情感检测是多种信息检索任务的重要组成部分,例如产品推荐,网络欺凌,假新闻和错误信息检测。毫不奇怪,现在有多种商业API,每种API都具有不同的准确性和公平性,可用于情感检测。用户可以轻松地将这些API集成到他们的应用程序中。虽然在多媒体计算文献中通常研究了将来自多个模态或黑盒模型的输入相结合以提高准确性,但是在将不同的模态相结合以提高所产生的决策的公平性方面的工作很少。在这项工作中,我们审计了多个商业情感检测API,用于两个演员新闻标题设置中的性别偏见,并报告了观察到的偏见水平。接下来,我们提出了一种“灵活的公平回归”方法,该方法通过从多个黑盒模型中联合学习来确保令人满意的准确性和公平性。这些结果为多个应用程序的公平而准确的情感检测器铺平了道路。
Sentiment detection is an important building block for multiple information retrieval tasks such as product recommendation, cyberbullying, fake news and misinformation detection. Unsurprisingly, multiple commercial APIs, each with different levels of accuracy and fairness, are now publicly available for sentiment detection. Users can easily incorporate these APIs in their applications. While combining inputs from multiple modalities or black-box models for increasing accuracy is commonly studied in multimedia computing literature, there has been little work on combining different modalities for increasingfairness of the resulting decision. In this work, we audit multiple commercial sentiment detection APIs for the gender bias in two-actor news headlines settings and report on the level of bias observed. Next, we propose a "Flexible Fair Regression" approach, which ensures satisfactory accuracy and fairness by jointly learning from multiple black-box models. The results pave way for fair yet accurate sentiment detectors for multiple applications.
