This project provides the source code for WoolNet (see demo): a visual system to help explore connections and thematic sub-graphs for Wikidata.

• Node: v16.17.1
• Java: openjdk 11

• In /frontend call npm i to install dependenciaes.
• Load /rdf-entity-path into Eclipse IDE.
• To create data to populate the graph, use graph-compress library, the data must be in Compressed Graph format.
• To create test data, see the README in the python folder.

• Set in /frontend/.env the following environment variables as correspond to your setting.

BASE_URL = "https://urldeejemplo.ejemplo"		# Url of the application
WEB_SOCKET_URL = "wss://urldeejemplo.ejemplo"	# Url of the WebSocket

• Run build.ps1.
• The file that runs the application exports to /export.
• Run the file with the following parameters:
  • -Xmx59g : RAM available.
  • -Dgraph-data= : Pass the parameter the path to the file with graph data.

For example:

java -jar -Xmx59g -Dgraph-data="latest-truthy_small" rdf-entity-path-0.0.1-SNAPSHOT.jar

The data format used should be Adjacency Cache format (see the python folder).

• Set in /frontend/.env the following environment variables.

BASE_URL = "http://localhost:8080"
WEB_SOCKET_URL = "ws://localhost:8080"

• Run the following commands:

cd frontend
npm run dev

• The file frontend/public/index.html will show the live changes.

• Run the following commands:

npm run build

• Use RunServer.launch to launch

The classes found in rdf-entity-path/src/main/experiments can be used for experiments/testing and should be compiled to a .jar.

• NeighborsTest.java: Loads a graph measuring memory and time usage. Later it measures the time needed to obtain the neighbours of a particular node. NodesNeighborsTest.launch contains the parameters.
• PathFindTest.java: Loads a graph and measures the memory and time usage for finding paths that connect two or more nodes. PathFindTest.launch contains the parameters.
