Questions Per Year

-1: 2,694
2015: 99,664
2016: 120,887
2017: 20,791
2018: 20,096
2020: 99,676
2022: 415,121 (Note: 2017/2018 low counts reflect sampling focus; 2022 dominates at 53%)

⚠️ Known Issues & Caveats

YEAR GAPS: Years 2019 and 2021 are absent — this is a sampling artifact, not a gap in SO activity. Do not use for temporal trend analysis without noting this.
2022 DOMINANCE: 415,121 questions (53%) are from 2022. The dataset skews heavily toward recent questions. Stratify by year if balance matters.
RAW HTML: question_body contains raw HTML including <, >, <pre><code> blocks. Use body_text for NLP tasks. Use question_body for HTML-aware or code-extraction tasks.
SCORE SKEW: 59.3% of questions have score=0. Mean (0.69) is misleading. Use score_bucket or is_highly_voted for classification tasks.
VIEW COUNT SKEW: Mean (794) is 12× the median (66) due to viral questions. Use log-transformed view_count for regression tasks.
PIPE-SEPARATED TAGS: The tags column uses | as delimiter e.g. python|pandas|dataframe. Split with str.split("|") before use.
CODE PLACEHOLDER: In body_text, all <pre>...</pre> blocks are replaced with the token [CODE]. The original HTML is preserved in question_body.
DUPLICATE IDs: 2 exact duplicates were found and removed during processing.

🚀 Quick Start

pandas

import pandas as pd

# Full dataset
df = pd.read_csv("data/stackoverflow_778k_full.csv")

# High quality only (score >= 5, answered)
hq = pd.read_csv("data/stackoverflow_high_quality.csv")

# Python questions only
py = pd.read_csv("data/stackoverflow_python.csv")

# Unanswered questions (good for difficulty modeling)
ua = pd.read_csv("data/stackoverflow_unanswered.csv")

# Split tags into list
df["tag_list"] = df["tags"].str.split("|")

# Filter by year
df_2022 = df[df["year"] == 2022]

# Log-transform view count for regression
import numpy as np
df["log_views"] = np.log1p(df["view_count"])

HuggingFace datasets

from datasets import load_dataset

REPO = "Omarrran/StackPulse_778K_QnA_Code_dataset"

# Full 778K
ds = load_dataset(REPO, "full")

# High quality only
hq = load_dataset(REPO, "high_quality")

# Python questions
py = load_dataset(REPO, "python")

# Unanswered questions
ua = load_dataset(REPO, "unanswered")

# Convert to pandas
df = ds["train"].to_pandas()

🔬 Suggested Research Tasks

Task	Config	Key Columns
Answer prediction (binary)	full	title, body_text, tags → is_unanswered
Score regression	full	title, body_text, tags → score
