The International Conference on Web Services (ICWS) has been a prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of Web-based services, to identify emerging research topics, and to define the future of Web-based services. Areas include services modeling, development, publishing, discovery, recommendation, composition, testing, adaptation, and delivery, and Web services applications and standards. All topics relevant to Internet/Web based services are of interest. ICWS will organize refereed paper reviews in 8 research areas (themes): [Special Track] Generative AI in Web Services LLM and Multimodal Models enhanced service discovery, selection, composition LLM-driven service recommendation: algorithms, models, and performance Service Reasoning with Generative AI Approaches Generative AI as a Service (GaaS) Reinforcement Learning and Transformer Models for Web Services Security and Privacy in Generative AI-Driven Systems Innovative Applications of Generative AI in Web Services [Special Track] Datasets & Benchmarking for Service Computing Community Development and sharing of standard datasets Establishment of reliable and meaningful benchmarks Techniques for dataset creation, pre-processing, curation, and management in service computing Novel methodologies for performance evaluation using established benchmarks Service Discovery, Selection and Recommendation Service publishing Service search engines Collaborative filtering Service recommendation Service reasoning Machine/Deep learning powered service discovery Services Composition Automatic service composition Scientific workflows Business process integration and management Service coordination and cooperation Service-based data integration Data-driven service composition Knowledge-driven service composition Service orchestration and choreography for the future Internet Services QoS Management Quality-of-Service (QoS) modeling and management Service QoS evaluation and prediction Autonomic services Web services testing Performance aspects of cloud and service virtualization Service level agreements Services Security, Privacy and Trust Internet service security Privacy and trust Dependable and secure services Service auditing Service policy control Policy, regulation and governance & Servitization Service Applications beyond the Web Web Services for the Internet of Things (IoT) Services in Cyber-Physical Systems (CPS) Social networks and services Cloud services Edge services Mobile web services XaaS (everything as a service) Service-based processing and querying Service-based recommendation and prediction Crowdsourcing Services, Conversational Services Metaverse/VR/AR services Services for Artificial Intelligence (Smart) Cybersecurity services Other applications Service Oriented Systems Service-Oriented Architecture (SOA) Service specification and modeling Service evolution Service Oriented Software Engineering methodologies Formal methods in services Software engineering for adaptive service-oriented systems Secure service lifecycle development
