Young researchers care about community at Science and Technology Poster Presentation

Published on 19 April 2016

When you buy things online, you would probably look at the comments of other buyers on the products. These comments, positive or negative, tend to affect your decision on whether to add the products to your cart.

“Online customers’ reviews and comments play an important role in online transaction,” said Year Four Statistics student Zheng Jinghang. “However, people are often confused by bewildering comments which are a mixture of meaningful and pointless words.”

At the Fourth Undergraduate Science and Technology Poster Presentation on 13 April, Zheng presented his final year project “Analysis of Online Customer Comments on Midea Calorifiers”. “Aiming at the information extraction of text mining, my project focused on item segmenting, document filtering and emotional analysis of the comments on calorifiers of Midea, a Chinese electrical appliance manufacturer, on the e-commerce website jd.com,” he added.

“I collected over 40,000 comments, segmented them, and deleted meaningless components and words of the sentences. I then classified and grouped the comments that had been analysed in four areas: individual requirements, appreciations and complaints, differentiation strategy, and reasons of choosing Midea.”

Zheng concluded: “Comment classification works well in learning the features of products and services. Understanding the feedback of customers can also help Midea improve itself.”

His research was one of the 49 projects on display that were prepared by the students of all the six programmes of the Division of Science and Technology (DST).

Another student, Cai Siying, from the Food Science and Technology Programme investigated the degree of heavy metal contamination in rice by detecting the contents of lead, cadmium and chromium in 47 samples collected from markets of Zhuhai and Zhongshan cities. She also assessed the health risk from rice consumption by local residents.

Eric Shim from the Computer Science and Technology Programme developed a mobile application with a local medical institution for low-cost ASD (Autism Spectrum Disorders) treatment. His study suggested a mobile puzzle game which incorporated photos of the likes of ASD patients’ caregivers to help accustom the users to eye contact with others.

Environmental Science student Zhong Shiyao compared bird biodiversity in freshwater ponds, Fengshui Woods and Lychee Orchard at Huitong Village, Zhuhai, where UIC’s new campus will be located. This research recommended some ways of protecting the ecosystem at Huitong Village in its future development.
