Explaining automatic answers generated from knowledge base embedding models
[thesis]
While many chatbot systems rely on templates and shallow semantic analysis, advanced question-answering devices are typically produced with the help of largescale knowledge bases such as DBpedia or Freebase. Information extraction is often based on embedding models that map semantically rich information into low-dimensional vectors, allowing computationally efficient calculations. When producing new facts about the world, embeddings often provide correct answers that are very hard to explain
