In the proposed system the environment of an industrial robot is captured through algorithms of machine learning. Thus, objects and human actions are determined. Based on semantic analysis situational knowledge is inferred and dynamic risk assessment as well as robotic behaviour are concluded. Consequently, this provides the foundation for a reactive robot system for achieving efficient and safe human-robot-cooperation.

The information contained in news articles plays a key role on
financial markets. It may describe changes in the fundamentals of a company
or influence the way investors perceive the risk associated with it. This paper
aims at measuring with mathematical means the main underlying semantic
content of news articles, such that it captures information useful to forecast
volatility.

A modified EGARCH model with external factors, obtained from a latent semantic alaysis on news articles, is proposed to measure the impact on volatility induced by the latent semantic content of the textual news data. I find that several semantic dimensions play an important
role in explaining observed volatility, while others are useful to forecast it. It
is likely, that with further research, a model based on semantic content could
greatly improve our understanding of the market’s response to news releases.

"For nearly half a century formal semantics has been a prominent area in linguistic theory, developed in a fruitful collaboration among linguists, logicians and philosophers. Formal semantics is sometimes regarded with reluctance (even dreaded) due to its mathematical precision and the apparent complexity of its symbolism. This textbook —the first one of this scope in French— provides a relaxed self-contained introduction to the domain, allowing the reader autonomous progressive study from the basic central concepts to significant innovations that have shaped the domain since Montague’s seminal work. Through its chapters, the book provides acquaintance with elements of scientific methodology generally used in formal semantics. The six chapters, completed with solved exercises, gradually move from basic notions in logic and model-theoretic semantics, to quantification, temporal and modal logic, intensionality, and typed λ-calculus, culminating in compositional semantic analysis at the syntax-semantics interface. This introduction will be supplemented with a second volume that would focus on applications and advances in the field which extend the scope of the formalism.The book is intended for linguistics undergraduate and postgraduate students and researchers wishing to improve their skills in formal semantics, as well as for students and researchers of other domains, such as philosophy, logic, or computational science."

This book employs cognitive linguistics to determine the foundational elements of the ancient Israelites' concept of teaching as reflected in the text of the Hebrew Bible and Ben Sira. It analyzes four prominent lexemes that comprise a lexical set referring to the act of teaching: ירה-H, למד-D, ידע-H, and יסר-D. The study concludes that, in its most basic form, the concept of teaching in ancient Israel was that a teacher creates the conditions in which learning can occur. The methodology employed in this project is built on a premise of cognitive studies, namely, that because teaching is a universal human activity, there is a universal concept of teaching: one person A recognizes that another person B lacks knowledge, belief, skills, and the like (or has incomplete or distorted knowledge, etc.), and person A attempts to bring about a changed state of knowledge, belief, or skill in person B. This universal concept provides the starting place for understanding the concept of teaching that Biblical Hebrew reflects, and it also forms the conceptual base against which the individual lexemes are profiled. The study incorporates a micro-level analysis and a macro-level analysis. At the micro-level, each lexeme is examined with respect to its linguistic forms (the linguistic analysis) and the contexts in which the lexeme occurs (the conceptual analysis). The linguistic analysis considers the clausal constructions of each instantiation and determines what transitivity, ditransitivity, or intransitivity contributes to the meaning. Collocations of the lexeme, including prepositional phrases, adverbial adjuncts, and parallel verbs, are evaluated for their contribution to meaning. The conceptual analysis of each lexeme identifies the meaning potential of each word, as well as what aspect of the meaning potential each instantiation activates. The study then determines the lexeme's prototypical meaning, which is profiled on the base of the universal concept of teaching. This step of profiling represents an important adaptation of the cognitive linguistics tool of profiling to meet the special requirements of working with ancient texts in that it profiles prototype meanings, not instantiations. In the macro-analysis, the data of all four lexemes in the lexical set are synthesized. The relationships among the lexemes are assessed in order to identify the basic level lexeme and consider whether the lexemes form a folk taxonomy. Finally, the profiles of the four prototype meanings are collated and compared in order to describe the ancient Israelite concept of teaching. The study finds that the basic level item of the lexical set is למד-D based on frequency of use and distribution. In its prototypical definition, למד-D means to intentionally put another person in a state in which s/he can acquire a skill or expertise through experience and practice. In contrast to this sustained kind of teaching, the prototypical meaning of ירה-H is situational in nature: a person of authority or expertise gives specific, situational instruction to someone who lacks knowledge about what to do. The lexemes יסר-D and ידע-H represent the most restricted and the most expansive lexemes, respectively: the prototypical meaning of יסר-D is to attempt to bring about changed behavior in another person through verbal or physical means, often to the point of causing pain; the prototypical meaning of ידע-H is that a person of authority causes another person to be in a state of knowing something from the divine realm or related to experiences with the divine realm. The study determines that while the four lexemes of the Biblical Hebrew lexical set "to teach" have significant semantic overlap, they cannot be construed in a folk taxonomy because the words are not related in a hierarchical way.

The current Special Issue launched with the aim of further enlightening important CH areas, inviting researchers to submit original/featured multidisciplinary research works related to heritage crowdsourcing, documentation, management, authoring, storytelling, and dissemination. Audience engagement is considered very important at both sites of the CH production–consumption chain (i.e., push and pull ends). At the same time, sustainability factors are placed at the center of the envisioned analysis. A total of eleven (11) contributions were finally published within this Special Issue, enlightening various aspects of contemporary heritage strategies placed in today’s ubiquitous society. The finally published papers are related but not limited to the following multidisciplinary topics:Digital storytelling for cultural heritage;Audience engagement in cultural heritage;Sustainability impact indicators of cultural heritage;Cultural heritage digitization, organization, and management;Collaborative cultural heritage archiving, dissemination, and management;Cultural heritage communication and education for sustainable development;Semantic services of cultural heritage;Big data of cultural heritage;Smart systems for Historical cities – smart cities;Smart systems for cultural heritage sustainability.
