Document stores have become one of the key NoSQL storage solutions. They have been widely adopted in different domains due to their ability to store semi-structured data and expressive query capabilities. However, implementations differ in terms of c

Mobile Multi-Robot Systems (MMRSs) are an emerging class of systems that are composed of a team of robots, various devices (like movable cameras, sensors) which collaborate with each other to accomplish defined missions. Moreover, these systems must

Motivated by the continuing interest in the tree data model, we study the expressive power of downward navigational query languages on trees and chains. Basic navigational queries are built from the identity relation and edge relations using composit

General dynamic Yannakakis: conjunctive queries with theta joins under updates

Autor: Wolfgang Lehner, Stijn Vansummeren, Muhammad Idris, Martín Ugarte, Hannes Voigt

Publikováno v: The VLDB journal

The ability to efficiently analyze changing data is a key requirement of many real-time analytics applications. In prior work, we have proposed general dynamic Yannakakis (GDyn), a general framework for dynamically processing acyclic conjunctive quer

Writing is a crucial skill in our society, which is regularly exerted by students across all disciplines. Automated essay scoring and automatic writing evaluation systems can support professors in the evaluation of written texts and, conversely, help
