There are several English constructions in which a certain constituent appears to the left of its canonical position, typically sentence-initially, leaving its canonical position empty. Such constructions involve Left-dislocation and Y-movement. These operations are called ‘Preposing.’ The preposed constituent of such constructions is generally regarded as the topic of the sentence which involves that constituent. Topics must have at least two features; ‘aboutness’ and ‘givenness.’ The feature ‘aboutness’ defines the range of comment, and the feature ‘givenness’ means ‘informationally old or given.’ The purpose of this paper is to show that the function of Preposing is to reinforce the aboutness of the preposed constituent of a sentence and that most preposed constituents have givenness. We examined Preposing for this purpose. Tough-movement and Passivization were examined also, because they have characteristics informationally similar to those of Preposing.

Korean is well-known for its topic-prominent properties. In this paper, we look into several subtypes of topic constructions whose grammatical complexities have received much attention in generative grammar. From a semantic/pragmatic view, topics in Korean can be classified into three different types: aboutness, contrastive, and scene-setting. Meanwhile, syntax can classify topic constructions into two types, depending on whether or not the comment clause following topic has a syntactic gap linked to the topic. In this paper, we review some key properties of these topic constructions in Korean, and suggest that each type is licensed by tight interactions between syntactic and semantic constraints. In particular, the paper tries to offer a Construction Grammar analysis where each grammatical component is interacting in non-modular ways and in which the multiple inheritance network of constructions plays an important role in capturing cross-cutting generalizations of the topic constructions.

This study intends to make a comprehensive inquiry into the quality of subject data in library catalogs. On the basis of National Library Subject Headings (NLSH) developed in 2002, National Library of Korea (NLK) has input the subject data into cataloging records since 2003. However a serious question could arise regarding whether the data are appropriate and desirable as a subject of the work. Under these circumstances, this study examined as follows: First, the meanings and attributes of the 'subject' were examined with a comprehensive literature survey. Second, a experimental analysis was carried out to measure the quality of the subject data. Sample records were selected from NLK, LC and A university library in Korea, and absolute and relative quality were compared. Finally, the substantial and realistic strategies for improving the quality of subject data were discussed.

The purpose of this study is to compare and analyze the functions and characteristics of search interfaces of Korean Old and Rare Collection Information System(KORCIS) and Korean History Online. The checklist of OPAC functionalities proposed by Breeding was used to examine eleven functions of these systems. Both system provide the following functions: Search by keywords; Boolean operators in queries; Order results chronologically; Modify search without re-keying the initial terms ; Search within result sets ; and Ability to limit results to an individual library or education. They do not provide such functions as Browse by author, title, subject and View and recall the search history for the current session. Adoption of standard OPAC and next-generation catalog functionalities, in-depth understanding of user needs and information seeking behaviors, and the improvement of subject access to these systems are suggested in this study.

The mobile social networking application Instagram is a well-known platform for sharing photos and videos. Since it is folksonomy-oriented, it provides the possibility for image indexing and knowledge representation through the assignment of hashtags to posted content. The purpose of this study is to analyze how Instagram users tag their pictures regarding different kinds of picture and hashtag categories. For such a content analysis, a distinction is made between Food, Pets, Selfies, Friends, Activity, Art, Fashion, Quotes (captioned photos), Landscape, and Architecture image categories as well as Content-relatedness (ofness, aboutness, and iconology), Emotiveness, Isness, Performativeness, Fakeness, "Insta"-Tags, and Sentences as hashtag categories. Altogether, 14,649 hashtags of 1,000 Instagram images were intellectually analyzed (100 pictures for each image category). Research questions are stated as follows: RQ1: Are there any differences in relative frequencies of hashtags in the picture categories? On average the number of hashtags per picture is 15. Lowest average values received the categories Selfie (average 10.9 tags per picture) and Friends (average 11.7 tags per picture); for highest, the categories Pet (average 18.6 tags), Fashion (average 17.6 tags), and Landscape (average 16.8 tags). RQ2: Given a picture category, what is the distribution of hashtag categories; and given a hashtag category, what is the distribution of picture categories? 60.20% of all hashtags were classified into the category Content-relatedness. Categories Emotiveness (about 4.38%) and Sentences (0.99%) were less often frequent. RQ3: Is there any association between image categories and hashtag categories? A statistically significant association between hashtag categories and image categories on Instagram exists, as a chi-square test of independence shows. This study enables a first broad overview on the tagging behavior of Instagram users and is not limited to a specific hashtag or picture motive, like previous studies.

The subject heading is an elaborate access tool for subject browsing and searching in information retrieval environment. The purpose of this study is to suggest the applicable facets to subject headings in Korea. First, the concepts of subject and the definitions of facets were investigated in the literature review. Second, six cases including OCLC's FAST, PRECIS, "Thesaurus construction and use", CC $7^{th}$ edition, BC $2^{nd}$ Edition, and UDC $3^{rd}$ Edition were analyzed to focus on configuration of facets as case studies. Based on the results, twenty-two facets were proposed including Topical, Event, Geography, Chronology, Personal and Corporate Name, Title, Form, Genre, Language, and Person facets as 11 top facets. Also, Topical-Thing/Entity and Topical-Action/Status, Part, Kind, Property, Whole, Material, Patient, Product, By-Product and Agent facets as sub-facets of Topical facet.
