1 - Human Intelligence In Keyword Query Formulation: Comparing

The Recall Performance Of Computer- And Human-generated

Smoke Word Lists

Are humans better at producing safety concern keyword searches than

computers? 72 subjects annotated 263 reviews of over-the-counter medicines,

half of which contained known safety concerns. Subjects then compiled a list of

words and phrases that might be effective filter terms in finding reviews with

safety concerns. Subjects then collaborated in groups of 2, 3 or 4 to assemble a

group list. Lists were scored on how many of the known safety concerns they

were able to recall in a separate test set. Preliminary results indicate that human-

generated lists frequently outperform computer-generated lists.

2 - Let’S Not Get Too Sentimental: A Critical Analysis Of Sentiment

Analysis For Quality Surveillance

Our study will be beneficial for quality management (QM) professionals analyzing

unstructured user-generated-content in social media. The goal is to determine

whether and to what extent negative sentiment and defect existence are

associated, in different products across multiple industries. With product defects

being expensive, this paper could help manufacturers more rapidly discover

defects. This paper aims to assess which sentiment and non-sentiment scoring

methods are most effective at finding product defects in each industry, and which

methods generalize well across industries.

3 - Online Reviews To Revenue: Contributory Factors And

Moderating Effects In The Airline Industry

In this study, online reviews of airlines are examined with respect to company

revenue. Though previous studies have examined online reviews’ effect on

product sales, the relationship has not been elicited in service industries, including

the airline industry. Using passengers’ reviews of the 7 airline groups with the

highest revenue we consider the impact of these reviews on the quarterly

revenue of each of these companies. Compared with other major industries, the

airline industry has the highest defect rate in their online reviews. Our findings

suggest that online reviews do have an impact on company revenue, however

this impact is dampened by offline maneuvers.

4 - Identifying Product Defects From User Complaints:

A Probabilistic Defect Model

Discovering potential product defects from large amounts of user complaints is a

challenging task. In this research, we develop a probabilistic defect model (PDM)

that identifies the most critical product issues and corresponding product

attributes (e.g., product model-year, defective components, symptoms, etc.),

simultaneously. We conduct comprehensive evaluations to ensure the quality of

discovered information. Our research has significant managerial implications for

managers, manufacturers, and policy makers.

Data Analytics in Renewable Energy

1 - Exploratory Data Analytics For Temporal Lighting Energy Usage In

Commercial Buildings

Lighting energy usage accounts for a major proportion of building energy

consumption. A better understanding of lighting energy data will facilitate

building energy management. Conventional studies mainly focused on aggregate-

level energy usage, ignoring the temporal usage patterns featured in stochasticity,

nonlinearity and intermittency. In this study, an exploratory data analytics

approach is proposed to extract, cluster and visualize temporal patterns of lighting

energy usage in commercial buildings. A real data study is further provided to

illustrate the proposed work and demonstrate its validity.

2 - Characterization Of Air Traffic Network Using Ads-b Data

Airspace capacity has been credited as a major factor for air traffic congestion and

flight delays. However, few studies provided measures of airspace capacity and

efficiency for a large air traffic network. This research aims at evaluating whether

airspace capacity is a significant factor in relation to recent air traffic delays in

China. We developed a novel method to characterize flow patterns in the airspace

and construct an air traffic network using cluster analysis on historical flight

trajectories. Findings will be useful in evaluating the efficiency and robustness of

an air traffic network in relation to its actual operation and management.

3 - Image-based Wind Turbine Blade Surface Crack Detection

And Analysis

A data-driven framework for automatically detecting wind turbine (WT) blade

surface cracks based on images taken by unmanned aerial vehicles (UAVs) is

proposed in this paper. Haar-like features are applied to depict crack regions and

train a cascading classifier. The computational results demonstrate that the

proposed framework can successfully provide the number of cracks and locate

them in original images.

1 - An Economic Analysis Of Customer Codesign

A key barrier to companies successfully engaging customers in the design of new

products is customers fearing that they will be forced to pay much more for the

custom products they help design. We show how a firm can motivate its

customers to engage in co-design through its product line choices. The effect of

market and firm characteristics on the value of engaging customers in the co-

design process is also examined. In addition, we analyze the effects of (a)

information asymmetry about the firm’s co-design capability, and (b) competition,

on the firm’s decisions regarding co-design.

2 - Allocating Customer Control In Service Processes

In most services customers actively participate in the service deliver process. In

practice we observe services that require varying degrees of customer

involvement. Motivated by this, we develop an analytical model to determine

which parts of a service process should be performed by the service provider and

which parts should be delegated to the customers.

3 - Sourcing Innovation: Private And Public Feedback In Contests

Jurgen Mihm, Insead, Fontainebleau, France,

Contests, in which contestants compete for a prize offered by a contest holder,

have become a popular way to source innovation. Despite great interest from the

academic community, many important managerial aspects of contests have

received very little formal inquiry. The most important of these is feedback from

the contest holder to the contestants while the contest unfolds. This paper sets out

to establish a comprehensive understanding of how to give feedback in a contest

by answering the questions of when to give feedback and when not to give

feedback and which type of feedback to give, public (which all solvers can

observe) or private (which only the concerned party can observe).
