This two-volume set LNAI 7523 and LNAI 7524 constitutes the refereed proceedings of the European Conference on Machine Learning and Knowledge Discovery in Databases: ECML PKDD 2012, held in Bristol, UK, in September 2012. The 105 revised research papers presented together with 5 invited talks were carefully reviewed and selected from 443 submissions. The final sections of the proceedings are devoted to Demo and Nectar papers. The Demo track includes 10 papers (from 19 submissions) and the Nectar track includes 4 papers (from 14 submissions). The papers grouped in topical sections on association rules and frequent patterns; Bayesian learning and graphical models; classification; dimensionality reduction, feature selection and extraction; distance-based methods and kernels; ensemble methods; graph and tree mining; large-scale, distributed and parallel mining and learning; multi-relational mining and learning; multi-task learning; natural language processing; online learning and data streams; privacy and security; rankings and recommendations; reinforcement learning and planning; rule mining and subgroup discovery; semi-supervised and transductive learning; sensor data; sequence and string mining; social network mining; spatial and geographical data mining; statistical methods and evaluation; time series and temporal data mining; and transfer learning.

This volume constitutes the refereed proceedings of the workshops held at the 32nd International Conference on Database and Expert Systems Applications, DEXA 2021, held in a virtual format in September 2021: The 12th International Workshop on Biological Knowledge Discovery from Data (BIOKDD 2021), the 5th International Workshop on Cyber-Security and Functional Safety in Cyber-Physical Systems (IWCFS 2021), the 3rd International Workshop on Machine Learning and Knowledge Graphs (MLKgraphs 2021), the 1st International Workshop on Artificial Intelligence for Clean, Affordable and Reliable Energy Supply (AI-CARES 2021), the 1st International Workshop on Time Ordered Data (ProTime2021), and the 1st International Workshop on AI System Engineering: Math, Modelling and Software (AISys2021). Due to the COVID-19 pandemic the conference and workshops were held virtually. The 23 papers were thoroughly reviewed and selected from 50 submissions, and discuss a range of topics including: knowledge discovery, biological data, cyber security, cyber-physical system, machine learning, knowledge graphs, information retriever, data base, and artificial intelligence.

This edited volume traces the rise of far right vigilante movements – some who have been involved in serious violence against minorities, migrants and other vulnerable groups in society, whereas other vigilantes are intimidating but avoid using violence. Written by an international team of contributors, the book features case studies from Western Europe, Eastern Europe, North America, and Asia. Each chapter is written to a common research template examining the national social and political context, the purpose of the vigilante group, how it is organised and operates, its communications and social media strategy and its relationship to mainstream social actors and institutions, and to similar groups in other countries. The final comparative chapter explores some of the broader research issues such as under which conditions such vigiliantism emerges, flourishes or fails, policing approaches, masculinity, the role of social media, responses from the state and civil society, and the evidence of transnational co-operation or inspiration. This is a groundbreaking volume which will be of particular interest to scholars with an interest in the extreme right, social movements, political violence, policing and criminology.

TYPIX is a critical compilation of crystallographic data prepared by E. Parthé at the University of Geneva. It contains over 3200 compounds representative of the structure types found among inorganic compounds. This work contains condensed crystal chemical information about individual structure types as well as an extensive chapter on the crystal chemistry of particular structure families. The aim of the compilation is to clarify and classify published data for intermetallic and other inorganic structures (types found exclusively with halides or oxides are only included for a few special cases). It provides a tool for additional crystal chemical studies and the development of new materials.
