Sogou Takes a Top Spot at NLPCC 2020

BEIJING,July 1,2020 -- Sogou Inc. (NYSE: SOGO) ("Sogou" or "the Company"),an innovator in search and a leader in China's internet industry,today announced it ranked first in the Auto Information Extraction (AutoIE) shared task at the 9th CCF International Conference on Natural Language Processing and Chinese Computing (NLPCC 2020),demonstrating Sogou's industry-leading capabilities in Natural Language Processing (NLP).

Founded by the China Computer Federation (CCF) in 2012,NLPCC is China's leading annual conference specialized in the field of NLP. As a fundamental technology in NLP,Information Extraction (IE) refers to the extraction of structured information such as names,events,places,and their relations and attributes from unstructured texts. Accurate extraction therefore enables a more effective analysis and understanding of complicated,unlabeled data.

Sogou's IE model ranked first in the AutoIE shared task for the highest accuracy rate of information extracted. By leveraging a combined Bert-CRF model with incomplete annotation training and self-training,the Sogou team developed an IE model capable of extracting highly accurate information from unstructured sources—despite incomplete annotations and unlabeled texts.

Sogou's advanced IE capability will further strengthen its knowledge graph technology,which has been widely used in its portfolio of products and services to categorize,extract,and restructure an enormous amount of information. A knowledge graphis the structure and representation of a knowledge base as a graph with a network of datapoints linked by relations. Sogou Search is the first search engine in China to apply knowledge graphs to help users find better answers to their queries. In addition,Sogou adopts knowledge graphs in its Simultaneous Interpretation 3.0,the latest generation of Sogou's AI-powered simultaneous interpretation solution,to generate contextual knowledge and collect background information that can provide real-time understanding and interpretation as a speaker talks.

Sogou will further leverage its industry-leading IE capabilities as part of its applications of AI,including in its Q&A systems,Recommendation Service,and Healthcare Search.
