Concept Hierarchy Extraction from Legal Literature

Sabine Wehnert, David Broneske, Stefan Langer, Gunter Saake
2018 International Conference on Information and Knowledge Management  
Since different authors have their own notion of hierarchy given by the table of con-tents, we propose a heterogeneous lightweight ontology allowing for the coexistence of similar, yet diverse concept  ...  This approach is novel, since state-of-the-art ontologies are conventionally modeled under full integration and in a top-down manner, often not accounting for perspectives in knowledge representation.  ...  The work is supported by Legal Horizon AG, Grant No.:1704/00082  ...

Towards a knowledge graph for open healthcare data

2020 International Journal of Advanced Trends in Computer Science and Engineering  
In this, work we propose to construct the KG4OGD, a knowledge graph that drives the transformation of open government raw data to valuable knowledge.  ...  We implemented our model for the public healthcare domain as a high interest has arisen toward this domain due to the international pandemic context.  ...  context, and the legal context.  ...

Domain Modeling for the Semantic Web: Assessing the Pragmatics of Ontologies

Melinda McDaniel, Veda C. Storey
2017 International Conference on Conceptual Modeling  
However, there is a lack of understanding of ontology quality, specifically as it relates to selecting or creating an ontology for a Semantic Web application.  ...  This research analyzes the pragmatics of domain ontologies with respect to consistency, coverage, and usability to derive a set of evaluation metrics, which are represented in a framework.  ...  Figure 4 , shows a comment from the Wyner et al.'s Legal Case Ontology [23] clarifying the meaning of the term "Issue" in the intended context of the ontology. Fig. 4.  ...

Legal Concepts and Multilingual Contexts in Digital Information

Daniela Tiscornia, Maria Teresa Sagri
2012 Beijing Law Review  
Norms are conceived as the interpreted meaning of linguistic contexts (partitions in a legal text, fragments of judicial decisions, etc).  ...  As a consequence, legal interpretation and legal conceptualization are strongly influenced by cultural, social and political factors and changes in meaning of legal concepts occur within a synchronic localization  ...  ontology depend primarily on the existing contexts.  ...

PARCo: A Knowledge-Based Agent for Context-Sensitive Reasoning and Decision-Making Regarding Privacy

Andrei Popescu, Pinar Yolum
2019 Belgium-Netherlands Conference on Artificial Intelligence  
In particular, due to its scale and heterogeneity, the IoT environment in particular, has been addressed by a limited number of efficient methods.  ...  In other words, privacy is maintained when information exchange respects the appropriateness and distribution norms related to a certain context.  ...  By using its internal representation of contexts, specified in terms of an ontology of concepts, PARCo is able to infer Alice's active contexts.  ...

Legal Knowledge Extraction for Knowledge Graph Based Question-Answering [chapter]

Francesco Sovrano, Monica Palmirani, Fabio Vitali
2020 Frontiers in Artificial Intelligence and Applications  
A Knowledge Graph (KG) is built using OKE and Natural Language Processing (NLP) methods jointly with the main ontology design patterns defined for the legal domain (e.g., event, time, role, agent, right  ...  Using critical questions, underlined by legal experts in the domain, we have built a question answering tool capable to support the information retrieval and to answer to these queries.  ...  Conclusions This paper presents a hybrid and innovative approach to model legal knowledge extracted from heterogeneous legal sources, using ontology design patterns as skeleton for mapping the information  ...

The meaningful e-marketplace

Jingzhi Guo, Guangyi Xiao
2010 2010 2nd IEEE International Conference on Information Management and Engineering  
In future, a successful realization of MEMP in design will drastically change our existing e-trade modes, lift the quality of e-business, and lead to a more efficient emarketplace brought by higher accuracy  ...  Partial understanding of any received e-trade information is forbidden since it hides unfavorable legal consequences. MEMP is a new concept.  ...  In practice, there are types of single and multiple upper ontologies in debate [21] . No matter which type, upper ontology is shared between heterogeneous domain ontologies in a more generic way.  ...

Using Mapping Languages for Building Legal Knowledge Graphs from XML Files [article]

Ademar Crotti Junior and Fabrizio Orlandi and Declan O'Sullivan and Christian Dirschl and Quentin Reul
2019 arXiv   pre-print
In this paper, we present a semantic model for representing legal documents together with an industrial use case.  ...  The information contained in legal information systems are often accessed through simple keyword interfaces and presented as a simple list of hits.  ...  Ontologies, in this context, are seen as formal, explicit specifications of conceptualizations [9] .  ...

Semantics-Enabled Policies for Information Sharing and Protection in the Cloud [chapter]

Yuh-Jong Hu, Win-Nan Wu, Jiun-Jan Yang
2011 Lecture Notes in Computer Science  
The emerging challenges of legalizing semanticsenabled policies for laws in the cloud include mitigating the gap between semantics-enabled policy and laws to avoid any ambiguity in the policy representation  ...  The semantics-enabled policies of information sharing and protection are represented as a combination of ontologies and rules to capture the concept of security and privacy laws.  ...  Using ontology as a formal representation of a policy and a meta-policy for solving the policy semantic heterogeneity and conflict are very promising.  ...

Semantic Inference on Heterogeneous E-Marketplace Activities

Jingzhi Guo, Lida Xu, Zhiguo Gong, Chin-Pang Che, Sohail S. Chaudhry
2012 IEEE transactions on systems, man and cybernetics. Part A. Systems and humans  
The solution, called the RuleXPM approach, enables one to semantically infer a next e-marketplace activity across multiple contexts/domains.  ...  An electronic marketplace (e-marketplace) is a common business information space populated with many entities of different system types. Each of them has its own context of how to process activities.  ...  Any misinterpretation will lead to legal consequences because the BDs contained in these activities are legally binding to legal responsibilities.  ...

MedMatch – Towards Domain Specific Semantic Matching [chapter]

Jetendr Shamdasani, Peter Bloodsworth, Kamran Munir, Hanene Boussi Rahmouni, Richard McClatchey
2011 Lecture Notes in Computer Science  
Ontologies are increasingly being used to address the problems of heterogeneous data sources. This has in turn often led to the challenge of heterogeneity between ontologies themselves.  ...  Semantic Matching has been seen as a potential solution to resolving ambiguities between ontologies .  ...  Creating an ontology that covers the entire legal domain is a very challenging task. Some legal ontologies appear to be well developed.  ...
