+# Cora Node Classification
+To evaluate the trained graph and the embeddings the task of node classification will be executed. First, the data of cora will be imported into a networkX graph, which will be saved in a pickle file to use it for the training of the embeddings with our EP-SP algorithm. Afterwards the trained embeddings will be evaluated with LibLinear L2-Logistic Regression provided from sklearn over a transductive setting with 1000 random nodes for validation, 1000 random nodes for testing and 20 random nodes per class for training. For each iteration where the sets are newly splitted the random seed is set to to the iteration number.
+Graph building is provided on cora.py, the evaluation on node_classification.py.

+# Building Cora Graph
+With this skript a networkX graph will be created from the raw data.
+Cause of using numpy for bow-array-representations the data has to be saved in pickle format, and not f.e. json.
+
+# Required Data
+- Cora raw data saved in /data/cora/raw/
+
+# Dependencies
+-networkx	for building the graph
+-numpy		to save one-hot vocabulary vectors
+-pickle		to save data in a pickle file

+	-n / --nodes	Path to cora file containing nodes
+	-e / --edges	Path to cora file containing edges
+	-o / --output	Path where the graph should be saved
