This repository contains the source code for the web application driving the JSTOR Labs Topicgraph demonstration app. The Topicgraph app was developed as part of the "Reimagining the Monograph" project conducted by JSTOR Labs during the Fall of 2016.

Installing and running locally

This application was developed using the Angular2 javascript framework and can be installed and run using either the Node Package Manager (NPM) or yarn.

You can use npm, but it's recommended to use yarn as it installs a lot faster and has other benefits . Make sure you are using yarn version 0.16.0 or newer (check with 'yarn --version')

yarn start

REST APIs provided by JSTOR Labs are used for in the analysis and topic inference of the monographs.
These APIs should be considered experimental and subject to change.

This word coordinate text is used in word highlighting.

getTopicWords - Retrieves the words associated with a specified topic.

PDF analyzer service
