1. Developing conversational virtual assistants (e.g., Amelia, Haptik, and Lex) for different clients, including creating user stories, crafting and annotating semantic and syntactic components (e.g., intents, entities, and conversation data), training the machine learning models for AI systems, maintaining both linguistic and functional QA testing and bug fixing in the life cycle of products. 2. Developing NLP models. Researching and developing neural natural language models, such as sequence-to-sequence architectures (e.g., text summarization), as embedded applications in the conversational robots; prototyping LLM-related apps. 3. Running text mining projects for business intelligence, including tabular stats, semantic similarity/clustering (e.g., topic model), semantic search, key term extraction, sentiment analysis, and time analysis. 4. Supporting the team with QA and annotations and evaluation for ASR 5. Performing automation development and management 6. Conducting business interviews to extract use cases, reporting ML/analytics results, and showing product demos to stakeholders and clients. Show less
