The invention relates to the field of
engineering cost, in particular to an
engineering cost index analysis method based on
reinforcement learning, which comprises the following steps of: identifying a table contour and a standard
font contour in file image data, generating optimized image data, extracting a pointing keyword as a
label, and forming a clustering set based on
semantic similarity clustering; visual
similarity analysis is carried out by reserving a table contour, a common
label is set, a mapping association network of a keyword
label and the common label is constructed, and intelligent
processing of data uploaded by a user side is achieved. When the common label is successfully associated, a key data area is positioned according to area information, and local analysis is carried out; and if not, carrying out traversal analysis and semantic understanding on the complete table structure. According to the method, manual marking is replaced by automatic
feature extraction, structured association of
engineering knowledge is established, differentiation
processing strategies are intelligently switched according to the matching degree, and the training
data quality and the generalization ability of the model in a complex engineering scene are improved.
