Hi, we need to similarity between document. For example - Job description and resume. Are there any existing NLP libraries or tools or implementations?
You can solve this problem in a number of ways. Some of them I am listing below:
Extract the named entities from the documents using a Named Entity Recognition model and then see how similar 2 documents are by comparing the extracted entities.
Use Topic Modeling to extract abstract topics (ideas) from the documents and match the documents based on the dominant topics in the documents.
Use word embeddings to represent documents in terms of vectors and find similarity among them using cosine similarity score.
