Costs are a lot lower than building a custom-made sentiment analysis solution from scratch. There are a variety of pre-built sentiment analysis solutions like Thematic which can save you time, money, and mental energy. The first step is to understand which machine learning options are best for your business. You’ll need to consider the programming language to use as well.

The relationship extraction term describes the process of extracting the semantic relationship between these entities. The computer’s task is to understand the word in a specific context and choose the best meaning. For instance, the word “cloud” may refer to a meteorology term, but it could also refer to computing.

The Cloud NLP API is used to improve the capabilities of the application using natural language processing technology. It allows you to carry various natural language processing functions like sentiment analysis and language detection. Deep contextual insights and values for key clinical attributes develop more meaningful data. Potential data sources include clinical notes, discharge summaries, clinical trial protocols and literature data. Speech recognition, also called speech-to-text, is the task of reliably converting voice data into text data.

What is natural language processing?

For example, a machine learning model can be trained to recognise that there are two aspects with two different sentiments. It would average the overall sentiment as neutral, but also keep track of the details. IBM Watson API combines different sophisticated machine learning techniques to enable developers to classify text into various custom categories. It supports multiple languages, such as English, French, Spanish, German, Chinese, etc. With the help of IBM Watson API, you can extract insights from texts, add automation in workflows, enhance search, and understand the sentiment.
