourse is something that needs that requires different cleaning methods, refinement, and categorization.
This is an tutorial about how to use the voyant tool for text analysis. The tutorial starts with very basic function of voyant tools and then go deeper for the function that can be used in text analysis-using knot to visualize the text.
This tutorial teaches how to load raw data, sample it and visually explore and present it by using Bokeh and Pandas libraries in python.
This tutorial covers :
- how to load tabular CSV data
- how to perform basic data manipulation such as aggregating and subsampling raw data
- how to visualize quantitative, categorical, and geographic data for web display
- how to add varying types of interactivity to your visualizations.
This tutorial is about how to chart time series data with line plots and categorical quantities with bar charts. How to summarize data distributions with histograms and box plots. How to summarize the relationship between variables with scatter plots.
This recipe is part of the Text Analysis for Twitter Research (TATR) series and describes how to begin plotting basic graphs using Twitter data.
This recipe is part of the Text Analysis for Twitter Research (TATR) series. The recipe will look at categorizing text using the General Inquirer Categories released by Harvard.
This recipe is part of the Text Analysis for Twitter Research (TATR) series. In this recipe we will show you how to use a dataset of Tweets to find the most popular hashtags by date. The results can then be manipulated by placing them in a Panda dataframe and visualized by plotting the most popular hashtag points over time.
Multiple Correspondence Analysis (MCA) is a data analysis technique that can detect and represent the underlying structures of a dataset. In terms of textual analysis, we can identify and graph simultaneously occurring variables from the texts that comprise a corpus.
You can retrieve the MCA module at https://pypi.python.org/pypi/mca/1.0.3, or by typing the following line in the Python terminal:
pip install --user mca
In this recipe, we measure a corpora to determine authorship of the featured texts and visualize them by authorship. We will use Multidimensional scaling(MDS) as one of the techniques for analyzing similar / dissimilar data. This recipe if based on Jinman Zhang's Cookbook on Github.
This recipe with show you how to prepare Voronoi diagrams, one way of showing relationships between words in a text and a search term. In order to do this, we will employ the use of word embeddings. These represent individual words in a text as real-valued vectors in a confined vector space. This recipe is based on Kynan Ly's cookbook as seen on this notebook.
