Anonymized usage logs from CIRED.digital, a conversational assistant for exploring CIRED scientific publications stored in the HAL open archive. The dataset covers 1,845 interaction events across 259 user sessions from July to October 2025, including queries, responses, session metadata, and navigation events. Personal identifiers (IP addresses, session IDs, user agents) have been replaced with anonymized derived fields (geographic origin classification, anonymous session IDs, device class labels) to preserve analytical value while protecting user privacy. The analysis pipeline in the companion GitHub repository can reproduce all figures and tables from this archive: git clone https://github.com/CIRED/cired.digital unzip monitor-logs-anon_20260210.zip -d cired.digital/reports/monitor-logs-anon cd cired.digital make LOGS_ROOT=reports/monitor-logs-anon analysis Event types Event typeDescriptionsessionStartNew visitor sessionrequestUser query submittedresponseAI-generated answerarticleGenerated article from queryfeedbackUser rating (thumbs up/down)btnClickUI button interactionvisibilityChangeBrowser tab shown/hidden
