Semalt Experte erklärt, wie man mit Scrappern arbeitet

Jan 25, 2018

Screen Scraper sind Data-Mining-Tools, die Daten von Standorten extrahieren und Benutzern in fast jedes Format. Das Datenformat könnte API, CSV, MySQL, MS SQL, Access und Excel sein. Es gibt mehrere Synonyme für Screen Scraper, einschließlich Website-Ripper, HTML-Scraper, automatisierte Datensammler und Web-Extraktoren.

In der Vergangenheit arbeiteten Menschen auf Mainframe-Computern. Sie mussten textbasierte oder Greenscreen-Schnittstellen verwenden, um mit wichtigen Geschäftsinformationen zu arbeiten. Und sie benutzten Screen Scraping, um Text von einem Computerbildschirm zu lesen. Heute bezieht sich Screen Scraping jedoch darauf, Daten von Websites zu erhalten, um sie für andere Zwecke zu nutzen. Screen Scraper können Daten von mehreren Websites im Internet durchsuchen, um erforderliche Daten zu sammeln.

Wie funktioniert ein Screen Scraper? Ein Screen Scraper kann mit Crawlern oder Spidern verglichen werden. Diese Crawler greifen auf Millionen von Websites zu, die mehrere Webseiten enthalten. Die Spinne durchsucht systematisch diese Seiten, um Daten zu sammeln und zu indexieren, nach denen sie sucht. Die gesammelten und indizierten Daten werden dann dem Endnutzer des Internets als Suchmaschinenergebnisse präsentiert. Solche Daten werden normalerweise in einer organisierten Weise präsentiert, die speziell auf den menschlichen Gebrauch zugeschnitten ist.

Danach wird ein Screen Scraper den Code einer Site durchsuchen und den unerwünschten Code herausfiltern. Daher ist die primäre Funktion eines Screen Scrapers die Suche nach nützlichen Daten. Es extrahiert diese Daten und präsentiert sie als eine einfache Datenbank ohne zusätzliche Funktionen.

Screen Scraper durchforsten häufig die HTML-Codierung einer Site, um auf ihre Daten zuzugreifen. Sie können auch andere Skriptsprachen wie PHP oder JavaScript durchsuchen. Die gewonnenen Daten können dann als HTML dargestellt werden, so dass Web-Benutzer mit ihren Browsern darauf zugreifen können. Es kann auch als Textdaten gespeichert werden.

Es gibt verschiedene Anwendungen für Screen Scraper, aber im Wesentlichen wird ein Screen Scraper von Unternehmen verwendet, um relevante Informationen aus einer Reihe von Keyword-bezogenen Sites zu extrahieren, um Vergleichsdaten, Tabellenkalkulationen, Diagramme und Grafiken zu generieren in Präsentationen oder Berichten. Screen Scraping Tools sparen viel Zeit, weil sie in einem Bruchteil der Zeit große Datenmengen aus dem Internet extrahieren. Eine Person, die die gleiche Aufgabe ausführt, müsste nach relevanten Websites suchen, auf Links klicken und jede Webseite durchsuchen, um die wichtigen Informationen zu finden, die sie benötigt. Es kann extrem ermüdend und zeitaufwendig sein.

Während Screen Scraper ein Segen für Websurfer und Webmaster sein können, können sie auch für egoistische Zwecke verwendet werden. Einzelpersonen oder Unternehmen, die beispielsweise Spam als eine ihrer Werbetechniken verwenden, können Screen Scraper nutzen, um E-Mail-Adressen von Websites illegal zu entfernen.

Gibt es rechtliche Konsequenzen davon, dass andere Websites ohne Erlaubnis gekratzt werden? Obwohl ein Bildschirmschaber ein wichtiges Computerprogramm ist, ist es wichtig, die Gesetzmäßigkeiten und die Ethik bei der Verwendung zu beachten. Es gibt legale und illegale Formen des Screen Scraping. Das Extrahieren von Daten von der Website einer anderen Person ohne Erlaubnis kann das Urheberrecht verletzen.

Andrea Fischer

George, your expertise on scrappers is evident! How can one efficiently extract data from websites with a large number of pages or deep hierarchies?

George Forrest

Thank you, Andrea! Extracting data efficiently from websites with large page counts or deep hierarchies requires careful planning. Techniques like utilizing sitemaps, following hierarchical crawling strategies, and implementing depth-first or breadth-first scraping algorithms can help navigate and extract data from such websites more efficiently. Analyzing website structures and optimizing scraping scripts to target specific data elements can also aid in the efficient extraction of desired information.

Robert Koch

George, great insights on scrappers! Can you recommend any techniques for effectively handling websites with rate limiting mechanisms in place?

George Forrest

Thank you, Robert! Websites with rate limiting mechanisms can pose challenges to scrapers. Techniques like implementing intelligent rate limiting on the scraper's side to stay within the allowed limits, using rotating proxies to distribute requests, and incorporating delay mechanisms between requests can help effectively handle rate limiting. Monitoring server responses for rate limit headers can also aid in dynamically adjusting scraping rates.

Sophia Becker

George, your article on scrappers was very informative! How can one handle websites with different languages or character encodings during the scraping process?

George Forrest

Thank you, Sophia! Handling websites with different languages or character encodings requires special consideration.

Additionally, having reliable translation mechanisms or language-specific processing pipelines can aid in extracting meaningful insights from scraped content in various languages.

Jonas Schumacher

George, your insights on working with scrappers were really helpful! What are some indicators to determine if a scraper needs optimization or if it's functioning efficiently?

George Forrest

Thank you, Jonas! Indicators like the scraping speed, data accuracy, and robustness in handling website changes can provide insights into whether a scraper needs optimization. Monitoring server response times, analyzing scraping logs for errors or exceptions, and periodically evaluating the quality and consistency of the scraped data against trusted sources or benchmarks can help identify areas for optimization and ensure efficient and reliable scraping functionality.

Carolina Hartmann

George, great article! I'm curious to know if there are any challenges or limitations when scraping websites with JavaScript-heavy content or AJAX-loaded data?

George Forrest

Thank you, Carolina! Websites with JavaScript-heavy content or AJAX-loaded data can present challenges for scrapers. Utilizing headless browser frameworks like Puppeteer that can interpret JavaScript, analyzing network traffic to identify AJAX requests and their associated data, or exploring alternative sources like APIs for fetching the required data can help overcome these challenges and ensure comprehensive scraping of such websites.

Melanie Becker

George, your article on working with scrappers was insightful! I'm curious, are there any industry regulations or standards related to web scraping?

George Forrest

Thank you, Melanie! While there are no specific industry-wide regulations governing web scraping, there are regulations pertaining to data privacy, copyright, and terms of service that may impact scraping practices. Industries like finance, healthcare, and research often have specific regulations related to data usage and privacy. It's important to be aware of and adhere to these regulations, along with respecting individual websites' terms of service, to ensure compliance and ethical scraping practices.

Marcel Thiele

George, your expertise on scrappers is evident! What are your thoughts on using scraping as a fundamental part of a business's data acquisition strategy?

George Forrest

Thank you, Marcel! Using scraping as a fundamental part of a business's data acquisition strategy can provide valuable insights and a competitive edge. It enables access to unique data sources, real-time information, and comprehensive data gathering. However, it's important to consider legal and ethical factors, ensure responsible data usage, invest in robust scraping infrastructure, and maintain data quality to fully leverage scraping's potential as a strategic asset.
