For the purposes of modelling word-meanings, we might think of ‘orthogonal’ as a model for ‘com- pletely unrelated’ (having similarity score zero). This makes perfect sense for information ... retrieval of the positive term for all forms of negation. Constant subtraction is the worst af- fected, performing noticeably wors e than vector negation. • All three forms of negation still remove...
