The task is to find the relation between e1 and e2 from the label list. The relation type can have two directions (e1, e2) or (e2, e1), depending on the context of the sentence.


Given Sentence: "The <e1>author</e1> of a keygen uses a <e2>disassembler</e2> to look at the raw assembly code."
Choose one of them: relations_dict = {
    'Cause-Effect(e1, e2)': 0,
    'Cause-Effect(e2, e1)': 1,
    'Component-Whole(e1, e2)': 2,
    'Component-Whole(e2, e1)': 3,
    'Content-Container(e1, e2)': 4,
    'Content-Container(e2, e1)': 5,
    'Entity-Destination(e1, e2)': 6,
    'Entity-Destination(e2, e1)': 7,
    'Entity-Origin(e1, e2)': 8,
    'Entity-Origin(e2, e1)': 9,
    'Instrument-Agency(e1, e2)': 10,
    'Instrument-Agency(e2, e1)': 11,
    'Member-Collection(e1,e2)': 12,
    'Member-Collection(e2,e1)': 13,
    'Message-Topic(e1,e2)': 14,
    'Message-Topic(e2,e1)': 15,
    'Product-Producer(e1,e2)': 16,
    'Product-Producer(e2,e1)': 17,
    'Other': 18
}
