A tocharian B parallel to the legend of kalmāṣapāda and sutasoma of the old uyghurdaśakarmapathāvadānamālā

According to the colophons of the Old Uyghur Daśakarmapathāvadānamālā (DKPAM), this collection of Buddhist birth legends was translated from a Tocharian A (tohrı) source which in turn was based on a Tocharian B (küsän) original. A Tocharian B fragment from the Paris Pelliot collection presents a close parallel to the legend of Kalmāṣapāda and Sutasoma of the Old Uyghur DKPAM. This legend is so far not attested in Tocharian A. Although the existence of a Tocharian A intermediary text cannot be excluded, the parallel is so close that the Old Uyghur text may also have been translated directly from Tocharian B.

Phrase based Uyghur language text categorization

Text representation is the most important phase in automatic text categorization.In the Vector Space Model(VSM) based text representation,the selection of feature granularity has the direct impact on the text categorization performance.The statistical approach based Uyghur phrase extraction algorithm was proposed and the Uyghur text categorization experiments was conducted using Support Vector Machine(SVM) algorithm based on the extracted phrases as text features.The experimental results show that the phrase based Uyghur text categorization achieves higher classification precision and recall compared to the word based categorization.

Improved suffix tree clustering for Uyghur text

In order to solve the problems of non-standard,repetition and redundancy of information in the process of selecting the base class phrases,an improved Suffix Tree Clustering(STC) method was proposed.Firstly,phrase mutual information algorithm was put forward to choose the base class phrases abiding by Uyghur grammar.Secondly,in order to reduce the repeated base class phrase,the phrase reduction algorithm based on Uyghur grammar was proposed.Thirdly,on the basis of the first two steps,the phrase redundancy algorithm based on Uyghur grammar was constructed to remove redundant phrase.The experimental results show that this method improves the recall and the precision compared with STC.This indicates that the improved algorithm can enhance clustering performance effectively.

An Old Uyghur fragment of the Lotus Sūtra from the Krotkov collection in St. Petersburg

This paper presents an edition of a newly identified Old Uyghur fragment of the Lotus Sūtra from the Krotkov collection in the Institute of Oriental Manuscripts of the Russian Academy of Sciences. The text mainly explains the merit of preaching, reciting and hearing the Lotus Sūtra through three parables, claiming that the text is from the nom cacaki sudur ‘Law-Flower-Sūtra’, the Old Uyghur title of the Lotus Sūtra. However, there is no identical passage in the known Chinese translations of the Lotus Sūtra. Presumably, the Old Uyghur text is a unique composition by Uyghurs, though one cannot exclude the possibility that the Old Uyghur text might also be a translation of an unknown Chinese text of similar content.
