Besides writing fundamentals such as syntax and grammar, learners must select and arrange argument components meaningfully to create high-quality essays. To support argumentative writing computationally, one step is to mine the argumentative structure. When combined with automatic essay scoring, interactions of the argumentative structure and quality scores can be exploited for comprehensive writing support. Although studies have shown the usefulness of using information about the argumentative structure for essay scoring, no argument mining corpus with ground-truth essay quality annotations has been published yet. Moreover, none of the existing corpora contain essays written by school students specifically. To fill this research gap, we present a German corpus of 1,320 essays from school students of two age groups. Each essay has been manually annotated for argumentative structure and quality on multiple levels of granularity. We propose baseline approaches to argument mining and essay scoring, and we analyze interactions between both tasks, thereby laying the ground for quality-oriented argumentative writing support.","lang":"eng"}],"user_id":"47857","_id":"54513","language":[{"iso":"eng"}],"keyword":["Annotation","Corpus","Argumentative Structure"]},{"author":[{"last_name":"Shivarpatna Venkatesh","full_name":"Shivarpatna Venkatesh, Ashwin Prasad","id":"66637","first_name":"Ashwin Prasad"},{"first_name":"Jiawei","last_name":"Wang","full_name":"Wang, Jiawei"},{"full_name":"Li, Li","last_name":"Li","first_name":"Li"},{"first_name":"Eric","id":"59256","full_name":"Bodden, Eric","orcid":"0000-0003-3470-3647","last_name":"Bodden"}],"date_created":"2023-01-13T08:03:26Z","publisher":"IEEE SANER 2023 (International Conference on Software Analysis, Evolution and Reengineering)","oa":"1","date_updated":"2025-04-07T10:18:03Z","conference":{"name":"IEEE SANER 2023 (International Conference on Software Analysis, Evolution and Reengineering)"},"doi":"10.48550/ARXIV.2301.04419","title":"Enhancing Comprehension and Navigation in Jupyter Notebooks with Static Analysis","has_accepted_license":"1","citation":{"apa":"Shivarpatna Venkatesh, A.

Data scientists use Jupyter notebook as the de-facto standard for creating and sharing machine-learning based solutions, primarily written in Python. Recent studies have demonstrated, however, that a large portion of Jupyter notebooks available on public platforms are undocumented and lacks a narrative structure. This reduces the readability of these notebooks. To address this shortcoming, this paper presents HeaderGen, a novel tool-based approach that automatically annotates code cells with categorical markdown headers based on a taxonomy of machine-learning operations, and classifies and displays function calls according to this taxonomy. For this functionality to be realized, HeaderGen enhances an existing call graph analysis in PyCG. To improve precision, HeaderGen extends PyCG's analysis with support for handling external library code and flow-sensitivity. The former is realized by facilitating the resolution of function return-types. Furthermore, HeaderGen uses type information to perform pattern matching on code syntax to annotate code cells.\r\nThe evaluation on 15 real-world Jupyter notebooks from Kaggle shows that HeaderGen's underlying call graph analysis yields high accuracy (96.4% precision and 95.9% recall). This is because HeaderGen can resolve return-types of external libraries where existing type inference tools such as pytype (by Google), pyright (by Microsoft), and Jedi fall short. The header generation has a precision of 82.2% and a recall rate of 96.8% with regard to headers created manually by experts. In a user study, HeaderGen helps participants finish comprehension and navigation tasks faster. All participants clearly perceive HeaderGen as useful to their task."}]},{"citation":{"apa":"Kim, Y., Lee, S., Dollmann, M., &#38; Geierhos, M. (2018).
