# nlu-web
A sample application that uses Watson Natural Language Understanding, DBpedia, and IBM Cloud Functions (OpenWhisk).
The client application is implemented with Vue.js. The UI enables a user to enter a url, preferably one that references a news article. The UI invokes a backend that analyzes the article's contents, identifies a subset of relevant entities, then looks up their details using DBpedia. Finally, the results are rendered as cards. Entities with locations will appear on a Google Map.
The backend is implemented using IBM Cloud Functions.
## Try it out
To see the live workkng demo, navigate to [https://nlu-web.mybluemix.net](https://nlu-web.mybluemix.net)
## Prerequisities
- Required [IBM Cloud account](https://www.bluemix.net). Lite / Free tier is sufficient.
- A [Watson Natural Language Understanding](https://console.bluemix.net/catalog/services/natural-language-understanding) service instance on IBM Cloud.
## Setup
### Server
1. Login and set your target organization and space
```shell
bx login
bx target -o -s
```
2. Apply your Watson Natural Language Understanding service credentials
```
vi server/index.js
```
Note: `:wq!` will save an exit from `vi`
3. Replace line `` and `` with your service credentials
```javascript
const nlu = new NaturalLanguageUnderstandingV1({
username: '',
password: '',
version_date: '2017-02-27',
})
```
4. Deploy the OpenWhisk action (IBM Cloud Function)
```shell
bx wsk action update /_/demo/nlu_analyze index.js --web true --kind nodejs:8
```
### Client
1. Change the endpoint url to reference your new action's endpoint
```shell
vi src/config.js
```
```javascript
export const nluNewsApiRoot = 'https://openwhisk.ng.bluemix.net/api/v1/web/_/demo'
```
2. Install dependencies
```shell
npm install
```
## Run (locally)
1. Install dependencies
```shell
npm start
```
2. Navigate to [http://localhost:8080](http://localhost:8080)
## Deploy (IBM Cloud)
