Probability Theory Predicts That Chunking into Groups of Three or Four Items Increases the Short-Term Memory Capacity 被引量:1

Short-term memory allows individuals to recall stimuli, such as numbers or words, for several seconds to several minutes without rehearsal. Although the capacity of short-term memory is considered to be 7 &#177?2 items, this can be increased through a process called chunking. For example, in Japan, 11-digit cellular phone numbers and 10-digit toll free numbers are chunked into three groups of three or four digits: 090-XXXX-XXXX and 0120-XXX-XXX, respectively. We use probability theory to predict that the most effective chunking involves groups of three or four items, such as in phone numbers. However, a 16-digit credit card number exceeds the capacity of short-term memory, even when chunked into groups of four digits, such as XXXX-XXXX-XXXX-XXXX. Based on these data, 16-digit credit card numbers should be sufficient for security purposes. 展开更多

They are easy to be browsed, but difficult to be understood by computer. Chunk parsing and entity relation extracting is important work to understanding information semantic in natural language processing. Chunk analysis is a shallow parsing method, and entity relation extraction is used in establishing relationship between entities. Because full syntax parsing is complexity in Chinese text understanding, many researchers is more interesting in chunk analysis and relation extraction. Conditional random fields (CRFs) model is the valid probabilistic model to segment and label sequence data. This paper models chunk and entity relation problems in Chinese text. By transforming them into label solution we can use CRFs to realize the chunk analysis and entities relation extraction. 展开更多

English language skill is an important part of the comprehensive linguistic competence for college students.Especiallythe language output competence by students Autonomous Learning.During the 70 s of the last century,Becker came up with theterm and and later put forward his Lexical Chunks.Since then,it has been researched increasingly and paid more and more atten-tion to due to the fact that lexical chunks possess the features of both vocabulary and grammar.Teachers should exert lexicalchunks approach,consciously raise students' awareness of lexical chunks,and design various instructional activities based on dif-ferent teaching contents to improve students' language output competence.In this paper,the author carries out an experiment onthe college students from two classes of the same level in Grade one.And compared with the experimental class itself or with thecontrol class,found the students in experimental class have made far greater progress in English speaking and writing. 展开更多
