Benchmarking Machine Learning Models for Need Identification  \nSven Stahlmann University of Cologne stahlmann@wim.uni[koeln.de](koeln.de)  \nOliver Ettrich Kühne Logistics University oliver.ettrich@the[klu.org](klu.org)  \nMarco Kurka University of Cologne kurka@wim.uni[koeln.de](koeln.de)  \nDetlef Schoder University of Cologne schoder@wim.uni[koeln.de](koeln.de)  \nAbstract  \nNeedmining is the process of extracting customer needs from user-generated content by classifying it as either informative or uninformative regarding need content. Contemporary studies achieve this by utilizing machine learning. However, models found in the literature cannot be compared to each other because they use private data for training and testing. This study benchmarks all previously suggested needmining models including CNN, SVM, RNN, and RoBERTa. To ensure an unbiased comparison, this study samples and annotates a dataset of customer reviews for products from 4 different categories from amazon. Henceforth, the dataset is publicly available and serves as a gold-set for future needmining benchmarks. RoBERTa outperformed other classifiers and seems to be best suited for needmining. The relevance of this study is reinforced by the fact that this benchmark creates a different hierarchy between models than otherwise suggested by comparing the results of previous studies.  \nKeywords: machine learning, natural language processing, customer needs, product innovation  \n1. Introduction  \nKnowing and understanding customer needs is an important tool to increase customer satisfaction and the quality of products and services (Matzler & Hinterhuber, 1998) . For marketing departments, this can help to segment the market, identify strategic decisions (Park et al., 1986), and lead to better channel management decisions (Timoshenko & Hauser, 2019) . For research and development departments, customer needs help to identify new product opportunities (Eppinger & Ulrich, 2015; Herrmann et al., 2000) or improve existing ones (Matzler & Hinterhuber, 1998) . Therefore, knowing and understanding these needs is of great economic value.  \nTo exploit this economic value, methods such as observations, surveys, and interviews are traditionally  \nused to identify such needs (Edvardsson et al., 2012; Griffin & Hauser, 1993) . However, these methods do not scale for large amounts of data, since a major part of the work is manual labor (Kühl et al., 2020) . Additionally, these methods are cost-intensive (Fisher et al., 2014), time-consuming (Griffin & Hauser, 1993) and can result in a delay of time to market.  \nUser-generated content (UGC) such as Amazon reviews and Twitter microblogs can be a low-cost source of customer needs (Kuehl et al., 2016) and are readily available in large quantities. Using traditional methods to identify needs in UGC is not feasible since the bulk of the content is either uninformative (i.e. it does not contain any needs) or repetitive. This results in high labor costs when analyzing UGC manually (Timoshenko & Hauser, 2019) because a lot of time is wasted on reading content that adds no value to market researchers. Consequently, a new, efficient approach to extract customer needs from UGC is needed. Machine learning looks to be a promising method to filter this vast amount of available UGC for need-containing content.  \nStudies tackling this problem already exist (e.g. Christensen et al., 2017; Kuehl et al., 2016; Stahlmannet al., 2022; Timoshenko & Hauser, 2019; Zhang et al., 2021) . These studies apply various supervised machine learning classifiers to separate UGC into informative (defined as containing customer needs) and uninformative content. This is referred to as‘needmining’ (Kuehl et al., 2016) . Experts process the informative content further to extract insights for purposes such as innovation and product development.
