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 ...


Holistic Sludge Management Through Ozonation: A Critical Review, Galilee U. Semblante, Faisal I. Hai, Dionysios D. Dionysiou, Kensuke Fukushi, William E. Price, Long D. Nghiem Jan 2017

Holistic Sludge Management Through Ozonation: A Critical Review, Galilee U. Semblante, Faisal I. Hai, Dionysios D. Dionysiou, Kensuke Fukushi, William E. Price, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

This paper critically reviews the multidimensional benefits of ozonation in wastewater treatment plants. These benefits include sludge reduction, removal of emerging trace organic contaminants (TrOC) from wastewater and sludge, and resource recovery from sludge. Literature shows that ozonation leads to sludge solubilisation, reducing overall biomass yield. Sludge solubilisation is primarily influenced by ozone dosage, which, in turn, depends on the fraction of ozonated sludge, ozone concentration, and sludge concentration. Additionally, sludge ozonation facilitates the removal of TrOCs from wastewater. On the other hand, by inducing cell lysis, ozonation increases the chemical oxygen demand (COD) and nutrient concentration of the sludge ...

Degradation Of Pharmaceuticals And Personal Care Products By White-Rot Fungi-A Critical Review, Muhammad Bilal Asif, Faisal I. Hai, Lakhveer Singh, William E. Price, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

White-rot fungi (WRF) mediated treatment can offer an environmentally friendly platform for the removal of pharmaceuticals and personal care products (PPCPs) from wastewater. These PPCPs may have adverse impacts on aquatic organisms and even human and thus their removal during wastewater treatment is of significant interest to the water industry. Whole-cell WRF or their extracellular lignin modifying enzymes (LMEs) have been reported to efficiently degrade PPCPs that are persistent to conventional activated sludge process. WRF mediated treatment of PPCPs depends on a number of factors including physicochemical properties of PPCPs (e.g., hydrophobicity and chemical structure) and wastewater matrix (e ...

Fundamentals And Applications Of Inertial Microfluidics: A Review, Jun Zhang, Sheng Yan, Dan Yuan, Gursel Alici, Nam-Trung Nguyen, Majid Ebrahimi Warkiani, Weihua Li Jan 2016

Fundamentals And Applications Of Inertial Microfluidics: A Review, Jun Zhang, Sheng Yan, Dan Yuan, Gursel Alici, Nam-Trung Nguyen, Majid Ebrahimi Warkiani, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

In the last decade, inertial microfluidics has attracted significant attention and a wide variety of channel designs that focus, concentrate and separate particles and fluids have been demonstrated. In contrast to conventional microfluidic technologies, where fluid inertia is negligible and flow remains almost within the Stokes flow region with very low Reynolds number (Re < 1), inertial microfluidics works in the intermediate Reynolds number range (~1 < Re < ~100) between Stokes and turbulent regimes. In this intermediate range, both inertia and fluid viscosity are finite and bring about several intriguing effects that form the basis of inertial microfluidics including (i) inertial migration and (ii) secondary flow. Due to the superior features of high-throughput, simplicity, precise manipulation and low cost, inertial microfluidics is a very promising candidate for cellular sample processing, especially for samples with low abundant targets. In this review, we first discuss the fundamental kinematics of particles in microchannels to familiarise readers with the mechanisms and underlying physics in inertial microfluidic systems. We then present a comprehensive review of recent developments and key applications of inertial microfluidic systems according to their microchannel structures. Finally, we discuss the perspective of employing fluid inertia in microfluidics for particle manipulation. Due to the superior benefits of inertial microfluidics, this promising technology will still be an attractive topic in the near future, with more novel designs and further applications in biology, medicine and industry on the horizon.

Introduction - A Review Of Membrane Reactors, Fausto Gallucci, Angelo Basile, Faisal Ibney Hai Sep 2015

Introduction - A Review Of Membrane Reactors, Fausto Gallucci, Angelo Basile, Faisal Ibney Hai

Faisal I Hai

In the last decades, membrane catalysis has been studied by several research and the significant progress in this field is summarized in several review articles (Armor 1998, Lin 2001, Lu 2007, Mcleary 2006, Sanchez 2002, Saracco 1994, Shu 1991). Considering a IUPAC definition (Koros 1996), a membrane reactor (MR) is a device for simultaneously performing a reaction (steam reforming, dry reforming, autothermal reforming, etc.) and a membrane-based separation in the same physical device. Therefore, the membrane not only plays the role of a separator, but also takes place in the reaction itself. The term Membrane Bioreactor (MBR), on the other ...

Effective Utilization Of Excess Energy In Standalone Hybrid Renewable Energy Systems For Improving Comfort Ability And Reducing Cost Of Energy: A Review And Analysis, M Ismail Ismail, Mahmoud Moghavvemi, T Mahlia, Kashem M. Muttaqi, S Moghavvemi

Faculty of Engineering and Information Sciences - Papers: Part A

One of the features that characterize renewable energy sources is their variability and intermittency. Intermittency covers both the predictable and unpredictable variations of their power outputs and uncertainty in the power availability. To overcome the drawback of intermittency, special design considerations should be taken into account. These additional design considerations increases the overall cost of the renewable energy systems. Adding storage system and/or backup source to the renewable sources is one of the measures used to guarantee the continuity of power supply to the loads, and therefore improve the reliability of the renewable energy systems. The operation of renewable ...

Inorganic PCMs possess higher heat storage capacities and conductivities, cheaper and readily available as well as being non-flammable, but do experience supercooling and phase segregation problems during phase change process. The review has also shown that eutectic PCMs have unique advantage since their melting points can be adjusted. In addition, they have relatively high ...


Alternative Al Production Methods: Part 1 - A Review Of Indirect Carbothermal Routes, M A. Rhamdhani, M A. Dewan, G A. Brooks, B J. Monaghan, L Prentice Sep 2014

Alternative Al Production Methods: Part 1 - A Review Of Indirect Carbothermal Routes, M A. Rhamdhani, M A. Dewan, G A. Brooks, B J. Monaghan, L Prentice

Brian Monaghan

The production of Al from its ores at present relies on the Bayer (alumina production) and the Hall- Heroult (Al production) process. The cost associated with alumina production and apparent disadvantages of the Hall-Heroult process have led to intensive research to find alternative routes for Al production. The direct carbothermal reduction process has been thoroughly investigated as an alternative technique. Another alternative includes the indirect carbothermal reduction route where alumina (or aluminous ores) is first reduced to intermediate Al compounds before reduced further to Al. The present study reviews and provides systematic thermodynamic analyses of alternative Al production routes. In ...
