Natural Language Processing (NLP) is a subfield of Artificial Intelligence and Linguistics. However, due to significant advancements in the field of computing, NLP has become a discipline considered independently today, making research areas within NLP popular.

Language ability is unique to humans, which is why linguistics holds an important place within Cognitive Sciences. NLP deals with problems related to the generation and understanding of natural languages by computers. If a model of the language can be created in a computer environment, it would be an extremely useful tool for communication.

The main task of NLP is to design and implement computer systems that can analyze, understand, interpret, and generate a natural language. Research areas within NLP include a better understanding of the structure of natural languages, using natural language as an interface between computers and humans, and performing computer-based language translation. All the work done in this field has been developed for English, a valid language in science and business. Directly translating the rules and algorithms used for English into Turkish is not very feasible due to the morphological differences between the languages. Therefore, studies to be conducted for Turkish can only be carried out by Turkish linguists or native or foreign computer engineers who know Turkish very well.

Applications of NLP include word processors, querying databases using natural language instead of SQL and converting these queries into SQL to provide the result to the user, semi-automatic text translation from one language to another, accessing single or multilingual dictionaries, generating sentences and texts in natural language, summarizing texts, speech recognition, and speech synthesis.

Our Natural Language Research group strives to provide solutions to problems with Machine Learning and Deep Learning-based approaches. In addition to applying existing algorithms to current problems, we design and develop projects aimed at academia and industry by developing new algorithms and approaches.

Our Natural Language Processing Research group is in the establishment phase and welcomes researchers and students who want to work on natural language processing and data science. Studies conducted and planned to be conducted will soon be shared here.

Below are details of the studies carried out and completed by the research group. In addition to ongoing master's and doctoral theses, scientific articles, presentations, and project works are actively conducted. Updates will be announced on the research group page as they are completed.
