Semalt: Les conseils de données Web Scrape - Ne manquez pas!

by
Dec 01, 2017

Lorsque vous ne pouvez pas obtenir les données requises dans un site Web, sont d'autres méthodes que l'on peut utiliser pour obtenir ces problèmes nécessaires. Par exemple, on peut obtenir les données à partir d'API Web, extraire des données à partir de divers fichiers PDF ou même à partir de sites Web de scrape d'écran. L'extraction de données à partir de fichiers PDF est une tâche ardue car le format PDF ne contient généralement pas les informations exactes dont vous pourriez avoir besoin. D'autre part, lors du processus de scrappage d'écran, le contenu extrait est structuré par un code ou par l'utilisation d'un utilitaire de grattage. Il peut être difficile d'obtenir des données Web de rebut, mais une fois que l'on a une idée de ce qu'il faut faire, cela devient facile.

Données lisibles par machine

L'un des principaux objectifs du scrap web est de pouvoir accéder à des données lisibles par une machine. Ces données sont créées par ordinateur pour le traitement, et certains de ses exemples de format incluent XML, CSV, fichiers Excel et Json. Les données lisibles par machine sont l'un des moyens que l'on peut utiliser pour obtenir des données Web, car elles sont simples et ne nécessitent pas un haut niveau de technique pour les traiter.

Scraping sites

La récupération de sites Web est l'une des méthodes les plus couramment utilisées pour obtenir l'information requise. Il y a des cas où les sites Web ne fonctionnent pas correctement.

Bien que le grattage sur le Web soit préféré, il existe plusieurs facteurs qui rendent le grattage plus compliqué. Certains d'entre eux incluent le code HTML qui est mal formaté et le blocage d'accès en bloc. Les barrières légales peuvent également être un problème dans le traitement des données Web de raclage car il y a certaines personnes qui ignorent l'utilisation des licences. Dans certains pays, cela est considéré comme un sabotage. Les outils qui peuvent aider à extraire ou à extraire des informations incluent les services Web et certaines extensions de navigateur en fonction de l'outil de navigation utilisé. Les données web de Scrape peuvent être trouvées dans Python ou même PHP. Bien que le processus nécessite beaucoup de compétences, il peut être facile si le site Web que vous utilisez est le bon.
