Data is the new oil. — Clive Humby, Kellogg School, 2006.

I am a postdoctorate researcher at the University of Ljubljana, Faculty of Computer and Information Science. My research interests are related to broad Information Retrieval and Information Extraction fields, which I also researched in my diploma thesis and PhD thesis.

Information Extraction (IE) refers to automatic extraction of structured information from unstructured sources. As a task it can also be seen as flling slots into a database from text. It must pre-process, recognize and convert information from textual documents (e.g web pages, reports, books), structural (e.g. web page structure, indexes) or usage data (e.g. query logs) into human and machine understandable format. As a family of techniques IE combines segmentation, classification, association and clustering. They can be roughly divided into pattern-based and machine learning-based (ML) approaches. The first use manually defined rules or can also learn them for specific type of documents using seed expansion. The latter consist of probabilistic (e.g. sequence models) and induction (e.g. linguistic, structural models) approaches and are currently the main focus of the research in IE community. In knowledge management and semantic web, a machine can understand the data if it is represented as an ontology. Therefore IE techniques can be used for automatic ontology creation and also population.

"Once you have a truly massive amount of information integrated as knowledge, then the human-software system will be superhuman, in the same sense that mankind with writing is superhuman compared to mankind before writing." Doug Lenat, June 21, 2001
