Bert-base Turkish Sentiment Model

https://huggingface.co/savasy/bert-base-turkish-sentiment-cased

This model is used for Sentiment Analysis, which is based on BERTurk for Turkish Language https://huggingface.co/dbmdz/bert-base-turkish-cased

Dataset

The dataset is taken from the studies [2] and [3], and merged.

  • The study [2] gathered movie and product reviews. The products are book, DVD, electronics, and kitchen. The movie dataset is taken from a cinema Web page (Beyazperde) with 5331 positive and 5331 negative sentences. Reviews in the Web page are marked in scale from 0 to 5 by the users who made the reviews. The study considered a review sentiment positive if the rating is equal to or bigger than 4, and negative if it is less or equal to 2. They also built Turkish product review dataset from an online retailer Web page. They constructed benchmark dataset consisting of reviews regarding some products (book, DVD, etc.). Likewise, reviews are marked in the range from 1 to 5, and majority class of reviews are 5. Each category has 700 positive and 700 negative reviews in which average rating of negative reviews is 2.27 and of positive reviews is 4.5. This dataset is also used by the study [1].

  • The study [3] collected tweet dataset. They proposed a new approach for automatically classifying the sentiment of microblog messages. The proposed approach is based on utilizing robust feature representation and fusion.

from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline

model = AutoModelForSequenceClassification.from_pretrained("savasy/bert-base-turkish-sentiment-cased")
tokenizer = AutoTokenizer.from_pretrained("savasy/bert-base-turkish-sentiment-cased")

# False

Test

Data

Suppose your file has lots of lines of comment and label (1 or 0) at the end (tab seperated)

comment1 ... \t label
comment2 ... \t label
...

Code

from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline

model = AutoModelForSequenceClassification.from_pretrained("savasy/bert-base-turkish-sentiment-cased")
tokenizer = AutoTokenizer.from_pretrained("savasy/bert-base-turkish-sentiment-cased")
sa = pipeline("sentiment-analysis", tokenizer=tokenizer, model=model)

input_file = "/path/to/your/file/yourfile.tsv"

i, crr = 0, 0
for line in open(input_file):
    lines = line.strip().split("\t")
    if len(lines) == 2:

        i = i + 1
        if i%100 == 0:
            print(i)

        pred = sa(lines[0])
        pred = pred[0]["label"].split("_")[1]

        if pred == lines[1]:
        crr = crr + 1

print(crr, i, crr/i)
