This task is about using the specified sentence and converting the sentence to Resource Description Framework (RDF) triplets of the form (subject, predicate object). The RDF triplets generated must be such that the triplets accurately capture the structure and semantics of the input sentence. The input is a sentence and the output is a list of triplets of the form [subject, predicate, object] that capture the relationships present in the sentence. When a sentence has more than 1 RDF triplet possible, the output must contain all of them.

Example Input: The Phoenix has English food on the riverside with a high customer rating and a price range of 20-25.
Example Output: [['The Phoenix', 'food', 'English'], ['The Phoenix', 'priceRange', '£20-25'], ['The Phoenix', 'customer rating', 'high'], ['The Phoenix', 'area', 'riverside']]

Example Input: The fourth place was Petter Solberg with 5 points.
Example Output: [['Petter Solberg', 'POSITION', '4.'], ['Petter Solberg', 'POINTS', '5']]

Example Input: Arkady Vyatchanin is Russian and competed for the EU in lane 8.
Example Output:
[['Arkady Vyatchanin', 'NATIONALITY', 'Russia'], ['Arkady Vyatchanin', 'LANE', '8'], ['Arkady Vyatchanin', 'NOTES', 'EU']]
