I had an idea to make a rudimentary version of this myself, using the Python Natural Language Toolkit. To make this work, I needed a bilingual corpus, which had the same sentences in both Cornish and English.
The electronic version of the Cornish language textbook Skeul an Yeth 1 by Wella Brown, has been made available online free by Kesva an Taves Kernewek (The Cornish Language Board).
This contains a list of example sentences at the end of every chapter, which provides the bilingual corpus for this work.
What the program does is to ask for an input sentence (currently only via the command-line) in English, and then find the 'bigrams' and 'trigrams' in it, and also do so for the sentences from Skeul an Yeth 1.
The program uses the NLTK 'stopwords' corpus, to filter the bigrams/trigrams for whether they are in a list of common words that may not have much in the way of lexical content. Sentences containing trigrams containing at least 1 non-stopword are listed first, followed by bigrams with at least 1 non-stopword, followed by trigrams and bigrams that consist solely of stopwords.
For a larger corpus the numbers of sentences found for common bigrams such as ('in', 'the') could become very large.

The cat is sleeping on the floor next to the fire.
trigrams for input sentence are:
[('the', 'cat', 'is'), ('cat', 'is', 'sleeping'), ('is', 'sleeping', 'on'), ('sleeping', 'on', 'the'), ('on', 'the', 'floor'), ('the', 'floor', 'next'), ('floor', 'next', 'to'), ('next', 'to', 'the'), ('to', 'the', 'fire'), ('the', 'fire', '.')]
bigrams for input sentence are:
[('the', 'cat'), ('cat', 'is'), ('is', 'sleeping'), ('sleeping', 'on'), ('on', 'the'), ('the', 'floor'), ('floor', 'next'), ('next', 'to'), ('to', 'the'), ('the', 'fire'), ('fire', '.')]
