In the past decade, several key class prediction (KCP) approaches have been proposed. They used design metrics extracted from source code and unweighted network metrics computed on class coupling networks as features and built machine-learning models to predict whether a class is a key class or not. However, previous studies mainly focused on improving the performance of KCP models in the within-project (i.e., KCP in the same project) context, and the network metrics they used are unweighted and inaccurate, as they are computed on unweighted and incomplete class coupling networks. These limitations lead to a lack of thorough evaluation of the effectiveness of network metrics for KCP, especially in the cross-project (KCP across diverse projects) context, which in turn results in uncertainty about how to choose suitable metrics as features when building KCP models. To fill this gap, in this paper, we thoroughly evaluate the effectiveness of network metrics for KCP. Specifically, we build weighted and more complete class coupling networks for software, and introduce a set of weighted network metrics to characterize class complexity. Then, we build different KCP models using the Random Forest learner and the Naive Bayes model for two KCP contexts (i.e., within-project and cross-project), respectively, with design metrics, unweighted/weighted network metrics, and their combinations being features. Finally, through an empirical study on 18 open-source Java projects, we thoroughly investigate the relative effectiveness of network metrics over design metrics across the two KCP contexts. Our results suggest that when building KCP models, to achieve better performance, researchers and practitioners should consider using unweighted (or weighted) network metrics alone or along with design metrics in the within-project KCP context, using design metrics alone or along with unweighted (or weighted) network metrics in the cross-project KCP context, and using unweighted (or weighted) network metrics along with design metrics across the two KCP contexts.</p>","PeriodicalId":20189,"journal":{"name":"PLoS ONE","volume":"20 10","pages":"e0334408"},"PeriodicalIF":2.6,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12513632/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145275508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this pilot study, we use a novel application of paleolimnological proxies to track environmental change using bird nests. Specifically, we examine long-term population dynamics of the Northern Common Eider (Somateria mollissima borealis), a philopatric sea duck. Eider nests from the Canadian sub-Arctic were sampled and radioisotopically dated, indicating that eiders have been nesting here since the 1800s. To assess the applicability of paleoecological proxies in nests to monitor environmental changes and long-term eider population dynamics, we examined changes in diatom species composition, shifts in the abundance of siliceous proxies (i.e., diatoms, chrysophyte cysts, phytoliths, protozoan plates), visible reflectance spectroscopy-inferred chlorophyll a (VRS-chla), stable nitrogen isotopes, and a selection of metal(loid)s. Warmer post-Little Ice Age conditions after the mid-19th century, together with higher eider occupation rates, promoted the proliferation of diatoms and other siliceous indicators. Declining eider populations during the industrial era, likely due to increased hunting pressures, was indicated by declines in δ15N values and relative abundances of diatom taxa typically associated with higher nutrients and/or moisture. Increasing concentrations of metals (i.e., Zn and Cd), δ15N values, and VRS-chla, which are positively associated with eider nesting activity, provided further support that eider numbers increased during the latter part of the 20th century. Our study shows that the accumulated vegetative and peat material from eider nests can provide a powerful tool to track historical bird population dynamics in ways that traditional, more recent, population monitoring methods cannot.
