Non-fungible tokens (NFTs) make it technically possible for digital assets to be owned and traded, introducing the concept of scarcity in realm first time. Resulting from this technical development, paper asks question, do they provide an opportunity fundraising galleries, libraries, archives museums (GLAM), by selling ownership copies their collections? Although NFTs current format were invented 2017 as a means game players trade virtual goods, reached mainstream 2021, when auction house...
Nonmonotonic rule systems are expected to play an important role in the layered development of semantic Web. Defeasible reasoning is a direction nonmonotonic that based on use rules may be defeated by other rules. It simple, but often more efficient approach than for with incomplete and inconsistent information. This paper reports implementation system defeasible The 1) syntactically compatible RuleML, 2) features strict rules, priorities, two kinds negation, 3) translation logic programming...
The imperfect nature of context in Ambient Intelligence environments and the special characteristics entities that possess share available information render contextual reasoning a very challenging task. accomplishment this task requires formal models handle involved as autonomous logic-based agents provide methods for handling distributed context. This paper proposes solution based on Multi-Context Systems paradigm which local knowledge ambient is encoded rule theories (contexts), flow...
While Large Language Models (LLMs) demonstrate impressive reasoning capabilities, understanding and validating their knowledge utilization remains challenging. Chain-of-thought (CoT) prompting partially addresses this by revealing intermediate steps, but the flow application remain implicit. We introduce IAO (Input-Action-Output) prompting, a structured template-based method that explicitly models how LLMs access apply during complex tasks. decomposes problems into sequential each clearly...
Today, privacy is a key concept. It also one which rapidly evolving with technological advances, and there no consensus on single definition for it. In fact, the concept of has been defined in many different ways, ranging from "right to be left alone" being "commodity" t hat can bought sold. same time, powerful Ambient Intelligence (AmI) systems are developed, that deploy context-aware, personalised, adaptive anticipatory services. such personal data vastly collected, stored, distributed,...
In an increasingly instrumented and inter-connected digital world, citizens generate vast amounts of data, much it personal, nearly all valuable. However, controlling who can collect it, limiting what they do with determining how best to protect remain deeply undecided issues. This position paper proposes a socio-technical solution based on collective awareness informed consent, whereby data collection protection norms are configured by the users themselves, using collaborative participatory...
We present semantics-based mechanisms that aim to promote reflection on cultural heritage by means of dates (historical events or annual commemorations), owing their connections a collection items and the visitors’ interests. argue links specific can trigger curiosity, increase retention guide visitors around venue following new appealing narratives in subsequent visits. The proposal has been evaluated pilot study Archaeological Museum Tripoli (Greece), for which team humanities experts...
