\n The reconstruction of pedigrees from genetic marker data is relevant to a wide range of applications.

Statistical significance of edge strengths can be evaluated using model scoring criteria tests, cross-validation and bootstrapping. BNs are an excellent tool for reverse-engineering biological (e.g., physiologic and genetic) networks from “flat” datasets (e.g., generated by the large-scale, or candidate gene, association studies, or microarray gene expression experiments). In this chapter we review various applications of BN methodology to modern human genomics. An example application is detailed. We also discuss various technical aspects of BN reconstruction, with a special emphasis on scalability in the context of modern “omic” data.\n

The inference network model treats similarity searching as an evidential reasoning process in which multiple sources of evidence about compounds and reference structures are combined to estimate resemblance probabilities.Many methods have been developed to capture the biological similarity between two compounds for use in drug discovery. A variety of similarity metrics have been introduced, the Tanimoto coefficient being the most prominent. Many of the approaches assume that molecular features or descriptors that do not relate to the biological activity carry the same weight as the important aspects in terms of biological similarity. Herein, a novel similarity searching approach using a Bayesian inference network is discussed. Similarity searching is regarded as an inference or evidential reasoning process in which the probability that a given compound has biological similarity with the query is estimated and used as evidence.

\n An inference network model for molecular similarity searching: The similarity search problem is modeled using inference or evidential reasoning under uncertainty. The inference network model treats similarity searching as an evidential reasoning process in which multiple sources of evidence about compounds and reference structures are combined to estimate resemblance probabilities.Many methods have been developed to capture the biological similarity between two compounds for use in drug discovery. A variety of similarity metrics have been introduced, the Tanimoto coefficient being the most prominent. Many of the approaches assume that molecular features or descriptors that do not relate to the biological activity carry the same weight as the important aspects in terms of biological similarity. Herein, a novel similarity searching approach using a Bayesian inference network is discussed. Similarity searching is regarded as an inference or evidential reasoning process in which the probability that a given compound has biological similarity with the query is estimated and used as evidence. Our experiments demonstrate that the similarity approach based on Bayesian inference networks is likely to outperform the Tanimoto similarity search and offer a promising alternative to existing similarity search approaches.\n

The inability to satisfactorily model parameters as a function of distance from farms demonstrated the complexity of their spatial distribution and highlighted the need to improve our understanding of farm footprints to avoid detrimental environmental effects as a consequence of culture intensification. The BN approach successfully identified reliable monitoring parameters based on reviewed impact studies and has potential to support cost-effective monitoring. For use at specific farms, site-specific data should be integrated into the BN and additional variables could easily be added. BNs enable the synthesis of scientific and industry research data, practical experience and stakeholders’ perspectives, which are important in the development of monitoring guidelines that meet the needs of all parties.\n
