Rss feed example website10/31/2023 ![]() ![]() Is our case, we will publish messages to three topics : A topic is a resource that groups related messages exchanged between publishers and subscribers. To start using Cloud Pub/Sub, we should create a topic. You can get 300$ free credits that you can use for 12 months. You can start using GCP for free with your Gmail account. Cloud Storage will be used to persist the resulting articles as Json files.Cloud Function will be used to make our Python code available as a service,.Cloud Pub/Sub will be used to build an event-driven solution to start a search-and-extract process,.In this section we will use Google Cloud Platform (GCP) to build a scalable solution for searching any news related to a keyword, extracting the news articles and storing them for future processing: Here is a Python implementation in order to process one article:Īutomatization using Google Cloud Platform The pandas library will be used to collect articles in DataFrame format: pip install pandas.The beautifulsoup4 library will be used to extract data from an html content type: pip install beautifulsoup4.The requests library will be used to request http URLs: pip install requests.To implement this solution, lets install some useful libraries: ![]() The assumption is that the main article should represent the highest web page content, while the other web page components, like ads, images, links, promoted articles summaries, etc., should be individually marginal. ![]() select the longest paragraph as the main article.concatenate paragraphs under the same parent hierarchy,.for each paragraph, construct its patents elements hierarchy,.extract all paragraph elements inside the page body,.The solution proposed is easy to implement, not perfect, but worked well when tested over different websites: However, not all paragraph blocks in a web page are related to the main article, so we should find a way to concatenate only paragraphs of interest. So, we might consider extracting all paragraph elements within a page and concatenating them as a single article. ![]()
