Today, web plays a critical role in human life and also simplifies the same to a great extent. However, due to the towering increase in the number of web pages, the challenge of providing quality and relevant information to the users also needs to be addressed. Thus, search engines need to implement such algorithms which spans the pages as per user's interest and satisfaction and rank them...
Text retrieval systems store a great variety of documents, from abstracts, newspaper articles, and web pages to journal articles, books, court transcripts, and legislation. Collections of diverse types of documents expose shortcomings in current approaches to ranking. Use of short fragments of documents, called passages, instead of whole documents can overcome these shortcomings: passage rankin...
Metrology, the science of measurement, is very important in the development of science and engineering principles if any meaningful progress will be made in these fields. This concept also applies to computer security if decision makers are to rely on judgment based on metrics. Management needs to establish how secured their organizations are, the amount of resources to allocate to various comp...
This paper presents a study on personalized add-on filters applied to web search results in order to make those results more intuitive to users. Fuzzy Sets and Logic are used in order to construct such filters. Linguistic features are extracted as their universe of discourse. Three experimental filters are presented in the following specific contexts: (1) narrowing down results, (2) product spe...
We discuss some simple theoretical properties of web page ranking distributions, including PageRank (Brin and Page, 1998), which are based on uniformly ergodic Markov chains. We also propose a modification of PageRank whith reduces the bias for older documents, and discuss details of our simulation programs.
We modify the Google Page-Rank algorithm, which is primarily used for ranking web pages, to analyze the gene reachability in complex gene co-expression networks. Our modification is based on the average connections per gene. We propose a new method to compute the metric of average connections per gene, inspired by the PageRank algorithm. We calculate this average as eight for human genome data ...
This paper gives an introduction to Web mining, then describes Web Structure mining in detail, and explores the data structure used by the Web. This paper also explores different Page Rank algorithms and compare those algorithms used for Information Retrieval. In Web Mining, the basics of Web mining and the Web mining categories are explained. Different Page Rank based algorithms like PageRank ...
This year, the IR group of ICT participated in the terabyte track named-page Finding subtask for the first time. Since the document collection is as large as about 426G, our most important goal is to find an efficient way to catch the target web page in such a huge size data set. Meanwhile we want to make the indexing and retrieval processing at a reasonable low cost, both on hardware and time-...
This paper presents a methodology for the ontology based semantic annotation of web pages with annotation weighting scheme that takes advantage of the different relevance of structured document fields. The retrieval model is based on the importance factors of the structural elements, which are used to re-rank the documents retrieval by the ontology based distance measure. The relevance concept ...
Traditional search engines on World Wide Web (WWW) focus essentially on relevance ranking at the page level. But this lead to missing innumerable structured information about real-world objects embedded in static Web pages and online Web databases. Page-level information retrieval (IR) can unfortunately lead to highly inaccurate relevance ranking in answering object-oriented queries. On the oth...
