NLP solutions in production can be not so easy. We are presenting our NLP-application for BI — virtual analyst ViTalk and our path of development of this solution. ViTalk can deal with natural language request to the KPI of your business (“what is our income”, “show me only last year”, “compare with current”, etc.) While the NLP parts inside are pretty usual, the real-life implementation has faced its own obstacles. We want to share our experience and show that even low-resource unusual data can lead to successful product.
