RefineID-format C++ identifier recovery from The Stack v3
This public benchmark contains 1,000 examples from 1,000 source repositories and 3,961 masked identifier positions. Each example is a full source file with one chosen identifier name masked at every eligible identifier token position. The target is the original name.
Format and use
test.csv has no header and exactly three columns in the same order as the
original RefineID benchmark: id, code_masked, target. IDs are 0 through
999. Each target position is the literal, whitespace-delimited
[MASK]. test.parquet holds the identical rows with named string columns and
is the default Hugging Face test split:
from datasets import load_dataset
ds = load_dataset("D4vidHuang/refineid-stack-v3-cpp", split="test")
assert len(ds) == 1000
provenance.jsonl is aligned by ID and records the upstream repository, commit,
file path, content ID, detected SPDX licenses, source revision, source text hash,
and the half-open Unicode character spans used for masking. manifest.json
records checksums, parameters and corpus-level counts.
Construction and interpretation
Source: HuggingFaceCode/stack-v3-train
at commit 8f3f25d86e44fd691428131efd17af75d4716499. We use the upstream PII-redacted,
quality-filtered train corpus and accept only files marked permissive with
detected licenses. Vendored files, short/oversized files, parse failures,
ambiguous identifier uses, and files with a few obvious remaining sensitive
patterns are excluded. Candidates whose target spelling remains visible in
comments, strings, or other code are also excluded. A seeded Parquet traversal selects at most one
example per repository for this language. This is a deterministic convenience
sample, not a uniform random sample of all Stack v3 files. See the manifest
for the exact seed and scan boundary.
The source is a single code snapshot. These examples evaluate identifier name recovery; they are not observed before/after rename commits. Syntax-tree filters reduce false targets, but they do not prove compiler-resolved binding, compilation, or behavior. Original RefineID has a different source and length/ site distribution, so scores across the two datasets require separate reporting.
License and removal
The Stack v3 collection is ODC-By. Each source file retains its original license;
this dataset does not assign one blanket license to the underlying code. Check the per-row
detected_licenses and upstream repository before reuse. License detection
and PII redaction are imperfect. The Stack v3 card documents its
opt-out process. We pin an
upstream release and will review new opt-outs before future republishes.
