Abstract This paper focuses on retrieval of web documents with improved response time and similarity using particle swarm optimization (PSO) technique. Since the nature of the web data is distributed, volatile and uncertain, an accurate and speedy access is required. Hence a novel approach on evolutionary bio-inspired Swarm Intelligence techniques to optimize search process in Web Information Retrieval systems is proposed and developed. Here,... This paper focuses on retrieval of web documents with improved response time and similarity using particle swarm optimization (PSO) technique. Since the nature of the web data is distributed, volatile and uncertain, an accurate and speedy access is required. Hence a novel approach on evolutionary bio-inspired Swarm Intelligence techniques to optimize search process in Web Information Retrieval systems is proposed and developed. Here, we propose a novel algorithm using basic PSO technique which works on both small CACM and huge RCV1 collections. We apply this on the pre-processed documents to retrieve most similar documents with a very less response time. This paper also reveals a comparative study with the existing method.

Fundamental approach to literature metrology were introduced in this paper to make a statistical analysis on the thesis of library and information science during the period of the 11th Five-Year Plan of China with academic focus on CNKI, CSSCI collections, citation frequency, productive authors and authorities. With academic defects and deficiencies summarized from the statistical study, this paper aimed at making recommendations and references for the disciplinary development planning of library and information science, faculty construction and talent cultivation, as well as relative researching concerns.

Abstract This survey paper presents a comprehensive study of Urdu Optical Character Recognition (OCR) methodologies. The main focus of the study is detail investigation of the techniques used to recognize the Nastaliq, Naskh and other similar scripts fonts. These script fonts are used to write Urdu, Arabic, Pashto and Sindhi etc. languages. Several methods of text recognition and classification of Urdu like cursive scripts... This survey paper presents a comprehensive study of Urdu Optical Character Recognition (OCR) methodologies. The main focus of the study is detail investigation of the techniques used to recognize the Nastaliq, Naskh and other similar scripts fonts. These script fonts are used to write Urdu, Arabic, Pashto and Sindhi etc. languages. Several methods of text recognition and classification of Urdu like cursive scripts are discussed. The survey contains the comparison and description of each method in a brief way which identifies handwritten, printed and online text recognition as well. For each optical character recognition (OCR) the phases of pre-processing, segmentation, feature extraction, classification and finally recognition are discussed. After the comprehensive analysis of all methodologies critics and future work in Urdu cursive scripts, i.e. Naskh and Nastaliq scripts are also proposed. Read More Read Less
