Semantic-Based Approach to Supporting Opinion SummarizationChen, Yen-Ming 20 July 2006 (has links)
With the rapid expansion of e-commerce, the Web has become an excellent source for
gathering customer opinions (or so-called customer reviews). Customer reviews are
essential for merchants or product manufacturers to understand general responses of
customers on their products for product or marketing campaign improvement. In
addition, customer reviews can enable merchants better understand specific
preferences of individual customers and facilitates making effective marketing
decisions. Prior data mining research mainly concentrates on analyzing customer
demographic, attitudinal, psychographic, transactional, and behavioral data for
supporting customer relationship management and marketing decision making and did
not pay attention to the use of customer reviews as additional source for marketing
intelligence. Thus, the purpose of this research is to develop an efficient and effective
opinion summarization technique. Specifically, we will propose a semantic-based
product feature extraction technique (SPE) which aims at improving the existing
product feature extraction technique and is desired to enhance the overall opinion
summarization effectiveness.

Att minska e-handelns returgrad : Hur medietekniska lösningar kan minska andelen returer / To reduce the return rate of the e-commerce : How media technology can reduce the return rateRosberg, Tove January 2022 (has links)
Eftersom e-handeln ökar och returgraden likaså har returer blivit ett av e-handelns största miljöproblem, särskilt inom modebranschen. Detta arbete syftar därför till att undersöka vad som påverkar den höga returgraden samt hur olika medietekniska lösningar såsom produkt-information, kundrecensioner, storleksguider och virtuella provrum kan minska returgraden. I två fokusgrupper diskuterades arbetets syfte och resultatet sammanställdes sedan i en innehålls-analys. Med utgångspunkt i tidigare forskning och det empiriska materialet fördes en diskussion kring returorsaker samt medietekniska lösningar och deras potential. Både empiri och tidigare forskning vittnar om att storlek- och passformsproblem är de främsta orsakerna till retur och att medietekniska lösningar kan reducera antalet returer inom modebranschen genom att minska dessa problem. Dock behöver e-handelsföretag arbeta för att sådana lösningar ska användas i större utsträckning. / As the e-commerce is increasing so are the returns and returns have therefore become one of e-commerce biggest environmental problems, especially in the fashion industry. This study aims to investigate what influence the high return rate and how different technology solutions such as product information, customer reviews, size guides and virtual fitting rooms can decrease the return rate. In two focus groups the purpose of the study was discussed, and the result was compiled in a content analysis. Based on previous research and the empirical material a discussion was held about the causes of return as well as the media technology solutions and their potential. Both empirical material and previous research demonstrate size and fit problems as the main reasons for return and that media technology solutions can reduce the number of returns in the fashion industry. However, e-commerce companies must work for such solutions to be used to a greater extent.
