# SVM Model with TF-IDF
This repository provides a pre-trained Support Vector Machine (SVM) model for text classification using Term Frequency-Inverse Document Frequency (TF-IDF). The repository also includes utilities for data preprocessing and feature extraction:

There are two ways to test our model: 
# 1.Colab (can see the test_example.py file for how the Colab looks like)
## Start
<br> Download files ```tfidf.py```, ```svm.py``` and ```data_cleaning.py```.
<br> Upload the files in Colab directly under Files as well as the test data.
<br> Copy all the codes below into Colab.
<br>Before running the code, ensure you have all the required libraries installed:

```python
pip install nltk beautifulsoup4 scikit-learn pandas datasets fsspec huggingface_hub
```

<br> Download necessary NTLK resources for preprocessing. 

```python
import nltk
nltk.download('stopwords')
nltk.download('wordnet')
nltk.download('omw-1.4')
```
<br>Clean the Dataset
```python
from data_cleaning import clean
import pandas as pd
import nltk
nltk.download('stopwords')
```

<br> You can replace with any datasets you want by changing the file name inside ```pd.read_csv()```.
```python

df = pd.read_csv("hf://datasets/CIS5190abcd/headlines_test/test_cleaned_headlines.csv")


cleaned_df = clean(df)

```

- Extract TF-IDF Features
```python
from tfidf import tfidf


X_new_tfidf = tfidf.transform(cleaned_df['title'])

```

- Make Predictions
```python

from svm import svm_model

```



# 2. Termial
## Start:
<br>Open your terminal. 
<br> Clone the repo by using the following command:
```
git clone https://huggingface.co/CIS5190abcd/svm
```
<br> Go to the svm directory using following command:
```
cd svm
```
<br> Run ```ls``` to check the files inside svm folder. Make sure ```tfidf.py```, ```svm.py``` and ```data_cleaning.py``` are existing in this directory. If not, run the folloing commands:
```
git checkout origin/main -- tfidf.py
git checkout origin/main -- svm.py
git checkout origin/main -- data_cleaning.py
```
<br> Rerun ```ls```, double check all the required files（```tfidf.py```, ```svm.py``` and ```data_cleaning.py```） are existing. Should look like this:

<br> keep inside the svm directory until ends. 

## Installation
<br>Before running the code, ensure you have all the required libraries installed:

```python
pip install nltk beautifulsoup4 scikit-learn pandas datasets fsspec huggingface_hub
```
<br> Go to Python which can be opened directly in terminal by typing the following command:
```
python
```
<br> Download necessary NTLK resources for preprocessing. 

```python
import nltk
nltk.download('stopwords')
nltk.download('wordnet')
nltk.download('omw-1.4')
```
<br> After downloading all the required packages, **do not** exit. 


## How to use:
Training a new dataset with existing SVM model, follow the steps below：

- Clean the Dataset
```python
from data_cleaning import clean
import pandas as pd
import nltk
nltk.download('stopwords')
```
<br> You can replace with any datasets you want by changing the file name inside ```pd.read_csv()```.
```python

df = pd.read_csv("hf://datasets/CIS5190abcd/headlines_test/test_cleaned_headlines.csv")


cleaned_df = clean(df)

```

- Extract TF-IDF Features
```python
from tfidf import tfidf


X_new_tfidf = tfidf.transform(cleaned_df['title'])

```

- Make Predictions
```python

from svm import svm_model

```
```exit()``` if you want to leave python.

```cd ..```if you want to exit svm directory.
