Using TTSCT to identify Snomed concepts within clinical texts
Project objectives ,[object Object],[object Object]
CliniDAL indexing process ,[object Object],[object Object],[object Object],Request_id is being used as an internal unique id in the SWAPS database referring to every single patient medical record. Request_id_list records the list of request ids whose text contains a specific concept and freq records how many times the concept appeared on the corresponding text. Description Text Text Integer Text Text Datetime Datetime Datetime Conceptid Request_id_list Frequency Version_id Index_created_date_time First_seen_date_time Last_seen_date_time Data_type Column_name
Some statistics from the index ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
