    firstCS—New Aspects on Combining Constraint Programming with Object-Orientation in Java
    (KI - Künstliche Intelligenz: Vol. 26, No. 1, 2012) Wolf, Armin
    The aim of the presented constraint programming library firstCS is the integration of the constraint programming paradigm in the object-oriented programming language Java. This open-box library provides its users with the necessary concepts to model and solve constraint satisfaction problems and even constraint optimization problems over finite integer domains. The application focus of firstCS is constraint-based scheduling and resource allocations (e.g. Sandow in INFORMATIK 2011, LNI, vol. P-192, p. 248, 2011), however, it offers all primitives to realize new constraints and according propagation algorithms as well as problem-specific tree search heuristics to find good or even best solutions. Beyond related work and an overview over the general architecture of the system and the supported constraints, this presentation focuses on new aspects of the current version of firstCS, i.e. redundancy checking and the assembling of new search strategies from existing ones using the implementation language Java. The presentation is completed by code fragments showing interesting implementation details.

    No More Battles – User-centric Approaches as Key to Successful Intranets
    (i-com: Vol. 14, No. 1, 2015) Wagner, Anne Christine
    In the short history of intranets a lot of IT-centric paradigms have been prevailing (tool choice, architectural questions, overall IT strategy). The emergence of intranet paradigms, referred to as Web2.0, as well as changed user expectations due to consumerization and high adaption of mobile devices challenge the traditionally technology-driven approach in enterprises: Today, users realize that there is more to claim and fight for. This article introduces approaches that start from the practitioner's perspective and help to align users, IT and strategic stakeholders with the purpose of forming an alliance between them and of finding the scope and design that fits all requirements.

    Search Challenges in Natural Language Generation with Complex Optimization Objectives
    (KI - Künstliche Intelligenz: Vol. 30, No. 1, 2016) Demberg, Vera; Hoffmann, Jörg; Howcroft, David M.; Klakow, Dietrich; Torralba, Álvaro
    Automatic natural language generation (NLG) is a difficult problem already when merely trying to come up with natural-sounding utterances. Ubiquituous applications, in particular companion technologies, pose the additional challenge of flexible adaptation to a user or a situation. This requires optimizing complex objectives such as information density, in combinatorial search spaces described using declarative input languages. We believe that AI search and planning is a natural match for these problems, and could substantially contribute to solving them effectively. We illustrate this using a concrete example NLG framework, give a summary of the relevant optimization objectives, and provide an initial list of research challenges.

    Twoogle: Searching Twitter With MongoDB Queries
    (BTW 2019, 2019) Wingerath, Wolfram; Gessert, Felix; Ritter, Norbert
    Modern real-time databases follow the same collection-based querying semantics as traditional database systems. Targeting interactive workloads, real-time databases do not only deliver a query’s result upon request, but also produce a continuous stream of informational updates thereafter. In theory, building interactive, reactive, or collaborative applications should thus be simple with collection-based real-time queries as they bridge the gap between traditional database queries over static collections and continuous queries over dynamic data streams. In practice, though, building real-time applications is still considered challenging, since most real-time databases today provide only poor scalability, confusing interfaces for real-time data access, and reduced query expressiveness in comparison to their pull-based counterparts. In this demo, we illustrate that scalability, query expressiveness, and simplicity can go hand-in-hand for modern real-time databases. To this end, we present the social media search app Twoogle which is built on top of Baqend’s real-time query API.
