IntroductionCommercializing Artificial Intelligence platforms, products and tools is much more challenging than traditional software. This is because1. It represents a revolution in computing2. Its new to IT staff, conceptually and in practice3. It requires adoption of a substantially different way of thinking about computing4. It requires a different way of thinking about business.Human IntelligenceIn the U.S., every year, about 2.6 million people have some type of brain injury, caused by trauma, stroke, tumor, or other illnesses. The greatest factor in functional recovery after brain injury comes from the brain’s ability to learn, called neuroplasticity. After injury, neuroplasticity allows intact areas of the brain to adapt and attempt to compensate for damaged parts of the brain. Developing brains are more able to regenerate than adult brains.It’s possible that one day we will discover ways in which to restore cognitive function to higher levels than we can today, maybe t

making process will be essential to accomplish precision medicine goals. However, quantity and diversity of biomedical data, and the spread of clinically relevant knowledge across myriad biomedical databases and publications makes this exceptionally difficult. To address this, we developed the Clinical Knowledge Graph (CKG), an open source platform currently comprised of more than 16 million nodes and 220 million relationships to represent relevant experimental data, public databases and the literature. The CKG also incorporates the latest statistical and machine learning algorithms, drastically accelerating analysis and interpretation of typical proteomics workflows. We use several biomarker studies to i

RDFox is a high performance knowledge graph and semantic reasoning engine developed by Oxford Semantic Technologies. This short article will help you understand the key concepts behind RDFox and when to use them in your applications.Knowledge GraphsA knowledge graph is composed of a graph database to store the data and a reasoning layer to interpret and manipulate the data.Relational databases store data in structured records whereas graph databases store data points as nodes which are connected with edges if they share some form of relationship.Data stored in a graph can be accessed with a query which will “hop” along the edges to find the requested nodes.ReasoningReasoning is the process of materialising rules which apply to the data. Materialising a rule means adding new nodes or edges to the graph when it is satisfied. These new nodes and edges match the rule’s “pattern”.A rule can be as simple as an “If… then…” statement.For example: “If a city is located

the task should accurately quantify the “distribution shift” in the data. Having precise control of this shift could allow us to understand the drawbacks of our learning methods, and build systems which can generalize over multiple tasks but still remember the old ones. Data distribution

world factual information that can augment the limited labeled data to train a machine learning algorithm. The term Knowledge Graph (KG) is in vogue as for many practical applications, it is convenient and useful to organize this background knowledge in the form of a graph. Recent academic research and implemented industrial intelligent systems have shown promising performance for machine learning algorithms that combine training data with a knowledge graph. In this article, we discuss the use of relevant KGs to enhance the input data for two applications that use machine learning—recommendation and community detection. The KG improves both accuracy and explainability.Machine learning algorithms trained with a large labeled data have shown promising performance in solving pr

Neptune Streams is now available in production from engine release 1.0.2.2.R2. Neptune Streams can be enabled or disabled using the cluster parameter neptune_streams. Once enabled, you can access Neptune Streams using the HTTP GET requests to REST APIs /sparql/streams or /gremlin/streams. The response will be a JSON feed of the operations and the changes to the graph. The lab mode setting “streams” in the database cluster parameter neptune_lab_mode will be removed after the current release. When Neptune Streams are enabled, you incur I/O and storage charges associat

Direct online marketing and sales are nowadays an essential part of almost any business that addresses an end consumer, such as in tourism. On the downside, the data and content required for such marketing and sales are typically distributed, and difficult to identify and use, especially for small and medium enterprises. Further, a combination of content management and semantics for automated online marketing and sales is becoming practically feasible now, especially with the global adoption of knowledge graphs. A design and feasibility pilot of a solution implementing semantic content and ...
