An adjective modifying a quantified expression agrees in case with the noun, not the numeral.
Example 11.1. Case agreement in counted phrases
1x. Lemma equal to the form, e.g. 1x. Tag Cv-------------.
4x5. It should be tokenized into three tokens, e.g. 4, x-5_^(náhr._symbolu_krát), and 5.
tři stovky, dvacet tisíc lidí, necelých 9000
sto and pětiset in sto-, pětiset- a tisícikoruny
Not solved. The closest existing tag is the one of first parts of hyphenated adjectives (A2--------A----). But a lemma of a numeral should not have an adjectival tag.
Domníváme se, že poslední půl miliardy let udržuje...
What case should poslední get? Does it agree with půl (accusative), or with miliardy (genitive)? Solution: genitive should be preferred.
za těch patnáct let: patnáct = accusative, těch = genitive.
Výsledkem bylo zase jen pár marek. pár can be a numeral (C...[2367]) or a noun (N...[14]). But in this particular context, it should be C due to agreement with the predicate and N due to the nominative case. Solution: use ClXP1----------, the morphological analyzer must be adjusted.
