Thought Vectors, Knowledge Graphs, and Curious Death(?) of Keyword Search

The world of information retrieval is changing. BERT, Elmo, and the Sesame Street gang are moving in, shouting the gospel of “thought vectors“ as a replacement for traditional keyword search. Meanwhile many search teams are now automatically extracting graph representations of the world, trying their best to also provide more structured answers in the search experience. Poor old keyword search seems so outdated by comparison - is it dead, dying, or simply misunderstood? Contrary to popular belief, embeddings and thought vectors only solve a small subset of search problems, and each of these three tools (keyword search, thought vectors, and knowledge graphs) actually serves a critical role in building the next generation of search experiences. In this talk, we’ll define and highlight the strengths and weaknesses of each of these search methodologies, discuss the role each should play in a modern search solution, and demonstrate where each fails to get the job done and also how they can best compl
