This open access book constitutes the thoroughly refereed post-conference proceedings of the 6th International Workshop on Graph Structures for Knowledge Representation and Reasoning, GKR 2020, held virtually in September 2020, associated with ECAI 2020, the 24th European Conference on Artificial Intelligence. The 7 revised full papers presented together with 2 invited contributions were revie…
This book is also the story of how we(the authors) as computer science researchers embarked on a journey to engage with a new research field – equity and gender in computing – about which we had only sporadic knowledge when we began. We refer here to equity and gender in computing as a research field – but in reality, this research field is a multiplicity of entangled paths, concepts, and…
This open access book provides an in-depth description of the EU project European Language Grid (ELG). Its motivation lies in the fact that Europe is a multilingual society with 24 official European Union Member State languages and dozens of additional languages including regional and minority languages. The only meaningful way to enable multilingualism and to benefit from this rich linguistic …
This open access volume explains the foundations of modern solvers for ordinary differential equations (ODEs). Formulating and solving ODEs is an essential part of mathematical modeling and computational science, and numerous solvers are available in commercial and open source software. However, no single ODE solver is the best choice for every single problem, and choosing the right solver requ…
Speaking Code begins by invoking the "Hello World" convention used by programmers when learning a new language, helping to establish the interplay of text and code that runs through the book. Interweaving the voice of critical writing from the humanities with the tradition of computing and software development, in Speaking Code Geoff Cox formulates an argument that aims to undermine the distinc…
Wikipedia, the online encyclopedia, is built by a community - a community of Wikipedians who are expected to "assume good faith" when interacting with one another. In Good Faith Collaboration, Joseph Reagle examines this unique collaborative culture;Wikipedia, says Reagle, is not the first effort to create a freely shared, universal encyclopedia; its early twentieth-century ancestors include Pa…
Genetic programming is a domain-independent method for automatic programming that evolves computer programs that solve, or approximately solve, problems. Starting with a primordial ooze of thousands of randomly created computer programs composed of functions and terminals appropriate to a problem, a population of programs is progressively evolved over many generations using the Darwinian princi…
The history of computing could be told as the story of hardware and software, or the story of the Internet, or the story of "smart" hand-held devices, with subplots involving IBM, Microsoft, Apple, Facebook and Twitter. In this account of the invention and development of digital technology, the author, a computer historian offers a broader and more useful perspective. He identifies four major t…
"Spreadsheets are used daily by millions of people for tasks that range from organizing a list of addresses to carrying out complex economic simulations. Spreadsheet programs are easy to learn and convenient to use because they have a clear visual model and a simple efficient underlying computational model. Yet although the basic spreadsheet model could be extended, improved, or otherwise exper…
Much of the business transacted on the Web today takes place through information exchanges made possible by using documents as interfaces. For example, what seems to be a simple purchase from an online bookstore actually involves at least three different business collaborations -- between the customer and the online catalog to select a book; between the bookstore and a credit card authorization…
