+# Overview
+This dataset is of conversations extracted from [Aozora Bunko (青空文庫)](https://www.aozora.gr.jp/), which collects public-domain books in Japan, using a simple heuristic approach.
+
+# Method
+First, lines with only quotation marks (`「」`) are extracted as utterances from the `text` field of [globis-university/aozorabunko-clean](https://huggingface.co/datasets/globis-university/aozorabunko-clean).
+Then, consecutive utterances are collected and grouped together.
+
+# Notice
+As the conversations are extracted using a simple heuristic, a certain amount of the data may actually be monologues. 
+
+# Tips
+If you prefer to employ only modern Japanese, you can filter entries with: `row["meta"]["文字遣い種別"] == "新字新仮名"`.
