Analyseurs de pages Web ou comment obtenir des données que vous voulez sur le net

by
Jan 30, 2018

Tous les sites Web modernes et les blogs génèrent leurs pages en utilisant JavaScript (comme avec AJAX, jQuery et d'autres techniques similaires). Ainsi, l'analyse de page Web est parfois utile pour déterminer l'emplacement d'un site et de ses objets. Une bonne page Web ou un analyseur HTML est capable de télécharger le contenu et les codes HTML et peut entreprendre plusieurs tâches d'exploration de données à la fois. GitHub et ParseHub sont les deux scrapers de page Web les plus utiles qui peuvent être utilisés pour les sites basiques et dynamiques. Le système d'indexation de GitHub est similaire à celui de Google, tandis que ParseHub fonctionne en analysant continuellement vos sites et en mettant à jour leur contenu. Si vous n'êtes pas satisfait des résultats de ces deux outils, vous devriez opter pour Fminer. Cet outil est principalement utilisé pour gratter les données du net et analyser les différentes pages Web. Cependant, Fminer n'a pas de technologie d'apprentissage automatique et ne convient pas à des projets sophistiqués d'extraction de données. Pour ces projets, vous devriez opter pour GitHub ou ParseHub.

 1. ParseHub: 

Parsehub est un outil de raclage de bande qui prend en charge des tâches d'extraction de données sophistiquées. Les webmasters et les programmeurs utilisent ce service pour cibler les sites qui utilisent JavaScript, les cookies, AJAX et les redirections. ParseHub est équipé de la technologie d'apprentissage automatique, analyse différentes pages Web et HTML, lit et analyse les documents Web et récupère les données selon vos besoins. Il est actuellement disponible en tant qu'application de bureau pour les utilisateurs Mac, Windows et Linux. Une application Web de ParseHub a été lancée il y a quelque temps, et vous pouvez exécuter jusqu'à cinq tâches d'extraction de données à la fois avec ce service. L'une des caractéristiques les plus distinctives de ParseHub est qu'il est gratuit et qu'il extrait des données d'Internet en quelques clics. Êtes-vous en train d'analyser une page Web? Voulez-vous collecter et extraire des données d'un site complexe? Avec ParseHub, vous pouvez facilement entreprendre plusieurs tâches de raclage de données et ainsi économiser votre temps et votre énergie.

 2. GitHub: 

Tout comme ParseHub, GitHub est un puissant analyseur de pages Web et un grattoir de données. L'une des caractéristiques les plus distinctives de ce service est qu'il est compatible avec tous les navigateurs Web et systèmes d'exploitation. GitHub est principalement disponible pour les utilisateurs de Google Chrome. Il vous permet de configurer les sitemaps sur la façon dont votre site doit être navigué et quelles données doivent être supprimées. Vous pouvez gratter plusieurs pages Web et analyser HTML avec cet outil. Il peut également gérer des sites avec des cookies, des redirections, AJAX et JavaScript. Une fois le contenu Web entièrement analysé ou récupéré, vous pouvez le télécharger sur votre disque dur ou l'enregistrer au format CSV ou JSON. Le seul inconvénient de GitHub est qu'il ne possède pas de fonctionnalités d'automatisation.

 Conclusion: 

Les deux GitHub et ParseHub sont un bon choix pour gratter un site Web entier ou partiel. De plus, ces outils sont utilisés pour analyser HTML et différentes pages Web. Ils possèdent leurs caractéristiques distinctives et sont utilisés pour extraire des données de blogs, sites de médias sociaux, flux RSS, pages jaunes, pages blanches, forums de discussion, points de vente et portails de voyage.
