Understanding how the human brain works is a topic of active research and several scientists from various fields publish numerous of papers every year. Why is it important? Because knowing how our brain works will enable us to understand how we operate/think and perhaps enable us build truly intelligent machines in the future. The first […]
In this tutorial we will discuss about Naive Bayes text classifier. Naive Bayes is one of the simplest classifiers that one can use because of the simple mathematics that are involved and due to the fact that it is easy to code with every standard programming language including PHP, C#, JAVA etc. Update: The Datumbox […]
The Datumbox API can be used by any modern computer language which enables you to generate web requests. Our Machine Learning API can easily be implemented within minutes because it uses REST and JSON technologies and because all the requests are authenticated simply by passing your API Key. To test the API all you need […]
Sentiment Analysis (detecting document’s polarity, subjectivity and emotional states) is a difficult problem and several times I bumped into unexpected and interesting results. One of the strangest things that I found is that despite the fact that neutral class can improve under specific conditions the classification accuracy, it is often ignored by most researchers. During […]
In this article we will see how we can build a WordPress plugin which uses Machine Learning to block spam, adult or even negative comments from our blog. The plugin is compatible with WordPress 3.6v or higher and uses Datumbox API 1.0v. Even though this article discusses the development of a WordPress plugin, we should […]
In my Thesis project for the MSc in Statistics I focused on the problem of Sentiment Analysis. The Sentiment Analysis is an application of Natural Language Processing which targets on the identification of the sentiment (positive vs negative vs neutral), the subjectivity (objective vs subjective) and the emotional states of the document. I worked on […]
In this article we will show how you can build a simple Sentiment Analysis tool which classifies tweets as positive, negative or neutral by using the Twitter REST API 1.1v and the Datumbox API 1.0v. Even though the examples will be given in PHP, you can very easily build your own tools in the computer […]
Machine Learning is a fascinating era. It is when Computer Science joins forces with the Statistical Science and magical things popup. Why is that? Because by applying knowledge from both fields you are able to analyze a large amount of information, detect patterns, predict future outcomes and extract knowledge. If I am to give a […]
