ShinySentimentAnalysis

Shiny app for John Hancock Text Analytics Core

################################################################################################################

Description: R code to create a shiny app for text analytics including sentiment analysis

Author: Shatrunjai P Singh

Date: 12/17/2016

File: server.R file and ui.R file

################################################################################################################ To run this app: a) Open R, and b) Type in the following commands:

    install.packages("shiny")
    library(shiny)
    runGitHub( "ShinySentimentAnalysis", "shatrunjai") 

################################################################################################################

Here I use shiny to develop an app which can do the following:

  • Perform sentiment analysis on words,
  • Perform sentiment analysis at sentense level,
  • Get sentiment across a document
  • Creat word frequencies
  • Create a word cloud
  • Mark positive and negative lines within text

I use sentimentr, worldcloud, topicmodeller and tm packages for this analysis.
