Installation

NPM

Clone this repo to your local machine

$ git clone https://github.com/ariecattan/CoRefi.git

Then run the following npm commands to install and run the tool locally.

$ npm install
$ npm run --serve 

CDN

Add the following code your html file.

<script src="https://unpkg.com/vue"></script>
<script src="https://github.com/ariecattan/CoRefi/releases/download/1.4/co-refi.min.js"></script>

<link href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900" rel="stylesheet">
<link href="https://cdn.jsdelivr.net/npm/@mdi/[email protected]/css/materialdesignicons.min.css" rel="stylesheet">
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/vuetify.min.css" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=Material+Icons" rel="stylesheet">

The app can then be embeded as a Web Component

<co-refi json="{html escaped json config}" ></co-refi>

let corefi = document.getElementsByTagName("co-refi")[0].vueComponent;
let results = {tokens:corefi.tokens, mentions:corefi.viewedMentions, tree:corefi.hypernym}
JSON.stringify(results);

Configurate CoRefi

See below the important parameters in the JSON config file:

• mode: (onboarding, annotation, reviewer)
• hypernym: (true or false) whether to allow or not annotation of hierarchy between clusters
• tokens: list of flatten tokens from all documents, each token needs to include {i: incremental index, document: doc_id of the document, text} and optionally paragraph
• mentions: list of candidate mentions to annotate, each mention needs to include {start, end}. In CoRefi, the clustId corresponds to "start-end", the first mention needs to be filled in the annotation mode and all mentions need to have clustId in the onboarding and reviewer mode

The hierarchy of clusters is built using simple drag-and-drop operations. Anntotators may also add notes for each node.

Please refer to our website for more details on the tool functionaly.
