The Web today includes many pages intended to deceive search engines, in which content or links are created to attain an unwarranted result ranking. Since the links among web pages are used to calculate authority, ranking systems should take into consideration which pages contain content to be trusted and which do not. In this paper, we assume the existence of a mechanism, such as, but not limi...

In this paper, we reflect on the design, development, and deployment of G-nome Surfer; a multi-touch tabletop user interface for collaborative exploration of genomic data. G-nome Surfer lowers the threshold for using advanced bioinformatics tools, reduces the mental workload associated with manipulating genomic information, and fosters effective collaboration. We describe our two-year-long effo...

PageRank is the algorithm used by the Google search engine for ranking web pages. PageRank Algorithm calculates for each page a relative importance score which can be interpreted as the frequency of how often a page is visited by a surfer. The purpose of this work is to provide a mathematical analysis of the PageRank Algorithm. We analyze the random surfer model and the linear algebra behind it...

The Tucuruí Hydro-Power Complex reservoir, Pará State, Amazon Region-Brazil, as well other reservoirs is subject to natural alterations and anthropogenic activities which in turn affect the environmental balance. aim of this work was verify if geostatistical models can be used spatial-temporal evaluation water quality reservoirs. Surfer 13® software interpolate spatial distribution data, two ye...

The measurement and control of soil moisture are the key technologies of precision agriculture. In order to real-time detect soil moisture content faster and more accurately, a portable soil moisture sensor based on NIR spectroscopy was developed. With the sixty soil samples collected from a winter jujube orchard, a linear regression model was established. The determination coefficients of the ...

The PageRank algorithm is an iterative algorithm used in the Google search engine to improve the results of requests by taking into account the link structure of the web. More interesting and intelligent surfer model combining the link and content information in PageRank have been proposed in the literature. The main disadvantage of those models is that the combination of single word PageRank t...

In this paper we provide theoretical and experimental results on a random-surfer model for construction of a random graph. In this model, a new node connects to the existing graph by choosing a start node uniformly at random and then performing a short random walk. We show that in certain formulations, this results in the same distribution as the preferential-attachment random-graph model, and ...

We propose Focused Page Rank (FPR) algorithm adaptation for the problem of scientific papers ranking. FPR is based on the Focused Surfer model, where the probability to follow the reference in a paper is proportional to its citation count. Evaluation on Citeseer autonomous digital library content showed that proposed model is a tradeoff between traditional citation count and basic Page Rank (PR...

The PageRank algorithm, used in the Google search engine, greatly improves the results of Web search by taking into account the link structure of the Web. PageRank assigns to a page a score proportional to the number of times a random surfer would visit that page, if it surfed indefinitely from page to page, following all outlinks from a page with equal probability. We propose to improve PageRa...

PageRank is a way to rank Web pages taking into account hyper-link structure of the Web. PageRank provides efficient and simple method to find out ranking of Web pages exploiting hyper-link structure of the Web. However, it produces just an approximation of the ranking since the random surfer model uses just uniform distributions for all situation of choice happening during the surf process. In...
