How Every Computer Scientist Should Water Plants with Arduino

Intro
It’s hard to tell how much water does a plant need. Remember those times when you had to leave for a vocation, training or a conference? You risk finding your plants dead upon your return. I always find myself unprepared when I have to travel. Once, I watered my mint and lemon balm herbs excessively to make sure the plant had enough water until I come back. Little did I know, my plant would have tiny gnat flies all over it and was covered in spider nets. Those creatures thrived in the wet environment! I had no idea that excessive watering could cause so much trouble. After I almost lost both of my herbs, I decided to solve this problem through automation.

Sentiment Analysis Methods

Abstract

As more and more information becomes freely available on the Internet, there appears to be an increasing demand for tools that would analyze information and provide valuable insights. One of such tools is sentiment analysis. The goal of sentiment analysis is to extract an opinion from text data and classify it into positive, neutral or negative. Millions of opinions, which are expressed on the Internet, about a product can be analyzed in a matter of seconds, providing insights about the appealing of the product to the general public based on the ration of positive to negative feedbacks. It is not feasible to complete such classification manually until, so the help of computer aid is needed. The goal of this paper is to overview available methods and algorithms that are commonly used for solving the problem of sentiment analysis. A basic machine learning algorithm has been built based on Naïve Classifier and Bag of Word model. The results was satisfying with a relatively height accuracy of classification.
