  1. 1. Development of economic forest tree breeding objectives

    Detta är en avhandling från ; Dept. of Plant Biology and Forest Genetics, Swedish University of Agricultural Sciences

    Författare :Mats Berlin; Sveriges lantbruksuniversitet.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The overall objective of this thesis was to suggest a framework for developing forest tree breeding objectives with particular emphasis on boreal conditions and, as components of this framework, to define breeding objectives and calculate economic weights based on two case studies of Scots pine in northern Sweden. The framework was designed to take into account boreal conditions, with long rotations, heterogeneous raw materials and a diverse production system. LÄS MER

  4. 4. The Multilingual Forest Investigating High-quality Parallel Corpus Development

    Detta är en avhandling från Stockholm : Department of Linguistics, Stockholm University

    Författare :Yvonne Adesam; Martin Volk; Joakim Nivre; Koenraad de Smedt; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; treebank; syntax; alignment; corpus; annotation projection; multilingual; tagging; parsing; datorlingvistik; Computational Linguistics;

    Sammanfattning : This thesis explores the development of parallel treebanks, collections of language data consisting of texts and their translations, with syntactic annotation and alignment, linking words, phrases, and sentences to show translation equivalence. We describe the semi-manual annotation of the SMULTRON parallel treebank, consisting of 1,000 sentences in English, German and Swedish. LÄS MER
