Natural language generation (NLG) is an important component in spoken dialogue systems. This paper presents a model called Encoder-Aggregator-Decoder which is an extension of an Recurrent Neural Network based Encoder-Decoder architecture. The proposed Semantic Aggregator consists of two components: an Aligner and a Refiner. The Aligner is a conventional attention calculated over the encoded inp...

Due to the limited predictability and associated uncertainty of renewable energy resources, renewable-based electricity systems are confronted with instability problems. In such power systems, implementation of Demand Response (DR) programs not only can improve the system stability but also enhances market efficiency and system reliability. By implementing cloud-based engineering systems the ut...

Increased variable renewable energy sources requires more flexibility that could be provided by distributed energy sources located at small end-users. Aggregators could act as intermediary entities to exploit the flexibility potential of small end-users and create value for DSOs by offering congestion management services. An optimization model based on Linear Programming is developed and used t...

This paper studies an aggregate demand prediction problem relevant in smart grids. In our model, an aggregator agent is responsible for eliciting the demand forecasts of a number of self-interested home agents and purchasing electricity for them. Forecasts are given in form of probability distributions, and generating them incurs costs proportional to their precision. The paper presents a novel...

The telecommunications-centric business model of mobile operators is under attack due to technological convergence in the communication and content industries. This has resulted in a plethora of academic contributions on the design of new business models and service platform architectures. However, a discussion of the challenges that operators are facing in adopting these models is lacking. We ...

This paper presents a fuzzy extension of TOPSIS (technique for order performance by similarity to ideal solution) with a new quantifier guided distance metric and majority opinion aggregator for multi-criteria decision making in a group decision environment. The proposed distance metric is based on OWA aggregators and provides an opportunity to use linguistic quantifiers to have linguistic defi...

Trust in distributed systems is an inherently difficult problem, as nodes need to decide which other nodes to trust without a central, verifiably trusted authority. This paper evaluates the notion of a distributed sub-network of trust aggregators based on the NICE trust cookie and trust chain system. The aggregators simply keep the trust cookies, which prove delivery of a resource during a tran...

Interoperable Grid monitoring has been a hot topic since many years (Wolski et al 1999, Michael and Philip 2002). Standardization efforts have been made by the Open Grid Forum with respect to monitoring architecture (Zanikolas et al 2005) and data schema. Grid middleware efforts towards interoperability include GRIP, which resulted in an interoperability layer between UNICORE and GT2, OSG, LCG ...
