In this paper we propose a Round Trip Translation (RTT) based approach to sentence-level confidence estimation (CE) for spoken language translation without the assistant of reference translations generated by human. A number of novel RTT based features are introduced to reflect the quality of spoken language translation in more detail. After combing various kinds of features together, support vector...
This paper presents experiments using several vector space models in Automated Essay Scoring (AES). Firstly, we compare four different Vector Space Models (VSM) which are the Word-based Vector Space Model (W-VSM), the Weight Adapted Word-based Vector Space Model (WAW-VSM), the Latent Semantic-based Vector Space Model (LS-VSM) and the Sequence Latent Semantic-based Vector Space Model (SLS-VSM). The...
Avatars are virtual characters making the communication between user and machine more natural and interactive. The main advantage of using avatars within interfaces is to allow user to interact intuitively with the system by giving him the illusion of communicating with a real human. This illusion is obtained by mimicking human communication, i.e. giving avatar the ability of expressing emotions through...
This paper dissects the basic characters of family firm gene in china by use of the corporate gene theory, and analyses the main problem which exist in family firm gene. To proceed from the genetic gene of Chinese family firm, we emphasize on analyzing which gene is needed by a successful family firm. The relevant analysis indicated that genetic change and negative corporate gene resulted from the...
This paper presents a new approach that uses linguistic knowledge and pronunciation space for automatic detection of typical phone-level errors made by non-native speakers of mandarin. Firstly, linguistic knowledge of common learner mistakes is embedded in the calculation of log-posterior probability and the revised log-posterior probability (RLPP) is regarded as the measure of mispronunciation; secondly,...
It is described in this paper for the application of pitch/tone information in the parametric trajectory model. Pitch as a dynamic feature and its contours—tone as a segmental-level feature are deserved their own particular characteristics, which match case of parametric trajectory model better compared with MFCC and energy. Here we give an improved pitch extraction algorithm and especially the “total”...
