  • Consumer Evaluations of Organic Agricultural Products on an E-Commerce Mall

    SHIBUYA Hitoshi, KATO Kosuke, YAMAMOTO Junko

    Journal of Food System Research ( The Food System Research Association of Japan )  30 ( 4 ) 255 - 260   2024

    Type of publication: Research paper (other science council materials etc.)

    　View Summary

    This paper aims to characterize post-purchase evaluations of organic compared to non-organic agricultural products by applying text mining to consumer reviews on an e-commerce mall. We employ coding analysis to identify perspective differences and document scaling analysis to extract elements demonstrating divergent evaluation tendencies. The analysis revealed that health and safety expectations and interest in farmers were associated with positive evaluations of organic products, while environmental protection was a minor consideration. The evaluation criteria for attributes such as appearance and smell differed from those for non-organic agricultural products.

  • Understanding Research Trends and Topics on Organic Agriculture based on Scientific Literature in Social Science: A Scientometric Analysis using Citespace

    KATO Kosuke, YAMAMOTO Junko, KOBAYASHI Hiroaki

    Journal of Food System Research ( The Food System Research Association of Japan )  29 ( 4 ) 237 - 242   2023

    Type of publication: Research paper (other science council materials etc.)

    　View Summary

    This study focuses on detecting trends and topics in social science research on organic agriculture. We applied scientometric methods, such as keyword co-occurrence analysis and burst detection to keywords assigned to scientific literature related to the social sciences from 2002 to 2021. As a result, various research topics on organic agriculture from production to consumption aspects were detected. Furthermore, recent trends in social science research were detected quantitatively. These trends included meta-analysis through case study accumulation and research topics related to organic agriculture and sustainability.

  • Feature Extraction of Consumers' Evaluation about Beef Including By-products Based on Online Reviews in E-Commerce

    Hattori Akihiko, Kato Kosuke, Yamamoto Junko

    Journal of Rural Problems ( The Association for Regional Agricultural and Forestry Economics )  58 ( 3 ) 141 - 148   2022.09 [ Peer Review Accepted ]

    Type of publication: Research paper (other science council materials etc.)

    　View Summary

    This study aimed to explore consumer evaluations of beef by part, including its by-products. To achieve this, we analyzed online product reviews on Rakuten Ichiba (a major e-commerce site) from 2016 to 2019. We applied text mining analyses to these data in three stages: extraction of frequent words in the whole beef review to capture the overall characteristics; grouping of parts by correspondence analysis; and extraction of words that characterize each part to consider similarities and differences among parts or groups of parts. We found that for post-purchase evaluation criteria and consumption practices, several parts had some similarities, but there were also differences among several other parts and groups. Therefore, to further understand the needs of the consumer and promote the sales of beef, it would be advisable to consider the characteristics of each group of parts and each part individually.

  • Change in Consumer Behavior and Eating Habits during the Spread of COVID-19: An Analysis of Consumer Data Collected Through Depth Interview

    YAMAMOTO Junko, UENISHI Yoshihiro

    Journal of Food System Research ( The Food System Research Association of Japan )  28 ( 3 ) n/a   2021

    Type of publication: Research paper (other science council materials etc.)

    　View Summary

    Using a depth interview, this study analyzed the change in consumer behavior and eating habits during the spread of the COVID-19 pandemic. The results showed that during April to May 2020, most respondents had reduced the frequency of shopping. Some of them cooked new dishes and increased the number of meals as they stayed at home for longer hours and had enough time in hand for cooking. We also noted that during March to May 2021, when the work schedule returned to pre-COVID-19 times, the frequency of shopping and meal menus returned as well.
