quotefinder facilitates finding different takes on European
affairs. It provides an interactive interface to explore and filter
tweets by all members of the European Parliament who are on Twitter, and
to visualise word frequencies as wordclouds. It is possible to filter
contents based on keywords, hashtags, political affiliation and language
of the tweet. A different interface allows for interactively exploring
textual contents published by EU-institutions such as press-releases. In
this case, available visualisations include time series in order to
highlight changes in the relative prominence of certain issues within
the official EU discourse. Finally, the
quotefinder facilitates the
exploration of trending issues related to European affairs across
different languages by providing an alternative interface to read news
gathered by EMM Newsbrief.
The Quote Finder is based on a purposefully created open source package for the R programming language that effectively deals with data gathering and powers the interactive interface available on EDJNet’s website.
The procedure for data collection and deployment of web apps are documented on the package’s website, making it possible to replicate, expand, or adapt the Quote Finder web apps to other use cases.
The web interface generated by the
quotefinder is currently deployed
on EDJNet’s website. Follow this link for a full-screen
quotefinder interface has currently three separate settings.
Looking at a live
may be best, but for reference, here are three screenshots.
This is an R package, that you can install as usual with:
Its central component is a web interface, created with Shiny, and is ported and updated from a previous version of the Quote Finder. In addition to the web interface, the package includes a number of convenience functions that facilitate gathering systematically the data fed to the interface, as well as Dockerfiles that facilitate its deployment in production.
These tools should make it possible to have instances of the
quotefinder that are dedicated to a specific issue, or to a context
completely unrelated to its initial use. This is the long-term goal of
the package, but at the current stage adaptation and deployment are
admittedly not so straightforward. The Shiny app itself is a port of a
previous app built incrementally, and does not make use of modules.
The re-design of the
quotefinder as an R package make however these
goals more realistic.
Admirers of beautiful code should look elsewhere. People interested in the long journey from a complex Shiny app built by a relatively inexperienced user to what may be a good practice of how to package a Shiny app that collects data from multiple sources and facilitate its use in production, are encouraged to follow the development of this repository.
Long-term goals include:
quotefinderon an own server with containers (not so far, but even some of the package vignettes that have been included included are still not finalised)
