● Aspect-based sentiment analysis breaks down a review into smaller segments, and studies
them for sentiment, thus enabling more detailed and accurate insights. Aspect-based
sentiment analysis can easily help distinguish which features of a product or service are liked
and which ones can be improved.
● Let’s see an example
● Went to Bar Chef last night and loved their drinks, especially the martinis, but the food was
horrible. My nachos tasted microwaved and the calamari was rubbery.
● This review needs to be analyzed at the aspect sentiment level, with further aspect insights
on Drinks (martinis), and Food are revealed through the aspects of nachos and calamari.

Repustate’s video content analysis tool conducts aspect based
sentiment analysis on YouTube videos to deliver the most granular
brand insights. It uses advanced named entity recognition (NER) to
identify named entities in YouTube videos and classifies them into
predetermined categories. NER classifies company names, geo-
locations, things, and names of people who are mentioned in the
videos. These insights thus can be used to improve marketing
efforts, products, customer experience, or customer service.

● Step 1: Collect & prepare video/audio/image/text data
Videos are converted into text using speech-to-text transcription models and run through
neural networks (NN) for audio content analysis. These NNs also discover caption overlays
in videos, and if detected, they read and extract text from it. They also employ image
detection for logos in background imagery.
All this video data, along with text data from the comments is collected and manually
edited to remove redundancies, punctuations, gifs, emojis, etc. It is then converted in a
machine-readable format (CSV, XLS, JSON) so it can be ingested into the machine
learning pipeline for training.

● Step 3: Visualize insights
Sentiment scores are presented in the form of visual reports consisting of
charts, graphs and tables through a sentiment visualization dashboard.
