• Syntax Analysis: Parse sentences into subject-action-object form and identify entities and keywords that are subjects or objects of an action.

Metadata Extraction

Watson NLU can extract various types of metadata from text, including:

• Concepts: Identify high-level concepts that may not be directly referenced in the content.
• Categories: Categorize data using a five-level classification hierarchy.
• Relations: Understand the relationships between entities within the content and identify the type of relation.
• Semantic Roles: Analyze the semantic roles of entities in the text.

Customization and Domain Support

• Domain Customization: Extend NLU capabilities with custom models developed using Watson Knowledge Studio to identify industry/domain-specific entities and relations.
• Broad Language Support: Support multiple languages, including English, Arabic, Chinese (simplified), Dutch, French, German, Italian, Japanese, Korean, Portuguese, Russian, Spanish, and Swedish, with more languages being added.
