-# Implementation
+This repository contains the code created in the master thesis ["An Efficient Semantic Search Engine for Research Data in an RDF-based Knowledge Graph"](http://dx.doi.org/10.18154/RWTH-2020-09883 ) to implement a search engine for RDF-based metadata graphs based on Virtuoso, Elasticsearch and the developed mapping of the data.
 
-Contains the implementation of the SemanticSearch research.

+## Code documentation:
+
+The code documentation can be found under *./docs/index.html*.
+
+## Setup/Prerequisites:
+
+- Virtuoso
+    - Virtuoso.ini file 
+        - NumberOfBuffers >= 660000
+        - MaxDirtyBuffers >= 495000
+    - Define the following graphs as rulesets named "ruleset" for inference rules with `rdfs_rule_set ('<rulesetname>', '<graphname>') ;`
+        - http://www.dfg.de/dfg_profil/gremien/fachkollegien/faecher/
+        - http://www.w3.org/ns/org#
+        - http://xmlns.com/foaf/0.1/
+- Data mentioned in ["Sample Dataset for Search Engine Evaluation for Research Data in an RDF-based Knowledge Graph"](http://dx.doi.org/10.18154/RWTH-2020-09886 )
+    - All named_graphs, use virtuoso.db/graphs.db
+- Elasticsearch
+- Specified packages
+
+## How to use:
+
+1. (Re-)Build solution (Install/restore necessary packages)
+2. Start Virtuoso
+3. Start Elasticsearch
+4. Run *Coscine.SemanticSearch.Cmd.exe* with the necessary arguments
+5. Find your index name under `http://localhost:9200/_cat/indices/`
+6. Preview your index at `http://localhost:9200/<INDEXNAME>/`
+7. Preview data for index at `http://localhost:9200/<INDEXNAME>/_search`
+
+### Commandline arguments
+
+| Option        | Description | 
+| ------------- |-------------| 
+|-a, --action   | Required. Possible action: search, reindex, index, delete or add|
+|-m             | (Default: http://localhost:8890/sparql) The link to the SPARQL connection|
+|-e             | (Default: localhost) Server name of Elasticsearch|
+|--ep           | (Default: 9200) Port of Elasticsearch|
+|-d, --doc      | ID of metadata graph|
+|-q, --query    | (Default: *) Elasticsearch query|
+|--adv          | (Default: false) Set true for advanced Elasticsearch search syntax|
+|-u, --user     | (Default: ) Specify user or only public metadata records could be found|
