Knowledge-based recommender systems are Web-based applications that exploit deep domain knowledge for generating buying proposals that match the individual needs and requirements of an online user. As in many domains the detailed customer requirements have to be elicited in an interactive dialog

this paper we present an approach for interactive B2C eCommerce systems that support the required guided transition from a needs- to a feature-oriented interaction. The approach distinguishes between a model level and a system level (see Figure 1). On the model level, this approach suggests novel

interdependencies between the recommendation and personalization knowledge. In this paper, we present ADVISOR SUITE, an integrated, domain-independent environment for the development of highly-interactive, personalized recommender applications. The main pillars of the presented system are a) an integrated, model

Ultracold atoms in optical lattices provide a highly control-lable environment for the clean experimental realization of various model Hamiltonians from condensed matter and statistical physics. For example, the two-component Bose-Hubbard model, which re-duces to an anisotropic spin-1/2 Heisenberg model in a certain limit and thus allows for the study of quantum magnetism, can be im-plemented by using bosons with two different internal states that couple differently to an optical lattice potential. In this thesis, I present our first experiments with two-component hyperfine-state mixtures of ultracold 87Rb atoms in a state-dependent optical lat-tice, both in the strongly correlated regime and in the context of nonlinear atom optics. For the production of 87Rb Bose-Einstein condensates we have developed a moving-coil transporter apparatus featuring a mag-netic TOP trap which serves as a “phase-space funnel ” to load a

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable

Building on prior theory and research, this research has developed empirically derived, practical findings and recommendations to support the development of appropriate interoperable systems.
