UNLWS can definitely be described as being based on "predicate calculus" (as in formal logic). I personally have never felt it to be a very apt or helpful description — I think of it more in terms of Lakoff-style "frames". However, every glyph in UNLWS, including the all-pervasive minimal glyph (a dot, which is implicitly in any line), is a predicate.
FWIW, no this isn't how Chinese works — and it isn't ideographic. Hanzi (& Japanese kanji) have both semantic and rhyme hinting components, and aside from a few words that are nearly minimal in their use of radicals (the components), are generally vastly underspecified to get the meaning of the grapheme unless you know it.
