Here's some pythonesque pseudo-code that might do it: for tweet in twitter_api.latest_tweets(): phonetic_tweet = convert_tweet_to_phonemes(tweet) if is_iambic(phonetic_tweet): end_rhymes = extract_end_rhymes(phonetic_tweet) db.insert_iambic_tweet(tweet, end_rhymes) for end_rhyme in end_rhymes: rhyming_tweets = db.select_rhyming_tweets(end_rhyme) if rhyming_tweets: rhyming_tweet = random.choice(rhyming_tweets) return [tweet, rhyming_tweet] There are several open source word lists out there that make this feasible.
