How often do teachers or students ask questions? How often are questions answered, or not? How often do teachers ask questions answered by students, students ask questions answered by teachers, or students ask questions answered by students? Annotation data can provide these and other insights.
The web of linked resources produces a steady flow of emergent capabilities. The web of linked segments increases that flow.
Annotation alone is a powerful way to remix the web. When you add Twitter into the mix, possibilities multiply.
Recently we decided to keep better track of tweets, blog posts, and other web resources that mention and discuss our product. There are two common ways to do that: send links to a list maintainer, or co-edit a shared list of links. And here's a third way, less common but arguably more powerful and flexible: tag the web resources in situ.
Introduction Hypothesis delivers a set of components and capabilities that work together to enable a wide range of annotation-powered applications. Here we provide an architectural overview. The major components are: An annotation viewer and editor that runs as an overlay in the browser ("the client"). An annotation service that stores, searches, and displays annotations, manages [...]
Acknowledgement of uncertainty is one of the core principles of rational inquiry. We're more likely to trust news sources that signal their credibility by upholding that principle. If news aggregators can detect and process that signal at scale, they can help me separate the wheat from the chaff. But how will we teach them to do that?
Hypothesis uses common metadata conventions to identify and alias documents so we can sync annotations across multiple versions of the same document. Among the metadata conventions used are: Search-oriented HTML tags DOI-related HTML tags PDF metadata PDF-related HTML metadata Some of these conventions are deployed to guide search engines; others to help organize scholarly literature. [...]
A new wildcard URL search API makes it possible to monitor entire websites for annotation activity. Here we show how you can use that capability to send notifications to Slack.
Radio buttons, checkboxes, and input boxes are the usual ways to answer survey questions. But what if the answer to a question is a selection in a document?
