Creating a model of the document representation allowing to improve the accuracy of the automated document classification
April 2021 – May 2022
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 industrial research part of the project is completed. The development of the prototype of the automated documentation classification model is in progress.
A smart assistant for a user support
September 2019 – May 2021
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) .

Creating a model for automated document classification, indexing and routing
April 2019 – April 2020
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.
