In a delegative democracy, voters can delegate their vote to any other voter in the system and can change their delegations at any point in time. We look at the impact of delegations on an online delegative democracy platform.
Markov logic is a robust approach for probabilistic relational knowledge representation that uses a log-linear model of weighted first-order formulas for probabilistic reasoning. This log-linear model always exists but may not represent the knowledge engineer’s intentions adequately.
Word segmentation can be considered as a fundamental task in natural language processing. The process to tokenize a given text is the rst step in further analyzing it using for example POS-Tagging, semantic analysis or automated translation mechanisms.
In recent years, answering keyword queries on graph-structured data has emerged as an important research topic. There are two main reasons behind that. On one hand, at the beginning of their search process, many users are uncertain what exactly they are looking for, or which terms should be used to express their query.
In order to leverage to potential for connected education unfree alternatives like coursera, udacitz, iversitz an many more are entering the market. Those platforms offer a great user experience while consuming and creating content. Typical Learn management systems like OLAT do not have such a great user experience. Both platforms do not really support creating courses in a collaborative way. Mediawiki a software used for wikipedia but also for the german ZUM-Wiki is a spread alternative for learning materials. The problem is that the main purpose of media wiki is to build an encyclopedia and lack user experience for creating and consuming courses.
There is an increasing availability of data encoded in the W3C standard Resource Description framework (RDF). In a near future, this may pose severe problem to classical approaches for query answering based on a single computing node. A natural approach to tackle this challenge is to resort to distributed RDF stores that combine several computing nodes in one virtual system. In general, distributed RDF stores splits an RDF graph into several partitions that are assigned to computing nodes. Hence, the partitioning strategy influences the efficiency of query execution. This is true as the computation of one single result can require triples stored on several different computing nodes.
Detection of bus lines from GPS data, captured by mobile phones, has many applications in urban transportation. Traditional approaches use distance measures between bus route data and the GPS history to identify the most likely bus lines that a user is traveling in. In the talk I am going to present a Markov model approach that allows to exploit precise detection of the "waiting at bus stop"-event in a natural way. This is joint work with Sven Milker, who is currently writing his master's thesis on this topic.
The Semantic Web aims at converting the current web into a web of data. All data in the Semantic Web - be it Linked Data or publicly available Triplestores - adhere to the same data model. They are also both queryable through an either Link-Traversal based query approach or through SPARQL.
