Automatizované hodnocení kvality dokumentů
Čačková, Petra
Dissertation thesis deals with the possibilities of automated documents quality evaluation. The quality is specified as the formal quality, particularly the typographic aspects of documents processing are emphasized. Documents represent the organization but they are not often checked for their formal quality level. Automated checking and evaluation would be helpful. In many areas, the attention is paid to the quality. The documents formal quality is not the main area of interest. In the literature, mainly the aesthetic or typographic aspects are concerned. However, the research showed that high-quality documents have a positive effect on readers so that the documents quality is important. The documents analysis made for different purposes is the present trend and the methods are focused on objects recognition in the page as well as on the objects classification. In this context, a number of various methods working at different documents levels were developed. Especially the artificial intelligence methods, which are primarily used for classification, can be helpful. Existing methods can be used for further work. In this thesis, a procedure for methods assessment was designed, which concentrates on methods' suitability for automated evaluation of documents quality. The selected methods should provide enough relevant data for evaluation. The important part of the thesis is the mathematical model design that describes the document by a set of parameters. Selected parameters should reflect the relevant characteristics of the document at different levels, from page elements to the whole document. The set of parameters and their values build a formal image of the document, which is one of the inputs for the quality evaluation. The other input for the quality evaluation process is the set of rules for documents which consists mainly from the typographic rules. The rules which have a positive effect on the documents quality were selected. The essential contribution to the automated evaluation is the formalization of these rules by the mathematical apparatus. The formalized rules and the document model are the inputs to the quality evaluation process. A formalized evaluation of the parameters according to the selected rules is designed to discover the information about the document quality. For this purpose, an expert system is very suitable. Apart from evaluation, it can also provide explanation and advice. The entire procedure is demonstrated on the sample document and the evaluation is described. This thesis deals with the area which is still relatively unusual and integrates various disciplines, from typography through documents analysis to the artificial intelligence. The thesis is focused on analysis and design of the automated method for documents quality evaluation with a possible further development in the future.
