Learning Disentangled Semantic Representations for Zero-Shot Cross-Lingual Transfer in Multilingual Machine Reading Comprehension
Linjuan Wu, Shaojuan Wu, Xiaowang Zhang +4
Multilingual pre-trained models are able to zero-shot transfer knowledge from rich-resource to low-resource languages in machine reading comprehension (MRC). However, inherent ling…
Modeling Global Semantics for Question Answering over Knowledge Bases
Peiyun Wu, Yunjie Wu, Linjuan Wu +2
Semantic parsing, as an important approach to question answering over knowledge bases (KBQA), transforms a question into the complete query graph for further generating the correct…
Service Ecosystem: A Lens of Smart Society
Xiao Xue, ZhiYong Feng, ShiZhan Chen +8
Intelligence services are playing an increasingly important role in the operation of our society. Exploring the evolution mechanism, boundaries and challenges of service ecosystem…
Value Entropy Model: Metric Method of Service Ecosystem Evolution
Xiao Xue, Zhaojie Chen, Shufang Wang +3
With the development of cloud computing, service computing, IoT(Internet of Things) and mobile Internet, the diversity and sociality of services are increasingly apparent. To meet…
Value driven Analysis Framework of Service Ecosystem Evolution Mechanism
Xiao Xue, Deyu Zhou, Yaodan Guo +3
With the development of cloud computing, service computing, IoT(Internet of Things) and mobile Internet, the diversity and sociality of services are increasingly apparent. To meet…
An Android Application Risk Evaluation Framework Based on Minimum Permission Set Identification
Jianmao Xiao, Shizhan Chen, Qiang He +2
Android utilizes a security mechanism that requires apps to request permission for accessing sensitive user data, e.g., contacts and SMSs, or certain system features, e.g., camera…
Towards Universal Languages for Tractable Ontology Mediated Query Answering
Heng Zhang, Yan Zhang, Jia-Huai You +2
An ontology language for ontology mediated query answering (OMQA-language) is universal for a family of OMQA-languages if it is the most expressive one among this family. In this p…
SCC-rFMQ Learning in Cooperative Markov Games with Continuous Actions
Chengwei Zhang, Xiaohong Li, Jianye Hao +5
Although many reinforcement learning methods have been proposed for learning the optimal solutions in single-agent continuous-action domains, multiagent coordination domains with c…
gSMat: A Scalable Sparse Matrix-based Join for SPARQL Query Processing
Xiaowang Zhang, Mingyue Zhang, Peng Peng +3
Resource Description Framework (RDF) has been widely used to represent information on the web, while SPARQL is a standard query language to manipulate RDF data. Given a SPARQL quer…
TrQuery: An Embedding-based Framework for Recommanding SPARQL Queries
Lijing Zhang, Xiaowang Zhang, Zhiyong Feng
In this paper, we present an embedding-based framework (TrQuery) for recommending solutions of a SPARQL query, including approximate solutions when exact querying solutions are not…
MapSQ: A MapReduce-based Framework for SPARQL Queries on GPU
Jiaying Feng, Xiaowang Zhang, Zhiyong Feng
In this paper, we present a MapReduce-based framework for evaluating SPARQL queries on GPU (named MapSQ) to large-scale RDF datesets efficiently by applying both high performance.…
hMDAP: A Hybrid Framework for Multi-paradigm Data Analytical Processing on Spark
Xiaowang Zhang, Jiahui Zhang, Zhiyong Feng
We propose hMDAP, a hybrid framework for large-scale data analytical processing on Spark, to support multi-paradigm process (incl. OLAP, machine learning, and graph analysis etc.)…
PRSP: A Plugin-based Framework for RDF Stream Processing
Qiong Li, Xiaowang Zhang, Zhiyong Feng
In this paper, we propose a plugin-based framework for RDF stream processing named PRSP. Within this framework, we can employ SPARQL query engines to process C-SPARQL queries with…
Path discovery by Querying the federation of Relational Database and RDF Graph
Xiaowang Zhang, Jiahui Zhang, Muhammad Qasim Yasin +2
The class of queries for detecting path is an important as those can extract implicit binary relations over the nodes of input graphs. Most of the path querying languages used by t…
PIWD: A Plugin-based Framework for Well-Designed SPARQL
Xiaowang Zhang, Zhenyu Song, Zhiyong Feng +1
In the real world datasets (e.g.,DBpedia query log), queries built on well-designed patterns containing only AND and OPT operators (for short, WDAO-patterns) account for a large pr…
RORS: Enhanced Rule-based OWL Reasoning on Spark
Zhihui Liu, Zhiyong Feng, Xiaowang Zhang +2
The rule-based OWL reasoning is to compute the deductive closure of an ontology by applying RDF/RDFS and OWL entailment rules. The performance of the rule-based OWL reasoning is of…
Efficient Approximation of Well-Designed SPARQL Queries
Zhenyu Song, Zhiyong Feng, Xiaowang Zhang +2
Query response time often influences user experience in the real world. However, it possibly takes more time to answer a query with its all exact solutions, especially when it cont…
