hc-ov-core: A end-to-end process support platform for human-centred ontology verificaiton

This repository provides the implementation of hc-ov-core an extenisble platform that supports ontology engineers in creating human-centred ontology verification on crowdsourcing platforms such as Amazon Mechanical Turk.

The main features of the platform include:

• Providing tool-support for conducting human-centred ontology verification.
• Orchestration of the whole human-centred ontology verification process from prepartion to result processing.
• Storing ontologies, extracted sub-ontologies and meta-data about verification in a centralised way.
• Extensions for new types of verifications, crowdsourcing platforms, context providers and processing methodologies through plugins.

Architecture

An overview of the platform implementation is best provided by considering following component diagram:

The components implemented with this repository include all components in the component Platform Core and it's interfaces. Further, a default IProcessorPlugin plugin RawDataProcessorPlugin is implemented that allows to expose unprocessed raw results from a crowdsourcing platform. Also note that the component Ontology Metrics is not yet implemented.

All implemented external interfaces (e.g. UploadOntology or TaskSpec) following the REST over HTTP paradigm. An OpenAPI 3.0 specification can be found in src/main/resources/openapi.yaml and a Swagger page is hosted under the path /swagger-ui/index.html. For an exemplary workflow and interaction with the platform the postman collection HCOV-CORE PIZZA.postman_collection.json can be used.

For information on how to extend the platform by implementing plugins refer to hc-ov-sdk. Sample implementation of plugins providing information can be found at hc-ov-pizza-verification-plugins , hc-ov-amt-connector and hc-ov-sample-plugins.

Used technologies

To implement the platform following technologies are used:

• Java 18
• Spring Boot 2.6.7
• Apache Jena 4.4.0
• Thymeleaf 3.0.15

Running the platform

To run hc-ov-core Apache Maven 3.6.3 is required. To start the platform locally run ./mvnw spring-boot:run in the root directory of this repository.
