A Collaborative Filtering Method for Operation Maintenance Behavior in Power Monitoring Systems

Algorithm 1

Workflow of operation and maintenance behavior extraction algorithm.

Input: a real-time operating instruction character string I of a user, the current user id user_id, and resource keyword database source_db

Output: behavior information{user_id, source_id} containing user id and resource id

1 Divide instruction I into multiple words

2for word in each words. /Traverse the words in the instruction/

3   use the word to query the keyword database to obtain the resource id source_id

4   if (successful query)

5      output the behavior information {user_id, source_id}

6   end if
