An Overview of the 50 Most Common Web Scraping Tools
AN OVERVIEW OF THE 50 MOST COMMON WEB SCRAPING TOOLS WEB SCRAPING IS THE PROCESS OF USING BOTS TO EXTRACT CONTENT AND DATA FROM A WEBSITE. UNLIKE SCREEN SCRAPING, WHICH ONLY COPIES PIXELS DISPLAYED ON SCREEN, WEB SCRAPING EXTRACTS UNDERLYING CODE — AND WITH IT, STORED DATA — AND OUTPUTS THAT INFORMATION INTO A DESIGNATED FILE FORMAT. While legitimate uses cases exist for data harvesting, illegal purposes exist as well, including undercutting prices and theft of copyrighted content. Understanding web scraping bots starts with understanding the diverse and assorted array of web scraping tools and existing platforms. Following is a high-level overview of the 50 most common web scraping tools and platforms currently available.

RNDr. Irena Holubov´a,Ph.D., department Abstract: Creation of web wrappers (i.e programs that extract data from the web) is a subject of study in the field of web data extraction. Designing a domain- specific language for a web wrapper is a challenging task, because it introduces trade-offs between expressiveness of a wrapper’s language and safety. In addition, little attention has been paid to execution of a wrapper in restricted environment. In this thesis, we present a new wrapping language – Serrano – that has three goals in mind. (1) Ability to run in restricted environment, such as a browser extension, (2) extensibility, to balance the tradeoffs between expressiveness of a command set and safety, and (3) processing capabilities, to eliminate the need for additional programs to clean the extracted data. -

COMPUTING FUNDAMENTALS AND OFFICE PRODUCTIVITY TOOLS IT111 REFERENCENCES: LOCAL AREA NETWORK BY DAVID STAMPER, 2001, HANDS ON NETWORKING FUNDAMENTALS 2ND EDITION MICHAEL PALMER 2013 NETWORKING FUNDAMENTALS Network Structure WHAT IS NETWORK Network • An openwork fabric; netting • A system of interlacing lines, tracks, or channels • Any interconnected system; for example, a television-broadcasting network • A system in which a number of independent computers are linked together to share data and peripherals, such as hard disks and printers Networking • involves connecting computers for the purpose of sharing information and resources STAND ALONE ENVIRONMENT (WORKSTATION) users needed either to print out documents or copy document files to a disk for others to edit or use them. If others made changes to the document, there was no easy way to merge the changes. This was, and still is, known as "working in a stand-alone environment." STAND ALONE ENVIRONMENT (WORKSTATION) Copying files onto floppy disks and giving them to others to copy onto their computers was sometimes referred to as the "sneakernet." GOALS OF COMPUTER NETWORKS • increase efficiency and reduce costs Goals achieved through: • Sharing information (or data) • Sharing hardware and software • Centralizing administration and support More specifically, computers that are part of a network can share: • Documents (memos, spreadsheets, invoices, and so on). • E-mail messages. • Word-processing software. • Project-tracking software. • Illustrations, photographs, videos, and audio files. • Live audio and video broadcasts. • Printers. • Fax machines. • Modems. • CD-ROM drives and other removable drives, such as Zip and Jaz drives. • Hard drives. GOALS OF COMPUTER NETWORK Sharing Information (or Data) • reduces the need for paper communication • increase efficiency • make nearly any type of data available simultaneously to every user who needs it. -

Manuscript submitted January 27, 2015; accepted April 28, 2015 doi: 10.17706/jsw.10.5.577-598 Abstract: Information on the Leukemia patients is very crucial by keep track medical history and to know the current status of the patient’s. This paper explains on development of Hematology Information System (HIS) in Hospital Universiti Sains Malaysia (HUSM). HIS is the web application, which is the enhancement of the standalone application system that used previously. The previous system lack of the implementation of security framework and triple ‘A’ elements which are authentication, authorization and accounting. Therefore, the objective of this project is to ensure the security features are implemented and the information safely kept in the server. We are using agile methodology to develop the HIS which the involvement from the user at the beginning until end of the project. The user involvement at the beginning user requirement until implemented. As stated above, HIS is web application that used JSP technology. It can only be access within the HUSM only by using the local Internet Protocol (IP). HIS ease medical doctor and nurse to manage the Leukemia patients. For the security purpose HIS provided password to login, three different user access levels and activity log that recorded from each user that entered the system Key words: Hematology information system, security feature, agile methodology. -

Design of Imacros-Based Data Crawler and the Behavioral Analysis of Facebook Users
Design of iMacros-based Data Crawler and the Behavioral Analysis of Facebook Users Mudasir Ahmad Wani Nancy Agarwal Suraiya Jabin Syed Zeesahn Hussain Research laboratory Research laboratory Department of Computer Department of Computer Department Computer Department Computer Science Science Science Science Faculty of Natural Science Faculty of Natural Science Faculty of Natural Science Faculty of Natural Science Jamia Millia Islamia (A Jamia Millia Islamia (A Jamia Millia Islamia (A Jamia Millia Islamia (A Central University) Central University) Central University) Central University) New Delhi, India New Delhi, India New Delhi, India New Delhi, India [email protected] [email protected] [email protected] [email protected] Abstract Obtaining the desired dataset is still a prime challenge faced by researchers while analyzing Online Social Network (OSN) sites. Application Programming Interfaces (APIs) provided by OSN service providers for retrieving data impose several unavoidable restrictions which make it difficult to get a desirable dataset. In this paper, we present an iMacros technology-based data crawler called IMcrawler, capable of collecting every piece of information which is accessible through a browser from the Facebook website within the legal framework which permits access to publicly shared user content on OSNs. The proposed crawler addresses most of the challenges allied with web data extraction approaches and most of the APIs provided by OSN service providers. Two broad sections have been extracted from Facebook user profiles, namely, Personal Information and Wall Activities. The present work is the first attempt towards providing the detailed description of crawler design for the Facebook website. Keywords: Online Social Networks, Information Retrieval, Data Extraction, Behavioral Analysis, Privacy and Security. -

Instrumentation De Navigateurs Pour L'analyse De Code Javascript
Under the DOM : Instrumentation de navigateurs pour l’analyse de code JavaScript Erwan Abgrall1,2 et Sylvain Gombault2 [email protected] [email protected] 1 DGA-MI 2 IMT Atlantique - SRCD Résumé. Les attaquants font, de plus en plus, usage de langages dy- namiques pour initier leurs attaques. Dans le cadre d’attaques de type « point d’eau » où un lien vers un site web piégé est envoyé à une victime, ou lorsqu’une application web est compromise pour y héberger un « ex- ploit kit », les attaquants emploient souvent du code JavaScript fortement obfusqué. De tels codes sont rendus adhérents au navigateur par diverses techniques d’anti-analyse afin d’en bloquer l’exécution au sein des ho- neyclients. Cet article s’attachera à expliquer l’origine de ces techniques, et comment transformer un navigateur web « du commerce » en outil d’analyse JavaScript capable de déjouer certaines de ces techniques et ainsi de faciliter notre travail. 1 Introduction Cet article a pour objectif d’introduire le lecteur au monde de la désobfucation JavaScript, et de proposer une nouvelle approche à cette problématique dans le cadre de l’analyse de sites malveillants, plus com- munément appelés « exploit kits ». Il va de soi que la compréhension des mécanismes de base du langage JavaScript est un pré-requis. Le lecteur souhaitant se familiariser avec celui-ci pourra lire l’excellent Eloquent- JavaScript 3. Bien entendu l’analyse de codes malveillants quels qu’ils soient doit se faire dans un environnement correspondant aux risques in- duits 4 5. Enfin, pour vous faire la main, un ensemble de sites malveillants potentiellement utiles aux travaux de recherches est proposé en ligne 6. -
