Approaches in Visual Analytics have so far been developed for a wide array of research areas, mainly with a focus on industrial or business applications. The field of linguistics, however, has only marginally incorporated visualizations in its research, e.g. using simple tree representations, attribute-value matrices or network analyses. This paper suggests a new interesting field of applicatio...

The article analyzes the linguistic nature of some nuclear lexemes (power, control, authority, influence) verbalizing the basic concept of the English-language political discourse – the concept of “Power”. The paper reveals the structure of the concept, its conceptual features, as well as the main characteristics of the concept representatives at the language and functional levels.

Most recent studies on emotion analysis and detection focus on how writers express their emotions through textual information. In this paper, we model emotion generation on the Plurk microblogging platform from both writer and reader perspectives. Support Vector Machine (SVM)-based classifiers are used for emotion prediction. To better model emotion generation on such a social network, three ty...

Social media platforms have opened new dimensions within the information retrieval domain leading to a novel concept known as Social Information Retrieval. We argue that the concept of Social Information Retrieval can be extended by augmenting the huge amount of content on the traditional Web with the ever-growing rich Social Web content to increase the information richness of today’s search en...

Over the last decade technological advances have been made which enable us to envision real-world applications of speech technologies. It is possible to foresee applications where the spoken query is to be recognized without even prior knowledge of the language being spoken, for example, information centers in public places such as train stations and airports. Other applications may require acc...

This paper presents a Non-Uniform Units selection-based TextTo-Speech synthesizer. Nowadays, systems use prosodic models that do not allow the prosody to vary as far as we should hope, involving a listening comfort degradation. Our system has the advantage to avoid the using of prosodic model. Speech units selection builds its features set exclusively from the linguistic information generated b...

We present an automated method for estimating the difficulty of spoken texts for use in generating items that assess non-native learners’ listening proficiency. We collected information on the perceived difficulty of listening to various English monologue speech samples using a Likert-scale questionnaire distributed to 15 non-native English learners. We averaged the overall rating provided by t...

In the last decades, a wide range of automatic metrics that use linguistic knowledge has been developed. Some of them are based on lexical information, such as METEOR; others rely on the use of syntax, either using constituent or dependency analysis; and others use semantic information, such as Named Entities and semantic roles. All these metrics work at a specific linguistic level, but some re...

Linguistic labels affect inductive generalization; however, the mechanism underlying these effects remains unclear. According to one similarity-based model, SINC (similarity, induction, naming, and categorization), early in development labels are features of objects contributing to the overall similarity of compared entities, with early induction being similarity based. If this is the case, the...
