Dataset Structure
The dataset comprises 11 columns, detailed as follows:
task_type: Identifies the task category, with options includinginfilling_java,completion_java,infilling_python, andcompletion_python.code_task: Describes the nature of the coding tasks. For Java, the tasks involve advanced academic projects focusing on text processing, data structures (such as AVL, B-tree, M-Tree), and statistical algorithms. Python tasks span from notebook scripts to object-oriented programming, covering areas like linear programming, computer vision, and reinforcement learning.start_lineandend_line: Specify the beginning and ending line numbers of the code segment targeted for completion.before,between, andafter: Capture the code preceding the target code block, the ground truth of the target code block, and the code following the target block, respectively.reason_categories_output: A collection of dictionaries detailing theusage_linefor logical components within the target code block, including elements likeIf Body,If Condition,Loop Body, etc.horizon_categories_output: Documents the programming constructs such asGlobal_Variable,Function,Class, along with theirdefine_lineandusage_line.reason_freq_analysisandhorizon_freq_analysis: These dictionaries tally the occurrences withinreason_categories_outputandhorizon_categories_output, respectively.
Dataset Creation
Curation Rationale
Currently, the most widely-used benchmarks for checking the ability of AI models to perform program synthesis (``AI-for-code'') consist of a detailed English description of a concise, self-contained code to synthesize, as well as a few test cases to test the correctness of the synthesized code. While such benchmarks are useful, they match one particularly narrow use case, where the goal is to synthesize a relatively short, complete, standalone program.
We introduce SimCoPilot, a novel benchmark crafted to simulate the ability of an AI such as a large language model (LLM) to perform as a ``copilot''-style, interactive coding assistant.
Source Data
Source Code
Data Collection and Processing
Emails were sent to faculty and students within the Rice University Computer Science, Electrical Engineering, and Statistics departments, inviting them to contribute Java and Python code private repositories for AI-for-code research. Upon receipt, 1,163 code generation tasks were curated to ensure a diverse and representative sample of real-world code, gathering approximately 11,000 lines of code.
Who are the source data producers?
The dataset includes Java and Python code contributions primarily from students and faculty at Rice University's Computer Science department, Electrical Engineering, and Statistics departments, representing a community of academic programmers and developers.
Annotations [optional]
Annotation process
Each of the 1,163 programming tasks was created from eight Java repositories and seven Python repositories, totaling nearly 11,000 lines of code.
Our team went through these codes, generating both infill and completion tasks.
To create an infill task, the annotator picks a meaningful starting point for the AI-for-code model to begin writing code (at the beginning of the boolean if condition, or at the beginning of the body of a for loop, for example)
and then marks the rest of that particular code block for deletion, to be re-created by the AI-for-code model.
In the case of an if condition, the entire boolean predicate would be marked for deletion.
In the case of a for-loop body, the entire body would be marked.
A completion task is created in much the same way, but the code for the remainder of the method or function is marked for deletion.
Who are the annotators?
A team of graduate students from Rice Univerity with medium to advanced programming skill level with 5-10 years experience each.
Personal and Sensitive Information
N/A
Bias, Risks, and Limitations
Sample Bias: Contributions mainly from students and faculty at a single institution (Rice University) could reflect a biased sample of coding styles, proficiency levels, and problem-solving approaches. Overfitting Risks: Models trained on this dataset might perform well on similar academic or controlled environments but may not generalize well to diverse coding tasks outside of these parameters.
Recommendations
Diversifying the Data Sources: Expand the dataset to include code from a broader range of contributors beyond the academic circle of Rice University. This could involve soliciting code from developers in different industries, countries, and cultural backgrounds to enhance the dataset's diversity and representativeness. Cross-Validation with External Datasets: Use external datasets for cross-validation of the AI models trained with this dataset. This helps in assessing the model’s performance and generalizability to other coding environments and tasks.
