A model for analyzing document management workflows, based on process mining techniques

April 2023 – March 2025

The Objective:

The aim of the study is to develop a model for analyzing document management workflows based on process mining techniques, which includes:

  • A representation of document workflows based on business roles, which ensures the grouping of document processing tasks according to task types and executor roles, thus allowing the identification of the most typical workflows
  • Metrics for evaluating workflow efficiency in terms of workflows, structural units, employees, and time
  • Methods for analyzing actual document processing workflows, and for evaluating the compliance to the reference workflows

Successfully completed the industrial research phase. The publication has been accepted for presentation at the International Conference on Computer, Software, and Modeling (Paris, July 4-6). Work has begun on the experimental development phase of the research, where it is planned to develop and approbate a prototype of the document workflow analysis model.

Completed Projects

Creation a model of the document representation model for ensuring high precision of automated document classification

April 2021 – May 2022

The Objective:

The research is aimed at further improvement of the document classification framework developed earlier (see below the project “Creating a model for automated document classification, indexing and routing”). The research will be carried out in three directions:

  • The document feature model will be upgraded to include the representation of the document structure
  • The framework will be expanded to incorporate the means of cluster analysis of the historic documents aimed at creating a stable document classes
  • The framework will be expanded to deal with both digital and scanned documents

The project is successfully completed.

A smart assistant for user support

September 2019 – May 2021

The Objective:

The aim of the research project is to create a smart assistant service for the software product support team to deal with the frequent problems and questions. The smart assistant would act as a flexible mediator between a user and a support specialist. The user support process thus is represented as an interaction between three involved actors – the User, the (support) Specialist and the Assistant (software) .

Creation of an Automated Process Model for Document Classification, Indexing, and Routing

April 2019 – April 2020

The Objective:

The aim of the research project is to create a model for smart capturing of the digital documents. Smart capturing comprises document automated categorization according to one or several categories (document type, customer etc.), document indexing with appropriate metadata (document number, creation date, person names involved etc.) and routing to a proper assignee, role or workflow.
