Diffbot vs Semantria: What are the differences?

Diffbot: A robot that sees the web the way people do, and helps developers extract the important parts from any web page. Our APIs use computer vision, machine learning and natural language processing to help developers extract and understand objects from any Web page. We've determined that the entire Web can be classified into approximately 18 structural page types. From this basic understanding of common page layouts, Diffbot then uses computer vision, natural language processing and other machine learning algorithms to identify and extract the important items from within these pages; Semantria: Text analytics and sentiment analysis API. Semantria applies Text and Sentiment Analysis to tweets, facebook posts, surveys, reviews or enterprise content.

Diffbot and Semantria are primarily classified as "Article API" and "NLP / Sentiment Analysis" tools respectively.

Some of the features offered by Diffbot are:

• The Article API is used to extract clean article text from news article web pages.
• The Follow API allows you to subscribe to the changes of any web page.
• The Frontpage API takes in a multifaceted “homepage” and returns individual page elements.

On the other hand, Semantria provides the following key features:

• Supports C++, Java, .Net, PHP, Python, Ruby, Javascript
• Excel add-in installs and runs directly in your Microsoft Excel
