Virtue theory has an illustrious history as one of the most prominent philosophical traditions, and in the wake of the recent renewed focus on human practices virtue theory once again provides powerful frameworks, tools and insights. Work in such diverse fields as ethics, the philosophy of science, epistemology, philosophy of law, political theory, aesthetics, and argumentation theory shows that virtue theory permits normative discourse without imposing overly rigid criteria. Within the philosophy of mathematics, and mathematics itself, attention to virtues has a variety of sources: theoretical virtues have been put forward both to analyse the practice of proof and to justify axioms, and ethical virtues have been offered as a basis for understanding the social dimensions of mathematical practice. Indeed, some authors have advocated virtue epistemology as the correct epistemology for mathematics (and perhaps even as the basis for progress in the metaphysics of mathematics). In this topical collection we aim to consolidate and encourage this trend in the philosophy of mathematics.

The last two decades have seen extensive research on the syntax and distribution of reciprocal morphemes across languages. Typological linguists and theoretical syntacticians have revealed fascinating phenomena of reciprocity, which have substantially increased our knowledge of the ways languages encode reciprocal concepts. Quite independently, there have been some important advances in the formal semantic analysis of reciprocals in English. Yet, at present there is no clear understanding of the cross-linguistic semantics of reciprocals, or even the extent to which such a general semantics is motivated. The workshop will bring together formal semanticists and experts of reciprocity phenomena, with the goal of addressing some of the major questions in this area.

Keynote speakers are Mary Dalrymple (Oxford University) and Martin Haspelmath (MPI-SHH Jena & Leipzig University).

The purpose of this workshop is to bring together researchers from philosophy, computer science, and allied disciplines who work on non-monotonic logics and defeasible inference. The idea is to bring traditional philosophical reflections on these topics-- such as defeat in epistemology, prima facie duties in ethics, and belief revision in philosophy of science-- together with the rich tradition of non-monotonic logics in computer science and artificial intelligence, including default logic and logic programming.

This will be a 1.5 day workshop (half day Friday 11 October afternoon, full day Saturday 12 October), with approximately 30 participants, including 4 invited talks, 2-3 contributed talks, and a poster session.

Digital curation is a complex time and knowledge intensive process, in which knowledge workers create new content artifacts and knowledge insights from heterogeneous sources (content, data, knowledge). The work required for this includes, e.g., selecting, summarizing, scheduling, translating, localising, structuring, condensing, enriching, visualizing and explaining the various contents, from sources such as online newspapers, news portals, social media, linked data, business information systems, IoT data streams etc. AI, in particular from the field of language and semantic knowledge technologies, are used to support these tasks and thereby accelerate and qualitatively improve them.

The conference provides a forum on the use of digital curation technologies in application domains for, e.g., media, journalism, logistics, cultural heritage, health care and life sciences, energy, industry. Of particular relevance are papers that demonstrate the applied use of digital curation technologies and tools in domain-specific use cases and that bridge traditional boundaries between disciplines such as Artificial Intelligence and Semantic Web, data analytics and machine learning, information/content and knowledge management systems, information retrieval, knowledge discovery, and computational linguistics.

SLSP is a yearly conference series aimed at promoting and displaying excellent research on the wide spectrum of statistical methods that are currently in use in computational language or speech processing. It aims at attracting contributions from both fields. Though there exist large conferences and workshops hosting contributions to any of these areas, SLSP is a more focused meeting where synergies between the two domains will hopefully happen. In SLSP 2019, significant room will be reserved to young scholars at the beginning of their career and particular focus will be put on methodology.

SLSP 2019 will consist of invited talks, peer-reviewed contributions and posters.

Systems of connexive logic have been motivated by considerations on a content connection between the antecedent and succedent of valid implications and by applications that range from Aristotle's syllogistic to Categorial Grammar and the study of causal implications. After four workshops on connexive logics in Istanbul, Raesfeld Castle, Kyoto and Bochum, a fifth workshop on connexive logics will take place in Bochum (Germany) on the 29th of November, 2019.

The fifth workshop aims at discussing directions for future research in connexive logics. Special focus will be given on historical aspects as well as connections to conditional logics. The workshop will be collocated with a workshop on the Logic of Paradox, from the 25th to 27th, and a workshop on FDE-based modal logic on the 28th. Keynote speakers: Vincenzo Crupi, Andrea Iacona, Spencer Johnston and Marko Malink.

Component-based software development proposes sound engineering principles and techniques to cope with the complexity of present-day software systems. However, many challenging conceptual and technological issues remain in component-based software development theory and practice. Furthermore, the advent of service-oriented and cloud computing, cyber-physical systems, and the Internet of Things has brought to the fore new dimensions, such as quality of service and robustness to withstand faults, which require revisiting established concepts and developing new ones.

FACS 2019 is concerned with how formal methods can be applied to component-based software and system development. Formal methods have provided foundations for component-based software through research on mathematical models for components, composition and adaptation, and rigorous approaches to verification, deployment, testing, and certification.

Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful technique in some classical data integration tasks dealing with the semantic heterogeneity problem. It takes ontologies as input and determines as output an alignment, that is, a set of correspondences between the semantically related entities of those ontologies. These correspondences can be used for various tasks, such as ontology merging, data interlinking, query answering or process mapping.

The workshop has three goals: 1. To bring together leaders from academia, industry and user institutions to assess how academic advances are addressing real-world requirements. 2. To conduct an extensive and rigorous evaluation of ontology matching and instance matching (link discovery) approaches through the OAEI 2019 campaign. 3. To examine new uses, similarities and differences from database schema matching, which has received decades of attention but is just beginning to transition to mainstream tools.

Software systems are becoming more intelligent in the kind of functionality they offer users. At the same time, systems are becoming more decentralized, with components that represent autonomous entities who must communicate among themselves to achieve their goals. Examples of such systems range from healthcare and emergency relief and disaster management to e-business and smarts grids. A multiagent worldview is crucial to properly conceptualizing, building, and governing such systems. It offers abstractions such as intelligent agent, protocol, norm, organization, trust, incentive, and so on, and is rooted in solid computational and software engineering foundations. As a large but still growing research field of Computer Science, multiagent systems today remain a unique enabler of interdisciplinary research.

Today more than ever computers have taken center stage in our lives: science, economy, politics, art, there is no single human endeavour that has been left unaffected by Information Technologies. People connected to the Internet can enjoy an unprecedented amount of information and computing power at their disposal, but more and more negative side effects of a widespread use of computers are brought to our attention: automation bias, echo chambers, shortened attention spans, job displacement, election hacking are just a few examples. The need to conduct a systematic and well-informed discussion in a context ranging from theoretical and mathematical problems to labour and resource exploitation issues is evident.

HaPoC's appeal to historical and philosophical reflection aims at addressing this shortcoming. We aim to bring together researchers exploring the various aspects of computation: historians, philosophers, computer scientists, sociologists, anthropologists, designers, manufacturers, practitioners, artists, logicians, mathematicians, each with their own experience and expertise, all part of a society impacted by computation, and all necessary to the creation of a better discourse.

The Novembertagung on the History and Philosophy of Mathematics is an annual international conference aimed at PhD and postdoctoral students (young scholars) in the history and philosophy of mathematics.

Mathematical knowledge is commonly thought of as being essentially universal: its truths are eternal and incontrovertible, its propositions understandable and agreeable by all, independent of linguistic, cultural, ethnic or religious backgrounds. However, global knowledge, as mathematics seems to be, is always produced locally. As such, it hinges upon collectively shared ways of practicing, writing, and communicating mathematics. This year's Novembertagung invites participants to reflect on the theme 'Mathematical Cultures, Values, & Norms'. The invited speakers are June Barrow-Green (Open University) and Roy Wagner (ETH Zurich).
