This work first aims to formalize the morph-syntactic Negation in Quechua and construct NooJ grammars, which could be used in text analysis to retrieve sentences with sentiment. We analyze positive or negative evaluations of sentimental expressions using NooJ local grammar and try to obtain a classification ‘degree’ of sentiment. We consider the typological question of Quechua as a multiple-negation language, manam chusaqchu [it is not empty], and study the use of double negatives as equivalent to affirmative constructions, manam wasinaqchu [lit. He is not someone who does not have a house]. The Quechua language has several types of Negation: lexical mana[no], mana munanchu mikuita [he does not want to eat], morphological kanchu [there does not] manam qullqi kanchu [there is no money], syntactic manaraqmi chayamunchu [he has not yet arrived] and semantic mikunmanñachu saksasqa kaspaqa [If he were satisfied, he would not eat]. A negative sentence employs the suffix chu [Negation] and the adverb mana [no] preceding the predicate and present sentences, such as mana mikunchu [he does not eat], which is opposed to mikunmi[he does eat]. In order to use morph syntactic grammar, it is necessary to analyze the remarkable property of this negation adverb mana [no] and after the construction of the formal corresponding grammar containing one adverbial-suffix or combination of two or three of those suffixes. We present the inflected forms of the ‘no’ adverb: manaraq[not yet] and manapaschá [probably non], which help generate negative paraphrases.
