# Recipes Dataset
|
|
|
|
RecipeNLG dataset is available for download [here](https://recipenlg.cs.put.poznan.pl/dataset). It contains 2.2 million recipes. The size is slightly less than 1 GB.
|
|
|
|
## Download and Unpack the Dataset
|
|
|
|
1. Go to the download page [https://recipenlg.cs.put.poznan.pl/dataset](https://recipenlg.cs.put.poznan.pl/dataset).
|
|
1. Accept Terms and Conditions and download zip file.
|
|
1. Unpack the zip file with `unzip`. You will get the `full_dataset.csv` file.
|
|
|
|
## Create a Table
|
|
|
|
Run clickhouse-client and execute the following CREATE query:
|
|
|
|
``` sql
|
|
CREATE TABLE recipes
|
|
(
|
|
title String,
|
|
ingredients Array(String),
|
|
directions Array(String),
|
|
link String,
|
|
source LowCardinality(String),
|
|
NER Array(String)
|
|
) ENGINE = MergeTree ORDER BY title;
|
|
```
|
|
|
|
## Insert the Data
|
|
|
|
Run the following command:
|
|
|
|
``` bash
|
|
clickhouse-client --query "
|
|
INSERT INTO recipes
|
|
SELECT
|
|
title,
|
|
JSONExtract(ingredients, 'Array(String)'),
|
|
JSONExtract(directions, 'Array(String)'),
|
|
link,
|
|
source,
|
|
JSONExtract(NER, 'Array(String)')
|
|
FROM input('num UInt32, title String, ingredients String, directions String, link String, source LowCardinality(String), NER String')
|
|
FORMAT CSVWithNames
|
|
" --input_format_with_names_use_header 0 --format_csv_allow_single_quote 0 --input_format_allow_errors_num 10 < full_dataset.csv
|
|
```
|
|
|
|
This is a showcase how to parse custom CSV, as it requires multiple tunes.
|
|
|
|
Explanation:
|
|
- The dataset is in CSV format, but it requires some preprocessing on insertion; we use table function [input](../../sql-reference/table-functions/input.md) to perform preprocessing;
|
|
- The structure of CSV file is specified in the argument of the table function `input`;
|
|
- The field `num` (row number) is unneeded - we parse it from file and ignore;
|
|
- We use `FORMAT CSVWithNames` but the header in CSV will be ignored (by command line parameter `--input_format_with_names_use_header 0`), because the header does not contain the name for the first field;
|
|
- File is using only double quotes to enclose CSV strings; some strings are not enclosed in double quotes, and single quote must not be parsed as the string enclosing - that's why we also add the `--format_csv_allow_single_quote 0` parameter;
|
|
- Some strings from CSV cannot parse, because they contain `\M/` sequence at the beginning of the value; the only value starting with backslash in CSV can be `\N` that is parsed as SQL NULL. We add `--input_format_allow_errors_num 10` parameter and up to ten malformed records can be skipped;
|
|
- There are arrays for ingredients, directions and NER fields; these arrays are represented in unusual form: they are serialized into string as JSON and then placed in CSV - we parse them as String and then use [JSONExtract](../../sql-reference/functions/json-functions/) function to transform it to Array.
|
|
|
|
## Validate the Inserted Data
|
|
|
|
By checking the row count:
|
|
|
|
Query:
|
|
|
|
``` sql
|
|
SELECT count() FROM recipes;
|
|
```
|
|
|
|
Result:
|
|
|
|
``` text
|
|
┌─count()─┐
|
|
│ 2231141 │
|
|
└─────────┘
|
|
```
|
|
|
|
## Example Queries
|
|
|
|
### Top Components by the Number of Recipes:
|
|
|
|
In this example we learn how to use [arrayJoin](../../sql-reference/functions/array-join/) function to expand an array into a set of rows.
|
|
|
|
Query:
|
|
|
|
``` sql
|
|
SELECT
|
|
arrayJoin(NER) AS k,
|
|
count() AS c
|
|
FROM recipes
|
|
GROUP BY k
|
|
ORDER BY c DESC
|
|
LIMIT 50
|
|
```
