Despite all the advancements in web APIs and interoperability, it's inevitable that, at some point in your career, you will have to "scrape" content from a website that was not built with web services in mind. And, despite its sometimes less-than-stellar reputation, web scraping is usually an entire legitimate activity-for example, to capture data from an old version of a website for insertion into a modern CMS. This book, written by scraping expert Matthew Turland, covers web scraping techniques and topics that range from the simple to exotic using a variety of technologies and frameworks: . Understanding HTTP requests . The PHP HTTP streams wrapper . cURL . pecl_http . PEAR: HTTP . Zend_Http_Client . Building your own scraping library . Using Tidy . Analyzing code with the DOM, SimpleXML and XMLReader extensions . CSS selector libraries . PCRE pattern matching . Tips and Tricks . Multiprocessing / parallel processing

There's a wealth of data online, but sorting and gathering it by hand can be tedious and time consuming. Rather than click through page after endless page, why not let bots do the work for you? Webbots, Spiders, and Screen Scrapers will show you how to create simple programs with PHP/CURL to mine, parse, and archive online data to help you make informed decisions. Michael Schrenk, a highly regarded webbot developer, teaches you how to develop fault-tolerant designs, how best to launch and schedule the work of your bots, and how to create Internet agents that: –Send email or SMS notifications to alert you to new information quickly –Search different data sources and combine the results on one page, making the data easier to interpret and analyze –Automate purchases, auction bids, and other online activities to save time Sample projects for automating tasks like price monitoring and news aggregation will show you how to put the concepts you learn into practice. This second edition of Webbots, Spiders, and Screen Scrapers includes tricks for dealing with sites that are resistant to crawling and scraping, writing stealthy webbots that mimic human search behavior, and using regular expressions to harvest specific data. As you discover the possibilities of web scraping, you'll see how webbots can save you precious time and give you much greater control over the data available on the Web.

Every day, more and more kinds of historical data become available, opening exciting new avenues of inquiry but also new challenges. This updated and expanded book describes and demonstrates the ways these data can be explored to construct cultural heritage knowledge, for research and in teaching and learning. It helps humanities scholars to grasp Big Data in order to do their work, whether that means understanding the underlying algorithms at work in search engines or designing and using their own tools to process large amounts of information.Demonstrating what digital tools have to offer and also what 'digital' does to how we understand the past, the authors introduce the many different tools and developing approaches in Big Data for historical and humanistic scholarship, show how to use them, what to be wary of, and discuss the kinds of questions and new perspectives this new macroscopic perspective opens up. Originally authored 'live' online with ongoing feedback from the wider digital history community, Exploring Big Historical Data breaks new ground and sets the direction for the conversation into the future.Exploring Big Historical Data should be the go-to resource for undergraduate and graduate students confronted by a vast corpus of data, and researchers encountering these methods for the first time. It will also offer a helping hand to the interested individual seeking to make sense of genealogical data or digitized newspapers, and even the local historical society who are trying to see the value in digitizing their holdings.
