In multicellular organisms, there is a potential risk that cheating mutants gain access to the germline. Development from a single-celled zygote resets relatedness among cells to its maximum value each generation, which should accomplish segregation of cheating mutants from non-cheaters and thereby protect multicellular cooperation. Here we provide the crucial direct comparison between high- an...

In multispecies assemblages, phylogenetic relatedness often predicts total community biomass. In assemblages dominated by a single species, increasing the number of genotypes increases total production, but the role of genetic relatedness is unknown. We used data from three published experiments and a field survey of eelgrass (Zostera marina), a habitat-forming marine angiosperm, to examine the...

This paper reports on work in progress on extending the entity-based approach on measuring coherence (Barzilay & Lapata, 2005; Lapata & Barzilay, 2005) from coreference to semantic relatedness. We use a corpus of manually annotated German newspaper text (TüBa-D/Z) and aim at improving the performance by grouping related entities with the WikiRelate! API (Strube & Ponzetto, 2006).

We evaluate semantic relatedness measures on different German datasets showing that their performance depends on: (i) the definition of relatedness that was underlying the construction of the evaluation dataset, and (ii) the knowledge source used for computing semantic relatedness. We analyze how the underlying knowledge source influences the performance of a measure. Finally, we investigate th...

Association mapping (AM) methods are used in genome-wide association (GWA) studies to test for statistically signi€cant associations between genotypic and phenotypic data. Œe genotypic and phenotypic data share common evolutionary origins – namely, the evolutionary history of sampled organisms – introducing covariance which must be distinguished from the covariance due to biological function th...

An important topic in Semantic Web research is to learn ontologies from text. Here, assessing the degree of semantic relatedness between words is an important task. However, many existing relatedness measures only encode information contained in the underlying corpus and thus do not directly model human intuition. To solve this, we propose RRL (Relative Relatedness Learning) to improve existing...

Entity relatedness is a task that is required in many applications such as entity disambiguation and clustering. Although there are many works on entity relatedness, most of them do not consider temporal aspects and thus, it is unclear how entity relatedness changes over time. This paper attempts to address this gap by showing how entity relatedness develops over time with graph-based approache...

A developmental cascade model of autonomy and relatedness in the progression from parent to friend to romantic relationships across ages 13, 18, and 21 was examined among 184 adolescents (53% female, 58% Caucasian, 29% African American) recruited from a public middle school in Virginia. Parental psychological control at age 13 undermined the development of autonomy and relatedness, predicting r...

one of the most important issues in educational psychology is school engagement and academic achievement among students. based on self system model, a set of contextual factors (relations with teachers like perceived autonomy, structure, and involvement) through personal psychological characteristics (autonomy, relatedness, competence) is related to school engagement. the purpose of this study ...

Sentence comprehension involves timely computing different types of relations between its verbs and noun arguments, such as morphosyntactic, semantic, and thematic relations. Here, we used EEG technique to investigate the potential differences in thematic role computing and lexical-semantic relatedness processing during on-line sentence comprehension, and the interaction between these two types...
