Imputation of missing technology classification in worldwide patent data
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'The file tech_all.txt contains identifiers for patent first filings (corresponding to appln_id in PATSTAT), technology fields and technology sectors from PATSTAT table TLS230_APPLN_TECHN_FIELD. The file ipc_all.txt contains identifiers for patent first filings (corresponding to appln_id in PATSTAT) and International Patent Classification (IPC) from PATSTAT table TLS209_APPLN_IPC. The file cpc_all.txt contains identifiers for patent first filings (corresponding to appln_id in PATSTAT) and Cooperative Patent Classification (CPC) from PATSTAT table TLS224_APPLN_CPC. Missing information has been imputed from equivalents and other second filings. The files also contain a variable indicating the source of information ('source'): The field 'source' indicates where the information on technology classification comes from : 1 = information av' .
