It is difficult to find resources on the Semantic Web today, in particular if one wants to search for resources based on natural language keywords and across multiple datasets. In this paper, we present LOTUS: Linked Open Text UnleaShed, a full-text lookup index over a huge Linked Open Data collection. We detail LOTUS’ approach, its implementation, its coverage, and demonstrate the ease with wh...

Use cases constitute a popular technique to problem analysis, partly due to their focus on thinking in terms of the user needs. However this is not a guarantee for discovering all the subproblems that compose the structure of a given software problem. Moreover, a rigorous application of the technique requires a previous consensus about the meaning of I. Jacobson’s statement “a use case must giv...

New functional representation for the strongly interacting systems is proposed which contains a new type of the coherent state. As a result the new algebraic structureso called ”tower of algebras” appears which gives the tower (or hierarchy) of models. 1 Functional approach. Consider Hubbard model (lattice version of Thirring model) [1]: H = −t ∑ ,σ αrσ + αr′σ + U ∑ r nr,↑nr,↓ = Hband = (1)

Econometric Causality This paper presents the econometric approach to causal modeling. It is motivated by policy problems. New causal parameters are defined and identified to address specific policy problems. Economists embrace a scientific approach to causality and model the preferences and choices of agents to infer subjective (agent) evaluations as well as objective outcomes. Anticipated and...

The paper describes a new evaluation measure for speech recognition in spoken language dialogue systems. The measure is based on the usefulness of the recognition for the system, and the usefulness is measured at the level of meaning representation. It is argued that the new measure is more useful than word error rate, and is more accurate than simpler functional measures.

Oxytocin is an evolutionarily highly preserved neuropeptide that contributes to the regulation of social interactions including the processing of facial stimuli. We hypothesized that its improving effect on social approach behavior depends on perceived sexual features and, consequently, on sexual orientation. In 19 homosexual and 18 heterosexual healthy young men, we investigated the acute effe...

A mathematical driver model is given in the spacial equation form, which takes into account the previewed information of the path. Optimal control method is considered for the ideal no time-delay case and Lyapunov-Krasovskii functional approach is applied to deal with drivers’ reaction time-delay. For both cases, exponential stability is guaranteed for the closedloop system.

This paper studies a principal–agent relation in which the principal’s private information about the agent’s effort choice is more accurate than a noisy public performance measure. For some contingencies the optimal contract has to specify ex post inefficiencies in the form of inefficient termination (firing the agent) or third–party payments (money burning). We show that money burning is the l...

In this paper we continue the study of the geometrical features of a functional approach to classical mechanics proposed some time ago. In particular we try to shed some light on a N=2 " universal " supersymmetry which seems to have an interesting interplay with the concept of ergodicity of the system. To study the geometry better we make this susy local and clarify pedagogically several issues...
