محسن طالب خواهد گفت: در این ارائه سعی خواهد شد تا پس از بررسی تاریخچه مختصری از سرویس های مبتنی بر نقشه در ایران و جهان، به بسترهای فنی و اطلاعاتی لازم برای پیاده سازی این گونه سرویس ها اشاره شده و نمونه هایی از کاربردهای آن در نسل بعدی نرم افزارهای مکان محور ذکر شود.
این ارائه برای اولین همایش آینده طراحی وب طراحی و ارائه گردیده است.

The document discusses the role of text mining in search engines. It describes how search engines work by crawling websites and indexing key terms. Text mining can help search engines provide more relevant and contextualized search results through techniques like clustering, categorization, and entity extraction. The document also discusses future trends in search engines leveraging more advanced text mining techniques like summarization and answering intelligent questions.
This document provides an overview of distributed web-based systems, including the key components and technologies that enable them. It discusses the World Wide Web and how documents are accessed via URLs. It also describes HTTP and how connections and requests/responses work. Other topics covered include caching, content distribution networks, web services, traditional and multi-tiered web architectures, web server clusters, and web security protocols like SSL.

First, let us assume that when a node wants to join it
contacts an arbitrary other node, possibly from a list of
well-known access points.
This access point is just a regular member of the overlay,
except that we can assume it to be highly available.
In this case, it turns out that protocols that use only push
mode or only pull mode can fairly easily lead to
disconnected overlays.
In other words, groups of nodes will become isolated and
will never be able to reach every other node in the
network.
Clearly, this is an undesirable feature, for which reason it
makes more sense to let nodes actually exchange entries.
