Crowd-sourcing Updates of Large Knowledge Graphs

Albin Ahmeti, Víctor Mireles, Artem Revenko, Marta Sabou, Martin Schauer
2018 International Semantic Web Conference  
The method is most suitable for large knowledge graphs, for which it is unreasonable for a single curator to be aware of all the existing content.  ...  Users can provide their updates in an intuitive way without requiring expertise about the knowledge already contained in the graph.  ...  As part of this project, we are designing a web-based system which collects extensions to a large knowledge graph from the crowd of citizens which use the platform 4 .  ...

RoboBrain: Large-Scale Knowledge Engine for Robots [article]

Ashutosh Saxena, Ashesh Jain, Ozan Sener, Aditya Jami, Dipendra K. Misra, Hema S. Koppula
2015 arXiv   pre-print
In this paper we introduce a knowledge engine, which learns and shares knowledge representations, for robots to carry out a variety of tasks.  ...  The knowledge stored in the engine comes from multiple sources including physical interactions that robots have while performing tasks (perception, planning and control), knowledge bases from the Internet  ...  We also thank Yun Jiang, Ian Lenz, Jaeyong Sung, and Chenxia Wu for their contributions to the knowledge for RoboBrain.  ...

Knowledge Graph Semantic Enhancement of Input Data for Improving AI

Shreyansh Bhatt, Amit Sheth, Valerie Shalin, Jinjin Zhao, Amit Sheth
2020 IEEE Internet Computing  
The term Knowledge Graph (KG) is in vogue as for many practical applications, it is convenient and useful to organize this background knowledge in the form of a graph.  ...  Intelligent systems designed using machine learning algorithms require a large number of labeled data.  ...  The knowledge graph is updated based on the results and the application-specific objective optimization is then run for a KG, which leads to an improved (application-specific) representation of the KG.  ...

Efficient Reasoning upon Fusion of Many Data Sources

Chase Alexander Yakaboski, Eugene Santos
2021 Proceedings of the ... International Florida Artificial Intelligence Research Society Conference  
Past research has focused on knowledge fusion situations that only involve a limited number of sources.  ...  Bayesian Knowledge Bases (BKB), a graphical model for representing structured probabilistic information, allow for efficient fusion of knowledge from multiple sources.  ...  As I-nodes are random variable instantiations, then Reproduce Ability = Low and Over Crowd = No would be examples of I-nodes in our correlation graph.  ...

Arnold: Declarative Crowd-Machine Data Integration

Shawn R. Jeffery, Liwen Sun, Matt DeLand, Nick Pendar, Rick Barber, Andrew Galdi
2013 Conference on Innovative Data Systems Research  
Human input, or crowd-sourcing, is an effective tool to help produce such high-quality data. It is infeasible, however, to involve humans at every step of the data cleaning process for all data.  ...  We have developed a declarative approach to data cleaning and integration that balances when and where to apply crowd-sourcing and machine computation using a new type of data independence that we term  ...  When utilizing crowd-sourcing at large scale, however, such knowledge is largely inaccessible to an application developer.  ...

Multi-objective clustering algorithm using particle swarm optimization with crowding distance (MCPSO-CD)

Alwatben Batoul Rashed, Hazlina Hamdan, Nurfadhlina Mohd Sharef, Md Nasir Sulaiman, Razali Yaakob, Mansir Abubakar
2020 IJAIN (International Journal of Advances in Intelligent Informatics)  
According to the literature, crowding distance is one of the most efficient algorithms that was developed based on density measures to treat the problem of selection mechanism for archive updates.  ...  Generally, clustering is difficult and complex phenomenon, where the appropriate numbers of clusters are always unknown, comes with a large number of potential solutions, and as well the datasets are unsupervised  ...  Archive update Crowding distance is first sorted in ascending order of the computed objective function values of the set of solutions.  ...

Fault-Tolerant Entity Resolution with the Crowd [article]

Anja Gruenheid and Besmira Nushi and Tim Kraska and Wolfgang Gatterbauer and Donald Kossmann
2015 arXiv   pre-print
Although the crowd generates insightful information especially for complex problems such as entity resolution (ER), the output quality of crowd workers is often noisy.  ...  The challenge that we address in this paper is how to minimize the cost for task requesters while maximizing ER result quality under the assumption of unreliable input from the crowd.  ...  Knowledge Graph [31] or the Facebook Entities Graph [32] .  ...

Chansoo Kim, Sungjin Cho, Myoungho Sunwoo, Paulo Resende, Benazouz Bradaï, Kichun Jo
2022 Journal of Advanced Transportation  
Unfortunately, a point cloud map occupies too large data size to transmit data in the uploading and downloading of the map update framework.  ...  The proposed GND map update framework comprises two parts: map change detection based on crowd-sourcing vehicles and map updating based on a map cloud server.  ...  However, to the best of our knowledge, no crowd-sourced data-based map update systems currently exist for other geometric map structures.  ...
