Sentiment analysis: This involves determining the overall sentiment expressed in a piece of text, such as positive, negative, or neutral. This can be used to gauge public opinion on a particular topic or product, or to identify areas for improvement in customer service.
Topic modelling: This involves identifying the main topics or themes covered in a piece of text, such as identifying the main topics discussed in a collection of news articles or social media posts.
Language translation: Text analysis can be used to identify and translate words and phrases from one language to another, enabling communication and understanding between speakers of different languages.
This example uses a customer
table to translate reviews from Brazilian Portuguese into English and then extract the sentiment of the translated reviews.
The final result shows the original text, the translated text in English, and the sentiment of that text.
This example shows how you can easily understand the drivers of sentiment.
It's super simple - all you need to do is use a PREDICT
function with EXPLAIN
! Infer then uses Explainable AI to examine your sentiment prediction model, and figure out what the drivers of sentiment are.
The final result shows the importance of each column (features) in your sentiment prediction model. Now you can use this information to figure out what kind of people are associated with positive, negative, or neutral sentiment.
This example shows how you can use your translated reviews to find common themes, or topics, in those reviews, using the TOPICS command.
The final result gives you the original translated view, now with a topic_name, topic_id, and a 'segment'. Segments are smaller parts of the original text, which are more specific to the topic itself. This is especially useful for longer piece of texts, with multiple topics.
