Abstract:
Can structured data management play an important role in accelerating AI? In this talk I focus on two main aspects of structured data management and argue that they are key in powering and accelerating AI application development: (1) automating data quality and cleaning using generative models; and (2) constructing and serving structured knowledge graphs and their role in semantic annotation and grounding unstructured data.
In the first thrust, I will summarize our findings building the HoloClean project. HoloClean builds generative probabilistic models describing how data was intended to look like, and uses them for predicting errors and repairs. On the structured knowledge front, I will describe our work building Saga, an end-to-end platform for incremental and continuous construction of large scale knowledge graphs. Saga demonstrates the complexity of building such platform in industrial settings with strong consistency, latency, and coverage requirements.
I will discuss challenges around building entity linking and fusion pipelines for constructing coherent knowledge graphs; updating the knowledge graphs with real-time streams; and finally, exposing the constructed knowledge via ML-based entity disambiguation and semantic annotation. I will also show how to query such knowledge via vector representation capable of handling hybrid similarity/filtering workloads.
