Semalt levert nuttige problemen op Top 5 Web Scrapers

Vaak wordt de informatie die we nodig hebben opgesloten in een site en we kan het niet goed schrapen of kruipen. Hoewel sommige sites inspanningen leveren om gegevens in schone en gestructureerde indelingen weer te geven, kunnen de andere geen webcrawl- of gegevensschraapfaciliteit bieden. Dat is de reden waarom we toegang moeten hebben tot de beste webcrawers, mijnwerkers en scrapers. Hier hebben we de top vijf instrumenten in dit opzicht besproken.

1. Webhose.io:

Webhose.io stelt ons in staat om de real-time gegevens van online bronnen en sites te krijgen. Het beste deel is dat dit programma de sites gemakkelijk opslaat en crawlt en gegevens presenteert in een schoon en overzichtelijk formaat. Het stelt ons ook in staat om gegevens te schrapen op basis van hun zoekwoorden, zinsdelen, talen en de natuur. De definitieve resultaten kunnen worden verkregen in de vorm van XML-, RSS- en JSON-bestanden. Hoewel dit programma kosteloos is, hebt u toegang tot de premiumversie als u Webhose.io voor commerciële doeleinden wilt gebruiken. Met het betaalde abonnement kunt u meerdere HTTP-verzoeken naar de hoofdserver verzenden, zodat u eenvoudig de sites kunt schrapen en crawlen.

2..Scrapy:

Scrapy is een krachtig en verbazingwekkend schrapend en kruipend raamwerk op internet. Het beste deel is dat dit programma wordt ondersteund door een community van experts, waarmee je altijd en overal contact kunt opnemen voor nuttige tips en tutorials. Het helpt je gegevens te schrapen en te ontleden en slaat het op in verschillende indelingen zoals CSV en JSON.

3. Outwit Hub:

Als je je niet comfortabel voelt met codes, biedt Outwit Hub je de nuttige visuele interface, zodat je gemakkelijk de gegevens kunt crawlen en ontginnen. De gehoste versie is beschikbaar op de officiële site en de gratis versie kan worden gedownload vanuit elke online winkel. Outwit Hub is een Firefox-extensie waarvoor je geen programmeervaardigheden nodig hebt.

4. Octoparse:

Net als Outwit Hub is Octoparse een krachtige webschraper, crawler en dataminer. Het behandelt zowel statische als dynamische sites met behulp van Javascript, cookies, omleidingen en AJAX. Dit webprogramma helpt bij het extraheren van een site of blog en extraheert zowel basis- als geavanceerde soorten gegevens. Alle waardevolle informatie die u nodig hebt, kunt u vinden in het cloudopslaggebied van Octoparse. Hiermee kunt u binnen een uur bulkwebsites extraheren en krijgt u de beste kwaliteit met de Octoparse API. Laat me je vertellen dat deze freeware alleen Windows ondersteunt en niet beschikbaar is voor andere besturingssystemen.

5. Web Scraper for Chrome:

Als u Google Chrome als uw primaire webbrowser heeft, moet u kiezen voor Web Scraper. Het is een uitstekend crawl- en mijnprogramma waarmee u sitemaps kunt maken voor zowel uw persoonlijke blogs als zakelijke websites. U hoeft deze scraper alleen maar te downloaden, te installeren en toe te voegen aan uw Chrome-browser en te zien hoe deze gegevens van uw websites haalt. U kunt ook de sitemaps importeren of de sjablonen gebruiken om het algehele uiterlijk en de prestaties van uw website te verbeteren. Het bewaart uw uitgepakte gegevens in de CSV-bestanden of in zijn eigen archiefmap.
