How To Perform Sentiment Analysis With Twitter Data

One of the most compelling use cases of sentiment analysis today is brand awareness. If you can understand what people are saying about you in a natural context, you can work towards addressing key problems and improving your business processes. So how exactly can you get that up and running?

The Algorithmia marketplace makes it easy to extract the content you need from Twitter and pipe it into the right algorithms for sentiment analysis. There are a few algorithms on the platform for exploring different information from Twitter (like users, tweets, and followers), and a number for sentiment analysis.

Build an Emotionally-Aware Chatbot in 15 Minutes

Chatbots offer a useful way to leverage the power of AI, and are now accessible for any size of application. The back-and-forth written nature of chatting is conducive to utilizing existing chatbot frameworks and AI models to automate interactions which would have required a whole team of agents just a short time ago. To demonstrate how easy it is, we’ll use a chatbot framework and a sentiment analysis model from the Serverless AI Cloud — both of which have free trial tiers.

Let’s create one now! It only takes a few minutes, and it’s free to get started. Read More…

Building a Timeline of your Video: Automatically Identify Objects, Sequence Times, and Integrate with Timeline.js

When we implemented InceptionNet, a microservice to detect and label objects (features) in photos, we knew it would be helpful. Then, we built out VideoMetadataExtraction, a video pipeline which allows you to run feature-detection algorithms (and others) on an entire video. This allowed for some really powerful activities — like automatically scanning through home security footage to find all the cars of a specific make & model, or stripping out all the nudity-containing scenes of a movie to make a G-rated version.

Today, we’ll go further by showing you how to visualize all the features in your video, thanks to the VideoTagSequencer and Timeline.js, a beautiful JavaScript library for displaying timelines on the web.

If you want to skip directly to the demo, please do. but come on back for a full breakdown of the integration pipeline and code samples! Read More…
