TL;DR: A new hypertext resource discovery system called a Focused Crawler that is robust against large perturbations in the starting set of URLs, and capable of exploring out and discovering valuable resources that are dozens of links away from the start set, while carefully pruning the millions of pages that may lie within this same radius.
Abstract: The rapid growth of the World-Wide Web poses unprecedented scaling challenges for general-purpose crawlers and search engines In this paper we describe a new hypertext resource discovery system called a Focused Crawler The goal of a focused crawler is to selectively seek out pages that are relevant to a pre-defined set of topics The topics are specified not using keywords, but using exemplary documents Rather than collecting and indexing all accessible Web documents to be able to answer all possible ad-hoc queries, a focused crawler analyzes its crawl boundary to find the links that are likely to be most relevant for the crawl, and avoids irrelevant regions of the Web This leads to significant savings in hardware and network resources, and helps keep the crawl more up-to-date To achieve such goal-directed crawling, we designed two hypertext mining programs that guide our crawler: a classifier that evaluates the relevance of a hypertext document with respect to the focus topics, and a distiller that identifies hypertext nodes that are great access points to many relevant pages within a few links We report on extensive focused-crawling experiments using several topics at different levels of specificity Focused crawling acquires relevant pages steadily while standard crawling quickly loses its way, even though they are started from the same root set Focused crawling is robust against large perturbations in the starting set of URLs It discovers largely overlapping sets of resources in spite of these perturbations It is also capable of exploring out and discovering valuable resources that are dozens of links away from the start set, while carefully pruning the millions of pages that may lie within this same radius Our anecdotes suggest that focused crawling is very effective for building high-quality collections of Web documents on specific topics, using modest desktop hardware © 1999 Published by Elsevier Science BV All rights reserved

TL;DR: In this paper, the authors present a web resource for the prediction of the biological activity spectra of organic compounds based on their structural formulas for more than 4000 types of biological activity with average accuracy above 95% (http://www.way2drug.com/passonline ).
Abstract: The freely accessible web resource PASS Online is presented. This resource is designed for the prediction of the biological activity spectra of organic compounds based on their structural formulas for more than 4000 types of biological activity with average accuracy above 95% (
http://www.way2drug.com/passonline
). The prediction is based on an analysis of the structure-activity relationships in the training set containing information on the structure and biological activity of more than 300000 organic compounds. The possibilities and limitations of this approach are described. Recommendations are given for interpreting the prediction results. Examples are given for the practical use of the PASS Online web resource in order to establish priorities for chemical synthesis and biological testing of substances on the basis of prediction results. The further trends are considered for the using PASS Online as an Internet platform for joint projects of academic researchers for the search and development of new pharmaceutical agents.

TL;DR: M is presented, an annotation tool which provides both automated and semi-automated support for annotating web pages with semantic contents and integrates a web browser with an ontology editor and provides open APIs to link to ontology servers and for integrating information extraction tools.
Abstract: An important precondition for realizing the goal of a semantic web is the ability to annotate web resources with semantic information. In order to carry out this task, users need appropriate representation languages, ontologies, and support tools. In this paper we present MnM, an annotation tool which provides both automated and semi-automated support for annotating web pages with semantic contents. MnM integrates a web browser with an ontology editor and provides open APIs to link to ontology servers and for integrating information extraction tools. MnM can be seen as an early example of the next generation of ontology editors, being web-based, oriented to semantic markup and providing mechanisms for large-scale automatic markup of web pages.

TL;DR: The DNS Security Extensions (DNSSEC) as discussed by the authors are a collection of resource records and protocol modifications that provide source authentication for the DNS, including public key (DNSKEY), delegation signer (DS), resource record digital signature (RRSIG), and authenticated denial of existence (NSEC).
Abstract: This document is part of a family of documents that describe the DNS
Security Extensions (DNSSEC). The DNS Security Extensions are a
collection of resource records and protocol modifications that provide
source authentication for the DNS. This document defines the public
key (DNSKEY), delegation signer (DS), resource record digital
signature (RRSIG), and authenticated denial of existence (NSEC)
resource records. The purpose and format of each resource record is
described in detail, and an example of each resource record is given.
This document obsoletes RFC 2535 and incorporates changes from all
updates to RFC 2535. [STANDARDS-TRACK]

TL;DR: Sindice, a lookup index over resources crawled on the Semantic Web, allows applications to automatically retrieve sources with information about a given resource and allows resource retrieval through inverse-functional properties.
Abstract: Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The "linked data" approach, which mandates that resource URIs should be de-referenced and yield meta-data about the resource, helps but is only a partial solution. We present Sindice, a lookup index over resources crawled on the Semantic Web. Our index allows applications to automatically retrieve sources with information about a given resource. In addition we allow resource retrieval through inverse-functional properties, offer full-text search and index SPARQL endpoints.
