Natural language processing

Beginning with the basic issues of NLP, this chapter aims to chart the major research activities in this area since the last ARIST Chapter in 1996 (Haas, 1996), including: (i) natural language text processing systems - text summarization, information extraction, information retrieval, etc., including domain-specific applications; (ii) natural language interfaces; (iii) NLP in the context of www and digital libraries ; and (iv) evaluation of NLP systems

Learning from a Generative AI Predecessor -- The Many Motivations for Interacting with Conversational Agents

For generative AI to succeed, how engaging a conversationalist must it be? For almost sixty years, some conversational agents have responded to any question or comment to keep a conversation going. In recent years, several utilized machine learning or sophisticated language processing, such as Tay, Xiaoice, Zo, Hugging Face, Kuki, and Replika. Unlike generative AI, they focused on engagement, not expertise. Millions of people were motivated to engage with them. What were the attractions? Will generative AI do better if it is equally engaging, or should it be less engaging? Prior to the emergence of generative AI, we conducted a large-scale quantitative and qualitative analysis to learn what motivated millions of people to engage with one such 'virtual companion,' Microsoft's Zo. We examined the complete chat logs of 2000 anonymized people. We identified over a dozen motivations that people had for interacting with this software. Designers learned different ways to increase engagement. Generative conversational AI does not yet have a clear revenue model to address its high cost. It might benefit from being more engaging, even as it supports productivity and creativity. Our study and analysis point to opportunities and challenges.Comment: 26 pages, 18 figures, 2 table

Two conceptions of the mind

Since the cognitive revolution during the last century the mind has been conceived of as being computer-like. Like a computer, the brain was assumed to be a physical structure (hardware) upon which a computational mind (software) was built. The mind was seen as a collection of independent programs which each have their own specific tasks, or modules. These modules took sensory input data and transduced it into language-like representations which were used in mental computations. Recently, a new conception of the mind has developed, grounded cognition. According to this model, sensory stimulus is saved in the original format in which it was received and recalled using association mechanisms. Rather than representations being language-like they are instead multimodal. The manipulation of these multimodal representations requires processing distributed throughout the brain. A new holistic model for mental architecture has developed in which the concerted activity of the brain\u27s modal systems produces functional systems which are intimately codependent with one another. The purpose of this thesis is to explore both the modular and multimodal theories of mental architecture. Each will be described in detail along with their supporting paradigms, cognitivism and grounded cognition. After my expositions I will offer support for my own position regarding these two theories before suggesting avenues for future research

"Monsters on the Brain: An Evolutionary Epistemology of Horror"

The article discusses the evolutionary development of horror and fear in animals and humans, including in regard to cognition and physiological aspects of the brain. An overview of the social aspects of emotions, including the role that emotions play in interpersonal relations and the role that empathy plays in humans' ethics, is provided. An overview of the psychological aspects of monsters, including humans' simultaneous repulsion and interest in horror films that depict monsters, is also provided

The Logical Structure of Consciousness

It is my contention that the table of intentionality (rationality, consciousness, mind, thought, language, personality etc.) that features prominently here describes more or less accurately, or at least serves as an heuristic for, how we think and behave, and so it encompasses not merely philosophy and psychology, but everything else (history, literature, mathematics, politics etc.). Note especially that intentionality and rationality as I (along with Searle, Wittgenstein and others) view it, includes both conscious deliberative linguistic System 2 and unconscious automated prelinguistic System 1 actions or reflexes. I provide a critical survey of some of the major findings of two of the most eminent students of behavior of modern times, Ludwig Wittgenstein and John Searle, on the logical structure of intentionality (mind, language, consciousness, behavior), taking as my starting point Wittgenstein’s fundamental discovery –that all truly ‘philosophical’ problems are the same—confusions about how to use language in a particular context, and so all solutions are the same—looking at how language can be used in the context at issue so that its truth conditions (Conditions of Satisfaction or COS) are clear. The basic problem is that one can say anything but one cannot mean (state clear COS for) any arbitrary utterance and meaning is only possible in a very specific context. I analyze various writings by and about them from the modern perspective of the two systems of thought (popularized as ‘thinking fast, thinking slow’), employing a new table of intentionality and new dual systems nomenclature. I show that this is a powerful heuristic for describing behavior. Thus, all behavior is intimately connected if one takes the correct viewpoint. The Phenomenological Illusion (oblivion to our automated System 1) is universal and extends not merely throughout philosophy but throughout life. I am sure that Chomsky, Obama, Zuckerberg and the Pope would be incredulous if told that they suffer from the same problem as Hegel, Husserl and Heidegger, (or that that they differ only in degree from drug and sex addicts in being motivated by stimulation of their frontal cortices by the delivery of dopamine (and over 100 other chemicals) via the ventral tegmentum and the nucleus accumbens), but it’s clearly true. While the phenomenologists only wasted a lot of people’s time, they are wasting the earth and their descendant’s future

An overview of parallel distributed processing

Parallel Distributed Processing (PDP), or Connectionism, is a frontier cognitive theory that is currently garnering considerable attention from a variety of fields. Briefly summarized herein are the theoretical foundations of the theory, the key elements observed in creating simulation computer programs, examples of its applications, and some comparisons with other models of cognition. A majority of the information is culled from Rumelhart and McClelland\u27s (1986) two volume introduction to the theory, while some concerns from the field and the theorists\u27 accompanying responses are taken from a 1990 article by Hanson and Burr
