(IEEE, 2011-10-14)Although many real world problems are dynamic in nature, the study of Genetic Programming in dynamic environments is still immature. This paper investigates the application of some recently proposed semantic-based crossover ...
-
(Springer, 2012-10)In recent years, a web phenomenon known as Volunteered Geographic Information (VGI) has produced large crowdsourced geographic data sets. OpenStreetMap (OSM), the leading VGI project, aims at building an open-content world ...

(ACM, 2011-07-12)This paper examines how the semantic locality of a search operator affects the fitness landscape of Genetic Programming (GP). We compare the fitness landscapes of GP search when standard subtree mutation and a recently ...

(Il Mulino, 2009-01)This paper investigates what is specifically nominal in lexical semantics and how it relates to nouns as morphosyntactic objects. Nouns are argued to refer primarily to kind-level sorts, which define categories of entities ...

Semantically-based crossover in genetic programming : application to real-valued symbolic regression (Springer, 2011-06)We investigate the effects of semantically-based crossover operators in Genetic Programming, applied to real-valued symbolic regression problems. We propose two new relations derived from the semantic distance between ...

(Springer, 2012-10-15)A cognitively plausible measure of semantic similarity between geographic concepts is valuable across several areas, including geographic information retrieval, data mining, and ontology alignment. Semantic similarity ...

(Springer-Verlag, 2012-04)In recent years, geographic information has entered the mainstream, deeply altering the pre-existing patterns of its production, distribution, and consumption. Through web mapping, millions of online users utilise spatial ...

Improving the generalisation ability of genetic programming with semantic similarity based crossover (Springer, 2010)This paper examines the impact of semantic control on the ability of Genetic Programming (GP) to generalise via a semantic based crossover operator (Semantic Similarity based Crossover - SSC). The use of validation sets ...

(Consiglio Nazionale delle Ricerche. Istituto di Matematica Applicata e Tecnologie Informatiche, 2007)In the recent Computer Science literature, contexts have been proposed mainly to formalize context dependent background knowledge. In this paper we discuss the importance of the application of contexts as explicit ...

(Springer-Verlag, 2011-03)In recent years, the proliferation of Volunteered Geographic Information (VGI) has enabled many Internet users to contribute to the construction of rich and increasingly complex spatial datasets. This growth of geo-referenced ...
