LexTag

Create your semantically-annotated datasets with ease

Welcome to LexTag, the ultimate tool for semantic annotation. LexTag empowers users to enrich text with precise meanings drawn from a wide array of dictionaries and knowledge graphs, including WordNet, Wiktionary, and WordAtlas. Whether you're handling academic research, content curation, or complex data analysis, LexTag provides a user-friendly interface tailored for your needs.

What is Semantic Annotation?

Semantic annotation is the process of tagging elements of text—such as words, phrases, or documents—with precise meanings derived from structured knowledge sources or inventories like WordNet or WordAtlas.

By associating text with unique identifiers or concepts from these inventories, semantic annotation helps enhance information retrieval, text analysis, and natural language processing applications.

It bridges the gap between the text's surface form and its deeper meanings, facilitating more nuanced interpretations and interactions in digital content.
