Collaborative filtering is one of the popular techniques for personalized recommendation in e-commerce. In collaborative filtering, user profiles are usually managed per product category in order to reduce data sparsity. Product diversification of Internet storefronts and multiple product category sales of e-commerce portals require cross-product category usage of user profiles in order to overcome the cold start problem of collaborative filtering. In this paper, we study the feasibility of cross-product category usage of user profiles, and suggest a method to improve recommendation performance of cross-product category user profiling. First, we investigate whether user profiles on a product category can be used to recommend products in other product categories. Furthermore, a way of utilizing user profiles selectively is suggested to increase recommendation performance of cross-product category user profiling. The feasibility of cross-product category user profiling and the usefulness of the proposed method are tested with real click stream data of an Internet storefront which sells multiple product categories including books, music CDs, and DVDs. The experiment results show that user profiles on a product category can be used to recommend products in other product categories. Also, the selective usage of user profiles based on correlations between subcategories of two product categories provides better performance than the whole usage of user profiles.

The main purpose of this study was to compare the characteristics of male innovators and of male opinion leaders across product categories in terms of personality, attitudes, social participation, media usage patterns and demographic aspects. Six product categories such as clothing, cosmetics, small electronic appliances, medium-large electronic appliances, interior supplies and sports-leisure goods was used. A valid and reliable self-report scale was used to measure innovativeness and opinion leadership for 423 male adults living in social area Analyses showed that venturesomeness is the most common characteristics between innovators and opinion leaders across product categories. Innovators showed higher tendency of narcissism while opinion leadership showed higher cosmopolitainsm. Common charateristics of innovators and of opininion leaders of both clothing and cosmetics are cosmopolitanism, narcissism, exhibitionism, venturesomeness. The degrees of social participation and media usage patterns were different according to product categories for both innovators and opinion leaders. The implications of these findings for diffusion theory and merchandising were discussed.

Product involvement is an important factor in consumer evaluation of co-branding. However, academic discussions over this factor have largely been neglected. This paper bridges this gap and investigates how product involvement moderates the strength of the reciprocal effect on each brand partner. We validate two theory-driven propositions by using a theoretical modeling approach. Proposition 1 explains that the negative reciprocal effect on partnering brands is stronger in the scenario of higher-involved categories than in lower-involved categories. Proposition 2 argues that the positive reciprocal effect on partnering brands can be more significant in the case of lower-involved categories than in higher-involved categories. To the best of our knowledge, we are the first to explore the influence of product involvement on reciprocal effects in the scenario of a moderately-incongruent co-branding alliance.

인터넷기술의 발달과 소비자의 인터넷 사용 증가로 온라인에서 팔랄 수 있는 제품군은 확장되고 있다. 흥미로운 문제는 어떤 제품군이 온라인에서 판매될 가능성이 있는가에 대한 문제보다, 제품군에 대한 브랜드 역할이 주요한 역할을 할 때, 온라인 판매 가능성이 있는가에 대한 문제이다. 특히, 중소기업제품은 대기업 제품과 달리 오프라인 유통점포에서의 취급도도 낮고, 브랜드 인지도도 떨어지고, 가격대비 품질에 대한 소비자들의 지각에서도 많은 편차가 존재하고, 구매위험도 많이 느낄 가능성도 높다. 온라인 쇼핑은 유통력 및 브랜드력이 상대적으로 약한 중소기업들에게는 기회가 될 가능성이 높으므로, 중소기업제품군의 온라인 판매가능성의 적합성율 평가하는 것은 중요하다. SEC골격 은 어떤 제품군이 온라인에서 판매될 가능성이 높은가에 대한 연구를 위해 이용되어졌고, FCB골격은 관여도와 이성/감성적 측면을 고려하여 제품군을 구분하는데 사용되어져왔다. 특히 SEC와 FCB골격과 관련된 문제이지만, 고려되지 않았던 측면이 브랜드 역할이라고 할 수 있다. 제품군의 인터넷 판매가능성을 조사하기 위해서는 SEC골격 과 FCB골격뿐만 아니라 인터넷 쇼핑의 장단점과 브랜드의 역할을 통합하는 것이 필요하다. 이 논문에서는 SEC와 FCB등의 이론적 골격과 주요요인들을 통합하는 접근 방법을 토대로 이론적인 골격을 만들고 이를 바탕으로 실증적 분석을 실시함으로써 제품군들의 온라인판매 적합성을 조사한다. 총 17개 제품군에 대한 온라인 판매 적합성에 대한 실증조사는 SEC와 FCB골격, 온라인 쇼핑의 장단점, 브랜드 관련 요인들이 전체적으로 연관되어 있음을 보여준다. 기존의 연구처럼 제품군의 특성에 따른 SEC와 온라인 판매적합성은 아주 분명하게 드러나는 것은 아니므로 독립된 골격에서 보다, 상호 의존된 골격 내에서 제품군의 구매의도 및 온라인 판매 적합성을 고려한다. 즉 제품군을 통합된 골격 내에서 정의한 후에 중소기업 제품군의 구매의도 및 온라인 적합성을 평가하는 것이 필요함을 보여준다.

The study aims to investigate the process employed by companies to intentionally create market categories through implementation of product strategy. Much of the research on market category formation focuses on the spontaneous emergence of market categories, with a few studies focusing on the intentional creation of market categories. In the course of this study, I therefore sought to understand the logic by which companies intentionally create market categories, by treating the process through which market categories are formed as a sensemaking process, and by treating the behavior of a company intentionally forming a market category as an effort to manage this sensemaking process. In empirical study, we conducted an exploratory case analysis through content analysis of company press releases and consumer reviews. It is possible that market categories can be formed or changed if the way in which they are shared among market participants can be changed. In this study, we identified two sense-giving activities for the creation of market categories by firms as follows: (1) reorganizing market categories that flat-panel TV manufacturers in the North American market have attempted to form into subcategories of smart TVs, and (2) connecting them to surrounding categories through strategic labeling to establish new categories.

This research explores consumer preferences for materials in different clothing product categories, using web-crawling and text mining techniques. Specifically, the study focuses on the material-related terms found in consumer reviews across three distinct product categories: functional clothing, formal shirts, and knit sweaters. Top-selling products within each category were identified on the Naver Shopping website based on the volume of reviews, and the four most-reviewed products were selected. Six hundred reviews per product were analyzed using the Textom big-data analysis software to determine the frequency of material-related mentions and word associations. The analysis utilized two comparative metrics: product category and usage duration. Our findings reveal notable variations in the material preferences mentioned by consumers across different product categories. The study suggests a need to re-evaluate existing standardized review criteria to better reflect consumer interests specific to each product category. Additionally, an increase in material-related terms in reviews over one month indicates the potential importance of extending the duration of product reviews to enhance the accuracy of information that reflects longer-term consumer experiences with material quality.

'어떤 제품들이 인터넷에서 잘 팔릴 것인가?' 이를 정확히 이해하기 위해서는 인터넷 쇼핑에서 뿐만 아니라, 오프라인 쇼핑에서의 소비자들의 쇼핑 목적, 온라인에 대한 인식 및 지식, 쇼핑에 대한 선호 등에 대한 이해가 필요하다. 이 논문에서는 인터넷 쇼핑과 오프라인 쇼핑 성장들 통합하여 소비자들을 분류하고, 각 집단 소비자 간에 제품군에 따라서 구매장소(온라인 vs, 오프라인), 가격에 대한 강조(가격 vs, 비가격)에 따라 차이가 나타난 것인가를 살펴보았다. 즉 어떤 유형의 소비자들이 인터넷에서 어떤 유형의 제품군에 대하여 구매를 고려하고 있는지, 그리고 그 이유는 무엇인가를 가격 및 비가격 요인을 중심으로 조사하였다. 실증분석 결과에 의하면 인터넷 쇼핑뿐만 아니라 오프라인 쇼핑의 소비자 인식 및 행동을 반영할 때에 소비자들의 온라인에 대한 전반적 선호도 및 제품별 유통채널 의존도가 다른 것으로 나타난다. 또한, 소비자 제품군을 고려하여 보면 '온라인에 대한 혜택요인을 더욱 더 크게 느끼는 소비자들의 경우에는 온라인에서 구매하려는 제품군의 수가 크다' 또는 '온라인에 대한 위험요인을 더욱 더 크게 느끼는 소비자들의 경우에는 인터넷에서 구매하려는 제품군의 수가 작다'를 간접적으로 보여주었다.

Since the emissions composition from the household products have potentially been associated with health risks for building occupants, the chemical composition emitted from the products should be surveyed. The current study identified the emission composition for 42 liquid household products, using a purge-and-trap method. This evaluation was done by classifying the household products into five product classes (deodorizers, household cleaners, color removers, pesticides, and polishes). Nineteen compounds were chosen on the basis of selection criteria. The quality control program for purge-and-trap and analytical systems included tests of laboratory blank Tenax traps and blank water samples, and the determination of calibration equation, measurement precision, method detection limit (MDL), and recovery. The number of chemicals varied according to the product categories, ranging from 4 for the product category of bleaches to 12 for the product categories of air fresheners and nail color removers. For all product categories, the emission composition and concentrations varied broadly according to product. It is noteworthy that most household products emit limonene: 19 of 25 cleaning products; 5 of 6 deodorizers; 1 of 3 pesticides; 3 of 3 color removers; and 4 of 5 polishes. It was suggested that the use of household products sold in Korea could elevate the formation of secondary toxic pollutants in indoor environments, by the reaction of limonene with ozone, which entered indoor environments or might be generated by indoor sources such as electronic air cleaning devices and copying machines.

This study analyzed the content of special selling events in internet shopping malls to establish academic standards for special selling events as tools for sales promotions and to suggest systematic guidelines for marketers designing special selling events. Based on a content analysis, the titles of special selling events from four internet shopping malls selling women's apparel were analyzed. A total of 692 titles were analyzed. The results are as follow. First, the contents categories of special selling events could be classified into two groups such as 'theme' and 'tool'. Season, product characteristics, style, advice/information, brand, annual/social events, and marketing events were the main content categories that came under the 'theme' group; in addition, the price benefit, free offers, product mix, and marketing technique were the main content categories that came under the 'tool' group. Each main content category was subdivided into several segment content categories. Second, most of the titles were composed of more than two segment content categories that involved various information and benefits; however, the portion of titles composed of only theme related content categories or only tool related content categories was substantial. Furthermore, the theme related content categories were more than the tool related content categories. Third, the usage frequencies of the contents categories were analyzed. The upcoming season, single brand, sale/discount, item/material/color, special price/lowest price, and period/time/quantity limits were the segment content categories that held a high rank. Forth, most of the factors that evoked the unplanned purchases of consumers were related to the content categories of special sale events.
