Title: Deep Knowledge Graph Reasoning Time:8:30 – 10:00 Abstract: Learning to reason and understand the world’s knowledge is a fundamental problem in Artificial Intelligence (AI). The core research question that I will address in this tutorial is the following: how can we design scalable statistical learning and inference methods to operate over rich knowledge representations? In this tutorial, I will describe some recent studies on learning to reason in large scale knowledge graphs (KGs). More specifically, I will introduce both path-based and embedding-based approaches. Then, I will introduce DeepPath, a novel deep reinforcement learning framework for learning multi-hop relational paths: it uses a policy-based agent with continuous states based on knowledge graph embeddings, which reasons in a KG vector space by sampling the most promising relation to extend its continuous states based on knowledge graph embeddings, which reasons in a KG vector space by sampling the most promising relation to extend its path. To conclude, I will also some of our initial attempts of bridging path-finding and path-reasoning in a principled variational inference framework.

Title: Exploiting and Reasoning With Open Knowledge Graph Time:10:30-12:00 Abstract: While domain specific knowledge graphs are useful within specific domains, open knowledge graphs such as DBPedia, YAGO and Wikidata, have recently played instrumental roles in a number of applications. They can used as common sense knowledge for machine learning applications. They can also serve as reusable knowledge to complement domain specific knowledge graphs. In this tutorial, we will (1) introduce some well known open knowledge graphs, including DBPedia, YAGO and Wikidata, and their applications, and (2) survey on existing reasoning techniques for large scale open knowledge graphs. This tutorial is designed for a general semantic technology practitioner, whether from research or industry. Participants will only be expected to have basic knowledge of semantic technologies. Bio:Prof Dr Jeff Z. Pan leads the Knowledge Technology group in the Department of Computing Science at University of Aberdeen. His research focuses primarily on knowledge representation, artificial intelligence and data science, in particular knowledge graph construction and maintenance, large-scale ontology reasoning, stream reasoning, question answering, and combining ontology reasoning with machine learning, as well as their applications. He is a key contributor of the W3C OWL (Web Ontology Language) standard. He leads the development of the award-wining TrOWL reasoner, the only ontology reasoner that Oracle Spatial and Graph (from v12) uses via the OWL-DBC database connection. He is an internationally leading expert on Knowledge Graph, being the Chief Editor of the first two books on Knowledge Graph, a new technology that is widely used by world leading IT companies. As the Chief Scientist and Coordinator of the EU Marie-Curie K-Drive project, he coordinated 22 Marie Curie Fellows on Knowledge Graph and Ontology research. He is an Associate Editor of the Journal of Web Semantics (JWS) and of the International Journal on Semantic Web and Information Systems (IJSWIS). He actively teams up with industrial collaborators on innovative research

Title: Deep Learning for Natural Language Inference Time:13:30-17:00 Abstract: Reasoning and inference are central to both human and artificial intelligence (AI). Modeling inference in natural language is notoriously challenging but is a basic problem towards true natural language understanding, as pointed out by MacCartney and Manning (2008), “a necessary (if not sufficient) condition for true natural language understanding is a mastery of open-domain natural language inference.” In this tutorial, I will introduce the state-of-the-art deep learning models for natural language inference (NLI). The tutorial will start with even more fundamental problems: semantic representation and composition, to lay the basis for the tutorial and our discussion. The tutorial will then focus not only on how deep learning models achieve the state-of-the-art performance but also on the limitations.

Dr. Zhu is an Associate Editor of the Computational Intelligence journal. He also served on many academic committees, e.g., as the Publication Chair for COLING-2018, Area Chair of ACL-2018 and COLING-2018, and Steering Committee Member of SemEval-2018. Dr. Zhu is a panel member of Canada NSERC Discovery Grants (Computer Science; year 2017, 2020, 2021). He also served as an external reviewer for many government grants in Canada (e.g., NSERC), Singapore, and Hong Kong (e.g., GRF). Dr. Zhu also helps assess start-up companies’ proposals for seed-stage programs. In the past, he worked with top government research lab (e.g., NRC) and industrial research labs such as Google (New York), IBM T.J. Watson Research Center, and Intel China Research Center.

Title:  Semantic Relation Extraction from Text Time:8:30-12:00 Abstract: Every non-trivial text describes interactions and relations between people, institutions, activities, events and so on. What we know about the world consists in large part of such relations, and that knowledge contributes to the understanding of what texts refer to. Newly found relations can in turn become part of this knowledge that is stored for future use. To grasp a text’s semantic content, an automatic system must be able to recognize relations in texts and to reason about them. This may be done by applying and updating previously acquired knowledge. We focus here in particular on semantic relations that describe the interactions between nouns and compact noun phrases, and we present such relations from both a theoretical and a practical perspective. The theoretical exploration sketches the historical path that has brought us to the contemporary view and interpretation of semantic relations. We discuss a wide range of relation inventories proposed by linguists and by language processing people. Such inventories vary by domain, granularity and suitability for downstream applications. On the practical side, we investigate the recognition and acquisition of relations from texts. In a look at supervised learning methods, we present some of the available datasets, the variety of features that can describe relation instances, and some learning algorithms found appropriate for the task, including recent feature-less deep learning approaches. Next, we present weakly supervised and unsupervised learning methods of acquiring relations from large corpora with little or no previously annotated data. We show how enduring the bootstrapping algorithm based on seed examples or patterns has proved to be, and how it has been adapted to tackle Web-scale text collections. We also show a few machine learning techniques that can perform fast and reliable relation extraction by taking advantage of data redundancy and variability.
