Great efforts have been dedicated to harvesting knowledge bases from online encyclopedias. [] Key Method To solve these challenges, we propose a never-ending Chinese Knowledge extraction system, CN-DBpedia, which can automatically generate a knowledge base that is of ever-increasing in size and constantly updated. Specially, we reduce the human costs by reusing the ontology of existing knowledge bases and building an end-to-end facts extraction model.
CN-DBpedia2: An Extraction and Verification Framework for Enriching Chinese Encyclopedia Knowledge Base
TLDR
An extraction and verification framework to enrich the knowledge bases and builds a new version of knowledge base CN-DBpedia2, which additionally contains the high confidence facts extracted from the description texts of entities.
Knowledge graph construction from multiple online encyclopedias
TLDR
Experimental results show that the approaches for knowledge extraction and linking outperform state-of-the-art baselines in different evaluation metrics, and the framework can generate a large-scale knowledge graph after inputting multiple online encyclopedias.
IFTA: Iterative filtering by using TF-AICL algorithm for Chinese encyclopedia knowledge refinement
TLDR
The precision, recall and F-measure results on the BaiduBaike and Hudong datasets indicate that the refining effects on open-domain Chinese encyclopedia KBs by the IFTA method outperform the state-of-the-art methods.
Research on Automatic Question Answering of Generative Knowledge Graph Based on Pointer Network
TLDR
A new generative question answering method based on knowledge graph is proposed, including three parts of knowledge vocabulary construction, data pre-processing, and answer generation, which can achieve superior performance on WebQA datasets than other methods.
Towards the Completion of a Domain-Specific Knowledge Base with Emerging Query Terms
TLDR
This paper uses the product knowledge base in the largest Chinese e-commerce platform, Taobao, as an example to investigate a completion procedure of a domain-specific knowledge base, and proposes a graph based solution to overcome many challenges.

Enabling Language Representation with Knowledge Graph and Structured Semantic Information
TLDR
Sem-K-BERT is proposed, which integrates the information of KG and semantic role labeling before and after the BERT encoding layer, and introduces a context-aware knowledge screening mechanism based on semantic correlation calculation and a text-semantic alignment mechanism to effectively integrate the two external information and reduce the impact of noise.

CLEEK: A Chinese Long-text Corpus for Entity Linking
TLDR
This work builds CLEEK, a Chinese corpus of multi-domain long text for entity linking, in order to encourage advancement of entity linking in languages besides English, and devise a measure to evaluate the difficulty of documents with respect to entity linking.
Decoding Chinese User Generated Categories for Fine-Grained Knowledge Harvesting
TLDR
This paper introduces two word embedding projection models to identify is-a relations and proposes a graph clique mining algorithm to harvest non-taxonomic relations from UGCs, together with their textual patterns.
