FLAN-T5 small-WordNet

This model is a fine-tuned version of flan-t5-small on the WordNet dataset.

Model description

The model is trained to classify terms into one of four term types: noun, verb, adjective or adverb. The types themselves are learned and then generated by the model with no more than one type associated with a specific term.

The model also works well as part of a Retrieval-and-Generation (RAG) pipeline by leveraging an external knowledge source, specifically Wordnet Semantic Primes.

Intended uses and limitations

This model is intended to be used to generate a type (class) for an input term.

Training and evaluation data

The train size is 40559.

The test size is 9470.

Example

Here's an example of the model capabilities:

• input:
