Semantic chunking
… such as sentence simplification or shallow chunking. The main contribution of this thesis is the introduction of the task of semantic chunking as a general approach to reducing the cost of processing long sentences. The goal of semantic chunking is to find semantically contained fragments of …

Computational chunking in Chess
… search” (Gobet and Simon 1998). The effects of chunking in chess are widely reported in the literature, however papers reporting the nature of chunks are largely based on inference from psychological experimentation. This thesis reports original work resulting from extensive data mining of a …

Data Chunking in Quasi-synchronous DS-CDMA
… DS-CDMA reverse link using the method of “data chunking”. The basic premise is derived by making a link between TDMA and synchronous DS-CDMA. By considering some basic TDMA limitations, a proposed “data chunked” quasi-synchronous DS-CDMA system is derived from a TDMA system. The effects of such …

Application of chunking to the design of complex information displays
Chunking is defined as the process of organizing information into multi-item clusters appropriate to solving a particular task. It was hypothesized that dynamic information displays could be formatted to group related items. This formatting would facilitate chunking and, in turn, serve to reduce …

Chunking: Intervention designed to relieve and improve reading performance among dyslexic student
… is most prominent when reading a crowded text. “Chunking” is an intervention where extra spaces are added as visual cues in between morphemes and other units in words, within a reading text, with the aim of reducing visual interference. The aim of this study was to test if a chunking intervention …

Improving learner reaction, learning score, and knowledge retention through the chunking process in corporate training.
… study was to investigate the application of the chunking process to the design and delivery of workforce training. Students in a 1-hour course (N = 110) were measured on learner reaction, learning score achievement, and knowledge retention to see whether or not chunking training in a 1-hour …

Syllables and the M Language : improving unknown word guessing
… for word decomposition called "probabilistic chunking," which achieves a 70% success rate in word syllabification and has potential applications in automatically decomposing words into morphemes. I also create algorithms which use probabilistic chunking to syllabify unknown words and thereby …

Strategy Uses and Study Time: Relationship with Memory Performance in Older Adults
… participants to the simple mnemonic strategy of chunking and by allowing two different study times, it was hypothesized that recall would be higher for the groups instructed to use the chunking than for the no-strategy group. It was also hypothesized that the group given the longer study time …

Distributed Support Vector Machine Learning
… implementations must contend with some kind of chunking process to train parts of the data at a time (10 chunks of 1000, for example, to learn the 10,000). Sequential and multi-threaded chunking methods provide a way to run the SVM on large datasets while retaining accuracy. The multi-threaded …

An efficient data deduplication design with flash-memory based solid state drive.
… objective, this dissertation proposes a novel chunking algorithm that breaks the input dataset into chunks, with a higher redundancy or with larger sizes, so as to identify the more duplicated data without producing larger numbers of chunks, as compared to other chunking algorithms. To achieve …

Improving the performance of hierarchical hidden Markov models on information extraction tasks
… extraction tasks of Reference Tagging and Text Chunking. In both tasks, MSHHMMs show consistently good performance across varying sizes of training data. In the case of Reference Tagging, the accuracy of the MSHHMM is comparable to other methods. However, when the volume of training data is …

Representational redescription and the development of cognitive flexibility
… by a limited cognitive capacity, the level of 'chunking' in a domain and the possession of an overview of the relevant conceptual space. Chunking is achieved through a re-representation of behaviour and the environment, rather than a direct operation on representations. The BAIRN system …

An Efficient Storage And Retrieval Mechanism For Large Unstructured Grids
… and in the data file on disk using a specialized chunking approach that maintains the spatial neighborhood relationships inherent in the unstructured grid. This reorganization produces significant gains in performance by reducing the number of accesses made to the data file. We examine the effects …

How Students Explain Their Word-Solving Strategies When They Come to a Word They Don’t Know While Reading and How Does That Explanation Change When Students Are Explicitly Taught a Variety of Reading Strategies
… did not use the strategies of sounding out and chunking that they said they used, but used the strategies of rereading and self-correction while they read.

An analysis of pattern usage in CS1 courses
… at higher levels of abstraction, mentally ""chunking"" groups of lines of code into a single abstraction. These chunks have been referred to as patterns in CS1 literature and pattern-oriented instruction has been proposed. This thesis builds on the existing literature by analyzing instructor …
