The natural language processing (NLP) of sign language aims to make human sign language “understandable” to computers. In achieving this goal, the text of sign language should first be segmented into sign sequences for computers to recognize. This segmentation process constitutes the basis for the information processing of sign language. With an aim to solve the problems in expressing Chinese sign...
Sequence alignment is an important method of sequence analysis in biological informatics, by which the characteristics of a gene family can be conveniently determined through consensus sequence. Finding a consensus sequence prior to multiple sequence alignment makes the sequence alignment easier. Thus, the consensus sequence should be produced by simulated annealing and star alignment algorithms....
Data warehouses are used to store large quantities of materialized views to accelerate OLAP server response to query. The method to efficiently and accurately return the correct results at materialized view in a limited storage space is an important question that is being emphasized and a recognized difficulty for the ROLAP server design. This paper presents an improved and effective algorithm for...
The investigation on sentence processing has been the focus of language psychologists. The factors that affect sentence processing continue to be explored. However, Chinese Sign Language (CSL), which is a natural language for the deaf community, has not been analyzed on whether similar processing mechanisms underlie the procession of sentences of the spoken language. We examined the electrophysiological...
After a systematic review on psychological and neurophysiological studies, we propose a computational cognitive model for Chinese Sign Language (CSL) perception and comprehension with detailed algorithmic descriptions based on cognitive functionalities in human language processing. A semantic neural network based on this model is introduced as the knowledge representation method in CSL comprehension...
Spoken language contrasts to the written language that provides more prosodic features. There is variety of research about pitch accent in different language. But the less attention is paid to the auditory pitch accent processing and representation of the bilinguals. In the present study, the event-related potentials (ERPs) are used to investigate how Uyghur bilinguals represent and process pitch...
Sign recognition has evolved from traditional video-based to 3D-based image recognition. Most documents are presented with Kinect-based somatosensory terminals, which are limited by difficulties in precisely describing the motions performed by various palm joints. The linguistic details of sign language (SL), such as position, direction, and movement, therefore have to be manually inputted. Meanwhile,...
