Therefore, detecting toxic comment becomes an active research area, and it is often handled as a text classification task. As recent popular methods for text classification tasks, pre-trained language model-based methods are at the forefront of natural language processing, achieving state-of-the-art performance on various NLP tasks. However, there is a paucity in studies using such methods on toxic comment classification. In this work, we study how to best make use of pre-trained language model-based methods for toxic comment classification and the performances of different pre-trained language models on these tasks. Our results show that, Out of the three most popular language models, i.e. BERT, RoBERTa, and XLM, BERT and RoBERTa generally outperform XLM on toxic comment classification. We also prove that using a basic linear downstream structure outperforms complex ones such as CNN and BiLSTM. What is more, we find that further fine-tuning a pre-trained language model with light hyper-parameter settings brings improvements to the downstream toxic comment classification task, especially when the task has a relatively small dataset.","PeriodicalId":129420,"journal":{"name":"Companion Proceedings of the Web Conference 2021","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124565826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Power is one of the most constrained and difficult to manage resources in datacenters. Accurate accounting of power usage across clients of multi-tenant web services can improve budgeting, planning and provisioning of compute resources. In this work, we propose a queuing theory based transitive power modeling framework that estimates the total power cost of a client request across the stack of shared services running in Facebook datacenters. By capturing the non-linearity of power vs load relation, our model is able to estimate marginal change in power consumption of a system upon serving a request with a mean error of less than 4% when applied on production services. In view of the fact that datacenter capacity is planned for peak demand, we test this model at peak load to report up to 2x improvement in accuracy compared to a mathematical model. We further leverage this framework along with a distributed tracing system to estimate power demand shift for serving particular product features within fraction of a percentage and guide the decision to shift their computation at off-peak time.","PeriodicalId":129420,"journal":{"name":"Companion Proceedings of the Web Conference 2021","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115841130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of the Fourth Industrial Revolution, that need is even more urgent since technological sectors are men-dominated. Despite the significant progress made towards gender inequality in the last decades, we are far from the ideal scenario. Changes towards equality are too slow and uneven across different world regions. Monitoring gender parity is essential to understand priorities and specificities in each world region. However, it is challenging because of the scarcity and the cost to obtain data, especially in less developed countries. In this paper we study how the Facebook Advertising Platform (Facebook Ads) can be used to assess gender imbalance in education, focusing on STEM (Science, Technology, Engineering, and Mathematics) areas, which are the main focus of the Fourth Revolution. As a case study, we apply our methodology to characterize Brazil in terms of gender balance in STEM as well as to correlate the results using Facebook Ads data with official Brazilian government numbers. Our results suggest that even considering a biased population where the majority is female, the proportion of men interested in some majors is higher than the proportion of women. Within STEM areas, we can identify two different patterns. Life Science and Math/Physical Sciences have female dominance, Environmental Science, Technology, and Engineering majors are still concentrated towards men. We also assess the impact of educational level and age on the interest in majors. The gender gap in STEM increases with the women’s educational level and age, as confirmed by official data in Brazil.","PeriodicalId":129420,"journal":{"name":"Companion Proceedings of the Web Conference 2021","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124409255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

City's DT is another challenging and complex process, which demands both the leading and dedicated role of the local government, and the engagement and commitment of the local stakeholders on a commonly agreed vision and plan. European Commission launched its Digital (DCC) and Intelligent Cities Challenge (ICC) initiatives to provide cities with guidance and support to design and implement corresponding digital transformation strategies. Shaping this strategy became hard during the ICC due to the Covid-19 pandemic, which changed all the local priorities and affected the initial city planning. The aim of this work-in-progress paper is to present the strategic planning process for city's digital transformation that was followed by the municipality of Trikala in Greece, which regardless is a famous smart city it had to join the DCC and ICC initiatives in order to methodologically perform it. Useful evidence are depicted with regard to the different stakeholders’ perspectives and priorities within the city's digital transformation and especially whether and how the COVID-19 outbreak re-arranged or re-shaped them.","PeriodicalId":129420,"journal":{"name":"Companion Proceedings of the Web Conference 2021","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133209249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
