Top Data Science Projects
The following are the top 10 Data Science Projects that could add attraction to your resume.
1. Sentiment Analysis
The sentiment analysis is used by the present-day companies to test the preference and likeability of their products in the market. The main idea is to figure out the answers to the following questions.
- Why is the product not liked by the customers?
- Why is the product not achieving its target sales?
- What reforms can be made in the product to make it acceptable by the majority of the customers?
- Which factors affect the sentiments of the customers which can be either product quality, product quantity, product price or any other?
The sentiment analysis is, therefore, a method to analyze the opinion of the people on a particular product, service or decision taken. The opinions can range from positive to negative in polarity. The range of responses can be kept binary like Positive or Negative. In some cases, the responses can be kept with multiple options such as Excited, Happy, No response, Sad, Angry, etc. The data science project can, therefore, make use of language R which can help in attracting the relevant inputs and thereafter analyzing them for gaining the required information from the research work. The use of the latest dataset by JaneaustenR package could also be made in this case. The use of general-purpose lexicons can be made in the sentiment analysis which includes bing, Loughran, and AFINN. Finally, we can build a word cloud that can help in displaying the results.
