Computationally Assisted Quality Control for Public Health Data Streams

2 code implementations29 Jun 2023 Ananya Joshi, Kathryn Mazaitis, Roni Rosenfeld, Bryan Wilder

However, existing outlier detection frameworks perform poorly on this task because they do not account for the data volume or for the statistical properties of public health streams.

Conversational Neuro-Symbolic Commonsense Reasoning

1 code implementation17 Jun 2020 Forough Arabshahi, Jennifer Lee, Mikayla Gawarecki, Kathryn Mazaitis, Amos Azaria, Tom Mitchell

More precisely, we consider the problem of identifying the unstated presumptions of the speaker that allow the requested action to achieve the desired goal from the given state (perhaps elaborated by making the implicit presumptions explicit).

Open Domain Question Answering Using Early Fusion of Knowledge Bases and Text

2 code implementations EMNLP 2018 Haitian Sun, Bhuwan Dhingra, Manzil Zaheer, Kathryn Mazaitis, Ruslan Salakhutdinov, William W. Cohen

In this paper we look at a more practical setting, namely QA over the combination of a KB and entity-linked text, which is appropriate when an incomplete KB is available with a large text corpus.

Bootstrapping Distantly Supervised IE using Joint Learning and Small Well-structured Corpora

no code implementations10 Jun 2016 Lidong Bing, Bhuwan Dhingra, Kathryn Mazaitis, Jong Hyuk Park, William W. Cohen

We propose a framework to improve performance of distantly-supervised relation extraction, by jointly learning to solve two related tasks: concept-instance extraction and relation extraction.

Efficient Inference and Learning in a Large Knowledge Base: Reasoning with Extracted Information using a Locally Groundable First-Order Probabilistic Logic

no code implementations12 Apr 2014 William Yang Wang, Kathryn Mazaitis, Ni Lao, Tom Mitchell, William W. Cohen

We show that the problem of constructing proofs for this logic is related to computation of personalized PageRank (PPR) on a linearized version of the proof space, and using on this connection, we develop a proveably-correct approximate grounding scheme, based on the PageRank-Nibble algorithm.

Programming with Personalized PageRank: A Locally Groundable First-Order Probabilistic Logic

no code implementations10 May 2013 William Yang Wang, Kathryn Mazaitis, William W. Cohen

In many probabilistic first-order representation systems, inference is performed by "grounding"---i. e., mapping it to a propositional representation, and then performing propositional inference.
