    A Western-Blot to Detect Antibody to Avian Reovirus

    No full text
    Purified reoviruses RAM‐1 and 74/2 were combined and used as antigen. The Western blot detected antibodies to 16/16 avian reoviruses in sera from experimentally inoculated chickens, and to 6/7 reoviruses in contact sera from naturally infected chickens. The test was specific for avian reovirus and was more sensitive and specific than immunofluorescence

    PrOntoLearn: Unsupervised Lexico-Semantic Ontology Generation using Probabilistic Methods

    Abstract. Formalizing an ontology for a domain manually is well-known as a tedious and cumbersome process. It is constrained by the knowledge acquisition bottleneck. Therefore, researchers developed algorithms and systems that can help to automatize the process. Among them are systems that include text corpora for the acquisition. Our idea is also based on vast amount of text corpora. Here, we provide a novel unsupervised bottom-up ontology generation method. It is based on lexico-semantic structures and Bayesian reasoning to expedite the ontology generation process. We provide a quantitative and two qualitative results illustrating our approach using a high throughput screening assay corpus and two custom text corpora. This process could also provide evidence for domain experts to build ontologies based on top-down approaches
