Distributed task scheduling with security and outage constraints in MapReduce

2017

The emergence of MapReduce, a simple software framework, is helping to deal with vast amount of data (multiterabyte data-sets) in-parallel on large clusters (thousands of nodes) of commodity hardware in a reliable, fault-tolerant manner. Extensive …

Multi-view Knowledge Graph Embedding for Entity Alignment

2019 · arXiv (Cornell University)

We study the problem of embedding-based entity alignment between knowledge graphs (KGs). Previous works mainly focus on the relational structure of entities. Some further incorporate another type of features, such as attributes, for refinement. However, …

Parallelization implementation of Bayesian algorithms based on Spark platform

2019

With the rapid development of Internet technology, all kinds of data are growing exponentially. How to effectively manage and utilize these data has become the focus of research in the era of big data. Under …

Implicit Relation Linking for Question Answering over Knowledge Graph

2022 · Findings of the Association for Computational Linguistics: ACL 2022

Relation linking (RL) is a vital module in knowledge-based question answering (KBQA) systems. It aims to link the relations expressed in natural language (NL) to the corresponding ones in knowledge graph (KG). Existing methods mainly …

$μ\text{KG}$: A Library for Multi-source Knowledge Graph Embeddings and Applications

2022 · arXiv (Cornell University)

This paper presents $μ\text{KG}$, an open-source Python library for representation learning over knowledge graphs. $μ\text{KG}$ supports joint representation learning over multi-source knowledge graphs (and also a single knowledge graph), multiple deep learning libraries (PyTorch and …

Lifelong Embedding Learning and Transfer for Growing Knowledge Graphs

2022 · arXiv (Cornell University)

Existing knowledge graph (KG) embedding models have primarily focused on static KGs. However, real-world KGs do not remain static, but rather evolve and grow in tandem with the development of KG applications. Consequently, new facts …

Substation Project Evaluation Model Based on Coefficient of Variation And Fuzzy Comprehensive Evaluation

2022 · 2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)

Aiming at the problems of single traditional index, fuzzy evaluation result and subjective index weight in evaluating the investment benefit of substation project, a substation project evaluation model based on coefficient of variation and fuzzy …

Work in Progress: A Glance at Social Media Self-Censorship in North America

2023

There is a growing trend of social backlash and ostracism for thoughts and opinions shared online. Coupled with the rise of strict content moderation or digital nudges discouraging unpopular opinions, this trend calls into question …

Database security intrusion behavior identification method based on mapping deep learning

2023

In order to solve the problem of database security intrusion identification and rationally plan the query path of database index, a method of database security intrusion identification based on mapping deep learning is proposed. A …
