Some problems present in the treatment of opinions are: the use of informal, ironic and sarcastic language, abbreviations, orthographic and typographic mistakes, semantic compositionality, the cultural level and knowledge of language. These problems impose greater difficulty on opinion mining than on text mining in general. Therefore, the aim of our research is to develop computational solution...

Sentiment analysis assumes the task of identifying positive, negative, and neutral thoughts as well as emotional and subjective attitudes of the holder to the target audience, such as products, persons, or topics. Sentiment analysis is emerging as a research field attracting the scientific community. This includes the construction of emotional lexicons as a basis for other sentiment analysis pr...

Motivational Interviewing (MI) is a goal oriented psychotherapy counseling that aims to instill positive change in a client through discussion. Since the discourse is in the form of semi-structured natural conversation, it often involves a variety of non-verbal social and affective behaviors such as laughter. Laughter carries information related to affect, mood and personality and can offer a w...

Room temperature ionic liquids (ILs), especially protic ionic liquids (PILs), are used in many areas of the chemical sciences. Ionicity, the extent of proton transfer, is a key parameter which determines many physicochemical properties and in turn the suitability of PILs for various applications. The spectrum of computational chemistry techniques applied to investigate ionic liquids includes cl...

that the yield of matrix-trapped excess electrons in D 2 0 is larger than in H20 and concluded that D 2 0 is less efficient in the initial electron localization (to yield the solvated electron) than HzO. Our results do not, however, answer the question whether a solvated electron represents the ground state of a cluster anion comprised of as few as 12 water molecules. The reason for this differ...
