Final NLP project (University of Guilan)

In this repository, we implemented a Statistical NLP model to predict news agency, news tags, etc as final project of NLP course in university of Guilan.

# Data root path
data_root = 'data'
fars_file = 'farsnews.jsonl'
asriran_file = 'asriran.jsonl'
# Dataset dataframe column names
keys = None

# News headline tags
not_valid_labels = None

# News agencies
news_agencies = None

Importing Data

with open(os.path.join(data_root, asriran_file), encoding='utf-8') as jd:
    asriran = [json.loads(line) for line in jd]
    asriran = pd.DataFrame(asriran)
print('Number of Datapoints: {}'.format(len(asriran)))

Number of Datapoints: 15000

with open(os.path.join(data_root, fars_file), encoding='utf-8') as jd:
    fars = [json.loads(line) for line in jd]
    fars = pd.DataFrame(fars)
print('Number of Datapoints: {}'.format(len(fars)))

Number of Datapoints: 15000

Preprocessing

Finding Valid Labels:

asr_labels = list(set(reduce(np.append, asriran.newsPathLinks.apply(lambda x: tuple(x.keys())))))
fars_labels = list(set(reduce(np.append, fars.newsPathLinks.apply(lambda x: list(x.keys())))))

set((list(asr_labels) + list(fars_labels)))

Some labels are not valid so:

not_valid_labels = [
     'دانلود',
     'ساير حوزه ها',
     'سایر حوزه ها',
     'دیگر رسانه ها',
     'نامشخص',
     'پیامک',
     'صفحه نخست',
     'عصرايران دو',
]
valid_labels = list(filter(lambda x: x not in not_valid_labels, list(set((list(asr_labels) + list(fars_labels))))))

Creating Documents & Labels:

asriran_tags = asriran['tags'].apply(lambda x: ' '.join(list(x.keys())))
fars_tags = fars['tags'].apply(lambda x: ' '.join(list(x.keys())))

title_count = 2
tag_count = 10
documents = np.append(asriran['body'] + ' ' + asriran['title'] * title_count + asriran_tags*tag_count,
                        fars['body'] + ' ' + fars['title'] * title_count + fars_tags*tag_count)
raw_labels = np.append(asriran.newsPathLinks.apply(lambda x: tuple(x.keys())),
                        fars.newsPathLinks.apply(lambda x: tuple(x.keys())))
org_labels = np.append( ['AsrIran'] * len(asriran), ['Fars'] * len(fars)) # For the third task

Removing Documents which are emtpy:

none_zero_docs = list(map(lambda x: len(x) > 1, documents))
documents = documents[none_zero_docs]
raw_labels = cleans_labels(raw_labels[none_zero_docs], valid_labels)
org_labels = org_labels[none_zero_docs]

Duplicating documents for each of their labels:

proc_documents, proc_labels = extend_labels(documents, raw_labels, valid_labels)

Normalizing & Tokenizing & Removing Stopwords Documents:

normalizer = Normalizer()
word_filter = WordFilter()
documents = list(pd.Series(documents).apply(normalizer.normalize).apply(tokenize).apply(word_filter.filter_words))
proc_documents = list(proc_documents.apply(normalizer.normalize).apply(tokenize).apply(word_filter.filter_words))

Replacing words with less than 2 occurances with unknown word

documents = make_unknown(documents)
proc_documents = make_unknown(proc_documents)

created
created

Making documents one hot encoded

label_set, proc_labels = one_hot_encoder(proc_labels)
label_set_th, org_labels = one_hot_encoder(org_labels)

Deviding document to train and test datasets:

x_train, y_train, x_test, y_test = train_test_split(proc_documents , proc_labels, train_size = 0.80, random_state=85)
x_train_th, y_train_th, x_test_th, y_test_th = train_test_split(documents , org_labels, train_size = 0.80, random_state=85)

Creating Model for the First Task

Training:

nb = NaiveBayes()
nb.fit(x_train, y_train)
