My research has been published on Zenodo (DOI: 10.5281/zenodo.21641412). My approach combines deep linguistic analysis with a proprietary logical system to reduce model hallucinations and improve reasoning accuracy. **Depth of annotation – your choice:** - Basic – fast, high‑volume labeling (syntax, POS, named entities). - In‑depth – precise semantic analysis, logical relations, modality, and contextual meaning. **Output formats:** JSONL, JSON, CSV, XML, Markdown, TXT, MartML (my custom flexible format), or any other format you need. I can also convert from your existing format. **My tools:** 1. MartML – a custom markup language that allows annotation at any depth, not limited by rigid templates. 2. Gayane Logic – a 4‑valued logical system that helps reduce AI hallucinations by distinguishing necessary truths from contingent ones. **Services:** 1. Dataset annotation and creation. 2. Consultations on annotation strategy – structure, depth, and optimal approach for your specific task. **Send me a sample of your data and a brief description of your task – let's discuss the best solution.** **Consultations on MartML / Gayane Logic architecture are billed separately, as they involve proprietary technology and years of R&D.** #LLM #DatasetAnnotation #DataAnnotation #DataLabeling #FineTuning #LLMTraining #NLP #MachineLearning #AI #TrainingData #JSONL #DatasetCreation #DataForAI less -
