Abstract

Enriched by natural language texts, Stack Overflow code snippets are an invaluable code-centric knowledge base of small units of source code. Besides being useful for software developers, these annotated snippets can potentially serve as the basis for automated tools that provide working code solutions to specific natural language queries. With the goal of developing automated tools with the Stack Overflow snippets and surrounding text, this paper investigates the following questions: (1) How usable are the Stack Overflow code snippets? and (2) When using text search engines for matching on the natural language questions and answers around the snippets, what percentage of the top results contain usable code snippets? A total of 3M code snippets are analyzed across four languages: C\#, Java, JavaScript, and Python. Python and JavaScript proved to be the languages for which the most code snippets are usable. Conversely, Java and C\# proved to be the languages with the lowest usability rate. Further qualitative analysis on usable Python snippets shows the characteristics of the answers that solve the original question. Finally, we use Google search to investigate the alignment of usability and the natural language annotations around code snippets, and explore how to make snippets in Stack Overflow an adequate base for future automatic program generation., Comment: 13th IEEE/ACM International Conference on Mining Software Repositories, 11 pages

Abstract

We have suggested a new modified iterative scheme for approximating a common fixed point of two G-nonexpansive mappings. Our approach was based on an iterative scheme in the context of Banach spaces via directed graphs. First, we proved a weak convergence theorem using the Opial's property of the underlying space. A weak convergence result without the Opial's property was also given. After this, we established several strong convergence theorems using various mild conditions. We also carried out some numerical simulations to examine the main techniques. Eventually, we obtained an application of our result to solve split feasibility problems (SFP) in the context of G-nonexpansive mappings. [ABSTRACT FROM AUTHOR]

Abstract

The present study aimed to investigate the impact of Artificial Intelligence (AI) Chatbots on academic self-efficacy and self-regulation among university students. To test the moderating effect of self-regulation on the association between AI Chatbots and academic self-efficacy. In addition, the research aligns with highlighted social debates surrounding ethical quandaries surrounding AI adoption in education. Using purposive sampling technique data was collected from universities students (N = 350) based in Rawalpindi and Islamabad. Along with demographic information, data was collected on the measures of the Human-Computer Trust Scale, Academic Self-Efficacy Scale, and Short-Form Self-Regulation Questionnaire to assess study variables. Results showed that AI Chatbots and Self-Regulation positively predict academic self-efficacy. AI Chatbots help in growing educational technologies and provide the education sector and policymakers for enhancing the level of education by adding tools for performance. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we introduce the novel concept of generalized distance denoted as J θ and call it an extended b-generalized pseudo-distance. With the help of this generalized distance, we define a generalized point to set distance J θ (u , H ★) , a generalized Hausdorff type distance and a P J θ -property of a pair (H ★ , K ★) of nonempty subsets of extended b-metric space (U ★ , ρ θ). Additionally, we establish several best proximity point theorems for multi-valued contraction mappings of Nadler type defined on b-metric spaces and extended b-metric spaces. Our findings generalize numerous existing results found in the literature. To substantiate the introduced notion and validate our main results, we provide some concrete examples.
