The purpose of this study is to contribute to the marketing literature and practice by describing a research methodology to identify latent dimensions of customer satisfaction in product reviews, and examining the relationship between these attributes and customer satisfaction. Previous research in product reviews has largely relied only on quantitative ratings, either stars or review score. Advanced techniques for text mining provide the opportunity to extract meaning from customer online reviews. By analyzing 51,110 online reviews for 1,610 restaurants via latent Dirichlet allocation, this study uncovers 30 latent dimensions that are determinants of customer satisfaction. Furthermore, this study developed measurements of sentiment and innovativeness as moderators of the effect of these latent attributes to satisfaction.
Purpose
The purpose of this paper is to study the relationship between changes in relative influence between marketing and R&D and new product performance (NPP). The aim is to theorize and test whether relative influence changes are beneficial for NPP.
Design/methodology/approach
An international survey was sent out to pharmaceutical companies worldwide, resulting in 106 usable questionnaires from knowledgeable senior managers. A model is estimated that relates recent and historic changes in relative influence to NPP.
Findings
There is a positive relationship between recent relative influence changes and subsequent NPP. Moreover, this paper finds that having a history of adaptation with respect to relative influence can serve organizations to build up capabilities that, in turn, strengthen the positive effects of recent relative influence changes on NPP. Finally, the paper shows that relative influence changes and integration between marketing and R&D positively affect NPP jointly.
Originality/value
A core finding, that is quite counterintuitive, is that instability with respect to relative influence changes can help organizations to become more competitive in new product development.
Purpose
The purpose of this paper is to contribute to the marketing literature and practice by examining the effect of product pricing on consumer behaviours with regard to the assertiveness and the sentiments expressed in their product reviews. In addition, the paper uses new data collection and machine learning tools that can also be extended for other research of online consumer reviewing behaviours.
Design/methodology/approach
Using web crawling techniques, a large data set was extracted from the Google Play Store. Following this, the authors created machine learning algorithms to identify topics from product reviews and to quantify assertiveness and sentiments from the review texts.
Findings
The results indicate that product pricing models affect consumer review sentiment, assertiveness and topics. Removing upfront payment obligations positively impacts the overall and pricing specific consumer sentiment and reduces assertiveness.
Research limitations/implications
The results reveal new effects of pricing models on the nature of consumer reviews of products and form a basis for future research. The study was conducted in the gaming category of the Google Play Store and the generalisability of the findings for other app segments or marketplaces should be further tested.
Originality/value
The findings can help companies that create digital products in choosing a pricing strategy for their apps. The paper is the first to investigate how pricing modes affect the nature of online reviews written by consumers.
