We are a group of doctors trying to use linguistic features of "Spacy", especially the part of speech tagging to show relationships between medical concepts like:

'Femoral artery pseudoaneurysm as in ==>

"femoral artery" ['Anatomical Location'] --> and "pseudoaneurysm" ['Pathology']

We are new to NLP and spacy, can someone with experience with NLP and Spacy explain if this is a good approach to show these relationships in medical documents? If not what are the other alternative methods?

Many thanks!

Based on the example, it looks like you need more than simple POS tagging. Thankfully there is a full subdomain of NLP devoted to biomedical data, and there are many tools available which can help with this kind of task:

  • In case the data is made of biomedical research papers, you will find a lot of resources related to the Medline and PubMedCentral databases:
  • cTakes is another annotator system which is more specialized with clinical texts.
  • SciSpacy is a Spacy variant specialized for biomedical text. It can also annotate medical terms with UMLS labels.

The last one in particular seems particularly appropriate in your case. biomedical text presents a lot of specific difficulties which cannot be handled with general domain models.

Note that there are probably more tools and resources, this a very active domain.
