BEIJING, Jan. 7, 2019 /PRNewswire/ -- Sogou Inc. today
announced that Sogou Search AI Group ranked first in the
Conversational Question Answering (CoQA) Challenge, with an overall
score of 82.8%, which surpassed the previous record held by
Microsoft and further narrowed the gap with human performance
(88.8%).
Launched by Stanford University in
August 2018, CoQA is a large-scale
dataset for building Conversational Question Answering systems. The
goal of the CoQA challenge is to measure the ability of machines to
understand a text passage and answer a series of interconnected
questions that appear in a conversation. Compared with the
well-known reading comprehension dataset - SQuAD, CoQA is highly
conversational and can result in a richer variety of questions.
While nearly half of SQuAD questions are dominated by what
questions, the distribution of CoQA is spread across multiple
question types. Furthermore, SQuAD has 100% extractive answers by
design, whereas in CoQA, this rate decreased to 66.8%. Leading
companies and research institutes, including Microsoft,
Stanford University, and Tsinghua
University have also participated in the CoQA Challenge.
Sogou Search AI Group's BERT+ Answer Verification (Single
model) refreshed all the evaluation indicators of CoQA, and
further narrowed the gap between the average reading comprehension
level of a machine and a human. Sogou's algorithm model can
comprehensively consider the answer extraction, and integrate
dialogue history and previous QA information, thus greatly
improving a machine's understanding of the question and the
accuracy of the answer.
Intuitive Q&A is the future of search. With advances in AI
and machine learning, Sogou search technology can accurately
analyze user queries and provide reliable answers that are sourced
from a vast database of authoritative information.
Sogou has already applied this leading Q&A technology to its
product and service portfolio. The Company's healthcare search
service, Sogou Mingyi, offers an AI-powered "smart diagnosing
assistant" for patients by imitating patient-doctor conversations.
After users answer a series of Q&As, Sogou Lawyer, the
Company's legal search service, can analyze the information and
provide legal advice, a prediction of the case outcome, and
references to similar cases.
Sogou continuously pushes the boundaries of AI and the
development of more innovative and practical applications of
intuitive Q&A to help users in fields such as healthcare, law,
and other verticals.
