# Can a list of websites be considered a corpus for a particular category?

I am trying to build my own corpus for particular categories such as Engineering, Business, Math, Science and etc... This will be for automatic web page categorization. Let's say I manually collect 100 websites that are related to Math. Can these 100 websites be considered a corpus for Math?

Another related question. How does this differentiate from a lexicon wherein instead of a list of websites it shows a list of words with weights such as 0 or 1 to particular categories? Example would be a sentiment lexicon with words that has weights for positive and negative. But instead of positive and negative, categories such as Math, Science are used.

• @elJosso What would the difference be then from a lexicon? I have edited the question. – John Jul 25 '17 at 10:46
