Elvis Koci | Database Research Group

I am a Ph.D. candidate, part of the IT4BI-DC Erasmus Mundus Doctorate program. Already in the last year of my studies, I have focused my research efforts on semi-structured documents, such as spreadsheets and web-tables. The objective of my thesis is to develop techniques for automatic analysis and processing of such documents. The main goal is to recognize tables, infer their structure, and expose this for further processing.

Research Interests

Analysis and Recognition in Semi-structured Documents
Data Lakes and Data Warehousing
