title： Problems in online scoring system
题目：网络阅卷中的问题
Part 1：About digital numbers and recognition algorithm
Abstract：It designs a group simple and easy-writing digital numbers and takes them as recognition identification codes integrated in the examination paper. This design effectively realizes the one-to-one correspondence between the student and his examination paper. It analyzes the recognition algorithm of the digital numbers in scanned examination paper, and solves many potential exceptions in the recognition process. The design and recognition algorithm are also applied to the automatic identification and marking of objective questions. The experimental results show that the proposed design and recognition algorithm have the advantages of small occupied space, easy-writing, rapid recognition, high rate of recognition and low cost etc.
Keywords: online scoring system, digital numbers, recognition algorithm, integrated design

Part2：About agreement analysis
Abstract: It defines a type of score data with threshold value from online scoring system, and proposes an effective intra-group agreement coefficient according to the effective scores. It also discusses the inter-group agreement based on intra-group agreement and completely combination cross of raters.

Keywords: threshold, effective score, agreement, online scoring system
