ParlAI: A new software platform for dialog research

Introduced ParlAI, an open-source platform for dialog research, unifying tasks and training algorithms in a single repository. Integrated Mechanical Turk for data collection, training, and evaluation. Categorized dialog tasks into question answering, sentence completion, goal-oriented dialog, chit-chat dialog, and visual dialog. Defined core concepts: worlds, agents, and teachers, using a unified observation/action object format. Included initial agents like IR baselines, an end-to-end memory network (Lua Torch), and an attentive LSTM model DrQA (PyTorch).
