# Installation instructions

We use software by the [Nordlys][] group.
The installation instructions are [here](http://nordlys.readthedocs.io/en/latest/installation.html).

For now, we don't work on the full dataset so we use step 3.1B, **not** 3.1A.

Concretely, the following needs to be done:

```bash
# Requirements
apt install mongodb
service mongodb start

# Nordlys repo
git clone https://github.com/iai-group/nordlys.git
cd nordlys

# Install python code
pip install -r requirements.txt

# Load data
./scripts/load_mongo_dumps.sh
```

If you get encoding errors, you may need to change `python`  to `python3` in
the scripts in `./scripts`.

Now we need elasticsearch and build the index:

```bash
wget -qO- https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.4/elasticsearch-2.3.4.tar.gz | tar xzv
cd elasticsearch/bin
./elasticsearch
```

And in an other shell:

```bash
./scripts/build_dbpedia_index.sh
```

However, that currently only adds 97 documents which does not seem reasonable.
