It is important to understand how users’ trust is affected by ML models’ suggestions, even when those models are wrong. Many research efforts have focused on the user’s ability to interpret what a model has learned. In this paper, we seek to understand another aspect of ML interpretability: whether and how the presence of classification probabilities and their different distributions are related to users’ trust in model outcomes, especially in ambiguous instances. To this end, we conducted two online surveys in which we asked participants to evaluate their agreement with image classifications of pictures of animals made by an ML model. In the first, we analyze their trust before and after presenting them the model classification probabilities. In the second, we investigate the relationships between class probability distributions and users’ trust in the model. We found that, in some cases, the additional information is correlated with undue trust in the model’s classifications. However, in others, they are associated with inappropriate skepticism.</div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"72 ","pages":"Article 101149"},"PeriodicalIF":2.2,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72242277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Access policies are a core notion in multiuser environments, such as operating systems and distributed databases. Currently, most of these systems use general data specification languages, such as JSON, XML and YAML to describe access policies. Yet, domain-specific languages are also available for this task. One of such languages is Legalease, from Microsoft. This paper presents a new version of Legalease, called Hapi. Hapi replaces Legalease’s notion of a lattice with a partially ordered set (poset). Posets improve the expressivity of Legalease, at the expenses of a more expensive verification algorithm. This poset-based representation generalizes the notion of actors, actions and resources to user-defined entities. Hapi is publicly available. Its distribution includes a policy visualizer and a code-compression tool to efficiently store specifications.</div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"72 ","pages":"Article 101153"},"PeriodicalIF":2.2,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72242275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, building said abstractions still requires the original author to know where the pitfalls lie and how to avoid them, an implicit contract that does not constitute a guarantee that they will not shoot themselves and their users in the feet.Rust aims to minimize the amount of handguns users have at their disposal, locking them behind special unsafe blocks and restricting the set of possible programs through static analysis; this analysis is performed by the compiler which ensures that the program does not contain memory related errors such as use-after-free bugs.While Rust is able to succeed in the previous domain, other error classes persist, such as errors related to API misusage. Our work aims to tackle that domain, providing a tool which enables developers to write safer APIs using typestates.We propose a macro which embeds a typestate description DSL in Rust which allows developers to specify typestates for their APIs; the typestate is checked at compile-time for common mistakes and to ensure the correct usage of the typestate, we leverage Rust’s type system.Our work only requires a Rust compiler, avoiding workflow bloat and keeping the development experience simple; it is open-source and available at https://github.com/rustype/typestate-rs<svg><path></path></svg>.</div>","PeriodicalId":48552,"journal":{"name":"Journal of Computer Languages","volume":"72 ","pages":"Article 101154"},"PeriodicalIF":2.2,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S259011842200051X/pdfft?md5=2622a5c710cc35277031a7c6298fd301&pid=1-s2.0-S259011842200051X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72242278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
