Because all the subjects may become the targets of classification, it is necessary to change the enumerated into the faceted scheme. This study is to confirm that possibility of change and to proposed the new faceted structure scheme(faceted classification) based on the Literature. The proposed schemes are : 1) facet structure is simple, 2) meaning of facet is clearness, 3) because using mixed notation, it is complicated.

It is very important to organize materials at intemet bookstores. It is time for us to develop a subject classification scheme as a tool for increasing the effectiveness of information retrieval with ease of subject access. The purpose of this study is to examine the subject features of internet bookstores in order to suggest the effective design of the subject scheme for them. Nine internet bookstore websites are analyzed at the aspect of the subject classification of the materials. Based upon the results of this study, an effective subject classification for internet bookstores is suggested to provide a better subject access.

In indexing and organizing Web resources, there have been two basic methods: automatic indexing by extracting key words and library classification schemes or subject directories of search engines. But, both methods have failed to satisfy the user's information needs, due to the lack of standard criteria and the irrationality of its structural system. In this paper I have examined the limits of library classification scheme's structures and the problems related to the nature of Web resources such as specificity and exhaustivity. I have also attempted to explain the logicality of Web resources organization by facet analysis and its strengths and limitations. In so doing, I have proposed three specific methods in using facet analysis: firstly, indexing system by facet analysis; secondly, the alternative transformation of the enumerative classification scheme into facet classification scheme; and finally, the facet model of subject directory of domestic search engine. After examining the three methods, my study concludes that a controlled vocabulary by facet analysis can be employed as a useful method in organizing Web resources.

There is increasing importance of a system to reorganize explosive expansion of internet information resources efficiently; therefore, an increasing concern about classification system as an instrument for facilitating an access to a specific subject and improving efficiency in information retrieval. Comparing the hierarchical structure and access methodology of internet-based classification system with those of library classification such as Dewey Decimal Classification through their structural aspects and retrival process, this paper proposes the proper classification system in internet environment.

Time(Period table) is the chronological factor in a subject. Classification schemes are using the period tables for represent the time. CC and UDC's common auxiliary of time tables are consistence and clear. DDC and KDC are using the different way, though the notation is complicated.

The purpose of this research is to analyze the differences between electronical engineering class in KDC3 and electronical engineering class in DDC 19. The results of the study can be summarized as follows ; 1. The characteristics of the classification items in classification schemes of the electronical engineering fields is that KDC is classified by the vacuum tubes, electron tubes, special tubes, computers etc and DDC is classified by the microwave electronics, short-and long-wave electronics, X-ray and gamma-ray electronics, computers etc. 2. There is a blank in KDC and there are three blanks in DDC of the electronical engineering fields, but the total classification items number is much more in DDC than in KDC. This means that DDC is more classified than in the special classification items. 3. Classification items over 70% in the total classification items of computer fields in KDC, are classified a classification items of the short-and long-wave electronics in DDC. 4. There is a blank of computer fields in KDC and there are three blanks of computer fields in DDC, but the total classification items are many eighteen items. This means that DDC is more classified than KDC. 5. The sections of computers in DDC were established the 621.38195 classification item and the subsection of analogue computers in DDC were established the 621.381957 classification item and the subsection of digital computer in DDC were established the 621.381958 classification item. As we have seen, because of the development in technology and the subdivision of knowledge, the number of items is increased, and the terminology also become simplified and specified in the field of electronic engineering in KDC and DDC.

The purpose of this study aims to provide possible suggestions for the improvement of KDC 5th ed. in Jurisprudence Field. The research methods are as follows. First, to analyze academic fields in Jurisprudence, the contents of Jurisprudence introductory books are investigated. Second, to find out the problem of KDC Jurisprudence field, comparative analysis is done on the three classification schemes - KDC, DDC and NDC. Third, curriculum of domestic law schools are reflected. If above suggestions are adopted, effective literature classification scheme which is suited to domestic circumstances will be certainly prepared.

In this study, Two divisions(language and literature) in schemes of the DDC are discussed. And the adaptation of these divisions to the minor or oriential countries are seggested. In spite of the continuous study and revision of the experts, the frameworks of these systems are still kept unchanged. Only their subdivisions, reflecting those developments In the academic world are developed and detailed more sophisticatedly. Of those subdivisions in DDC, especially the two subdivisions of language and literature are seriously unbalanced. The two divisions give the attention too much to the Western including the English, Deutsch and French. Relatively the languages and literatures of the other nations are treated lightly. It results more problems to the Oriental and the minor nations. So, the libraries of these nations should modify the schedules and develop the subdivisions items of the local emphasis. Considering these problems the historical changes of the DDC system in the languages and literatures are clarified and the problems occurring from unbalanced allocation of the classed items are examined.

Ten Web sites from educational policy authorities, educational research institutions, professional educational, and national libraries that provide educational policy information services are investigated using content analysis method. They are analyzed using various types of information sources, classification schemes, and functions of information retrieval. Standardization of classification scheme of educational policy information, standardization of meta data items, improvement of retrieval systems, provision of personalized information services to educational policy authorities, operation of specialized policy information centers, and cooperation among professional institutions are suggested. A model of a specialized educational policy information center is proposed.

This study analyzes the concepts and background of introducing preference order in general classification schemes and investigates and analyzes the major tables of preference of DDC 21 specifically in the Tables and in the Schedules. It also suggests specific examples for application in almost all cases of the tables of preference.
