Wikimedia Foundation the nonprofit that hosts Wikipedia and our other free knowledge projects. We want to make it easier for everyone to share what they know. To do this, we keep Wikipedia and Wikimedia sites fast, reliable, and available to all. We protect the values and policies that allow free knowledge to thrive. We build new features and tools to make it easy to read, edit, and share from the Wikimedia sites. Above all, we support the communities of volunteers around the world who edit, improve, and add knowledge across Wikimedia projects. Wikimedia Foundation

RESTBase content API

This provides developers code-level access to the entire Wikipedia reference. The goal of this API is to provide direct, high-level access to the data contained in the MediaWiki databases. Client programs can use the API to login, get data, and post changes. The API supports thin web-based JavaScript clients, such as Navigation popups or LiveRC, end-user applications (such as vandal fighter), and can be accessed by another web site (tool server's utilities). The API uses RESTful calls and supports a wide variety of formats including XML, JSON, PHP, YAML and others. Wikipedia REST API | Programmable Web

Wikipedia API Coding Challenge #75

In this coding challenge, I attempt to make a “Wikipedia web crawler” in JavaScript. It randomly crawls from topic to topic on Wikipedia using the API and the p5.js library.

Web Scraping

...with Python and Beautiful Soup

...DBpedia

In this talk, the speaker will demonstrate how to build a searchable knowledge graph from scratch. Lots of python tools will be applied during the process. The process includes data wrangling, graph entity indexing, full text search and web visualization. The data sources are from DBpedia.org. Enormous amount of entities are collected and stored to graph database for relationship querying and full text search engine for searching. In the web visualization, a searchable interface and visualized result demonstrate the knowledgable information to customer. Jimmy Lai
