Frequently Asked Questions

What is Natural Language Generation (NLG)?

Natural Language Generation (NLG) is a subfield of artificial intelligence (AI) that focuses on generating human-like natural language text or speech from structured data or raw input. It aims to automate the process of content creation by enabling computers to generate high-quality, coherent, and contextually appropriate narratives.

How does NLG work?

NLG systems typically involve five main steps: data preprocessing, content determination, discourse planning, sentence realization, and surface realization. In the data preprocessing phase, the system transforms structured or unstructured data into a suitable format for NLG. Content determination involves selecting relevant information and deciding on the overall message and structure. Discourse planning determines the order and coherence of sentences. Sentence realization converts abstract content into actual sentences, while surface realization generates the final text, including aspects like grammar and style.

What are the applications of NLG?

NLG has numerous applications across various industries. It is used in customer service chatbots, virtual assistants, automated report generation, e-commerce product descriptions, news and sports article generation, data visualization, and more. NLG can assist in automating repetitive tasks, providing personalized content, and enhancing information delivery.
