Features for combined performance

not(T)	Team T did not nominate any gene mention that overlaps with this candidate.
nom(T)	Team T nominated a gene mention that overlaps with this candidate.
Noms(T, S)	Team T nominated a gene mention that overlaps with this candidate, and that starts before (S = -1), starts after (S = 1), or coincides with the start of this candidate (S = 0).
Nome(T, E)	Team T nominated a gene mention that overlaps with this candidate, and that ends before (E = -1), ends after (E = 1), or coincides with the end of this candidate (E = 0).
nom(T, S, E)	Team T nominated a gene mention with S and E as above.
Noms(S)	Some team nominated a gene mention with S as above.
Nome(E)	Some team nominated a gene mention with E as above.
word(W)	Word W occurs in the candidate.
firstword(W)	Word W is the first word of this candidate.
lastword(W)	Word W is the last word of this candidate.
context(P, W)	Word W at position P relative to this candidate. The possible values for P are -2,-1,1,2.
