What is seer2?

As an AI language model, I do not have access to specific information about a subject that has not been mentioned in the prompt. However, SEER2 could refer to SeER 2.0 (Scalable and Efficient Reasoning framework), which is a framework for building scalable probabilistic models for knowledge representation and reasoning. It allows for efficient and flexible reasoning with large knowledge graphs and has been used in applications such as natural language processing, chatbots, and recommendation systems. SeER 2.0 was developed by the USC Information Sciences Institute.
