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.
