Query: Logician: A Unified End-to-End Neural Approach for Open-Domain
  Information Extraction   In this paper, we consider the problem of open information extraction (OIE)
for extracting entity and relation level intermediate structures from sentences
in open-domain. We focus on four types of valuable intermediate structures
(Relation, Attribute, Description, and Concept), and propose a unified
knowledge expression form, SAOKE, to express them. We publicly release a data
set which contains more than forty thousand sentences and the corresponding
facts in the SAOKE format labeled by crowd-sourcing. To our knowledge, this is
the largest publicly available human labeled data set for open information
extraction tasks. Using this labeled SAOKE data set, we train an end-to-end
neural model using the sequenceto-sequence paradigm, called Logician, to
transform sentences into facts. For each sentence, different to existing
algorithms which generally focus on extracting each single fact without
concerning other possible facts, Logician performs a global optimization over
all possible involved facts, in which facts not only compete with each other to
attract the attention of words, but also cooperate to share words. An
experimental study on various types of open domain relation extraction tasks
reveals the consistent superiority of Logician to other states-of-the-art
algorithms. The experiments verify the reasonableness of SAOKE format, the
valuableness of SAOKE data set, the effectiveness of the proposed Logician
model, and the feasibility of the methodology to apply end-to-end learning
paradigm on supervised data sets for the challenging tasks of open information
extraction.
