- [Nested prefix and postfix extension in OntoStudio-X](https://semafora-systems.com/test/): Nested prefix and postfix extension for predicates and frames available in OntoStudio-X
- [A look into the black box: traceability of AI algorithms in practice](https://semafora-systems.com/a-look-into-the-black-box-traceability-of-ai-algorithms-in-practice/): semafora is collaborating in the creation of the new Bitkom study "A look into the black box: traceability of AI algorithms in practice"
- [semafora releases OntoStudio X – a radical new hybrid semantic AI IDE](https://semafora-systems.com/semafora-releases-ontostudio-x-a-radical-new-hybrid-semantic-ai-ide/): The basic idea driving OntoStudio X is that many competing IT approaches have strengths and weaknesses. Nowhere else, however, is it as easy as in IT to bring the respective strengths of the systems together (if done in a smart way).
- [New Built-ins available for OntoBroker](https://semafora-systems.com/new-built-ins-available-for-ontobroker/): Built-ins are the data processing components of OntoBroker on whose processing results the defined logic functions then draw the appropriate conclusions (the reasoning). Built-ins can also be created by the user and can thus significantly extend the functionality of OntoBroker. All built-ins are written in Java and can be added hot-pluggable.
- [EU-GDPR: State-of-the-Art Anonymisation and Pseudonymisation of Data](https://semafora-systems.com/eu-gdpr-state-of-the-art-anonymisation-and-pseudonymisation-of-data/): Question: How to select adequate methods for anonymising and pseudonymising data?
- [What is meant by active ontologies?](https://semafora-systems.com/what-is-meant-by-active-ontologies/): Active ontologies do not only contain structure elements to describe relations between entities, but also elements that change the ontology or start a functional process if an entity or relation in the ontology changes. This is done fully automatically within an execution framework (in the case of semafora the inference engine OntoBroker) and therefore one does not need external programming languages to process the ontology, as it is the case e.g. with OWL using Jena.
- [Automated transfer of PDF-based workflow descriptions into executable ontologies](https://semafora-systems.com/automated-transfer-of-pdf-based-workflow-descriptions-into-executable-ontologies/): On behalf of Atos International, semafora helps with the fully automated transfer of PDF-based workflow descriptions into executable ontologies
- [Differences between ontology modeling approaches / Description Logic (DL) versus Higher-Order Logic](https://semafora-systems.com/differences-between-ontology-modeling-approaches-description-logic-dl-versus-higher-order-logic/): Ontologies are mainly known from the area of the Semantic Web. The Semantic Web uses the Web Ontology Language (OWL), whose various manifestations are essentially based on Description Logic (DL). The primary purpose of DL is to model domains, i.e., to describe concepts, roles, and instances, and represents a subset of First-Order Logic. A key feature of DL is that it follows the Open-World Assumption (OWA). The OWA is based on the assumption that an observer does not have complete knowledge about the world and therefore there are three logical states: true, false, and unknown. This approach is useful for a flexible and open information pool such as the Internet. However, for industrial applications (e.g., SQL), Close-Word Assumption has emerged as an economically preferable way to have complete information oversight for non-chaotic processes. For example, an airline must be able to rely on the fact that a passenger has not checked in if he or she has been assigned a seat and it is empty. When "reasoning" with OWL, this remains an open question. The common approach to remedy this with downstream so-called "closure axioms", (e.g. "man is not woman") would explode the modeling effort for the exemplary unoccupied seat.

- [Digital Twin](https://semafora-systems.com/capabilities/digital-twin/): A Digital Twin is a digital model that accurately reflects a physical entity. This could be a product (like a turbine or vehicle), a process (like a manufacturing line or supply chain), or even a whole organization. The key feature of a digital twin is that it’s connected to its real-world counterpart through data. Sensors and data feeds from the physical object continuously update the digital twin, so the twin changes in real time as the physical object changes. Likewise, any simulation or scenario run on the twin can be informed by real-world conditions.
- [Data Integration](https://semafora-systems.com/capabilities/data-integration/): Data Integration refers to the process of combining data from multiple disparate sources and delivering a unified, consistent dataset for use in business intelligence, analytics, and day-to-day operations. In simpler terms, it means bringing together all your data – whether it’s in different databases, applications, or cloud services – into one cohesive “single source of truth.” This usually involves extracting data from source systems, transforming it into a common format, and loading it into a target system (such as a data warehouse or data lake). Data integration can handle structured and unstructured data, and it encompasses various techniques like ETL (Extract, Transform, Load), real-time data streaming, API-based integration, and data virtualization. The end goal is a complete and accurate 360° view of your information assets, eliminating duplicate data and inconsistencies. When done right, data integration ensures that everyone in your organization is working from the same reliable data, which is essential for effective analytics, reporting, and AI initiatives.

- [OntoBroker](https://semafora-systems.com/technology/ontobroker/): OntoBroker (OB) is an industrial-strength reasoning engine designed for active ontologies. Unlike many inference engines that remain stuck in academic prototypes, OntoBroker has been refined through decades of real-world enterprise deployments since the early 2000s. At its core, it runs the ObjectLogic stack—the successor to F-Logic 2—delivering a proven combination of expressivity, performance, and explainability for knowledge-driven systems.

- [OntoBroker Help](https://semafora-systems.com/resources/ontobroker-help/): The paradigm of semantic data processing, which has been attracting increasing attention since the early 2000s, draws on the philosophical approach of ontology, which was established by Parmenides around 500 BC. With this approach, reality can be described both abstractly and concretely. The tradition of ontological "modelling" was extended in modern times by mathematical forms of description, such as horn logic. With the logical programming languages developed in the 70s and 90s, such as Prolog and F-Logic, it is possible to describe complex relationships - as the philosophers did - and to use them as a form of artificial intelligence. Thus, new knowledge is created on the basis of complex connections - the so-called semantic AI.
