<3> Data requirement

a_p_list_train.txt: paper neighbor list of each author in training data

p_a_list_train.txt: author neighbor list of each paper in training data

p_p_citation_list.txt: paper citation neighbor list of each paper

v_p_list_train.txt: paper neighbor list of each venue in training data

p_v.txt: venue of each paper

p_title_embed.txt: pre-trained paper title embedding

p_abstract_embed.txt: pre-trained paper abstract embedding

node_net_embedding.txt: pre-trained node embedding by network embedding

het_neigh_train.txt: generated neighbor set of each node by random walk with re-start

het_random_walk.txt: generated random walks as node sequences (corpus) for model training

<4> Model evaluation for different applications

4-1 link prediction (author-author collaboration, type-1)

step-1: run input_data_class.a_a_collaborate_train_test() in input_data_process.py to set author-author collaboration train/test data

step-2: run [author collaboration link prediction] part in application.py to obtain evalution result

4-2 link prediction (author-paper citation, type-2)

step-1: run input_data_class.a_p_citation_train_test() in input_data_process.py to set author-paper citation train/test data

step-2: run [author paper citation link prediction] part in application.py to obtain evalution result

4-3 node recommendation (venue recommendation)

step-1: run input_data_class.a_v_train_test() in input_data_process.py to set author-venue train/test data

step-2: run [venue recommendation] part in application.py to obtain evalution result

4-4 node classification/clustering (author classification/clustering)

step-1: run [author classification/clustering] part in application.py to obtain evalution result

<5> Others

5-1 raw_data_process.py: raw data (academic_small.txt) processing and data preparation

5-2 input_data_process.py: generating het_rand_walk for model training, train/test data for different tasks, etc.

5-3 DeepWalk.py: generating pre-train node embedding
