TagTog
Biomedical text annotation tool; its domains have lapsed (retired).
Retired
TagTog appears to be discontinued or shut down — tagtog.com now serves a domain-parking page and tagtog.net is unreachable; the company appears defunct. Historical feature set documented via third-party vendor listings. This page is kept as an archive record and is excluded from search engines.
About
TagTog was a web-based annotation framework built for biomedical NLP: gene mentions, ontology concepts, and relations in full-text articles. It grew out of a BioCreative collaboration with FlyBase (Cejuela et al., 2014), where assisted curation was shown to beat manual annotation on speed. Its feature set included overlapping and nested spans, entity normalization against reference dictionaries, active learning, PubMed import, OCR pipeline integration, and export to JSON, CoNLL, and Brat formats, with cloud SaaS and on-prem Docker deployment. The product's web presence has lapsed: tagtog.com now serves a domain-parking page and tagtog.net is unreachable (both verified), leaving third-party vendor listings as the only remaining product descriptions. With no live official site verifiable, the honest classification is retired.
What it can do
- Overlapping spans, nested entities, and typed relations
- Entity normalization to reference dictionaries
- Active learning with user feedback loops
- Native PubMed import and OCR integrations
- Export to JSON, CoNLL, and Brat formats
- Cloud SaaS or on-prem Docker deployment
Setup
No longer available; the official domains have lapsed.

Trust score — 3/10
Scored 3/10 (verified tier, metrics-v1). Evidence: tagtog.com serves a domain-parking page and tagtog.net is unreachable (both verified via curl); peer-reviewed BioCreative/FlyBase pedigree (2014); third-party vendor listing describes the historical feature set. Strengths: real academic pedigree, well-documented feature set. Docked for: (1) no live official site or product verifiable; (2) appears defunct with no announcement found. License: defunct commercial product.
