Dynamics of Term Relatedness
Finding semantically related terms has become important for Web search, online advertising and other scenarios. However, the semantic relatedness of terms, being socially defined, is an evolving phenomenon and changes over time. This projects aims to establish a way to recognize the changes in semantic relatedness of terms over time. For instance if the Olympics are announced to be held in a particular city, the name of the city suddenly becomes much more related to the term "olympics". This project uses the real-time Web to sense such changes in semantic relatedness. The new related terms can be used to adapt advertising campaigns by including new, temporarily relevant terms, or to change the behavior of other online systems.
hyProximity
hyProximity is a system for keyword recommendation based on the semantic proximity of concepts. It uses DBPedia - a Semantic Web version of Wikipedia to find concepts that are semantically related. As opposed to the systems that rely on co-occurrence of terms in text, this projects aims to find the related terms based on their meaning. The system is capable of recognizng the context of relevancy (two concepts are not related in the same way in all situations; e.g. clay is a concept close to artistic modeling, but this proximity is irrelevant if we are dealing with clay in the context of clay mining and raw material processing). The concept suggestions provided by the system tend to be more novel and surprising to the user while remaining highly relevant. hyProximity is used by hypios in the search of potentially interesting topics for Open Innovation problem solving, but can also be used in online advertising, and similar use cases.

Expert Finding on Linked Data
As a part of my PhD thesis I am working on good ways to search for experts on Linked Data. As opposed to legacy approaches that took only one expertise hypothesis (assumtpion about what does it take to be an expert), I try to levarage the flexibility and multiple purposes of Linked Data to allow a more sophisticated approach.

Smiley Ontology
People use emoticons every day as the easiest and most interesting way to express their emotions, actions and affective states. But the exchange of emoticons across different systems is limited. Smiley Ontology is an ontology that aims to enable interchange of emoticons between different systems, without any loose of its semantics, and to enable the capture of semantics of emotions and emotional states that can be found in smileys.

Online Presence
The project is aimed at enabling the integration and exchange of data related to a user’s presence in the online world. As opposed to static user profiles and the interoperability in that domain, well supported by the FOAF Vocabulary, the Online Presence project targets the interoperability of dynamic properties that determine a user’s current state of presence (e.g., custom messages, IM statuses etc.).

TagFusion
The project addresses the problem of collaboration and integration of tagging metadata from multiple collaborative tagging systems. Special attention has been given to the strategies for attracting collaborative tagging systems to integrate using TagFusion, as well as to the possibility to involve artificial entities into the annotation process in accordance with the Semantic Web vision.

Talaria System
TALARIA System ( The Autonomous Lookup And Report Internet Agent System ) is a multi-agent system for gathering information from the Web. The system periodically inspects Web sites for appearance of relevant new content, and informs users about it.

Java Examples
In 2004, while still a student, Milan Stankovic founded a blog for publishing students' works in Java programing language with intention to crate a repository of simple examples provided by students that would be useful to other students learning Java programing language. By now, many other students have joined the initiative, and created many works on various topics such as: Java, Web Applications, Design Patterns, Algorithm Theory...
