Synthesis of Petri nets from behavioral descriptions has important applications in the design of systems in different application areas. In this paper we present a survey on the technique of region based synthesis of Petri nets from languages. Each word in a given language specifies one run of the searched Petri net, i.e. represents one observable scenario of the system. We concentrate on recen...

The ambiguous and highly subjective meanings assigned to the word “interaction” makes it difficult for the researchers and practitioners, who work in the area of virtual environments and applications, to communicate and join their research efforts. The aim of this work is to provide more understanding on the interaction occurring inside Networked Virtual Environments (Net-VE) by analysing the c...

BACKGROUND Word retrieval during verbal fluency tasks invokes both automatic and controlled cognitive processes. A distinction has been made between the generation of words clusters and switches between such clusters on verbal fluency tasks. Clusters, defined by the reporting of contiguous words that constitute semantic or phonemic subcategories, are thought to reflect relatively automatic proc...

With the popularity of online shopping it is increasingly becoming important for manufacturers and service providers to ask customers to review their product and associated service. Typically the number of customer reviews that a product receives grows rapidly and can be in hundreds or even thousands. This makes it difficult for a potential customer to decide whether to buy the product or not. ...

In this paper, we present an online algorithm for state estimation of timed choice-free Petri nets. We assume that the net structure and initial marking are known, and that the set of transitions is divided in observable and unobservable one. Given an observed word and assuming that the time durations associated to the unobservable transitions are unknown, our problem is to estimate the possibl...

These days, the language is making hindrances in the advantages of Information Technology revolution in India. So, there is the need of the adequate measures to perform natural language processing (NLP) through computer processing so that computer based system can be interacted by users through natural language like Hindi. This paper presents a new Word Sense Disambiguation method associated wi...

In this paper we discuss the problem of estimating the marking of a Place/Transition net based on event observation. We assume that the net structure is known while the initial marking is totally or partially unknown. We give algorithms to compute a marking estimate that is a lower bound of the actual marking. The special structure of Petri nets allows us to use a simple linear algebraic formal...

The Inter Lingual Index ILI in the EuroWordNet architecture is an initially unstructured fund of con cepts which functions as the link between the vari ous language wordnets The ILI concepts originate fromWordNet and have been restructured on the basis of aspects of the internal structure of Word Net links between WordNet and other resources and multilingual mapping between the wordnets This le...
