Manipulate and save a DocumentSet object after loading.

[rjavierch]

Hello, I am wondering how possible is to manipulate (like in a pandas table) and save a loaded DocumentSet such as .bib, ieee_csv. Or also manipulate and save the data after doing a refinement (for example using refine_scupos).

Thank you!

Hi

Manipulating the documents themselves is not possible. You can, however, manipulate a DocumentSet which contains a list of documents by, for example, calculating the intersection, union, or differen between sets (see DocumentSet)

and save a loaded DocumentSet such as .bib, ieee_csv.

Saving a document set is not possible, but it is a highly requested feature. There are open issues for saving a document set as a Bibtex file or RIS file:

• #12
• #13

Of you interesting in looking into these, we welcome all relevant pull requests!

I was looking for this as well. A possible workaround might be to just Export the documentset to a csv and later Reimport it if needed. Or is there any other way to not lose my progress everytime I shut down my machine? I mean, there must be a database saved somewhere, or is all this data sitting in the memory?

Which fields are called from the api upon refine? Is it all the ones from the class litstudy.types.Document?

Alternatively you could pickle the document set which takes less space than a csv. After that you can reload it whenever you would like to perform further analysis on the set. Just use these code snippets:

to save: with open("data.pickle", "wb") as f: pickle.dump(data, f, protocol=pickle.HIGHEST_PROTOCOL) to load: with open("data.pickle", "rb") as f: data = pickle.load(f)
