Why can't (the Noun Adjunct) 'meaning' substitute (the Adjective) 'semantic' (I bolded) in the examples below?

[ p. 33 : ] In this chapter I will discuss some semantic properties that words are traditionally supposed to have. I will concentrate on synonymy, ambiguity, and vagueness.
[ p. 40 : ] Faster processing caused by semantic similarity is called semantic priming.
[ p. 117 : ] Anaphora is the semantic dependency between pronouns and Other phrases illustrated in (2) and (7): the pronouns in these cases seem to be dependent on preceding quantifier phrases in some way for their semantic functioning.
[ p. 126 : ] So now we come to the claim about the proposition expressed that involves covert indexicals: it is that the proposition expressed is always the result of assigning referents or other semantic values to the words in a syntactic tree and then combining those semantic values by means of compositional rules.
