Workshop on Applications of Software Agents - WASA

 Software agent technologies reached a certain level of maturity that allows development of applications spanning from lab prototypes to mature real-life systems, in domains that could have not been imagined before. Furthermore, software agent technologies proved their usefulness in synergy with methods of intelligent computing and artificial intelligence.
 The aim of the WASA series of workshops is to contribute to the advancement of technologies and applications of software agents' with a special interest in intelligent computing including, but not limited to reasoning, semantics, pattern recognition, learning and cognition, etc. See the Topics section for more information on the web page for WASA:

Special Session on New Methods and Tools for Big Data
and Semantic Analytics on the Web (MT4BD-2019)

 The provision of large amounts of data from various sources (the Web, Social Media, Application Logs, Data Warehouses, Sensors, Mobiles, Open Data, etc.) is now emerging into the collection and processing of "Big Data". While Big Data notion is adopted by both academic and enterprise communities, there is currently a wide gap between its potential and its realization. Variety, velocity, scale, complexity, interpretation and security problems with Big Data raise challenges at all phases of the pipeline that can extract information and knowledge from it. The Semantic Web can offer a well-studied toolbox that can address Big Data requirements and contribute towards their meaningful analysis. Still, there are often issues that need to be tackled with like bootstrapping, efficiency and standardized business processes for semantic analytics to achieve satisfactory results. To this end, machine- and deep-learning techniques, have been shown to have considerable contributions towards Big Data analytics and to overcome Semantic Web inherent limitations. Also, there is currently a shift from computational-intensive, server-side deployments, to efficient client implementations, as an effort to give everyday browsing tasks a blend of intelligence.
 Thus, there is a natural interest in using these data and technology assets to improve a variety of applications, especially in a Web environment. It is very interesting to explore how researchers utilize data-driven strategies and discover what disciplines will change because of the advent of data. With the vast amount of data now available, modern businesses are facing the challenges of storage, management, analysis, privacy, visualization, security and data integration.
 The aim of this workshop is to serve as an interdisciplinary forum for bringing together specialists from the scientific areas of Computer & Web Engineering, Data Science, Semantic Computing, Bioinformatics-Personalized Medicine, Finance and Operational Research. The focus of this workshop is on current technological advances and challenges about the development of big data-driven algorithms, methods and tools; furthermore, to investigate how semantics-aware applications can contribute towards Big Data analysis on the Web.
 Following the success of the previous four MT4BD (MT4BD2014, MT4BD2015, MT4BD2016, and MT4BD2018) aims to further promote the formation of a community around the topic and gather an increased number of researchers and practitioners.

Special Session on Reservoir Computing

 Reservoir Computing (RC) denotes a class of approaches for designing Recurrent Neural Networks aiming at very fast learning in the context of temporal data processing. Essentially, while training is limited to a simple output layer, the dynamical recurrent component is left untrained after initialization. The resulting RC methodology is nowadays widespread in the Neural Networks community, and opens many intriguing exploring possibilities under both application and theoretical viewpoints.
 This session aims at providing an ideal context for exchange of ideas and for cross-fertilization among interdisciplinary research areas that might benefit from the RC approach. This special session calls for contributions in the area of RC, ranging from application-oriented to theoretical, and from consolidated models applications to novel breakthrough pioneering results.
The topics covered by this special session include, but are not limited to, the following:
  • Echo State Networks and Liquid State Machines
  • Challenging applications of Reservoir Computing, including Big Data, embeddable systems, and industrial processes
  • Novel Reservoir Computing models
  • Theoretical analysis of Reservoir Computing

Special Session on Machine Learning : Methodologies, Applications and Trends

 Artificial Intelligence (AI) has been applied successfully to many fields such as data analysis, finance, multimedia, signal and image processing, web technologies, robotics, and automations, etc. Machine learning, as a major technology behind AI, is changing the world rapidly by deploying varied algorithms. For example, artificial neural networks, especially those for deep learning, are implemented in real world such as the GPU computations owing to the maturity of high-speed and parallel architecture. The latter is also becoming a promising research field for further explorations. Many researches of machine learning are inspired by the developments of computational intelligence. How machine learning can be contributed to varied applications related to intelligence is the main focus of this special session.
