This study aims to perform an evaluation of directory services provided by major Korean search portals: Naver, Daum, Yahoo-Korea, and Empas. A directory service of Open Directory is also compared. These directory services are evaluated in terms of the coverage, category creation criteria, site selection criteria, breadth and depth of hierarchy, clarity and currency of category names, order of category listing, and overall classification system. The results of this study can be implemented for the development and improvement of portal's directory services. Users can refer to the results of this study in choosing directory services from search portals.

With the evolution of Internet technologies and the increasing variety of Internet devices, advertisements in various web services have also expanded. Interactive web services often go hand in hand with effective advertisements for a business model. We estimated statistical parameters of the interactive web server for service monitoring and advertisement-effect. In the web pages, we integrated the plugins of social networking services (SNSs) (e.g. Facebook, Twitter) and an advertisement scheme (e.g. Google AdSense) that regards social name-directory contents. Empirical data analysis and statistical results are presented with the implementation of estimations of parameters (e.g. utilization-level and serviceability) and advertisements in a social networking name-directory service (http://ktrip.net or http://한국.net). We found that estimated parameters were applicable to service monitoring of web-server as well as to synthesis of advertisement-effect in our social-web name-directory service.

In this paper, we developed those Directory Services based on the Web-Service, because Web-Service environments provide a suitable method to gather requested information in an appropriate way. The proposed architecture cooperate with other OpenLS(Open Location Service) Core Services ( Location Utility Service and Router Determin ation service) and is an interoperability one - it ident ifies those global elements of the global Web-Services network that are required in order to ensure interoperability between Web-Services. In this paper, a new architecture of Directory Service with OpenLS Core Services is proposed and tested in OpenLS Core Services environments.

This study was investigated to the geography services and geographical directories through Internet in order to develop a geographical directory. Research method was the examination of different type of geography services through internet and geographical directories on the Internet search engines. The results show principles for a geographical directory construction: use both geographical names and subject names on the initial directory screen, repeated use the names through directory hierarchy, locality use on bottom directory as a geographical name, and fit use of the number of directories.

A DF (Directory Facilitator) provides yellow pages services for other agents in agent platform. That is to say, the agents are able to register the descriptions of the services they provide for DF or inquire DF about the services other agents provide. The Current DF cannot federate with heterogeneous agent platforms. Because DF is not opened to the other DF in the heterogeneous agent platform, it is need to something about federation technology between them. Thus, we propose the database server for the federation technology among DFs. The main purpose of the database server is to provide the environment where agents can register their services and search about the services that other agents on the heterogeneous platform provide.

The most widely used information searching method in the current internet environment is the keyword-based one, which has certain limitations in terms of precision and recall. Most major internet portals provide directory-based searching as a means to complement these limitations. However, that they adopt different classification schemes brings significant inconvenience to the users, and it consequently suggests a need to develop mapping gateway to provide cross-portal, or cross-directory information searching. In this context, this study attempts to develop a prototype system of intermediary gateway for integrated search, using the directory services of three major portals, Naver, Yahoo and Empas, and test its performance.

Most web portals provide a web directory service which selects and classifies web sites according to their subject matter. In order to investigate the directory access behavior of general Korean web users, this study analyzes directory access logs of NAVER, a major Korean web search engine. This study suggests a methodology to classify the total sessions into six different session types. This study also discusses directory access behaviors of the NAVER users by examining the distribution of sessions according to session types, the lengths of navigation within a session, and the most frequently visited categories. It is expected that this study could contribute to the development of more effective web directory services.

Recently, biological researches are required to deal with a large scale of data. While scientists used classical experimental approaches for researches in the past, it is possible to get more sophisticated observations easily with the convergence of information technologies and biology. The study on diseases is one of the most important issues of the life science. Conventional services and databases provide users with information such as classification of diseases, symptoms, and medical treatments through the Web. However, it is hard to connect or develop them for other new services because they have independent and different criteria. It may be a factor that interferes the development of biology. In this paper, we propose integrated data structures for the disease databases. We also design and implement a novel directory system for diseases as an infrastructure for developing the new diseases services.

While the amount of information exchanged through internet has dramatically increased recently, certain inefficiencies still exist with regard to the storage, distribution, and retrieval of information. As a means of improving efficiency in accessing information, many search portals provide directory services to present organized guidance to information, based on the classification schemes. This study examines the classification activities practiced by the major search portals in Korea and makes some suggestions to improve the quality of directory services.

Connotation and unlimited growth potential as the core infrastructure to implement the u-Korea RFID/USN is emerging to lead to a future Internet that can bring a huge transformation in the industry sector. On RFID/USN increase overall social interest of our country, if the world who want to dominate the market by securing the u-Korea vision and global RFID/USN technologies IT839 depending on the policy, has been active research on the USN and USN infrastructure in the future building is completed as quickly to take advantage of the USN. USN applications will increase. Of USN middleware and necessitate USN infrastructure-based application development in order to more easily USN middleware configuration directory service is one of the core services. USN infrastructure suitable for the directory service when considering the characteristics of WSN, such as the USN components, update existing directory services and search focused on the problem and receive, this paper can overcome this directory service design and implementation discussed.
