    Function to check if two strings have an unordered EM or not,
    without the non-semantic nodes. Entity resolution step will be performed on
    the semantics only tree representation for string_1. This function is only applicable for
    TOP format string_1. The second string_2 will be loaded as an EXR format string.
    This function returns False if either of the two input strings aren't in valid formats
    using which a tree can be constructed.

    :param string_1: input string 1, TOP format, will undergo ER
    :param string_2: input string 2, EXR format, will NOT undergo ER
    :param resolver: a resolver object from entity_resolution.py

    :return: (bool) A bool value indicating if string 1 and string 2 are
        semantics only unordered EM or not after entity resolution is performed
        the tree obtained from string 1 and semantics only transformation was applied.
