# SDG Detector

In 2015, leaders worldwide adopted 17 Sustainable Development Goals (SDGs) with 169 targets to be achieved by 2030 (https://sdgs.un.org). The framework of SDGs serves as a blueprint for shared prosperity for both people and the earth. `SDGdetector` identifies both direct and indirect expressions of SDGs and associated targets in chunks of text. It takes a data frame with a specified column of text to process as inputs, and outputs a data frame with original columns plus matched SDGs and targets.

## Installation

There are two ways to install the **SDGdetector** R package.

### 1. CRAN

**SDGdetector** is now available on
[CRAN](https://CRAN.R-project.org/package=SDGdetector), so you can install it with:

``` r
install.packages("SDGdetector")
```

### 2. GitHub

You can alternatively install the development version of **SDGdetector** from [GitHub](https://github.com/Yingjie4Science/SDGdetector) as follows:

``` r
if (!require("remotes")) {
  install.packages("remotes")
}

remotes::install_github("Yingjie4Science/SDGdetector")
```    
    
## Example Usage

**To detect SDGs from text**
``` r
library(SDGdetector)

### string as input data
text <- 'our goal is to mitigate climate change, end poverty, and reduce inequality globally'
SDGdetector(x = text)

### dataframe as input data
df <- data.frame(col = c(
 'our goal is to end poverty globally', 
 'this product contributes to slowing down climate change'))
SDGdetector(x = df, col = col)
```

**To detect regions/countries in text**
``` r
x = 'China and USA devoted the largest efforts on solar energy'
detect_region(x)
```

**To use specific SDG colors**
``` r
sdg_color(1)
sdg_color(x = 1:17)
```

**To use specific SDG icons**
``` r
sdg_icon(x = 7, res = 300)
```

**To visualize SDG on a bar plot**
``` r
data("sdgstat")
df <- sdgstat

# plot SDG on a bar plot
plot_sdg_bar(data = df, sdg = SDG, value = Value)
```

**To visualize SDG on a map**
```r
# plot SDG by country on a map
plot_sdg_map(data = df, sdg = SDG, value = Value, country = Country, by_sdg = F)
```

## Accuracy Evaluation

This package has achieved high accuracy in detecting SDG-related statements within textual data (> 75%, measured by the alignment between the R package results and four experts' manually-coded results; see this [supplementary document](https://drive.google.com/file/d/14TV54YCQqKwO9j-abC2RuKpy9tKY7jXM/view?usp=sharing) for more information. The data and code for reproducing the performance metrics can be found in this repo under [`./docs/accuracy_evaluation/`](https://github.com/Yingjie4Science/SDGdetector/tree/main/docs/accuracy_evaluation).
