Experiencing clothes behind a computer screen

Simply everything can be bought online nowadays. From mass production products to specific niche products. However, about a third of all online transactions are returned (1). Buying online can result in certain disadvantages compared to buying in an actual store, one of which is the impossibility to physically hold the product, which can in the case of online clothing retailers, result in product returns. E-commerce clothing retailers like Zalando and Wehkamp.nl use a lot of different kind of recommendations to help the customers make satisfactory choices.

When buying clothes online, a customer can not try the article behind his/her computer screen. A customer will not know if the fabric is what the customer wants or how the product will actually look when he/she wears it. Does it look fancy? Slobby? Casual? Formal? And most of all, a customer will never be sure if the clothing actually fits unless he/she tries it on. This disadvantage has to do with the fact that clothing is an experience product characterized by the attributes that need to be experienced before the purchase, like taste, softness or fit (2). According to Xiao and Benbasat (2007), the use of recommendation agents influences the choice of users to a greater extent in the case of these products. What kind of recommendation agents do Zalando and Wehkamp.nl actually have to help customers choose? Continue reading Experiencing clothes behind a computer screen

His chances fall even lower if we consider that there is no reason why both partners should be in the same age range.

Recommendation system at Netflix

Netflix was initially an American company in the business of DVD’s rental and was launched in 1997 and headquartered in California. Its initial core business was renting and mailing DVD’s to their clients. They launched their own website in the same year and developed several new rental models such as the online rental model and the monthly subscription model. At that moment, they had already developed video recommendation systems based on the experience of their customers that they cautiously recorded. For instance, they implemented systems for the clients to express concern about movies and to create movies’ ranking.

However, the market significantly changed over the last ten years with the development of the digital movies at the expense of the physical DVD’s. As a result the market was progressively moving away from the physical DVD’s to a more digital business based market. Netflix has subsequently responded to this trend and has changed dramatically over the last ten years. Continue reading Recommendation system at Netflix
