This study focused on the need to consider the feature of documents for automatic language processing such as QA, and focuses on the need for detailed guidelines for semantic roles annotation. The purpose of this paper is to improve the performance of the QA system of descriptive legal documents. In the legal document, the analysis was focused on <conditions> among high-frequency semantic roles of adjuncts, and the necessity of a new semantic roles of adjuncts was discussed. Chapter 2, explained the importance of automatic recognition of semantic roles of adjuncts in the Q & A system. Chapter 3 introduced the semantic roles of Prop Bank and ETRI, and explained the necessity of classifyingsemantic roles of adjuncts for perception of boundary clauses. In order to annotate semantic roles of adjuncts for boundary clauses, it is necessary to examine high-frequency connective endings and analyze vocabularies which is distributed before and after the connective endings. In addition, it was analyzed whether a specific semantic roles of adjuncts can be recognized according to the distribution of the connective endings. In Chapter 4, a method of sequentially applying semantic roles of adjuncts when automatically finding answers to questions about the law was proposed. In a question about the law, <time> or <extent> can be interpreted as <condition> in an answer.

This study aims to examine the grammatical basis of ‘NP+Adv’ constructions and to type them according to the syntactic relation between their internal constituents(that is a noun phrase and an adverb) and a predicate. ‘NP+Adv’ constructions are based on the semantic relation between a noun phrase and an adverb. An adverb in ‘NP+Adv’ construction is incomplete in meaning, and a noun phrase supplements the incomplete meaning of an adverb. ‘NP+Adv’ constructions are syntactically classified into two types, that is an adverb expansion AdvP and an adverbial consolidation AdvP. The adverb expansion AdvP is a construction that an adverb is syntactically related to a predicate and it is expanded by a noun phrase. The adverbial consolidation AdvP is a construction that two adverbial constituents(that is an adverbial noun phrase and an adverb) are consolidated into one. But not all adverbial constituents can be consolidated into one. They have to be semantically related to each other.

This study investigates whether three syllabic features, which are the classes of words, the types of words, and the positions in words from which orthographic syllables are drawn, have an effect on the probability for a pair of the sublexical items to be a legitimate Korean word when they are combined at random. As a result of three computational experiments, three main findings were obtained as follows: (1) the combination of a pair of syllables generated more real words when their positions in words were preserved than not; (2) the combination of a pair of syllables from a homogeneous word type produced more real words than from heterogeneous word types and the combination of a pair of sino-Korean syllables showed the higher productivity than of native Korean ones as well; and (3) the combination of a pair of syllables from a homogeneous word class created more real words than from heterogeneous word classes and the combination of a pair of noun syllables was more productive than of verb ones as well. These findings suggest that the word classes, the word types, and the positions in words have a significant impact on the probability of inter-syllabic combinations in Korean word formation, and that the syllables as sublexical units play an important role in organization of lexical representations in the mental lexicon of native speakers of Korean.
