Ontology Learning Process as a Bottom-up Strategy for Building Domain-specific Ontology from Legal Texts

Mirna El Ghosh, Hala Naja, Habib Abdulrab, Mohamad Khalil
2017 Proceedings of the 9th International Conference on Agents and Artificial Intelligence  
The knowledge structures that interest us are legal domain-specific ontologies. We will use these ontologies to build legal domain ontology for a Lebanese legal knowledge based system.  ...  Ontologies can be learnt from various sources, such as databases, structured and unstructured documents. Here, the focus is on the acquisition of ontologies from unstructured text, provided as input.  ...  ACKNOWLEDGEMENTS This project has been funded with support from the European Union with the European Regional Development Fund (ERDF), the National Support from the National Council for Scientific Research  ...

Introduction: Special Issue on Racial Capitalism and Law

Carmen Gonzalez, Athena Mutua
2022 Journal of Law and Political Economy  
The first type is social relations of extraction, in which it is acceptable for persons to extract labor from others and for powerful people to extract the raw materials of others over their objection.  ...  The concept of racial capitalism has spawned a vast interdisciplinary literature, reflecting multiple theoretical perspectives on the various ways that race and class (along with gender, disability, and  ...  We believe that the concept of racial capitalism is a promising area for legal scholarship, and we hope that this special issue will inspire more legal scholars to engage with the interdisciplinary literature  ...

Mining Disease-Symptom Relation from Massive Biomedical Literature and Its Application in Severe Disease Diagnosis

Eryu Xia, Wen Sun, Jing Mei, Enliang Xu, Ke Wang, Yong Qin
2018 AMIA Annual Symposium Proceedings  
Here we present a study on mining disease-symptom relation from massive biomedical literature and constructing biomedical knowledge graph from the relation.  ...  From 15,970,134 MEDLINE/PubMed citation records, occurrences of 8,514 disease concepts from the Human Disease Ontology and 842 symptom concepts from the Symptom Ontology and their relation were analyzed  ...  Different from EMR data, which have legal and ethical restrictions to data access, most biomedical literature reports can be openly accessed.  ...

Towards a Middle-out Approach for Building Legal Domain Reference Ontology

M. El Ghosh, H. Naja, H. Abdulrab, M. Khalil
2016 International Journal of Knowledge Engineering  
(top-down strategy) and Ontology Learning Process from textual resources (bottom-up strategy).  ...  This article presents a middle-out approach to build legal domain reference ontology for a Legal Knowledge Based System (LKBS).  ...  In other words, the concepts of the penal domain can be extracted from the textual resources, such as Infraction, and can be aligned with the concepts specialized from the top modules (upper and core).  ...

A Review on Ontology Learning Approaches of Creating a Topic Map of Cybercrime Research

Kijung Lee
2019 INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY  
Researchers in such a field, therefore, can benefit from understanding the related domains of one's own research.  ...  Especially, the methods we discuss here are text mining techniques for extracting ontology components, denoted as ontology learning.  ...  Heuristic 8 and 9 concern table tags; topics extracted from a same row in a table are related while topics extracted from a same column are in topic -sub-topic hierarchy.  ...

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

Francesco Sovrano, Monica Palmirani, Fabio Vitali
2020 Frontiers in Artificial Intelligence and Applications  
This paper presents the Open Knowledge Extraction (OKE) tools combined with natural language analysis of the sentence in order to enrich the semantic of the legal knowledge extracted from legal text.  ...  The system should help the legal expert to retrieve the relevant legal information connected with topics, concepts, entities, normative references in order to integrate his/her searching activities.  ...  Extracting: extract C from Q, using the same procedure adopted for extracting concepts during the KG extraction in section 3.1. 2.  ...

Events in the legal domain: first impressions

María Navas-Loro, Cristiana Santos
2018 Zenodo  
Aspects such as the concept of relevance are discussed, along with choices for evaluation. Possible strategies for extraction of legal events are described.  ...  In this paper, we analyze current approaches to event representation and extraction in the legal domain, and we review generic approaches as well.  ...  Acknowledgments This work was supported by a Predoctoral grant from the I+D+i program of the Universidad Politécnica de Madrid.  ...

A Theoretical Proposition for Spatial Data Infrastructure On-Going Improvement

Lopang Maphale, Julian L. Smit
2020 ISPRS International Journal of Geo-Information  
To reap from this technological boom, the geospatial information community has come up with a pervasive and network enabling concept called spatial data infrastructure (SDI).  ...  Over the years, several countries have embraced the SDI concept to shape policy, build and share geospatial information resources.  ...  In the case of the reviewed literature, Refs. [3, 4] are specifically acknowledged because data summarized from them have afforded support and credibility to the SDIOGI proposition as a temporal cyclic  ...

Legal NERC with ontologies, Wikipedia and curriculum learning

Cristian Cardellino, Milagro Teruel, Laura Alonso Alemany, Serena Villata
2017 Proceedings of the 15th Conference of the European Chapter of the Association for Computational Linguistics: Volume 2, Short Papers  
However, we find that in this particular setting, the method works best by learning from most specific to most general concepts, not the other way round.  ...  In this paper, we present a Wikipediabased approach to develop resources for the legal domain.  ...  Moreover, only very few annotated legal corpora exist where entities can be gathered from. All this constitutes an important barrier for Information Extraction from legal text.  ...
