Onto-Med Research Group

Overview
Description:

The Onto-Med Research Group conducts basic research in formal ontology, designs formal tools for constructing and managing ontologies and develops top level ontologies as well as domain and core ontologies for medicine, bio-medicine and biology, but also for other fields. The Onto-Med group uses an interdisciplinary approach, combining methods from logic, computer science, philosophy and cognitive linguistics. The Onto-Med group considers Formal Ontology as an evolving science which is concerned with systematically developing axiomatic theories that describe forms, structures, and modes of being at different levels of abstraction and granularity. The roots of formal ontology can be traced back to the philosophical investigations of Aristotle and Plato. Their work was creatively enriched during the early Middle Ages by Islamic philosophers, including Avicenna, renowned as one of the history's greatest thinkers and medical scholars. The Onto-Med Research Group was founded in 2002 and is a result of a collaboration between the Institute for Medical Informatics, Statistics, and Epidemiology (IMISE), University of Leipzig, and the Department of Formal Concepts at the Institute for Informatics (IfI), University of Leipzig.

Simple Ontology Loader in Drupal (SOLID)
Onto-Med Research Group

This is a Drupal 8 Module to import nodes and taxonomies into Drupal, using the available API. The module is capable of importing a JSON or OWL file. Idea is to enable users to upload a file containing all information about nodes and their relations. The module will then import all contained information with the Drupal 8 API. Nodes can be specified as "articles" or any other custom node type. The node classification becomes one (or multiple) hierachical vocabulary. Supported import formats are

Light-Weighted Automatic Import of Standardized Ontologies into the Content Management System Drupal.
Onto-Med Research Group

Abstract (Expand)

The amount of ontologies, which are utilizable for widespread domains, is growing steadily. BioPortal alone, embraces over 500 published ontologies with nearly 8 million classes. In contrast, the vast … informative content of these ontologies is only directly intelligible by experts. To overcome this deficiency it could be possible to represent ontologies as web portals, which does not require knowledge about ontologies and their semantics, but still carries as much information as possible to the end-user. Furthermore, the conception of a complex web portal is a sophisticated process. Many entities must be analyzed and linked to existing terminologies. Ontologies are a decent solution for gathering and storing this complex data and dependencies. Hence, automated imports of ontologies into web portals could support both mentioned scenarios. The Content Management System (CMS) Drupal 8 is one of many solutions to develop web presentations with less required knowledge about programming languages and it is suitable to represent ontological entities. We developed the Drupal Upper Ontology (DUO), which models concepts of Drupal's architecture, such as nodes, vocabularies and links. DUO can be imported into ontologies to map their entities to Drupal's concepts. Because of Drupal's lack of import capabilities, we implemented the Simple Ontology Loader in Drupal (SOLID), a Drupal 8 module, which allows Drupal administrators to import ontologies based on DUO. Our module generates content in Drupal from existing ontologies and makes it accessible by the general public. Moreover Drupal offers a tagging system which may be amplified with multiple standardized and established terminologies by importing them with SOLID. Our Drupal module shows that ontologies can be used to model content of a CMS and vice versa CMS are suitable to represent ontologies in a user-friendly way. Ontological entities are presented to the user as discrete pages with all appropriate properties, links and tags.

Ontology-Based Modelling of Web Content: Example Leipzig Health Atlas
Onto-Med Research Group

Abstract (Expand)

The realisation of a complex web portal, including the modelling of content, is a challenging process. The contents describe different interconnected entities that form a complex structure. The entities … and their relations have to be systematically analysed, and the content has to be specified and integrated into a content management system (CMS). Ontologies provide a suitable solution for modelling and specifying complex entities and their relations. However, the functionality for automated import of ontologies is not available in current content management systems. In order to describe the content of a web portal, we developed an ontology. Based on this ontology, we implemented a pipeline that allows the specification of the portal’s content and its import into the CMS Drupal. Our method is generic. It enables the development of web portals with the focus on a suitable representation of structured knowledge (entities, their properties and relations). Furthermore, it makes it possible to represent existing ontologies in such a way that their content can be understood by users without knowledge of ontologies and their semantics. Our approach has successfully been applied in building the LHA (Leipzig Health Atlas) portal, which provides access to metadata, data, publications and methods from various research projects at the University of Leipzig.
