This is a sentence-transformers model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search.

Usage (Sentence-Transformers)

Using this model becomes easy when you have sentence-transformers installed:

pip install -U sentence-transformers

Then you can use the model like this:

from sentence_transformers import SentenceTransformer, util

model = SentenceTransformer('oguuzhansahin/bi-encoder-mnrl-dbmdz-bert-base-turkish-cased-margin_3.0-msmarco-tr-10k')

query = "İstanbul'un nüfusu kaçtır?"

sentences = ["İstanbul'da yaşayan insan sayısı 15 milyonu geçmiştir",
             "Londra'nın nüfusu yaklaşık 9 milyondur.",
             "İstanbul'da hayat çok zor."]

query_embedding = model.encode(query, convert_to_tensor=True)
sentence_embeddings = model.encode(sentences, show_progress_bar=True)

#Compute dot score between query and all document embeddings
scores = util.dot_score(query_embedding, sentence_embeddings)[0].cpu().tolist()

#Combine docs & scores
doc_score_pairs = list(zip(sentences, scores))

#Sort by decreasing score
doc_score_pairs = sorted(doc_score_pairs, key=lambda x: x[1], reverse=True)

#Output passages & scores
for doc, score in doc_score_pairs:
    print(score, doc)

## Expected Output:
400.1816711425781 | İstanbul'da yaşayan insan sayısı 15 milyonu geçmiştir
309.97796630859375 | Londra'nın nüfusu yaklaşık 9 milyondur.
133.04507446289062 | İstanbul'da hayat çok zor.
