Short Text Segmentation for Improved Query Processing

Text Pre-processing and Text Segmentation for OCR

Optical Character Recognition (OCR) systems have been effectively developed for the recognition of printed script. The accuracy of OCR system mainly depends on the text preprocessing and segmentation algorithm being used. When the document is scanned it can be placed in any arbitrary angle which would appear on the computer monitor at the same angle. This paper addresses the algorithm for corre...

Image Segmentation using Improved Imperialist Competitive Algorithm and a Simple Post-processing

Image segmentation is a fundamental step in many of image processing applications. In most cases the image’s pixels are clustered only based on the pixels’ intensity or color information and neither spatial nor neighborhood information of pixels is used in the clustering process. Considering the importance of including spatial information of pixels which improves the quality of image segmentati...

Intra-query Concurrent Pipelined Processing for Distributed Full-Text Retrieval

Pipelined query processing over a term-wise distributed inverted index has superior throughput at high query multiprogramming levels. However, due to long query latencies this approach is inefficient at lower levels. In this paper we explore two types of intra-query parallelism within the pipelined approach, parallel execution of a query on different nodes and concurrent execution on the same n...
