Relevancy between two sentences in python/C++/C#/Java?

Question

When you see the news from multiple sources, there could be chances for multiple sources(websites) might talk about same stuffs.

Is there any Python/C++/C#/Java library to compare the multiple sentences from different sources and identify the relevancy between them so that the result could be used for grouping of news?
