Your corpus might by wrongly tokenized. Maybe there are some OCR-related errors with word splitting something like “li-↲ king”.
You might be using a different algorithm for getting the embeddings (e....
If I understand correctly, you're trying to map abstracts to their research papers.
Here is a simple starting point:
Compute a TF IDF model using the entire corpus (all abstracts + research papers). Use this model to transform your abstracts and research papers into a weighted vector representation. Under the TF IDF weighting scheme, these documents will ...
