bigNOMICS seminar: VALENTINA PRESUTTI (CNR) and ALDO GANGEMI (University of Bologna)

On Tuesday January 22nd, 2019 the Centre for Advanced Studies will host VALENTINA PRESUTTI (CNR) and ALDO GANGEMI (Bologna). The title of their seminar is "Knowledge graph engineering with ontology patterns" and will take place 11am-1pm in the ground floor seminar room of building 46i.

 

Abstract:

Knowledge graphs have become among the most important assets and key components of artificial intelligence applications. For example Google Now, Siri, Alexa and the most popular AI assistants use knowledge graphs as their background knowledge for assisting humans in their daily tasks. The key features of knowledge graphs are the “entity-based” and the “linking” paradigms: the first means that potentially everything in the world is represented as a node in the graph, and described by specific properties, the second means that these entities can be linked to each other, even if they belong to different knowledge graphs. The concept of knowledge graph on the web has been introduced and studied as part of the broader Semantic Web vision, which led to the creation of the biggest open knowledge graph existing on the web: the linked open data cloud. In the Semantic Web context, the terms used for knowledge graphs are “ontology”, referring to the formal model and its vocabulary used for encoding them, and “web of data” or “linked data”, to refer to the actual data that populate the ontology. A knowledge graph combines both ontologies and linked data.

We present and discuss good practices and methods for building high quality knowledge graphs. More specifically, we focus on how to engineer ontologies with ontology patterns, to support their reuse and interoperability. We also show how to extract structured knowledge graphs from natural language text. We will provide examples in the financial domain, including the “Financial Industry Business Ontology” (FIBO), and some related ontology patterns

 

Short bio of the speakers

 

Aldo Gangemi is full professor at University of Bologna [1], and associate researcher at Italian National Research Council, Rome. He has co-founded the Semantic Technology Lab (STLab) at ISTC-CNR in 2008. His research focuses on Semantic Technologies as an integration of methods from Knowledge Engineering, the Semantic Web, Linked Data, Cognitive Science, and Natural Language Processing. His theoretical interests concentrate upon the representation and discovery of knowledge patternsacross data, ontologies, natural language, and cognition. Applications domains include Cultural Heritage, Medicine, Law, eGovernment, Agriculture and Fishery, and Business. He has published more than 250 papers [2] in international peer-reviewed journals, conferences and books, and seats as EB member of international journals (Semantic Web, Applied Ontology, J. of Web Semantics), conference chair (LREC2006, EKAW2008, WWW2015, ESWC2018), and advisory committee member for international organizations. He has worked in the EU projects: Galen, WonderWeb, OntoWeb, Metokis, NeOn, BONy, IKS, and MARIO. Some of STLab software projects (e.g. FRED, Aemoo, Semantic Scout, Sentilo, XDTools, etc.) in ontology engineering, knowledge extraction and exploratory search are demonstrated in web applications or services [3].

Valentina Presutti is a researcher at the Institute of Cognitive Sciences and Technologies of the National Research Council (Italy) [1]. In 2008, she co-founded the Semantic Technology Laboratory (STLab) [2] that she coordinates since 2015. She earned her PhD from University of Bologna in 2006, then moved at CNR as a post-doctoral researcher and then became a permanent researcher, in 2010. Her research focuses on ontology design patterns, knowledge graphs, knowledge extraction, natural language understanding, empirical study of the semantic web, common sense knowledge extraction, social robotics and software engineering. She has published more than 100 papers [3] in international peer-reviewed journal, conferences and books (h-index 28), and serves in the Editorial Board of international journals such as Semantic Web, Intelligenza Artificiale, Data Intelligence, Journal of Web Semantics, Journal of the Association for Information Science and Technology. She has been conference chair for ESWC 2014, program chair for ESWC 2013, I.Semantics 2012, ISWC 2018 (Resources track). She is co-director of the International Semantic Web Research Summer School [4]. She’s worked in EU projects: MARIO (unit coordinator), IKS (unit coordinator), NeOn, and participated in several software project development [5].
