|- df4rule.py

• Prerequiste

  • You need csv files that are generated with finiancial_news_api
  • Those files should be located in "visualization_code/rule_base_datasets/*.csv"

• This code extracts relations with rule-based patterns.

  • (S + V + O) -> (head: S, relation: V, tail: O )

|- df4ssan.py

• Prerequiste
  • We recommend you run SSAN independently, and make sure all relation extraction.json file from SSAN code saved in "output/*/SSAN_result_all_relation.json"
• This code convert json file to dataframe and concat all the dataframes from various companies.
