    Using a Probabilistic Class-Based Lexicon for Lexical Ambiguity Resolution

    Full text link
    This paper presents the use of probabilistic class-based lexica for disambiguation in target-word selection. Our method employs minimal but precise contextual information for disambiguation. That is, only information provided by the target-verb, enriched by the condensed information of a probabilistic class-based lexicon, is used. Induction of classes and fine-tuning to verbal arguments is done in an unsupervised manner by EM-based clustering techniques. The method shows promising results in an evaluation on real-world translations.Comment: 7 pages, uses colacl.st

    Inducing a Semantically Annotated Lexicon via EM-Based Clustering

    Full text link
    We present a technique for automatic induction of slot annotations for subcategorization frames, based on induction of hidden classes in the EM framework of statistical estimation. The models are empirically evalutated by a general decision test. Induction of slot labeling for subcategorization frames is accomplished by a further application of EM, and applied experimentally on frame observations derived from parsing large corpora. We outline an interpretation of the learned representations as theoretical-linguistic decompositional lexical entries.Comment: 8 pages, uses colacl.sty.

    This study examines the plant species distribution and cover abundance scales relations with soil and other environmental factors such as elevation, exposure, slope in the alpine region. 10 sample areas were determined for experimental field study in the alpine region. Plant species and their cover abundance scales and 0-5 and 5-15cm soil depth analysis were conducted in the field study. C, N, pH, soil salinity, soil texture, C/N and CaCO3 (%) were determined in soil laboratory analysis. To examine the effect of land use by the local people; sample areas were determined both on used area and non-used area in the alpine region.publisher versio

    Evidence of climate change, resource shortages and biodiversity loss is growing in significance every year. This second edition of Environmental Policy explains how policy can resond and bring about greater sustainability in individual lifestyles, corporate strategies, national policies and international relations. The book discusses the interaction between environmental and human systems, suggesting environmental policy as a way to steer human systems to function within environmental constraints

    Aetiology of Ludwig van Beethoven’s hearing impairment: hypotheses over the past 100 years – A systematic review

    No full text
    Objectives!#!Even 250 years after Beethoven's birth, the irrevocable cause of his hearing impairment remains unclear despite multiple publications by different professional groups. This study aimed to analyse the development of the most likely aetiologies during the last 100 years by a systematic review of the relevant medical literature.!##!Methods!#!A systematic review of medical literature in PubMed!##!Results!#!48 publications were included. The following aetiologies were supposed: otosclerosis (n = 10), syphilis (n = 9), Paget's disease (n = 6), neural deafness (n = 5), immunopathy with inflammatory bowel disease, neural deafness with otosclerosis, sarcoidosis or lead intoxication (n = 2), and systemic lupus erythematosus, trauma, labyrinthitis or inner ear disease (n = 1). There is an ongoing effort with a mean publication frequency in this topic of 0.48/year. From 1920 to 1970, otolaryngologists were the group with the highest interest in this field (67%), whereas since 1971 most authors have belonged to non-otolaryngologic subspecialities (81%).!##!Conclusion!#!Over the past 100 years, otosclerosis and syphilis were predominantly supposed to be the underlying causes. The hypothesis of syphilis-although rejected for a long time-has had a remarkable revival during the past 20 years. Regarding the outcome following therapeutic intervention by cochlear implantation, the differential diagnosis of neural deafness would be relevant today
