Finding the Symbols for Companies in a Body of Text

I am currently working in Python and I am trying to do some language processing on finance articles. However, every way I know of for querying information about a stock is via its ticker. So, my question is, do you know of a way to look up stock tickers from a general company name (not just the official name of the company) or some other way to find the ticker of a company given its name? Just as a quick example, if I were to query "Huntington Bank" on Yahoo's API or any other method I know of it will return no results (because the stock is official "Huntington Bancshares"). Possibly I might have to find the parent company of the initial query so that I am querying the correct company.

Sounds like a cool application. You could probably try creating a tuple for each company and make the values be a ticker and all possible nicknames for the company. Then you could store the tuples in a list and iterate through them to perform a search for the desired ticker.

For example,

google = ('GOOG', 'Google', 'Alphabet', 'Alphabet Inc.')
apple = ('AAPL', 'Apple', 'Apple Inc.')
netflix = ('NFLX', 'Netflix', 'Netflix Inc.')
huntington = ('HBAN', 'Huntington Bancshares', 'Huntington Bancshares Incorporated', 'Huntington Bank', 'Huntington')

companies = [google, apple, netflix, huntington]

def getTicker( str ):
    for company in companies:
        if str in company:
            return x[0]  # returns the corresponding ticker

There is probably a better way to dynamically populate your tuples and list of companies (i.e. source the tickers and company nicknames from another website or API), but I think this is a good way to organize them.

Obviously you have to prepare for common searches like 'Bank'. This would return the first company in the list whose tuple of keywords include 'Bank'.
