Although multiple bibliometric studies have been conducted to analyze publications on various topics within tourism, little attention has dedicated systematically analyzing scholarly production the topic of tourism sustainability. Consequently, this paper aims conduct a comprehensive and systematic review The collected data include 6326 retrieved from Scopus database. technique consists two maj...

Natural human interaction is highly dynamic and responsive: interlocutors produce utterances incrementally, smoothly switch speaking turns with virtually no delay, make use of on-the-fly adaptation and (self) interruptions, execute movement in tight synchrony, etc. We present the conglomeration of our research efforts in enabling the realization of such fluent interactions for Embodied Conversa...

An additive fluent is a fluent with numerical values such that the effect of several concurrently executed actions on it can be computed by adding the effects of the individual actions. We propose a method for describing effects of actions on additive fluents in the declarative language C+. An implementation of this language, called the Causal Calculator, can be used for the automation of examp...

BACKGROUND People who stutter produce speech that is characterized by intermittent, involuntary part-word repetitions and prolongations. In addition to these signature acoustic manifestations, those who stutter often display repetitive and fixated behaviours outside the speech producing mechanism (e.g. in the head, arm, fingers, nares, etc.). Previous research has examined the attitudes and per...

Many real-world planning problems are best modeled as infinite search space problems, using numeric fluents. Unfortunately, most planners and planning heuristics do not directly support such fluents. We propose a search space abstraction technique that compiles a planning problem with numeric fluents into a finite state propositional planning problem. To account for the loss of precision result...

FLUX is a declarative, CLP-based programming method for the design of agents that reason logically about their actions and sensor information in the presence of incomplete knowledge. The mathematical foundations of FLUX are given by the fluent calculus, which provides a solution to the fundamental frame problem in classical logic. We show how FLUX can be readily used as a platform for specifyin...

Aiming at the former formalized methods of robot planning should give the environment state, can not obtain the new knowledge of the environment. In order to improve the reason ability for obtaining new knowledge of the environment state, the actions in the process of planning such as external action and sensing action are formalized. A formalized reasoning method—CPNI (Colored Petri Net for Pl...

Planning is a natural domain of application for frameworks of reasoning about actions and change. In this paper we study how one such framework, the Language E , can form the basis for planning under (possibly) incomplete information. We define two types of plans: weak and safe plans, and propose a planner, called the E-Planner, which is often able to extend an initial weak plan into a safe pla...
