`default_transforms()` Missing cosine_similarity Transform for Docs with Token Count 101–500

ner_overlap_sim,

),

you forgot to add the cosine_sim_builder transform to the list of default transforms. While you instantiated the cosine_sim_builder object, you did not include it in Parallel(cosine_sim_builder, ner_overlap_sim), as you did in:

[default.py#L126](https://github.com/explodinggradients/ragas/blob/2bc29a2b8358ddb6b167fdf7ab0518ad9371463c/src/ragas/testset/transforms/default.py#L126C13-L126C59).

This omission might impact the number of relationships created in the knowledge graph.

Can you share the problem you are facing?

[rgrizzo-linksmt]

The default_ transforms function defined at src/ragas/testset/transforms/default.py has a problem with handling transforms for documents with 101-500 tokens.

The code divides the transforms configurations based on the document's token count. Several transforms are instantiated when the "101-500" token count bins the first quartile (Q1, among them the cosine_sim_builder. While cosine_sim_builder is correctly instantiated (line 139), it's then not included in the list of transforms that are actually returned (line 153).

It appears that cosine_sim_builder was likely unintentionally omitted from the returned transforms list. The intended behavior should probably mirror how ner_overlap_sim is handled (line 120), where cosine_sim_builder is instantiated and added to the returned list. The current code effectively instantiates cosine_sim_builder but then discards it. This omission might impact the number of relationships created in the knowledge graph.

Hoping this can help you understand the problem I'm facing!

Accha got this,
In src/ragas/testset/transforms/default.py
Instead of line 157 to be ner_overlap_sim,
this should be Parallel(cosine_sim_builder, ner_overlap_sim).

This makes sense.

@rgrizzo-linksmt I think you should raise a PR for this.
