HistoricalTraversalNeo4j

Supporting Historical Traversals on graph database (Neo4j)

Getting Started

The primary configuration file is /config/settings.properties

Database csv files can be generated by CreateCSVFile.java files:

  https://github.com/ksemer/HistoricalTraversalNeo4j/tree/master/src/singleTypePointsEdge
  https://github.com/ksemer/HistoricalTraversalNeo4j/tree/master/src/multiTypeEdge
  https://github.com/ksemer/HistoricalTraversalNeo4j/tree/master/src/singleTypePointsEdge
  
  each one creates a csv file for a different represantation (as it is analysed in our paper)

Input file format of CreateCSVFile.java:

  - For example:
          src_id \t trg_id \t first_time_interval second_time_interval
          0 1 0,10 20,30
          1 2 2,14 16,18
  File example: https://github.com/ksemer/HistoricalTraversalNeo4j/blob/master/CSVFileInputExample.txt 

Query File Format

A file with each line representing an edge between two nodes in a specific time interval.

• For example: queryType, src_id, trg_id, time interval queryType: 1 --> conjunctive 2 --> disjunctive 3 --> at least

An input file example is in queries/dblp_query_example.txt and denotes a set of conjuctive queries.
