On the concept of relevance in legal information retrieval

The concept of 'relevance' is crucial to legal information retrieval, but because of its intuitive understanding it goes undefined too easily and unexplored too often. We discuss a conceptual framework on relevance within legal information retrieval, based on a typology of relevance dimensions used within general information retrieval science, but tailored to the specific features of legal information. This framework can be used for the development and improvement of legal information retrieval systems

Hybrid Refining Approach of PrOnto Ontology

This paper presents a refinement of PrOnto ontology using a validation test based on legal experts’ annotation of privacy policies combined with an Open Knowledge Extraction (OKE) algorithm. To ensure robustness of the results while preserving an interdisciplinary approach, the integration of legal and technical knowledge has been carried out as follows. The set of privacy policies was first analysed by the legal experts to discover legal concepts and map the text into PrOnto. The mapping was then provided to computer scientists to perform the OKE analysis. Results were validated by the legal experts, who provided feedbacks and refinements (i.e. new classes and modules) of the ontology according to MeLOn methodology. Three iterations were performed on a set of (development) policies, and a final test using a new set of privacy policies. The results are 75,43% of detection of concepts in the policy texts and an increase of roughly 33% in the accuracy gain on the test set, using the new refined version of PrOnto enriched with SKOS-XL lexicon terms and definitions

Gastroenterology and Hepatology Experts\u27 Views about the Current Information Retrieval Systems and Determining the Characteristics of the Optimal System from Their Point of View

Objective: The ideal goal of any information system is to supply and deliver the information that users need. The aim of this study is to determine gastroenterology and hepatology experts\u27 views about the current information retrieval systems and determining the characteristics of the optimal system from their point of view. Methods: This is qualitative research that has been done phenomenologically. The study population 14 gastroenterology and hepatology experts. The data collection tool was a free interview in a non-structured way. Colaizzi\u27s descriptive phenomenological method was used to collect data. Results: The problems were classified into 3 categories, 15 general themes, and 31 sub-themes. The optimal information retrieval systems were classified into 4 categories, 12 general themes, and 41 sub-themes. Conclusions: The success of information retrieval systems, especially in the field of medical sciences, depends on considering various dimensions that not paying attention to them can lead to dissatisfaction of end-users of the system and ultimately the failure of the retrieval system. Therefore, it is suggested that information retrieval system design be done by developers under the characteristics of the optimal information retrieval system by gastroenterology and hepatology expert
