<h2>Abstract</h2>
<p>The ML Schema is a simple shared schema that provides a set of classes, properties, and restrictions that can be used to represent and interchange information on data mining and machine learning algorithms, datasets, and experiments.
It can be specialized to create new classes and properties. It can be mapped to more complex, specific ontologies on data mining and machine learning, and also used as a basis for markup languages and data exchange standards. </p>
<p style="text-align: center;">The namespace for ML Schema terms is <span class="repeated">http://www.w3.org/ns/mls#</span>.
</p>
<p style="text-align: center;">The OWL encoding of the ML Schema is available <a href="https://github.com/ML-Schema/core/blob/master/MLSchema.ttl">here</a>.

<p>
In the example, the run <code>:run100241</code> executes the implementation <code>:wekaLogistic</code>.
The run has on input the <code>:credit-a</code> dataset and its output is both the model <code>:wekaLogisticModel100241</code> and the model evaluation <code>:modelEvaluation100241</code>.
The run realizes the task <code>:task29</code>.
</p>
<p>
The implementation <code>:wekaLogistic</code> implements the algorithm <code>:logisticRegression</code>.
The implementation has five hyperparameters: <code>:wekaLogisticC</code>, <code>:wekaLogisticDoNotCheckCapabilities</code>, <code>:wekaLogisticM</code>, <code>:wekaLogisticOutputDebugInfo</code>, <code>:wekaLogisticR</code>.
Two of these hyperparameters are set for the run <code>:run100241</code>.
The hyperparameter <code>:wekaLogisticM</code> has value set to <code>-1</code> (expressed via the hyperparameter setting <code>:wekaLogisticMSetting29</code>), and the hyperparameter <code>:wekaLogisticR</code> that has its value set to <code>"1.0E-8"^^xsd:float</code> (expressed via the hyperparameter setting <code>:wekaLogisticRSetting29</code>).
</p>
<p>
The dataset <code>:credit-a</code> has several characteristics such as: <code>:decisionStumpAUC</code>, <code>:defaultAccuracy</code>, <code>:numberOfInstances</code>, <code>:numberOfMissingValues</code>.
</p>
<p>
The predictive model <code>:wekaLogisticModel100241</code> is evaluated (<code>:modelEvaluation100241</code>) based on the specified evaluation measure <code>:predictiveAccuracy</code>.
The value of the evaluation measure modeled via the model evaluation <code>:modelEvaluation100241</code> is <code>0.8478</code>.
</p>
<p>
The task <code>:task29</code> is defined on the dataset (<code>credit-a</code>) and on the evaluation specification <code>:evaluationSpecification1</code>.
The evaluation specification <code>:evaluationSpecification1</code> has parts: the evaluation procedure <code>:TenFoldCrossValidation</code> and the evaluation measure<code>:predictiveAccuracy</code>.
</p>

It is an output from an execution of a data mining algorithm implementation. Models have a dual nature. They can be treated as data structures and as such represented, stored and manipulated. On the other hand, they act as functions and are executed, taking as input data examples and giving as output the result of applying the function to a data example. Models can also be divided into global or local ones. A global model has global coverage of a data set, i.e., it generalizes the whole data set. A local model, such as a pattern set, is a set of local hypotheses, i.e. each applies to a limited region of the data set.</span></div><dl class="description"><dt>has super-classes</dt><dd><span class="dotted" title="http://www.w3.org/ns/mls#InformationEntity">information entity</span><sup title="class" class="type-c">c</sup></dd><dd><span class="dotted" title="http://www.w3.org/ns/mls#hasQuality">has quality</span><sup title="object property" class="type-op">op</sup> <span class="logic">some</span> <a href="#d4e459" title="http://www.w3.org/ns/mls#ModelCharacteristic">model characteristic</a><sup title="class" class="type-c">c</sup></dd></dl></div>
