TLDR
A theory model for product search based on expected utility theory from economics is proposed, in which the top ranked products are the "best value for money" for a specific user.Abstract:
With the growing pervasiveness of the Internet, online search for products and services is constantly increasing. Most product search engines are based on adaptations of theoretical models devised for information retrieval. However, the decision mechanism that underlies the process of buying a product is different than the process of locating relevant documents or objects.We propose a theory model for product search based on expected utility theory from economics. Specifically, we propose a ranking technique in which we rank highest the products that generate the highest surplus, after the purchase. In a sense, the top ranked products are the "best value for money" for a specific user. Our approach builds on research on "demand estimation" from economics and presents a solid theoretical foundation on which further research can build on. We build algorithms that take into account consumer demographics, heterogeneity of consumer preferences, and also account for the varying price of the products. We show how to achieve this without knowing the demographics or purchasing histories of individual consumers but by using aggregate demand data. We evaluate our work, by applying the techniques on hotel search. Our extensive user studies, using more than 15,000 user-provided ranking comparisons, demonstrate an overwhelming preference for the rankings generated by our techniques, compared to a large number of existing strong state-of-the-art baselines.read more

What Web Search Behaviors Lead to Online Purchase Satisfaction?
TL;DR: In this paper , the authors examined the relationship between web information-seeking behavior and post-purchase satisfaction and found that satisfied users more frequently searched for a wider range of product-related information than dissatisfied users.

TL;DR: In this paper , an adversarial backward compatible training method with an elastic boundary constraint is proposed to improve the compatibility of two models with less negative impact on retrieval performance, which takes both compatibility and discrimination into consideration.

Dialectic: Enhancing Text Input Fields with Automatic Feedback to Improve Social Content Writing Quality.
TL;DR: Dialectic is introduced, an end-to-end extensible system that simplifies the process of creating, customizing, and deploying content-specific feedback for free-text inputs and can be used to create a feedback interface that produces an average of 14.4\% quality improvement of product review text, over 3x better than a state-of-the-art feedback system.

A simplex method for function minimization
John A. Nelder,R. Mead +1 more
TL;DR: A method is described for the minimization of a function of n variables, which depends on the comparison of function values at the (n 41) vertices of a general simplex, followed by the replacement of the vertex with the highest value by another point.

Hedonic Prices and Implicit Markets: Product Differentiation in Pure Competition
TL;DR: In this article, a theory of hedonic prices is formulated as a problem in the economics of spatial equilibrium in which the entire set of implicit prices guides both consumer and producer locational decisions in characteristics space.
