3 manières différentes de raclage de Web de Semalt

L'importance et la nécessité d'extraire ou de racler des données des sites Web sont devenues de plus en plus populaire avec le temps. Souvent, il est nécessaire d'extraire des données des sites Web de base et avancés. Parfois, nous extrayons manuellement des données, et parfois nous devons utiliser un outil comme l'extraction manuelle des données ne donne pas les résultats souhaités et précis.

Que vous soyez préoccupé par la réputation de votre entreprise ou de votre marque, que vous souhaitiez surveiller les conversations en ligne entourant votre entreprise, effectuer des recherches ou garder un œil sur impulsion d'une industrie ou d'un produit particulier, vous avez toujours besoin de gratter les données et de passer de la forme non organisée à la forme structurée.

Nous devons ici discuter de trois façons différentes d'extraire des données du Web.

1. Construisez votre robot d'exploration personnel.

2. Utilisez les outils de raclage.

3. Utilisez les données pré-emballées.

1. Construisez votre Crawler:

La première et la plus célèbre façon de s'attaquer à l'extraction de données est de construire votre crawler. Pour cela, vous devrez apprendre quelques langages de programmation et maîtriser les aspects techniques de la tâche..Vous aurez également besoin d'un serveur évolutif et agile pour stocker et accéder aux données ou au contenu Web. L'un des principaux avantages de cette méthode est que les robots d'exploration seront personnalisés en fonction de vos besoins, ce qui vous donnera un contrôle complet sur le processus d'extraction des données. Cela signifie que vous obtiendrez ce que vous voulez réellement et que vous pourrez récupérer des données sur autant de pages Web que vous le souhaitez sans vous soucier du budget.

2. Utilisez les Extracteurs de Données ou les Outils de Grattage:

Si vous êtes un blogueur professionnel, un programmeur ou un webmaster, vous n'avez peut-être pas le temps de construire votre programme de grattage. Dans ce cas, vous devez utiliser les extracteurs de données ou les outils de raclage déjà existants. Import.io, Diffbot, Mozenda et Kapow sont parmi les meilleurs  outils de grattage de données Web  sur Internet. Ils viennent à la fois dans les versions gratuites et payantes, ce qui rend facile pour vous de gratter les données de vos sites préférés instantanément. Le principal avantage de l'utilisation de ces outils est qu'ils vont non seulement extraire des données pour vous mais aussi les organiser et les structurer en fonction de vos exigences et de vos attentes. Cela ne vous prendra pas beaucoup de temps pour mettre en place ces programmes, et vous obtiendrez toujours des résultats précis et fiables. De plus, les  outils de raclage web  sont bons lorsque l'on traite de l'ensemble fini de ressources et que l'on veut surveiller la qualité des données tout au long du processus de raclage. Il convient aux étudiants et aux chercheurs, et ces outils les aideront à mener correctement des recherches en ligne.

3. Données pré-emballées de la plateforme Webhose.io:

La plate-forme Webhose.io nous donne accès à des données utiles et bien extraites. Avec la solution DaaS (Data-as-a-Service), vous n'avez pas besoin d'installer ou de maintenir vos programmes de scrappage Web et vous pourrez facilement obtenir des données pré-explorées et structurées. Tout ce que nous devons faire est de filtrer les données en utilisant les API afin que nous obtenions les informations les plus pertinentes et les plus précises. Depuis l'année dernière, nous pouvons également accéder aux données web historiques avec cette méthode. Cela signifie que si quelque chose était perdu précédemment, nous pourrions y accéder dans le dossier Achieve de Webhose.io.
