 ## Contents
 
-The material related to the evaluations in this publication will be added soon. 
+In the paper, DIVIDE is explained through a running homecare monitoring example. This example is also used for the paper's evaluations.
+
+This folder contains three subfolders:
+
+* [`ontology`](ontology): This folder contains all files of the Activity Recognition ontology, used for the running homecare monitoring example, that is discussed in the paper. This is a snapshot of the [DAHCC ontology](https://github.com/predict-idlab/DAHCC-Sources), complemented with an ontology file [`KBActivityRecognition.ttl`](ontology/KBActivityRecognition.ttl) that represents all extra definitions related to the knowledge-driven activity recognition. All files in this folder together represent the Activity Recognition ontology. This ontology is also used for the paper's evaluations.
+* [`evaluations`](evaluations): This folder contains supportive material related to the evaluations performed in the paper.
+* [`eye-implementation`](eye-implementation): This folder contains some more details concerning the implementation of the initialization and query derivation of DIVIDE with the EYE reasoner.

+# Context-aware & privacy-preserving homecare monitoring through adaptive query derivation for IoT data streams with DIVIDE
+
+This folder contains supportive material for the evaluations in the paper "Context-aware & privacy-preserving homecare monitoring through adaptive query derivation for IoT data streams with DIVIDE", which is submitted to the Special Issue on Semantic Web Meets Health Data Management of the Semantic Web Journal.
+
+## Contents
+
+The folder contains supportive material for the following evaluations:
+
+* [`divide-performance`](divide-performance): The material in this folder is related to the performance evaluation of DIVIDE. It corresponds to the evaluation set-up and results in the Sections 8.1 and 9.1 of the paper ("Performance evaluation of DIVIDE").
+* [`real-time-comparison`](real-time-comparison): The material in this folder is related to the real-time evaluation of the DIVIDE approach, compared to other alternative approaches that use real-time semantic reasoning. It corresponds to the evaluation set-up and results in the Sections 8.3 and 9.2-3 of the paper ("Real-time evaluation of derived DIVIDE queries").
+
+The context used for the evaluations is represented by the [`context.ttl`](context.ttl) file. This file contains all context triples in RDF/Turtle syntax.

+# Context-aware & privacy-preserving homecare monitoring through adaptive query derivation for IoT data streams with DIVIDE
+
+This folder contains supportive material for the evaluations in the paper "Context-aware & privacy-preserving homecare monitoring through adaptive query derivation for IoT data streams with DIVIDE", which is submitted to the Special Issue on Semantic Web Meets Health Data Management of the Semantic Web Journal.
+
+## Contents
+
+The material in this folder is related to the performance evaluation of the DIVIDE system itself. It corresponds to the evaluation set-up and results in the Sections 8.1 and 9.1 of the paper ("Performance evaluation of DIVIDE").
+
+The [`divide-queries`](divide-queries) subfolder contains the configuration details of the DIVIDE query definitions that are being used in this evaluation. These include the DIVIDE queries corresponding to the toileting and brushing teeth activity rules. For both activities, the root folder of the corresponding DIVIDE query contains the internal representation of this DIVIDE query. For the toileting query, the end-user definition (as a series of SPARQL queries) is also included in the `sparql` subfolder.
