Towards a Gateway for Knowledge Graph Schemas Collection, Analysis, and Embedding

no code implementations21 Nov 2023 Mattia Fumagalli, Marco Boffo, Daqian Shi, Mayukh Bagchi, Fausto Giunchiglia

One of the significant barriers to the training of statistical models on knowledge graphs is the difficulty that scientists have in finding the best input data to address their prediction goal.

Integrating 3D City Data through Knowledge Graphs

no code implementations17 Oct 2023 Linfang Ding, Guohui Xiao, Albulen Pano, Mattia Fumagalli, Dongsheng Chen, Yu Feng, Diego Calvanese, Hongchao Fan, Liqiu Meng

Moreover, embracing KGs makes it easier to integrate with other spatial data sources, e. g., OpenStreetMap and existing (Geo)KGs (e. g., Wikidata, DBPedia, and GeoNames), and to perform queries combining information from multiple data sources.

Towards Ranking Schemas by Focus

no code implementations27 Feb 2023 Mattia Fumagalli, Daqian Shi, Fausto Giunchiglia

The main goal of this paper is to evaluate knowledge base schemas, modeled as a set of entity types, each such type being associated with a set of properties, according to their focus.

Popularity Driven Data Integration

no code implementations28 Sep 2022 Fausto Giunchiglia, Simone Bocca, Mattia Fumagalli, Mayukh Bagchi, Alessio Zamboni

The intuition is that data will be treated differently based on their popularity: the more a certain set of data have been reused, the more they will be reused and the less they will be changed across reuses, thus decreasing the overall data preprocessing costs, while increasing backward compatibility and future sharing

LiveSchema: A Gateway Towards Learning on Knowledge Graph Schemas

no code implementations13 Jul 2022 Mattia Fumagalli, Marco Boffo, Daqian Shi, Mayukh Bagchi, Fausto Giunchiglia

In this paper, we describe the LiveSchema initiative, namely a gateway that offers a family of services to easily access, analyze, transform and exploit knowledge graph schemas, with the main goal of facilitating the reuse of these resources in machine learning use cases.

iTelos -- Purpose Driven Knowledge Graph Generation

no code implementations19 May 2021 Fausto Giunchiglia, Simone Bocca, Mattia Fumagalli, Mayukh Bagchi, Alessio Zamboni

When building a new application we are more and more confronted with the need of reusing and integrating pre-existing knowledge, e. g., ontologies, schemas, data of any kind, from multiple sources.
