The boy in addition to the friend is delayed.
In the above case 'friend' is identified as E-NP-singular but for:
The boy in addition to his friend is delayed.
Here 'his' and 'friend' are identified as B-NP-plural and E-NP-plural respectively.
The disambiguator log is:
REMOVE_POS_NNP_LOWERCASE_CHEMICAL_SYMBOLS -> in[in/IN,in/NN,in/RP,B-PP]
IN_NNUN -> in[in/IN,B-PP]
DT_VB_NN -> friend[friend/NN,E-NP-singular]
VBN_VBD -> delayed[delay/VBN,I-VP]
Can anyone guide me how to correct this?
