Research on Domain Self‐Aadaptation of Chinese‐English EBMT
Hongfei Jiang,Muyun Yang,Tiejun Zhao 한국어정보학회 2006 한국어정보학 Vol.8 No.1
The example‐based machine translation system in the specific domain can be developed in a short time with a high translation quality. Though an EBMT system can be transplanted to a new domain quickly, when faces to the need for the multi‐doamins translation, its advantage in domain adaptability will be affected. In order to solve this problem a new domain sensative EBMT translation model is proposed. Through combining the text‐classsify technique, the proposed EBMT will judge the input text and then select the most appropriate example base for the following translations. The experiments showed that this method can improve the performance of the EBMT system and meet the need for Olympicsoriented multi‐domains translations in some extents

Two strains of porcine reproductive and respiratory syndrome virus (PRRSV) were isolated in 2006 and 2016 and designated as FZ06A and FZ16A, respectively. Inoculation experiments showed that FZ06A caused 100% morbidity and 60% mortality, while FZ16A caused 100% morbidity without death. By using genomic sequence and phylogenetic analyses, close relationships between a Chinese highly pathogenic PRRSV strain and the FZ06A and FZ16A strains were observed. Based on the achieved results, multiple genomic variations in Nsp2, a unique N-glycosylation site (N33→K33), and a K151 amino acid (AA) substitution for virulence in the GP5 of FZ16A were detected; except the 30 AA deletion in the Nsp2-coding region. Inoculation experiments were conducted and weaker virulence of FZ16A than FZ06A was observed. Based on our results, a 30 AA deletion in the Nsp2-coding region is an unreliable genomic indicator of a high virulence PRRSV strain. The Nsp2 and GP5 differences, in addition to the virulence difference between these two highly pathogenic PRRSV strains, have the potential to be used to establish a basis for further study of PRRSV virulence determinants and to provide data useful in the development of vaccines against this economically devastating disease.
