Article
With the increasing influence of online reviews, platforms hosting those reviews have played a central role shaping the review display rendering a snippet of text readily visible, with the remainder hidden, accessible upon request. Using data from 122,438 written reviews from 62,380 reviewers for 1,874 nonchain Atlanta restaurants on TripAdvisor, o...
Article
Online reviews remain a reliable source for customers when making purchase decisions. Yet, the pervasiveness of fake reviews jeopardises this reliability and questions the quality of this content. In this paper, we provide empirical evidence from a major online retailer that mitigation against fakery can be successful. To that end, we proposed, tes...
Article
A firm’s success critically hinges on its strategies in selecting its portfolio of products and services. In this paper, we study how differentiation and market alignment at the offering level impact firm performance. To that end, we mine firms’ 10-K filings to characterise the portfolio of offerings through the lens of outward relatedness, inward...

The growth of online shopping has made online reviews a critical source of information for consumers. There are, however, lots of them, in the thousands and sometimes hundreds of thousands for a single product. And these reviews keep arriving persistently over time, be it the ones that rate the product highly or the ones that rate it less favorably...

Extant literature suggests that faster app evolution (in terms of changes in quality and functionality) leads to increased app success (in terms of survival and demand). This evolution-success relationship, however, does not account for users' limited capacity to assimilate the changes resulting from a continual stream of app updates. Drawing from...
Conference Paper
Online reviews remain the de-facto reliable source for customers when making purchase decisions. Paradoxically, so much ink has been spilled to demonstrate the pervasiveness of spam online reviews. In this paper, I provide preliminary evidence that what has been claimed as a systematic flaw in online review systems is nothing but a fallacy. Using a...
Presentation
Online app markets (e.g. Apple App Store) exhibit heavy customer engagement in the form of reviews that could help software developers adjust to user needs and become more competitive in crowded app markets. Using a panel dataset on 12,231 apps and document similarity methods, we develop a model that relates app success to developers’ integration o...

Numerous Web 2.0 applications collect user opinions, and other user-generated content in the form of product reviews, discussion boards, and blogs, which are often captured as unstructured data. Text mining techniques are important for analyzing users' opinions (sentiment analysis) and identifying topics of interest (semantic analysis). However, li...
Article
Reviews and product recommendations at online stores have enabled customers to readily evaluate alternative products prior to any purchase. In this context, firms generate recommendations to refer customers to a wider variety of products. They also display customer-generated online reviews to facilitate evaluation of those recommended products. Thi...
Article
Online user forums for technical support are being widely adopted by IT firms to supplement traditional customer support channels. Customers benefit from having an additional means of product support, while firms benefit by lowering the costs of supporting a large customer base. Typically these forums are populated by content generated by users, co...
Article
Online word-of-mouth information markets hosted by retailers like Amazon have matured and become well-accepted. A salient concern however is whether or not the current setup for delivering user reviews is efficient in helping prospective consumers find their product fit. A typical customer relies on the retailer to sift through the sheer amount of...
Article
Consumer generated product reviews have been found to be quite influential on consumers' purchasing decisions. However, these user-generated contents are full of inconsistent and even conflicting opinions that accumulate over time. Prior work has mainly focused on aggregated effects of reviews, such as volume and valence. These aggregated metrics d...

This involved development and application of a three-step Hydro-Spatial Analytical Hierarchy Process (AHP). First ArcGIS was used to pr...
