DATA COMPRESSION USING EFFICIENT DICTIONARY SELECTION METHOD

A Modified Compression Technique for Trace Data Using Dictionary Method

In VLSI design circuits, System-On-Chip consumes more area due to huge data volume in the hardware. In order to reduce that constraint, the size of the trace buffer should be maintained constant. The trace data should be compressed to acquire huge amount of data. To compress those data several conventional techniques has been followed. Here in the proposed system, an approach called Look-Up-Tab...

Data Compression Using a Dictionary of Patterns

Most modern lossless data compression techniques used today, are based in dictionaries. If some string of data being compressed matches a portion previously seen, then such string is included in the dictionary and its reference is included every time it occurs. A possible generalization of this scheme is to consider not only strings made of consecutive symbols, but more general patterns with ga...

Sentiment Analysis of Social Networking Data Using Categorized Dictionary

Sentiment analysis is the process of analyzing a person’s perception or belief about a particular subject matter. However, finding correct opinion or interest from multi-facet sentiment data is a tedious task. In this paper, a method to improve the sentiment accuracy by utilizing the concept of categorized dictionary for sentiment classification and analysis is proposed.  A categorized dictiona...

FPGA Based Data Compression using Dictionary based LZW Algorithm

Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of algorithms in different compression methods applications. In a distributed environment, large data files remain a major bottleneck. Compression is an important component of the solutions available for creating file sizes of manageable and transmittable dimensions. When high-speed media or channe...
