Sentiment analysis of Turkish political columns with transfer learning

Kaya, Mesut
Sentiment Analysis aims to determine the attitude (sense, emotion, opinion etc.) of a speaker or a writer with respect to a specified topic by automatically classifying a textual data. With the recent explosive growth of the social media content on theWeb, people post reviews of products on merchant sites and express their views about almost anything in their personal blogs, pages at social network sites like Facebook, Twitter, and Blogger. Therefore, sentiment analysis has become a major area of interest in the field of NLP. Up to date, most of the research carried on sentiment analysis was focused on highly subjective English short texts, such as product or movie reviews. In this thesis, sentiment classification is applied on Turkish political columns. Both sentiment analysis on news domain and Turkish language received less attention. Besides, in order to reduce the expense of collection and annotation of the data, Transfer Learning, which is recently adopted to sentiment classification tasks, mechanisms are applied to sentiment analysis of Turkish political columns.


Sentiment analysis in Turkish
Eroğul, Umut; Alpaslan, Ferda Nur; Department of Computer Engineering (2009)
Sentiment analysis is the automatic classification of a text, trying to determine the attitude of the writer with respect to a specific topic. The attitude may be either their judgment or evaluation, their feelings or the intended emotional communication. The recent increase in the use of review sites and blogs, has made a great amount of subjective data available. Nowadays, it is nearly impossible to manually process all the relevant data available, and as a consequence, the importance given to the automat...
Scheme-based Alethic Realism: Agency, the environment, and truthmaking
Baç, Mutlu Murat (Springer Science and Business Media LLC, 2004-05-01)
This paper presents a position called Scheme-based Alethic Realism, which reconciles a realist position on the nature of truth with a pluralistic Kantian perspective that allows for multiple "environments" in which truthmaking relationships are established. We argue that truthmaking functions are constrained by a stable phenomenal world and a stable cognitive architecture. This account takes truth as normatively distinct from epistemic justification while relativizing the truth conditions of our statements ...
Two approaches for collective learning with language games
Gülçehre, Çağlar; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2011)
This thesis presents a defense of the view that externalism cannot be a theoretical basis of a mentalistic causal-explanatory science, even though such a theoretical basis is implicitly or explicitly adopted by many cognitive scientists. Externalism is a theory in philosophy of mind which states that mental properties are relations between the core realizers of an individual’s mental states (such as brain states) and certain things that exist outside those realizers (such as what the content of a mental sta...
Extracting Potentially High Profit Product Feature Groups by Using High Utility Pattern Mining and Aspect Based Sentiment Analysis
Demir, Seyfullah; Alkan, Öznur; Çekinel, Recep Fırat; Karagöz, Pınar (Springer, Cham, 2019-01-01)
As a subproblem of sentiment analysis topic, aspect based sentiment analysis aims to extract distinct opinions for different aspects of a case in a given text. When the case is product review, it is possible to understand reviewer’s opinion on features of the product, rather than the product in general. Then, a product feature can be associated with a sentiment score denoting user satisfaction value by that feature. Modeling features mentioned in a review as items in a transaction may provide better insight...
Word-of-mouth communication in marketing: An exploratory study of motivations behind opinion leadership and opinion seeking
Özdamar Ertekin, Zeynep; Atik, Deniz (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2012-12-1)
With a qualitative approach, this research aims to gain a deeper understanding of the motivations behind both opinion leadership and opinion seeking, in a non-western context. Findings show that no one is exclusively an opinion leader or a seeker and that both opinion leaders and seekers are motivated by deeper psychological needs, which may have a critical role in theory and practice. In addition to previously identified motivations and characteristics of opinion leaders and opinion seekers, new dimensions...
