polarity with negator and oposing polarities #203

Closed trinker closed 9 years ago

trinker commented 9 years ago

Consider...

counts(polarity("notebook is a good but i love batterytop"))
counts(polarity("notebook is not good but i love batterytop"))
> counts(polarity("notebook is a good but i love batterytop"))
  all wc polarity  pos.words neg.words                                 text.var
1 all  8    0.707 good, love         - notebook is a good but i love batterytop

> counts(polarity("notebook is not good but i love batterytop"))
  all wc polarity  pos.words neg.words                                   text.var
1 all  8   -0.707 good, love         - notebook is not good but i love batterytop

I'd expect the outcome to be 0 polarity for the second one. It seems the negator is negating everything, not just that chunk.

This is expected now as the not is included in the second chunk and thus negates both chunks. Consider:

counts(polarity("notebook is not good but i WORD love batterytop"))

##   all wc polarity  pos.words neg.words                                        text.var
## 1 all  9        0 good, love         - notebook is not good but i WORD love batterytop
