Properties of ABA+ for Non-Monotonic Reasoning
Full text linkWe investigate properties of ABA+, a formalism that extends the well studied
structured argumentation formalism Assumption-Based Argumentation (ABA) with a
preference handling mechanism. In particular, we establish desirable properties
that ABA+ semantics exhibit. These pave way to the satisfaction by ABA+ of some
(arguably) desirable principles of preference handling in argumentation and
nonmonotonic reasoning, as well as non-monotonic inference properties of ABA+
under various semantics.Comment: This is a revised version of the paper presented at the worksho
On the Optimized Utilization of Smart Contracts in DLTs from the Perspective of Legal Representation and Legal Reasoning
Get PDFSmart contracts are computer programs stored in blockchain which
open a wide range of applications but also raise some important issues. When we
convert traditional legal contracts written in natural language into smart contracts
written in lines of code, problems will arise. Translation errors will exist in the
process of conversion since the law in natural language is ambiguous and imprecise,
full of conflicts, and the emergence of new evidence may influence the processing
of reasoning. This research project has three purposes: the first aims at
the resolution of these problems from logic and technical perspective to develop
the accuracy and human-readability of smart contracts, by exploring a more novel
and advanced logic-based language to represent legal contracts, and analyzing an
extended argumentation framework with rich expressiveness; the second purpose
is to investigate various existing technologies like Akoma Ntoso and Legal-
RuleML, making the legal knowledge and reasoning machine-readable and be
linked with the real world; third, to investigate the implementation of a mature
multi-agent system incorporating the software agents with sensing, inferring,
learning, decision-making and social abilities that can be fitted onto DLTs
