Answering complex questions over knowledge bases (KB-QA) faces huge input data with
billions of facts, involving millions of entities and thousands of predicates. For efficiency, QA …

This paper offers an in-depth exploration of semantic communications, focusing on its
integral role in wireless networks. We dissect its foundational architecture and the key …

Artificial Intelligence (AI) and Machine Learning (ML) are becoming common in our daily
lives. The AI-driven processes significantly affect us as individuals and as a society …

The increasing availability and usage of Knowledge Graphs (KGs) on the Web calls for
scalable and general-purpose solutions to store this type of data structures. We propose …

We introduce a dynamic data structure for the compact representation of binary relations R⊆
A× B. The data structure is a dynamic variant of the k 2-tree, a static compact representation …

With Knowledge Graph (KG) increasingly applied in various fields, the integration of KG has
gained significant attention to augment the knowledge-specific task capabilities of language …

Data trees, typically encoded in JSON, are ubiquitous in data-driven applications. This
ubiquity makes urgent the development of novel techniques for querying heterogeneous …
