simpleowlapi
A light-weight wrapper for the OWLAPI
simpleOWLAPI is a light-weight wrapper for the OWLAPI that enables faster programmatic development of OWL ontologies with more concise code using the power of the Manchester OWL Syntax and related parsers. The wrapper does not make use of all the features of the more powerful OWLAPI. Rather, it is designed specifically for rapid and concise ontology construction in workflows involving semantic data engineering. It can also be used in contexts such as educational and demonstration settings in courses, workshops and tutorials. ... -

The presented tool, called ONTOOL, allows for creating UML class diagrams on the basis of the selected OWL domain ontologies, and verifying if the diagrams are compliant with the ontologies. ONTOOL additionally allows for normalizing any syntactically correct and consistent ontology expressed in OWL. ONTOOL has been tested with a number of test cases, and empirically evaluated through conducting an experiment. The tool has been implemented as a proof of concept of the methods proposed in the Doctoral Thesis: Małgorzata Sadowska, "Creating and validating UML class diagrams with the use of domain ontologies expressed in OWL 2", Wroclaw University of Science and Technology, 2020.

OLiA
OWL/DL ontologies for linguistic annotations
MOVED TO https://github.com/acoli-repo/olia. The Ontologies of Linguistic Annotations (OLiA) provide an OWL/DL taxonomy of data categories as a reference for linguistic annotation (OLiA Reference Model), plus OWL/DL models for a large number of annotation schemes (OLiA Annotation Models) and their relationship to reference data categories (OLiA Linking Models). The OLiA Reference Model itself is linked to community-maintained repositories such as GOLD (http://linguistics-ontology.org/) and ISOcat (http://www.isocat.org) The OLiA ontologies were originally developed as part of an infrastructure for the sustainable maintenance of linguistic resources (http://www.sfb441.uni-tuebingen.de/c2/index-engl.html), their fields of application include the formalization of annotation schemes, concept-based querying over heterogeneously annotated corpora, and the development of interoperable NLP pipelines. -

UFO-Cytoscape
Ontology-based semantic similarity calculation and visualization
Motivation: Biomedical ontologies have been growing quickly and proven to be useful in many biomedical applications. The use of this data is mainly based on semantic similarity calculation between ontology terms and between annotated biomedical entities. Many semantic similarity measures have been proposed for such calculation. Results: A number of tools have been developed on different platforms for ontology visualization and semantic similarity calculation. -

OWL Machine Learning
Machine learning algorithm using OWL
...Usually, these are very time-consuming and complex tasks because the features have to be manually crafted. The features are aggregated, combined or split to create features from raw data. This project makes use of ontologies to automatically generate features for the ML algorithms. The features are generated by combining the concepts and relationships that are already in the knowledge base, expressed in form of ontology. -

Authors: Shahin Mehdipour Ataee & Zeki Bayram Eastern Mediterranean University Our choreography engine takes as input semantic web service specifications written in the Flora-2 dialect of F-logic. Furthermore, we prove the equivalence of ASMs (evolving algebras) and evolving ontologies in the sense that one can simulate the other, a first in literature. Finally, we present a visual editor which facilitates the design and deployment of our F-logic based web service and goal specifications.

Ontology Evaluation/LD Principles
Evaluate Ontology according to Linked data principles
...To ensure the achievement of these objectives, it must meet the criteria set by Tim Berners-Lee as lined data principles: all ontology elements must be identified with URIs, these URIs must be dereferenceable, the ontology language must be semantically correct and ontologies should be linked together (via common URIs). These principles are based on the underlying web and semantic web technologies, such as URIs, HTTP and knowledge representation languages such as RDF. This application evaluates an ontology according to the linked data principles and correct them if necessary.
