Node embeddings extraction

[DiegoOrtego]

Hi!

First of all, congrats for the great work here and for sharing the code. I'm playing with the code and found that that you are using "text-embedding-3-small" as embedding model for vector search, which is not a free model. You are providing embeddings for nodes, but not for the queries, so I cannot run the full code (maybe I miss something). Anyway, I want to have full control of the models being used so wanted to try out with Qwen3-Embeddings to replace "text-embedding-3-small". However, I realized that there is no code for embedding extraction for the nodes. Could you guide me in how to do it? Do I just need to embed the node text ("texts" field from 'node_embeddings_add_rel_not_compact.pt' and 'node_embeddings_no_rel_not_compact.pt')? I guess that "texts" field in 'node_embeddings_add_rel_not_compact.pt' already contains the relational information to expand the node information with 2-hop info as you describe in the paper, right?

Many thanks in advance!

Just to clarify and extend a bit more my question. Debugging your code, I can see that the "texts" fields with relations that you are adding add relations of type brand or things like also viewed. However, sometimes some relations are not added, e.g. category relation. Also, I can't see that 2-hop relations are added there. Am I missing something?
Also, I've seen that before reviews you add some summary of the reviews with the average score and number of reviews. Where do you get this from? Just a template?

Thanks again in advance!
