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. -
DLCGI Advanced Uses
DLCGI Advanced Uses Using DLCGI to achieve single sign-on with The Diver Solution In situations where authentication to DiveLine needs to be integrated with an existing authentication scheme, we provide "DLCGI", the DiveLine-Common Gateway Interface interfacing module. The "Common Gateway Interface" is a standard for interfacing external scripts and programs with a web server. How DLCGI works When dlcgi.exe is executed by the webserver, in the context of a user that the web server has already authenticated, it obtains a limited-lifetime one-time password from DiveLine. This password can be passed, via web page redirects, custom web page scripting, etc., to DivePort, NetDiver, or even ProDiver to allow the user to login. The typical strategy for using DLCGI is: 1. Configure DiveLine to accept DLCGI requests from your webserver. 2. Install dlcgi.exe in a scripts directory (e.g. /cgi-bin/) on your CGI-compliant webserver (e.g. IIS, Apache). You configure the name of your DiveLine server and other parameters using dlcgi.cfg in the same directory as the executable. 3. Restrict access to this script so that the webserver will only execute it when the user has already authenticated (e.g. Domain account). Typical uses • DivePort: Users go to the DivePort site, and are redirected to another URL for authentication. That URL, which runs dlcgi.exe, redirects the user back to the DivePort URL with a one-use authentication token. • ProDiver: When ProDiver connects to DiveLine, if configured with a DLCGI URL, it will access the URL in "raw" mode (see below) to obtain a parse-able result file containing a one-use DiveLine authentication token. -
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. -

CGI Scripts: Gateways to World-Wide Web Power
Behavior Research Methods. Instruments. & Computers 1996,28 (2), 165-169 CGI scripts: Gateways to World-Wide Web power JAMES M. KIELEY Miyazaki International CoUege, Miyazaki, Japan The power of the hypertext-based information presentation system known as the World-Wide Web can be enhanced by scripts based on the common gateway interface (CG!) protocol. CG! scripts re siding on a Webserver permit the execution of computer programs that can perform a wide variety of functions that maybe useful to psychologists. Example applications are presented here, along with ref erence information for potential script developers. The majority ofinformation that people access via the permit users to input data by clicking on checkboxes, hypertext-based information presentation system known radio buttons, menus, reset buttons, and submit buttons, as the World-Wide Web (WWW) is actually stored in the and also by typing into text fields (Lemay, 1995). form of static files-that is, text and graphics files that COl was developed by the original programmers ofthe appear a certain way when viewed from a Web browser, UNIX-based CERN and NCSA HTTP Web servers to such as Netscape or Mosaic, because ofa command lan supersede a prior scripting environment called HTBIN. guage known as HTML. HTML, by its original design, is Other Web servers that support scripting, including those a simple command set used to present multimedia infor based on other operating systems, mayor may not use mation that can be accessed asynchronously.

Early applications of COl scripts in bilities ofHTML, and, therefore, the WWW, can be im cluded using them to serve information to a browser that proved with scripts conforming to the common gateway is in a format that is otherwise unreadable, such as an SQL interface (COl) protocol. -

The Common Gateway Interface and Server-Side Programming
WebWeb MasterMaster 11 IFIIFI Andrea G. B. Tettamanzi Université de Nice Sophia Antipolis Département Informatique [email protected] Andrea G. B. Tettamanzi, 2019 1 Unit 3 The Common Gateway Interface and Server-side Programming Andrea G. B. Tettamanzi, 2019 2 Agenda • The Common Gateway Interface • Server-Side Programming Andrea G. B. Tettamanzi, 2019 3 Introduction • An HTTP server is often used as a gateway to a different information system (legacy or not), for example – an existing body of documents – an existing database application • The Common Gateway Interface (CGI) is an agreement between HTTP server implementors about how to integrate such gateway scripts and programs • It was typically (but not exclusively) used in conjunction with HTML forms to build database applications • Nowadays largely superseded by dynamic Web content technologies such as PHP, ASP.NET, Java Servlets, and Node.js Andrea G. B. Tettamanzi, 2019 4 The Common Gateway Interface • The Common Gateway Interface (CGI) is a de facto standard protocol for Web servers to execute an external program that generates a Web page dynamically • The external program executes like a console application running on the same machine as the Web server (the host) • Such program is known as a CGI script or simply as a CGI Andrea G. B. Tettamanzi, 2019 5 How Does That Work? • Each time a client requests the URL corresponding to a CGI program, the server will execute it in real-time – E.g.: GET http://www.example.org/cgi-bin/add?x=2&y=2 • The output of the program will go more or less directly to the client • Strictly speaking, the “input” to the program is the HTTP request • Environment variables are used to pass data about the request from the server to the program – They are accessed by the script in a system-defined manner – Missing environment variable = NULL value – Character encoding is system-defined Andrea G. -
