Yelp’S Review Filtering Algorithm, Yao Yao, Ivelin Angelov, Jack Rasmus-Vorrath, Mooyoung Lee, Daniel W. Engels Aug 2018

Yelp’S Review Filtering Algorithm, Yao Yao, Ivelin Angelov, Jack Rasmus-Vorrath, Mooyoung Lee, Daniel W. Engels

SMU Data Science Review

In this paper, we present an analysis of features influencing Yelp's proprietary review filtering algorithm. Classifying or misclassifying reviews as recommended or non-recommended affects average ratings, consumer decisions, and ultimately, business revenue. Our analysis involves systematically sampling and scraping Yelp restaurant reviews. Features are extracted from review metadata and engineered from metrics and scores generated using text classifiers and sentiment analysis. The coefficients of a multivariate logistic regression model were interpreted as quantifications of the relative importance of features in classifying reviews as recommended or non-recommended. The model classified review recommendations with an accuracy of 78%. We found that ...

Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus Dec 2017

Insight Provenance For Spatiotemporal Visual Analytics: Theory, Review, And Guidelines, Andreas Hall, Paula Ahonen-Rainio, Kirsi Virrantaus

Journal of Spatial Information Science

Research on provenance, which focuses on different ways to describe and record the history of changes and advances made throughout an analysis process, is an integral part of visual analytics. This paper focuses on providing the provenance of insight and rationale through visualizations while emphasizing, first, that this entails a profound understanding of human cognition and reasoning and that, second, the special nature of spatiotemporal data needs to be acknowledged in this process. A recently proposed human reasoning framework for spatiotemporal analysis, and four guidelines for the creation of visualizations that provide the provenance of insight and rationale published in ...

Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili Jan 2016

Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili

Electrical & Computer Engineering and Computer Science Faculty Publications

Hash functions are established and well-known in digital forensics, where they are commonly used for proving integrity and file identification (i.e., hash all files on a seized device and compare the fingerprints against a reference database). However, with respect to the latter operation, an active adversary can easily overcome this approach because traditional hashes are designed to be sensitive to altering an input; output will significantly change if a single bit is flipped. Therefore, researchers developed approximate matching, which is a rather new, less prominent area but was conceived as a more robust counterpart to traditional hashing. Since the ...

Price, Perceived Value And Customer Satisfaction: A Text-Based Econometric Analysis Of Yelp! Reviews, Eleanor A. Dwyer Jan 2015

Price, Perceived Value And Customer Satisfaction: A Text-Based Econometric Analysis Of Yelp! Reviews, Eleanor A. Dwyer

Scripps Senior Theses

We examine the antecedents of customer satisfaction in the restaurant sector, paying particular attention to perceived value and price level. Using Latent Dirichlet Allocation, we extract latent topics from the text of Yelp! reviews, then analyze the relationship between these topics and satisfaction, measured as the difference between review rating and user average review rating.

Smart Nanotextiles: A Review Of Materials And Applications, Gordon G. Wallace, Danilo De Rossi, Yanzhe Wu, King-Tong Lau, Shirley Coyle, Dermot Diamond Mar 2013

Smart Nanotextiles: A Review Of Materials And Applications, Gordon G. Wallace, Danilo De Rossi, Yanzhe Wu, King-Tong Lau, Shirley Coyle, Dermot Diamond

Gordon Wallace

The development of smart nanotextiles has the potential to revolutionize the functionality of our clothing and the fabrics in our surroundings. Nanoscale manipulation results in new functionalities for intelligent textiles, including self-cleaning, sensing, actuating, and communicating. This is made possible by such developments as new materials, fibers, and finishings; inherently conducting polymers; carbon nanotubes; and antimicrobial nanocoatings. These additional functionalities have numerous applications, encompassing healthcare, sports, military applications, and fashion. The wearer and the surrounding environment may be monitored in an innocuous manner, giving continuous updates of individual health status or environmental hazards. More generally, smart textiles become a critical ...


Nonprofit Funding Agencies’ Review Of Grant Recipients, Siobain Mcilvain Nov 2012

Nonprofit Funding Agencies’ Review Of Grant Recipients, Siobain Mcilvain

Honors Theses - Providence Campus

Nonprofits need to be just as responsible as public corporations. Nonprofit funding agencies have the responsibility for evaluating the organizations they fund to make sure that they are operating with high integrity, maintaining strong internal controls, remaining financially stable, and overall being good stewards of the funds received. This paper will explain the criteria that a funding agency should follow in order to affect this process, as well as how a recipient nonprofit will benefit from following the criteria.


Book Review - Women In Leadership: Contextual Dynamics And Boundaries, Christine Eriksen Jan 2012

Book Review - Women In Leadership: Contextual Dynamics And Boundaries, Christine Eriksen

Faculty of Science - Papers (Archive)

Leadership scenarios and paradoxes - past, present and future - form the basis of Karin Klenke's analysis of women in leadership. The book sets out to explore the paradoxical nature of women's leadership in male-dominated contexts, paradoxes women leaders are confronted with, as well as the paradox of change versus the persistence of the status quo. Contexts with a 'paradoxical nature'- temporally and spatially - are at the forefront. These 'contexts' for women's leadership range from remarkable female leaders, today and historically, in politics, organisational structures, information technology (IT), the media, sports, the military, religion and spirituality, science, higher education ...

Sustainability Potential Of Suburban Gardens: Review And New Directions, Sumita Ghosh Jan 2010

Sustainability Potential Of Suburban Gardens: Review And New Directions, Sumita Ghosh

Faculty of Science - Papers (Archive)

Gardens, as important elements of Australian suburban residential environments, could have significant sustainability potential similar to that of dwellings. Research to identify the cumulative (social, cultural, environmental and ecological) sustainability values of suburban domestic gardens has been very limited. Australian suburbs are likely to retain their typical characteristics for a considerable period of time as their rapid intensification is not likely. Therefore, it is immensely important to understand the role and performance of the suburban garden in this discourse. This article reviews the sustainability potential of domestic gardens and their links to suburban forms, sustainable design, social processes, and environmental ...

Eoarchaean crust in West Greenland (the Itsaq Gneiss Complex, 3870-3600 Ma) is >80% by volume orthogneisses derived from plutonic tonalite-trondhjemite-granodiorite (TTG) suites,3850, c. 3810 and c. 3710 Mahave some compositional similarities to modern island arc basalts (IAB), suggesting their origin by hydrous fluxing of a suprasubduction-zone upper mantle wedge. Most of the Eoarchaean tonalites match in composition high-silica, low-magnesian adakites, whose petrogenesis is dominated by partial melting of garnetiferous mafic rocks at high pressure. However, associated with the tonalites are volumetrically minor more magnesian quartz diorites, whose genesis probably involved melting of depleted mantle to which some slab-derived component ...
