Week 7 discussion

Part A

1.Discussion (Chapter 7): What are the common challenges with which sentiment analysis deals? What are the most popular application areas for sentiment analysis? Why?

“Why do we need to understand data visualisations? There is more and more data around us, and data are increasingly used in decision-making, journalism, and to make sense of the world. One of the main ways that people get access to data is through visualisations, but lots of people feel like they don’t have the skills and knowledge to make sense of visualisations. This can mean that some people feel left out of conversations about data.” -  http://seeingdata.org/developing-visualisation-literacy/

 

Please conduct the following activity located at the following address:

 

http://seeingdata.org/developing-visualisation-literacy/rate-these-visualisations/

 

Tell us what you think of the visualisations that we used in our focus group research. Instructions below!

 

What to do

Look at the visualisations by clicking on the images below. You can choose to open the visualisation in a NEW tab or window (we recommend this) or view it in a pop-up window if you prefer to stay on this page. Some are interactive (i) and some are static (s).

Place the images on the grid. When you’ve looked at one, go to the grid and position the image according to whether you liked or didn’t like and learned or didn’t learn something from the visualisation (‘learning something’ could also mean confirming something you already knew). Only place the visualisations that you have looked at onto the grid. Click SUBMIT.

Compare your views with others. You can compare your responses to the visualisations with those of others, by clicking COMPARE.

Choose three of your favorite visualisations. Post a 3 – 5 sentence summary of why you chose the visualisations. What caught your attention? Were they effective in presenting the provided data? If possible, explain how you would you do to improve the visualization?

Part B

When submitting work, be sure to include an APA cover page and include at least two APA formatted references (and APA in-text citations) to support the work this week. All work must be original (not copied from any source).

1. Explain the relationship among data mining, text min

ing, and sentiment analysis.

2.What is the role of NLP in text mining? Discuss the capa

bilities and limitations of NLP in the context of text mining

Part C

Refer back to homework assignment 2, in week 3.  Homework assignment 2 asked you to find a data set and perform some manipulations using R.  For this assignment, you can use that same dataset, or select a new one of your choosing and use Tableau to create a visualization.  The assignment requirements are:

Go to Tableau.com and download a free trial version of Tableau

Use Tableau to create an appropriate visualization for the dataset you selected for homework assignment 2, or another dataset of your choosing.

Provide screenshots showing your steps in Tableau (at least 3)

Explain how your visualization meets the criteria of being Trustworthy, Accessible, and Elegant (1-3 paragraphs)

Explain the story that your visualization should be telling to the viewer (1-3 paragraphs)

Compare and contrast your experiences using R versus Tableau.  Which one is more user friendly?  Are there limitations to one versus the other?  (1-3 paragraphs)
