The Graph Language: How Knowledge Graphs Speak to Large Language Models
Giuseppe Pirrò
Large Language Models (LLMs) excel at reasoning but benefit from grounding provided by Knowledge Graphs (KGs). However, integrating these paradigms is challenging. We introduce GRA…
Fact Checking via Path Embedding and Aggregation
Giuseppe Pirrò
Knowledge graphs (KGs) are a useful source of background knowledge to (dis)prove facts of the form (s, p, o). Finding paths between s and o is the cornerstone of several fact-check…
Toward Edge-Centric Network Embeddings
Giuseppe Pirrò
Existing network embedding approaches tackle the problem of learning low-dimensional node representations. However, networks can also be seen in the light of edges interlinking pai…
A hierarchical approach for modelling X-ray beamlines. Application to a coherent beamline
Manuel Sanchez del Rio, Rafael Celestre, Mark Glass +7
We consider different approaches to simulate a modern X-ray beamline. Several methodologies with increasing complexity are applied to discuss the relevant parameters that quantify…
Triple2Vec: Learning Triple Embeddings from Knowledge Graphs
Valeria Fionda, Giuseppe Pirró
Graph embedding techniques allow to learn high-quality feature vectors from graph structures and are useful in a variety of tasks, from node classification to clustering. Existing…
From Community Detection to Community Deception
Valeria Fionda, Giuseppe Pirrò
The community deception problem is about how to hide a target community C from community detection algorithms. The need for deception emerges whenever a group of entities (e.g., ac…
A Context-Based Semantics for SPARQL Property Paths over the Web (Extended Version)
Olaf Hartig, Giuseppe Pirro
As of today, there exists no standard language for querying Linked Data on the Web, where navigation across distributed data sources is a key feature. A natural candidate seems to…
Web Maps and Their Algebra
Valeria Fionda, Claudio Gutierrez, Giuseppe Pirró
A map is an abstract visual representation of a region, taken from a given space, usually designed for final human consumption. Traditional cartography focuses on the mapping of Eu…
Semantic Navigation on the Web of Data: Specification of Routes, Web Fragments and Actions
Valeria Fionda, Claudio Gutierrez, Giuseppe Pirró
The massive semantic data sources linked in the Web of Data give new meaning to old features like navigation; introduce new challenges like semantic specification of Web fragments;…
