Reflections on the State of Semantics and Semantic Computing

Abstract: During the past decade, the role of semantic computing has grown from a novelty to a mainstream technology. Where once youthful enthusiasm, supported by broadly-based claims of lightly-verified impact, dominated most research results, the time seems ripe for a new era of academic responsibility and rigor. In this talk, we reflect on three areas of semantic computing and look at past results and future potential. Using the human body as a framework, we consider problems of semantic reasoning (the head), of content-based perception (the nervous system) and the study of the emotional limitations of the machine (the heart). Our goal in each area is to contrast past work with the paths and needs for both a more robust technology and a more robust society.

Bio: Dick Bulterman is Fellow at CWI: the Center Mathematics and Computer Science in Amsterdam, where he has held numerous positions since 1988. He is also Emeritus Professor of Computer Science at the Vrije Universiteit, also in Amsterdam. He is also the Chair of the ACM Web Conference steering committee. In addition to his appointment at CWI and the VU, Bulterman and founder and managing director of Oratrix Development in Amsterdam and was President/CEO of FXPAL in Palo Alto. His research has concentrated on computer networking, temporal specification languages and systems to support the creation and deployment of rich media content across the public Internet. He is former Chair of ACM SIGWEB and has served in multiple capacities for ACM SIGMM. He was the recipient of the SIGMM Lifetime Technical Achievement Award in 2014. He has been associate editor of every major journal in his research areas and has been general chair or program chair for over a dozen international events. He has been a frequent speaker on matters of technology and society. He has been active with the IEEE International Conference on Semantic Computing for nearly a decade.

Green Learning: Introduction, Examples, and Outlook

Abstract: The rapid advances in artificial intelligence in the last decade are primarily attributed to the wide applications of deep learning (DL). Yet, the high carbon footprint yielded by larger DL networks is a concern to sustainability. Green learning (GL) has been proposed as an alternative to address this concern. GL is characterized by low carbon footprints, small model sizes, low computational complexity, and mathematical transparency.  It offers energy-effective solutions in cloud centers and mobile/edge devices.  It has three main modules: 1) unsupervised representation learning, 2) supervised feature learning, and 3) decision learning. GL has been successfully applied to a few applications. This talk provides an overview on the GL solution, its demonstrated examples, and its technical outlook. The connection between GL and DL will also be discussed.

Opportunities in Semantic Computing

Abstract: Graph representation and knowledge graphs provide unique opportunities in representing complex systems. Enterprise knowledge graphs have become increasingly popular in recent years. They are actively used in natural language processing applications, recommender systems, drug discovery, image understanding and semantic search.  Semantic networks are seen as important tools in the future of machine learning systems and AI. Reasoning over knowledge graphs enables opportunities in complementing the pattern detection capabilities of the traditional machine learning solutions with interpretability and reasoning. Knowledge graphs are frequently challenged by the size and complexity of real-world applications and face significant limitations in representing complex relationships.  In this talk, we explore the issues in representing complex, transient, uncertain real-world relationships in knowledge graphs. We argue that constraining semantic networks to purely data storage systems may be a restricting assumption. Integration of computing, memory and communication capabilities in non Von Neumann architectures provides unique opportunities in advancing graph-based system capabilities. We look at architectural and system design paradigms to explore potential solution paths towards truly semantic computing.

Large Language Models as Support for People with Disabilities

Abstract: Large Language Model technology, seen for example in GPT-3, LaMDA, or chatGPT, may provide new ways to support people with disabilities. Automatic text simplification may become practical, as well as assistance in navigating complex Web sites. Artificial personal assistants, flexible enough to deal with a useful range of situations, may be possible. The new technology may be able to meet the wide-ranging critiques of earlier systems, posed by Harold Garfinkel, Philip Agre, and Virginia Eubanks, a development with theoretical, as well as practical, implications.
