This paper presents a formal model of legal norms modeled in OWL. It is intended for semiautomatic drafting and semantic retrieval and browsing of legislation. Most existing solutions model legal norms using formal logic, rules or ontologies. Nevertheless, they were not intended as a basis for drafting, retrieval and browsing of legislation. The pr...

This paper proposes a non-domain-specific metadata ontology as a core component in a semantic model-based document management system (DMS), a potential contender towards the enterprise information systems of the next generation. What we developed is the core semantic component of an ontology-driven DMS, providing a robust semantic base for describi...

Public access to case law is a required prerequisite for the legal certainty and the rule of law. Nevertheless, according to the law, only authorized persons can access judgments in their non-anonymized and unredacted form. This paper proposes a computer aided method for anonymization and redaction of judgments, with an aim to improve efficiency of...

During the past two decades, e-government information systems have become less paper-based and more computer-based. Those information systems usually take the form of workflow systems. Due to the large social impact of e-government systems, computer security plays a pivotal role in ensuring its efficiency and effectiveness. Access control is one of...

This paper proposes a knowledge-based legal document assembly method that uses a machine-readable representation of knowledge of legal professionals. This knowledgebase has two components - the formal knowledge of legal norms represented as a rule-base and the tacit knowledge represented by a document template. A document assembly system is develop...
Article
This paper proposes a method for knowledge-based document assembly. A document assembly system is implemented as a proof of concept with service contracts as a sample document type. In comparison to related research, the method presented in this paper uses an explicit formulation of legal norms that prescribes the content and the form of service co...
Chapter
This chapter reviews developments in the legal web ‐ from standardized machine‐readable document formats, metadata ontologies and citation schemas, through automatic extraction of data from text, to successful case studies of computer‐assisted services. The legal informatics academic community specialized web standards to the legal domain. The most...

Workflow management systems (WfMS) are used to automate and facilitate business processes of an enterprise. To simplify the administration, it is a common practice in many WfMS solutions to allocate a role to perform each activity of the process and then assign one or more users to each role. Typically, access control for WfMS is role-based with a...
Conference Paper
The recently introduced concept of a legislation network is a promising approach to addressing the challenging issues of tackling with and quantifying the complexity of the legislation. In this paper, we described the process of crawling and scraping Serbian legislation, applying natural language processing methods to detect references in legislati...
Article
Purpose The purpose of this paper is to identify the benefits of an approach in which document management systems (DMSs) are based on a formal and explicit document model, primarily in terms of facilitating domain-specific customization. Design/methodology/approach Within this paper, a generic document model is proposed. The model consists of tw...

Nowadays we have various languages, framework and tools for specification and implementation of distributed systems. Nevertheless, developing a robust distributed system still poses a challenging task. Starting from the definition that a distributed system is a system where networked components communicate via passing messages, we wanted to explore...

This paper describes an approach for enabling unified, document type independent semantic web-based reasoning over various metadata sources in a document management system. A comprehensive, yet concise non-domain-specific metadata ontology influenced by ebXML RegRep standard is proposed to serve as a semantic basis for other domain-specific metadat...

This paper introduces a conceptualization of the document management domain that is serving as a foundation for a semantically-driven document management system. The conceptualization is based on the ISO 82045 family of standards for document management and is specified in OWL. Legislative documents were used as a case study and a proof of concept...

The paper analysis the performances of different RDF stores on servers with average hardware specification. For this purpose, various tests have been performed on three RDF stores, namely Jena-Fuseki, Sesam-OWLIM and Virtuoso. Using different data sets and queries, the tests have measured CPU usage, heap memory consumption and execution time. Based...

In order to understand judicial complaints more clearly (to avoid misinterpretations and to provide additional clarification of its content), structural and semantic markup can be rather helpful. By structural and semantic markup, claims can be semantically enhanced using legal ontologies and legal knowledge interchange format argument graphs makin...
