# Lexilogia Discussions

17,814 public threads — 235,889 posts — from [Lexilogia](https://www.lexilogia.gr),
a Greek forum where translators, editors and language professionals work out hard
questions in the open: what a term should be in Greek, why one rendering beats
another, where a usage came from.

It is published as a research corpus for Greek language technology, which has
very little conversational data of this quality and almost none of it argued
through to a conclusion.

```python
from datasets import load_dataset
ds = load_dataset("Greekpt/lexilogia-discussions", split="train", streaming=True)
```

## What a record contains

One thread per record: its title and URL, the opening post, every reply in order,
and a participant list giving who posted and at which positions. Replies carry
the handle that wrote them and, where the forum recorded it, the post they were
answering. Post bodies are the redacted form produced at collection — signatures
and moderation notes are separated out rather than inlined.

`strip_profiles_and_timestamps.py` in this repository is the exact transform
applied before publication. It removes links to member profile pages, and it
removes when things happened — post times, thread activity times, collection
times. Nothing else was changed.

## Handles are kept

Members are named as they name themselves on a public forum. Removing that was
tried and abandoned: on a forum about words, the handles collide with the
vocabulary under discussion, and replacing them in running text damages the exact
content the corpus exists to preserve. Following who is answering whom is most of
what makes these threads worth reading.

That means this dataset contains personal data: a handle, and what that person
wrote and argued over the years. It is drawn entirely from pages Lexilogia serves
publicly, but "already public" is a description, not a permission.

## Rights and removal

Under Lexilogia's terms, **copyright stays with the individual authors**. This
corpus is published for non-commercial research and is not offered as a licence
to anyone's writing.

If you posted on Lexilogia and want your content out, or you are Lexilogia staff
and want the whole thing down, open a discussion on this repository or write to
`foivos.karounos@eellak.gr`. Removal needs no justification. Records carry a
stable `author_key`, so removing one member's posts is exact rather than
best-effort, and removals carry into anything released from this corpus
afterwards.

## Built from this

[`Greekpt/greek-forum-reasoning-traces`](https://huggingface.co/datasets/Greekpt/greek-forum-reasoning-traces)
— reasoning traces written from these threads, and
[the pipeline](https://github.com/fffoivos/greek-forum-reasoning-traces-pipeline)
that produces them.
