Analysis of Korean Predicative Verb Forms in LAG Framework

The so-called serial verb construction (SVC) is a complex predicate structure consisting of two or more verbal heads but denotes one single event. This paper first discusses the grammatical properties of Korean SVCs and provides a lexicalist, constructionbased analysis couched upon a typed-feature structure grammar. We also show the results of implementing the grammar in the LKB (Linguistics Knowledge Building) system couched upon the existing the KRG (Korean Resource Grammar) which has been developed since 2003. The implementation results provides us with a feasible direction of expanding the analysis to cover a wider range of relevant data.

The purpose of this paper is to provide an Indexed PSG analysis of light verb constructions in Korean. These constructions have some special properties which cannot be accounted for easily. Firstly, predicate nominals rather than light verbs are responsible for assigning case to their verbally case-marked complements although they are nouns. Secondly, predicate nominals and their NP-external complements are not in the same local tree and are not always adjacent to each other. Thirdly, once a predicate nominal is licensed by the light verb ha-or an aspectual noun, that predicate nominal can license another predicate nominal, which in turn can license a third predicate nominal, and so on. These properties will be shown to be analyzed effectively under an Indexed PSG framework developed in .

The lexical information of verbal lexemes, such as verbs and adjectives, plays an important role in syntactic parsing, because the structure of a sentence mainly hinges on the type of verbal lexemes. The question we address in this research is how to acquire the argument structure (henceforth ARG-ST) of verbal lexemes in Korean. It is well known that manual build-up of type hierarchy usually cost too much time and resources, so an alternative method, namely automatic collection of relevant information is much more preferred. This paper proposes a procedure to automatically collect ARG-ST of Korean verbal lexemes from a Korean Treebank. Specifically, the system we develop in this paper first extracts lexical information of ARG-ST of verbal lexemes from a 0.8 million graphic word Korean Treebank in an unsupervised way, checks the hierarchical relationship among them, and builds up the type hierarchy automatically. The result is written in an HPSG-style annotation, thus making it possi...

This article develops a semi-automatic morphological analysis module (SaCoFlexor) to generate all inflection forms of the 585 verbs in class 1 (C-I) in the Saho language registered in the current Saho Corpus as a basic data dictionary and presents the results. SaCoFlexor correctly identified 98.8% of the items present in the corpus and classified them in 4 major subcategories according to the initial phonemes of the word, with the correct generation of their inflectional morphology forms generating 13,455 new words, tagged, and linked to their respective roots. The output data increased the number of words in the Saho Corpus and improved performances of the computational linguistics functions, including word frequency generation, word identification mechanism, concordance, collocations, and spell checking.

Verbs in Korean are traditionally classified as 'main' or 'auxiliary.' For example, :sal ' lives ' and silh 'is undesirable' in (l) are 'main' verbs, whereas siph 'is desirable' is an " auxiliary' verb. 2 ( l) na-nun tosi-eyse sal-ki silh-ta. na-nun tosi-eyse sal-ko siph-ta. '1 hate to live in cities.' '1 want to live in cities.' Choi (1965 : 244-45) classifies verbs as 'main' vs. 'auxiliary', depending on whether a verb can stand by itself in a predicative function or whether it necessarily follows another verb, thereby 'helping' it. When one applies this 'stand-by-itself' test to the above three verbs, as in (2) , siph turns out to be 'auxiliary', because only (2c) is ungrammatical. (2) a. na-nun tosi-eyse sal•ass-ta. '1 lived in cities.' b. na-nun tosi-ka silh-ta. ) hate cities.' c. *na-nun tosi-ka siph•ta. '1 like cities.' By 'auxiliary' verb constructions, 1 mean those constructions where an 'auxiliary' verb ,appears. Thus, the second sentence in ( l) is an 'auxiliary' verb construction, but the first one is not. Furthermore, we may say, in traditional terms, that in "compound verb expre-,ssions•• • ... the main verb merely tells what action or quality is under discussion•••••• and is otherwise frozen; the auxiliary verb completes the expression and fits it into. the sentence 'With appropriate endings" (Martin-Lee 1969:133). 2. Recent generative analyses, however, do not distinguish between the two classes of 'verbs, claiming implicitly or explicitly that the so-called 'auxiliary' verbs in Korean are 1 This paper was presented at the Panel on Modern Linguistics and the Study of the Korean Language, 25th AAS Meeting, Chicago, March 30, 1973.

The expression kes, one of the most commonly used words in the Korean language, has various usages. This expression is also used to express English-like cleft constructions. Korean seems to employ at least three dierent types of cleft constructions: predicational, identicational, and eventual. The paper tries to provide a constraint-based analysis of these three types of Korean cleft constructions and implement the analysis in the LKB system to check the feasibility of the analysis. In particular, the paper shows how a typed feature structure grammar, couched upon HPSG, can provide a robust basis for parsing Korean cleft constructions.

Traditionally, the analysis of word structure (morphology) is divided into two basic fields as infleetion and derivation. Therefore, the morphological structure of each word may include elements such as prefix, suffix, infix, or even a separate root, and these elements can modify the meaning of the basic root or stern of the word. If the consequent word is only a paradigmatic application of its base form, this variation of the word is called inflection; but if the resulting word is an entirely different word or a compound, which is formed of two or more roots, it is called derivation. While derivation is a word-creating process, infleetion constitutes different forms of any word. The model developed in this study, which analyses the morphology of Turkish verbs, can recognize all of the inflectional categories. The computational tool consists of a Java applet that can run on every machine, and a database that has been extracted from Turkish Dictionary published by Turkish Language Society. The database includes both the verb roots and derived verbs. We utilize Koskenniemi's two-level system to develop the morphological modeL. The input verb, which precedes the suffixes, is analyzed as an invariant root by querying the database, and the following suffix particles may indicate voice (causative, reciprocal, reflexive, passive), modality (necessitive, abilitative, conditional), negation, tense-aspect mood and person/number.
