2.0 시대에 도래하면서 웹에 대한 새로운 패러다임이 생성되었다. 이러한 웹 2.0의 주요 기술은 OpenAPI인데, OpenAPI는 간단한 프로토콜로 정의되어 사용되기 때문에 많은 사용자들이 손쉽게 서비스를 만들 수 있는 장점이 있다. 하지만 빠르게 증가하는 OpenAPI를 효과적으로 검색할 수 있는 여전히 연구중이다. 본 논문은 이러한 OpenAPI에 대해 키워드 기반 검색보다 한단계 발전한 시맨틱 기반의 검색을 제공하기 위해 관련 표준 및 기술에 대해 설명하였다. 이러한 시맨틱을 활용한 OpenAPI의 검색기법은 OpenAPI를 통해 많이 사용되는 매쉬업(Mashup)을 위한 서비스 검색에도 활용될 수 있다.

As Web services cover more and more IT area and the number of their implementation cases increase rapidly, most associates have begun to consider the quality of Web services. They require the framework that helps to evaluate and measure the quality of Web services. OASIS WSQM(Web Services Quality Model) technical committee already published Web Services Quality Model specification version 2.0 in 2006. However, it has been described in conceptually. That is, it contains the model view, classification of quality factors, some activities and associates. So, we need Web services quality description language (WSQDL) shaped in XML. To describe WSQDL schema, we need a new paradigm to represent the Web services quality factors consistently and interoperably. For this we provide the new concept of quality chain in this paper.

Diverse research topics relating to Social Network Services (SNS) such as, social affective factors in relationships among internet users, social capital value of SNS, comparing attributes why users are intending to participate in SNS, user's lifestyle and their preferences, and the exploratory seeking potential of SNS as a social capital need to be focused on. However, these researches that have been undertaken only consider facts at a particular period of the changing computing environment. In accordance with this indispensability, the integrated view on what technical, social and business characteristics and attributes need to be acknowledged. The purpose of this study is to analyze the evolving attributes and characteristics of SNS from Web 1.0 to Mobile web 2.0 through the Web 2.0 and Mobile 1.0 period. Based on the relevant literature, the attributes that drive the changing technological, social and business aspects of SNS have been developed and analyzed. This exploratory study analyzed major attributes and relationships between SNS and users by changing the paradigms which represented each period. It classified and chronicled each period by representing paradigms and deducted the attributes by considering three aspects such as technological, social and business administration. The major findings of this study are, firstly, the web based computing environment has been changed into the platform attribute for users in the aspect of technology. Users can only read, listen and view information through the web site in the early stages, but now it is possible that users can create, modify and distribute all kinds of information. Secondly, the few knowledge producers of web services have been changed into a collective intelligence by groups of people in the aspect of society. Information authority has been distributed and there is no limit to its spread. Many businesses recognized the potential of the SNS and they are considering how to utilize these advantages toward channel of promotion and marketing. Thirdly, the conventional marketing channel has been changed into oral transmission by using SNS. The market of innovative mobile technology such as smart phones, which provide convenience and access-ability toward customers, has been enlarged. New opportunities to build friendly relationship between business and customers as a new marketing chance have been created. Finally, the role of the consumer has been changed into the leading role of a prosumer. Users can create, modify and distribute information, and are performing the dual role of customer and producer.

The Internet is appearing a new paradigm called Web 2.0 which 'Participation', 'Sharing', 'Openness', 'Cooperation'. Web 2.0 is expanded by experts and general users and many people's ideas can solve more problems than an expert's idea. The collective intelligence is techniques that express the valuable of Web 2.0. For this reason, the collective intelligence has attracted attention because of its potential as an educational tool. The purpose of this study is to develop a PBL-based programming instruction model using collective intelligence to improve students' problem solving abilities and programming attitudes and verified its effectiveness. As a result, the developed instruction model showed significant differences in the students' problem solving abilities and programming attitudes. According to these results, these have been proved that a PBL-based programming instruction model using collective intelligence has an influence to the students' problem solving abilities and programming attitudes.

The concept of Government 2.0 is spreading rapidly in many countries and is fundamentally changing existing freedom of information system which has passively responded to information demands. This study aims at discussing possible strategies for a new freedom of information system that is based on the Government 2.0 notion which presents revolutional approaches to public sector information's creation, management, and usage. For the purpose of the study, precedence studies and researches about both freedom of information system and Government 2.0 are analyzed. Furthermore, mutual relationships between them are discussed. Through this discussion, social and economic benefits from freedom of information systems which are based on Government 2.0 are explored. As a case study, Data.gov services in the US, the UK, and Australia which are recognised as a feasible plan to set up Government 2.0 are analyzed. Their three common characteristics- revaluating public sector information's reuse, establishing exclusive agencies, and providing raw data-are discussed. Then, various mashup services which use Data.gov services' raw data are also studied. Issues related to the freedom of information system in South Korea are examined. As a result, a policy framework for establishing Government 2.0 based freedom of Information system is discussed in terms of three aspects, law, technology and organization.
