How to Build a Natural Language Generator Using AI?
Building Natural Language Generators (NLG systems) is not easy. But before we go into details let us see what is NLG (Natural Language Generation). Natural-language generation (NLG) is a software process that transforms structured data into natural language. It can be used to produce long-form content for organizations to automate custom reports, as well as produce custom content for a web or mobile application. NLG needs to choose a specific, self-consistent textual representation from many potential representations. whereas NLU generally tries to produce a single, normalized representation of the idea expressed. NLG can also be accomplished by training a statistical model using machine learning, typically on a large corpus of human-written texts.
First, Natural Language Generator building heavily depends on the purpose, just like how your written communication varies with the purpose. Let us see how your approach changes with the type of content you actually want to write. For instance, you will need to apply a lot of creativity while writing a blog post; curation requires that your content and world knowledge are based on the input document or a set of documents/pages; while reports are mostly based on templates & use Natural Language Generation AI to realize the sentences and NLG for chatbots requires NLU/intent engines in addition to templates applied to outputs.
For certain content, Natural Language Generator is free to produce very similar results (chatbots, reports, etc) but for some content types, it cannot (plagiarism issues in blogs). So the randomness of the content/lexical selection varies with content types. It’s better to work backward and decide on the modules required for the NLG than going with a fixed architecture working from the top. Most research material you find online is for structured content generation using Artificial Intelligence like generating reports. So, you will have to work a bit harder than that for other content types.
