Importance and usage of the recommender system increases with the increase of information. The accuracy of the system recommendation primarily depends on the data. There is a problem in recommender systems, known as cold start problem. The lack of data about new products and users causes the cold start problem, and the system will not be able to give correct recommendation. This paper deals with cold start problem by comparing product specification and the review of the resembled products. The user, who likes the resembled product of the new one has more probability of taking interest in the new product as well. However, if a user disagreed with resembled product due to some reasons which the user mentioned in the reviews. The new product overcomes that issue, so the user will greatly accept the new product. Therefore, the system needs to recommend new product to those users as well, in this way the cold start problem will get resolved.

IT 기술이 발전함에 따라 네트워크를 통해 방대한 양의 정보가 이동하고 있다. 인터넷을 사용하는 사용자들은 올바른 사용으로 유용한 정보를 획득할 수 있으나, 올바르지 않은 사용을 하는 공격자는 악의적인 목적으로 사용하기 위해 타인의 개인 정보를 노출시키고 유포하여 다양한 피해를 발생시키고 있다. 이를 해결하기 위하여 다양한 정보보호제품이 개발되고 있다. 안전한 정보보호제품을 개발하기 위해서는 개발 과정부터 보안이 필요하며, 안전한 제품을 보증하기 위하여 제품 평가 및 보안 모듈에 대한 평가 제도들이 사용되고 있다. 본 논문에서는 정보보호제품이 안전하게 개발될 수 있도록 기존 정보보호제품 인증 제도뿐만 아니라, 정보보호 기능을 제공하지 않는 제품을 개발할 때 시행되고 있는 다양한 인증 제도까지 포함하여 연구함으로써, 더욱 안전하고 견고한 제품 개발 및 보증 방안을 제안한다.

The oversea export of agricultural-product about item and quantity has not increased recently; especially the fresh-product has a tough issue because of period of production, price large fluctuations, customs clearance, quarantine, and uncertainty about actual locality, we need the information based construction to exchange information quickly about whole range of export and to focus capacity of participation subject for increasing the export. In this study we design the agricultural-product transaction information system based on crowdsourcing to transact the agricultural-product and the information of influencing benefit directly, and the information offering about export-procedure from participation of customs clearance, finance, distribution, buyer, and producer's guild, etc. We expect the producer's guild about agriculture that has not participate the trade to be able to export the agricultural-product and the stabilization of price to transact the product of collapsed or boomed through the agricultural-product information system based on crowdsourcing.

As personalized customer services create a society that emphasizes the personality of an individual, the number of product reviews and quantity of user data generated by users on the internet in mobile shopping apps and sites are increasing. Such product review data are classified as unstructured data. Unstructured data have the potential to be transformed into information that companies and users can employ, using appropriate processing and analyses. However, existing systems do not reflect the detailed information they collect, such as user characteristics, purchase preference, or purchase priority while analyzing review data. Thus, it is challenging to provide customized recommendations for various users. Therefore, in this study, we have developed a product recommendation system that takes into account the user's priority, which they select, when searching for and purchasing a product. The recommendation system then displays the results to the user by processing and analyzing their preferences. Since the user's preference is considered, the user can obtain results that are more relevant.

Purpose: This study is addressing the establishment of the knowledge information system supplying the quality management of weapon system. It is going to support the continuous quality management through the linkages and integration between the product structure and the quality information. Methods: The interrelated relationship of the product structure information and quality information of weapon system would be expressed explicitly by taking advantage of the ontology concept. The quality information of distributed systems would be integrated through the SOA(Service Oriented Architecture)-based Web services. After defining the inference rules, which could be utilized in the quality management, in the constructed knowledge information system, the quality information would be inferred through the queries. Results: By building the integrated quality information knowledge system through the ontology and SOA, the connectivity between the product structures and dispersed quality information was enhanced. The utility and applicability of this study were checked up through the inferences on the products and quality information by using the information built by the semantic relationship of facts. Conclusion: We established the knowledge and information system as a systematic approach to support the quality management of weapon system. This is not affected by the organizations and systems, and it seems that it could be utilized across the quality management as the efficient knowledge sharing architecture supporting the quality management of weapon systems in the aspect of the product integration.

최근, 제조기업들의 일반적인 추세는 제품들이 보다 더 고객화 되어가고 있으며, 제품수영주기가 짧아지고 있다는 것이다. 이러한 제조기업들에 있어서, 고객들은 종종 자신들이 주문한 제품의 제조과정 동안에 자신들의 요구사항들을 지속적으로 반영하기를 원하며, 또한 자신들의 요구사항들이 충족된 제품을 인도받기를 원한다. 이러한 기업 환경을 고객지향 수주생산 환경이라고 한다. 본 논문에서는 고객지향 수주생산 환경에 적합한 제품정보 통합시스템 (PDIS: Product Data Integration System) 구축을 위한 정보시스템 개발 방법론을 정립하고, 또한 정립된 방법론을 이용하여 대표적인 고객지향산 제품인 'H'중공업의 선박엔진 제품을 대상으로 PDIS 구축 사례를 제시하였다. 현재 구축된 PDIS는 현업에서 성공적으로 운영되고 있다. 그 결과, 납기시간이 단축되고, 고객과의 관계가 향상되었으며, 그리고 제품수명주기 동안 기업 내 부서간의 업무 협력이 향상되었다.

We developed Intelligent Product Search Agent based on SWRL, and this agent can search product information with knowledge(facts and rules) on the web, implement price comparison for searched products considering delivery rates. Existing keyword based product search engines is poor at searching intent products though a user has already prefect knowledge about intent produces. Furthermore if a user has insufficient knowledge, it is impossible to implement search. Also, existing price comparison shopping mall gives users comparison service considering total price(product prices, taxes, delivery rates), this service is valid to single product and has limitations of system expansion and up-dating because of not rule base but programming base. If there is appropriate knowledge on the Semantic web and this makes product information retrieval possible, above problems can be solved clearly. In this research, we developed Intelligent Product Search Agent based on SWRL that can search product information efficiently by making agent to handle facts and rules by itself.

최근 가습기살균제 사건을 비롯하여 휴대폰, 유아용 기저귀 등 생활용품의 안전사고가 빈번히 발생하고 있다. 이러한 사고로부터 소비자를 보호하기 위해서는 제품 안전관리가 필요하며, 제품의 안전성 정도를 평가할 수 있는 제품 리스크 평가 도구가 필요하다. 본 논문은 한국소비자원의 제품 사고관련 위해정보를 바탕으로 제품 리스크를 평가할 수 있는 시스템인 RAS(Risk Assessment System)를 구축하였다. RAS는 사고관련 정보를 분석하는 위해정보 분석시스템과 이 시스템으로부터 도출된 정보를 활용하여 리스크를 평가하는 리스크 평가시스템으로 구성되어 있다. 리스크 평가과정에서 제품 리스크에 영향을 미치는 인과관계를 반영한 베이지안 네트워크 기반의 확률적 기법을 적용하였다. RAS를 사용하여 어린이 제품 33품목에 대해 평가를 실시했으며 EU RAPEX의 RAG의 평가결과와 비교해 보았다. 그 결과 본 연구의 RAS의 결과는 전반적으로 EU RAPEX RAG의 평가 결과에 비해 낮은 수준을 보임을 알 수 있었다. 추후과제로는 사고영향척도 입력값의 주관성 저감, 위해정보 분석시스템과 리스크 평가시스템의 연동 등을 들 수 있다.

An efficient management of product information is critical to the enhancement of corporate competitiveness. Product information is often distributed in term of organization, geography, and time. With the rapid increase in the use of Internet or its associated Web and intranets, it has been accelerating to integrate the distributed information. In this research, a Distributed, Open, Intelligent Product data Management system, namely DOI-PDM, is developed. This system deals with product information following the STEP standard, and its operation is controlled by a Web-based workflow management system. CORBA is employed to ensure interoperability among distributed objects. It is intended to achieve openness by using various standards, such s STEP, KQML, SGML, and WfMC specifications. One major difficulty in managing it needs also be properly modified according to the dynamics. It however is very hard to have a prior anticipation to the dynamics. It however is very hard to have a prior anticipation to the modification requirements in practice. We introduce a process adaptation model and a use of intelligent agent technology. An agent is delegated to modify process definitions during run-time. A method of agent implementation and a proper communication scheme among te agents are proposed. Also developed in this research is a STEP-based content search system which can co-work with the agents by providing relevant product information that the agents require.
