Estimating Page Importance based on Page Accessing Frequency

by Komal Sachdeva, Ashutosh Dixit , 2014
"... With the vast growth of the Internet, many web pages are available online. Search engines use a component called as web crawlers for collecting these web pages from the web for storage and indexing. Many web pages are autonomous and are updated independent of the users..As the web pages are updated ..."

autonomously; users do not come to know of how often the sources change. An incremental crawler visits the web repeatedly after a specific interval of time for the updation of its collection. Users are benefited by knowing the page importance based upon the page accessing frequency. This paper finds out

Page Relevance based on Page Accessing Frequency

Amortized Efficiency of List Update and Paging Rules

by Daniel D. Sleator, Robert E. Tarjan , 1985
"... In this article we study the amortized efficiency of the “move-to-front” and similar rules for dynamically maintaining a linear list. Under the assumption that accessing the ith element from the front of the list takes 0(i) time, we show that move-to-front is within a constant factor of optimum amo ..."

among a wide class of list maintenance rules. Other natural heuristics, such as the transpose and frequency count rules, da not share this property. We generalize our results to show that move-to-front is within a constant factor of optimum as long as the access cost is a convex function. We also study

Data Preparation for Mining World Wide Web Browsing Patterns

by Robert Cooley, Bamshad Mobasher, Jaideep Srivastava - KNOWLEDGE AND INFORMATION SYSTEMS , 1999
"... The World Wide Web (WWW) continues to grow at an astounding rate in both the sheer volume of tra#c and the size and complexity of Web sites. The complexity of tasks such as Web site design, Web server design, and of simply navigating through a Web site have increased along with this growth. An i ..."

. An important input to these design tasks is the analysis of how a Web site is being used. Usage analysis includes straightforward statistics, such as page access frequency, as well as more sophisticated forms of analysis, such as finding the common traversal paths through a Web site.

M-tree: An Efficient Access Method for Similarity Search in Metric Spaces

by Paolo Ciaccia, Marco Patella, Pavel Zezula , 1997
"... A new access meth d, called M-tree, is proposed to organize and search large data sets from a generic "metric space", i.e. whE4 object proximity is only defined by a distance function satisfyingth positivity, symmetry, and triangle inequality postulates. We detail algorith[ for insertion o ..."

Packet Switching In Radio Channels: Part III -- Polling and . . .

by Fouad A. Tobagi, Leonard Kleinrock - IEEE TRANSACTIONS ON COMMUNICATIONS , 1976
"... Here we continue the analytic study of packet switching in radio channels which we reported upon in our two previous papers [ 11, [2]. Again we consider a population of terminals communicating with a central station over a packet-switched radio channel. The allocation of bandwidth among the contend ..."

the contending terminals can befixed [e.g., time-division multiple access (TDMA) or frequency-division multiple access (FDMA)]-,rundom [e.&, ALOHA or carrier sen? multiple access (CSMA)] or centrally controlled (e.g., polling or reservation). In this paper we show that with a large population of bursty users

Representing twentieth century space-time climate variability, part 1: development of a 1961-90 mean monthly terrestrial climatology

"... The construction of a 0.58 lat 3 0.58 long surface climatology of global land areas, excluding Antarctica, is described. The climatology represents the period 1961–90 and comprises a suite of nine variables: precipitation, wet-day frequency, mean temperature, diurnal temperature range, vapor pressur ..."
