Brief

GEMCo is a human-authored, releasable proxy for privacy-restricted German e-mail counselling data, comprising 86 conversations (728 messages) derived from expert cases and role-play sessions. The authors validate it against 124 held-out real conversations and report a measurable but small difference in counsellor strategies and client emotions, with a generative validation and a generalisable validation method. Summary based on the abstract; full text not reviewed.

Why it matters

GEMCo is a human-written, ethically releasable proxy dataset of German e-mail counselling containing 86 complete conversations (728 messages) produced from expert-authored cases and trained role-player counsellor sessions.

Key details

  • The proxy was validated against a held-out reference of 124 real counselling conversations; evaluations on counsellor strategies and client emotions show a detectable but small gap, supported by a generative validation.

Abstract

This paper presents GEMCo, a releasable, human-written proxy for inaccessible counselling data: 86 complete German e-mail counselling conversations (728 messages), expert-authored cases and counsellor sessions with trained role-players. It is validated against a held-out reference of 124 real counselling conversations. The proxy and the real conversations are measured against each other in counsellor strategies and client emotions. The gap is detectable but small. A generative validation supports the analysis. The validation method itself generalises to any domain where real data cannot be shared but a human-made proxy can. Privacy and ethics keep real counselling data closed. GEMCo carries none by design and can be released -- a first step toward language research in this domain.
