“I have known Ivan since 2011. He was employed in SRG-IT company as a mathematician for about half a year. During his tenure of employment Ivan revealed his ability in deeply understanding of new subjects and applying his knowledge in practice. He developed mathematical models for automatic real estate valuation. The models dramatically increased precision and predictability of our system/ Ivan did a very good job in our company and I can describe him as a well-motivated, talented, extraordinary and hard-working person, who has outstanding communication and organization skills.”

Crawling policies based on web page popularity prediction
ECIR'2014
In this paper, we focus on crawling strategies for newly discovered URLs. Since it is impossible to crawl all the new pages right after they appear, the most important (or popular) pages should be crawled with a higher priority. One natural measure of page importance is the number of user visits. However, the popularity of newly discovered URLs cannot be known in advance, and therefore should be predicted relying on URLs’ features. In this paper, we evaluate several methods for predicting new…
In this paper, we focus on crawling strategies for newly discovered URLs. Since it is impossible to crawl all the new pages right after they appear, the most important (or popular) pages should be crawled with a higher priority. One natural measure of page importance is the number of user visits. However, the popularity of newly discovered URLs cannot be known in advance, and therefore should be predicted relying on URLs’ features. In this paper, we evaluate several methods for predicting new page popularity against previously investigated crawler performance measurements, and propose a novel measurement setup aiming to evaluate crawler performance more realistically. In particular, we compare short-term and long-term popularity of new ephemeral URLs by estimating the rate of popularity decay. Our experiments show that the information about popularity decay can be effectively used for optimizing ordering policies of crawlers, but further research is required to predict it accurately enough.
