The architecture, interface, and functionality of the Windows Application Programming Interface (API) make it difficult to master and use effectively, and contribute negatively to the safety, robustness, and portability of the applications developed under it. The API is structured around a large and constantly evolving set of functions and is based on a problematic shared library implementation...

This work presents a Java interface to a native BSPlib library for implementing parallel algorithms in a structured way (as described by the BSP model), using the Java programming language. To compare the created library to existing parallel programming solutions, a typical physics simulation application is created. It employs the parallel conjugate gradient method for solving systems of linear...

The Open Mathematical Engine Interface (OMEI) aims to establish a uniform application programming interface (API) for heterogeneous mathematical computation engines. A common API such as OMEI can make mathematical engines easily accessible by front-ends, tools, and servers. It also enables the development of individual applications that can serve or utilize different engines. The motivation, ap...

One of the nice things about purely functional languages is that functions often satisfy simple properties, and enjoy simple algebraic relationships. Indeed, if the functions of an API satisfy elegant laws, that in itself is a sign of a good design— the laws not only indicate conceptual simplicity, but are useful in practice for simplifying programs that use the API, by equational reasoning or ...

We present Sentilyzer, a web-based tool that can be used to analyze and visualize the sentiment of German user comments on Facebook pages. The tool collects comments via the Facebook API and uses the TreeTagger to perform basic lemmatization. The lemmatized data is then analyzed with regard to sentiment by using the Berlin Affective Word List – Reloaded (BAWL-R), a lexicon that contains emotion...

This document describes the Odin framework, which is a domain-independent platform for developing rule-based event extraction models. Odin aims to be powerful (the rule language allows the modeling of complex syntactic structures) and robust (to recover from syntactic parsing errors, syntactic patterns can be freely mixed with surface, token-based patterns), while remaining simple (some domain ...

One challenge of building future grid systems is to provide suitable application programming interfaces and environments. In this chapter, we identify functional and non-functional properties for such environments. We then review three existing systems that have been co-developed by the authors with respect to the identified properties: ProActive, Ibis, and GAT. Apparently, no currently existin...
