Function to find references and contexts within articles?

Questions
1

One can find cities, currency etc in text.
Is there a function that returns all references such as (Alpha, 2014) from a
research article (PDF, Word, HTML, etc.) from the web or on a local drive?
AND
Returns the context (sentences surrounding the reference) for the reference?
AND
Returns the actual title and source from the Reference list at the end of an article.

Thanks for you input,
Harold

The first step I would suggest is checking out TextCases:

For example, this code looks through the Wikipedia article for “Economy” and returns sentences containing something recognized as a Country:

TextCases[WikipediaData["Economy"], Containing["Sentence", "Country"]]

I’m going through Digital Research Methods with Mathematica by William Turkel. There is a post announcing it here: Turkel’s book and you can go to his website here. It’s an interactive notebook that will teach you what you are looking for. It’s free.

I did look at that and figured that if countries could be recognized then a well structured this auch as “reference” could be understood.
But if not already understood, how to teach it to the language?

Another reply came in about a book which I am eager to look at.

Thanks so much

Wow, this should make me wiser.
Hope to find that I can define “reference”.

Much appreciated,
