In this paper we present 1BC, a rst-order Bayesian Classiier. While the propositional Bayesian Classiier makes the naive Bayes assumption of statistical independence of atomic features (one attribute taking on a particular value) given the class value, it is not immediate which atomic features to use in the rst-order case, where features may be constructed from arbitrary numbers of literals. Ou...

Brokerage is an essential yet understudied function in social life. In one of the classics in the field of sociology, Georg Simmel differentiated three types of the “third” which help to analyse brokerage: the disinterested mediator or arbitrator, tertius gaudens and divide et impera. Studies that conceptualise traffickers and smugglers as brokers are extremely rare. Scholars lack a typology wh...

Steering their swimming direction toward the light is crucial for the viability of Volvox colonies, the larger members of the volvocine algae. While it is known that this phototactic steering is achieved by a difference in behavior of the flagella on the illuminated and shaded sides, conflicting reports suggest that this asymmetry arises either from a change in beating direction or a change in ...

This paper deals with learning rst-order logic rules from data lacking an explicit clas-siication predicate. Consequently, the learned rules are not restricted to predicate deenitions as in supervised Inductive Logic Programming. First-order logic ooers the ability to deal with struc-tured, multi-relational knowledge. Possible applications include rst-order knowledge discovery, induction of int...

This paper describes a large scale method to extract semantic relations between named entities. It is characterized by a large number of relations and can be applied to various domains and languages. Our approach is based on rule mining from an Arabic corpus using lexical, semantic and numerical features. Three primordial steps are needed: Firstly, we extract the learning features from annotate...
