How to: Collect articles’ based on category

Subject terms are often given to articles either by the authors or the journals themselves. Arcas allow the user to search articles that satisfies a given subject term using the category argument.

For example the query for a game theoretic article in arXiv would be the following:

>>> import arcas
>>> api =  arcas.Nature()
>>> parameters = api.parameters_fix(category='Game Theory')
>>> url = api.create_url_search(parameters)
'http://www.nature.com/opensearch/request?&query=dc.subject adj Game Theory'
