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: Blue Spice provides Indian food in the less than £20 price range. It is located in the riverside.
Example Output: [['Blue Spice', 'food', 'Indian'], ['Blue Spice', 'priceRange', 'less than £20'], ['Blue Spice', 'area', 'riverside']]

Example Input: The Rice Boat is a Japanese restaurant in the city centre, right near the Express by Holiday Inn. It is very high-priced and has only received a 3 out of 5 customer rating, and is not child friendly.
Example Output: [['The Rice Boat', 'eatType', 'restaurant'], ['The Rice Boat', 'food', 'Japanese'], ['The Rice Boat', 'priceRange', 'high'], ['The Rice Boat', 'customer rating', '3 out of 5'], ['The Rice Boat', 'area', 'city centre'], ['The Rice Boat', 'familyFriendly', 'no'], ['The Rice Boat', 'near', 'Express by Holiday Inn']]

Example Input: The American Journal of Mathematics was first published in 1878 and is abbreviated to Am. J. Math. It has the ISSN number "0002-9327".
Example Output:
[['American Journal of Mathematics', 'ABBREVIATION', '"Am. J. Math."'], ['American Journal of Mathematics', 'FIRST_PUBLICATION_YEAR', '1878'], ['American Journal of Mathematics', 'ISSN_NUMBER', '"0002-9327"']]
