We give some semantic results for an epistemic logic incorporating dynamic operators to describe information changing events. Such events include epistemic changes, where agents become more informed about the non-changing state of the world, and ontic changes, wherein the world changes. The events are executed in information states that are modeled as pointed Kripke models. Our contribution con...

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

Today’s environment and business is constantly changing on a rapid pace. Models have to be adapted in order to fit the changing situations. In contrast, the complexity of enterprise models is a huge problem wrt the management of such complex models. High-performance computing technologies offer a great opportunity to leverage increased computational power to cope with that complexity. In this p...

In this paper we describe problems occurring while modeling the dynamics of terminology context in diachronic corpora and how to solve them. The foundation for this work is context volatility, a measurement for contextual change [4], that we use as our main measuring unit. The computation of context volatility for a word relies on the significance-values of its co-occurrent terms and the corres...

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...

Communication between services requires a common vocabulary to allow reliable exchange of information. However services are evolving independently and their ontologies evolve too. The existing distributed ontology evolution approaches are not scaled to dynamic environments like Semantic Web service architecture. As the distributed system grows in size, the complexity of ontology change manageme...

Linguists have identified a number of types of recurrent semantic change, and have proposed a number of explanations, usually based on specific lexical items. This paper takes a different approach, by using a distributional semantic model to identify and quantify semantic change across an entire lexicon in a completely bottom-up fashion, and by examining which distributional properties of words...

adopting a discourse-pragmatic approach, this study examines the synchronic multifunctionality of the discourse marker hâlâ from the perspective of (inter)subjectification. the findings obtained from the synchronic corpus of colloquial persian indicates that hâlâ has proceeded along the (inter)subjectification cline identified by traugott and dasher (2002), der (2010), and degand and vandenberg...
