🙆🏻♀ This is a practical text mining project. 🙆🏻♂
This course covers everything from data collection to sentiment analysis and data visualization!
You've learned the basics of programming, crawling, and even taken a text mining course, but are you still feeling overwhelmed when it comes to actually working on a project? This course walks you through a project from start to finish with me.
I use Naver Maps to collect a list of restaurants near my house.
After setting keywords that can be searched on the blog, we collect blog data for each restaurant.
🌈 Sentiment Analysis of Restaurant Data
We train a sentiment analysis model based on supervised learning and build a sentiment dictionary with an accuracy of up to 80%.
Apply sentiment analysis to blog data based on the built dictionary.
🌈 Restaurant Ranking and Data Visualization
We apply sentiment analysis to each restaurant to rank them and visualize them on a map.
Additionally, we will draw a word cloud for each restaurant.
Q. Can I listen without knowing R at all?
A. You should have a basic understanding of R, web crawling, and text mining to easily follow this course. 😭😭. I recommend taking the free R Programming Fundamentals course and the Text Mining course. I've also uploaded basic information on web crawling and sentiment analysis (web crawling practice, text mining lecture videos). If you find these courses easy to follow, you don't need to take the other courses!

My primary research areas are data science, reinforcement learning, and deep learning.
I am currently doing crawling and text mining as a hobby :)
I developed an app called Marong that uses crawling to collect and display only popular community posts,
I also created a restaurant recommendation app by collecting lists of famous restaurants and blog posts from across the country :) (it failed miserably..)
I am currently a PhD student researching artificial intelligence.
I even developed a restaurant recommendation app by collecting blog posts and lists of top-rated restaurants across the country :) (though it failed miserably...) Now, I am a PhD student researching artificial intelligence.
I even developed a restaurant recommendation app by collecting lists of famous restaurants and blogs from all over the country :) (It failed miserably...) Now, I am a PhD student researching artificial intelligence.
