This paper provides an overview into the use of ACT-R as a cognitive architecture in the military. ACT-R stands for Adaptive Control of Thought - Rational. It is a cognitive architecture, a framework for a human like AI program, that models the human mind. In this paper its use will be examined in the military. Through this literary survey an overview will be created of the military’s usage of ACT-R. The overview will answer the questions in which applications the military uses ACT-R and why they use ACT-R. It will bring understanding to the people of how ACT-R is used in the military. It will also give insight into where their tax money is being spent on. For the military an overview will come in handy in case ACT-R gets outdated. They will know what programs will need an update. The overview consists of three parts. A robotics operator manager, a test to determine the value of an officer managing multiple robots. The creation of intelligent tutoring systems for ship navigation and aircraft recognition. A supporting tool for analysts to help determine the value of information.

This paper surveys nine studies that implement aspects of moral reasoning within cognitive architectures (CAs) or CA-inspired frameworks. Its primary aim is to assess the viability of this approach for future research and to clarify the state of the domain. Two research paradigms emerge: (1) modeling human moral reasoning and (2) constructing artificial moral agents. Despite this distinction, all studies face similar challenges: fragmented reuse (each employs a different architecture), limited pre-programmed behaviors, and the absence of standardized benchmarks or metrics. Researchers remain optimistic about the explainability of their systems' behaviors and inner workings, yet often they acknowledge significant scalability and validation hurdles. Overall, CAs currently support only small-scale experiments; substantial further research – both empirical and into the theoretical basis of the field – is needed before these systems can attain real-world relevance.

Heuristic strategies are an integral part of consumer decision-making. Heuristics serve as mental shortcuts that reduce cognitive effort, simplifying consumer decisions. To go from qualitative insights into these heuristics to quantitative data, a cognitive architecture must represent these heuristic strategies to understand consumer behavior better. This study will focus on the cognitive architectures ACT-R and CLARION since there is an interesting distinction in how they structure symbolic (explicit) and subsymbolic (implicit) cognition, influencing how they represent heuristic behavior. Currently, there is no systematic overview and comparison of how ACT-R and CLARION represent heuristics relevant to consumer decision-making. This paper aims to fill this knowledge gap by performing a systematic literature review on papers that contain an ACT-R or CLARION representation of heuristics relevant to consumer decision-making. The review uses four databases for the literature search: Scopus, Web of Science, IEEE Xplore, and ACM Digital Library. In total, 58 records have been screened, and 12 records have been included in the review. The review shows that ACT-R’s strength relies on representing heuristics by sequentially executing rule-based heuristics, while CLARION focuses on representing similarity- based heuristics by using bottom-up activation from its implicit layers. The results show a pattern in which the architectural structure mainly determines which heuristic strategies have been represented.

Episodic memory (EM) -- the capacity to recall past experiences situated in time and context -- is a critical component of intelligent behavior. Although several cognitive architectures (CAs) have incorporated mechanisms inspired by episodic memory, implementations vary widely in structure, mechanisms, and integration with other cognitive functions. While prior work has reviewed episodic memory across a range of architectures in a high-level manner, detailed, structured comparisons among specific systems remain lacking. This study presents a focused comparative analysis of modeling episodic memory in two contrasting cognitive architectures: Soar, a symbolic, rule-based, general-purpose system, and Xapagy, a system designed specifically for narrative reasoning, relying on direct, unprocessed recordings of autobiographical events. By analyzing the representations, structures, and mechanisms of episodic memory in these two systems, this study highlights important design trade-offs and distinct assumptions about the role of episodic memory in cognition and its modeling approaches in CAs.

Strategy games provide a compelling testbed for developing human-like computer agents, with applications that extend beyond gaming into fields requiring adaptive and socially intelligent AI. In these games, players tend to enjoy and engage more deeply with AI opponents that not only provide a challenge but also behave in ways that resemble human thinking and decision-making. However, despite progress in developing such agents, there is still no standard approach for evaluating how human-like these opponents truly are—making it difficult to assess and improve their design. Here I show that strategy game opponents having more human-like game-level playstyles does not necessarily lead to them being more believable (perceived as human-like by human players).

By developing a turn-based strategy game and evaluating Hierarchical Reinforcement Learning (HRL) agents of varying complexity, I assessed both their behavioural similarity to human players and how believable they were perceived to be by human players. This research introduces a new approach for understanding player behaviour using behaviour vectors composed of three high-level metrics—Aggressiveness, Management, and Exploration—consistent with existing literature. These metrics are designed to be broadly applicable across strategy games, enabling consistent comparison between human and AI opponents, as well as across different games and agents. The findings demonstrate that while HRL agents can replicate human-like playstyles without using human training data, players judge human-likeness more on perceived intelligence and fairness. This suggests that creating truly human-like AI opponents requires not just replicating human game-level playstyles, but designing agents that align with players' expectations for intelligent and fair decision-making.

The introduction of Pretrained Language Models (PLMs) has revolutionised the field of Natural Language Processing (NLP) and paved the way for many new, exciting large-scale studies for various areas of research. One such field presents itself in the emerging digital literary corpus that is fanfiction, providing research opportunities within the fields of (NLP), Computational (Socio-) Linguistics, the Social Sciences and Digital Humanities. However, because of the unique linguistic characteristics of this literary domain many modern NLP solutions utilizing PLMs encounter difficulties when applied on fanfiction texts. This paper aims to indicate that the performance of various NLP tasks performed by PLMs on fanfiction texts can be improved by applying Domain Adaptive Pre-Training (DAPT) to PLMs. A case-study is performed to show that the performance of a BERT-based PLM can be improved for the downstream NLP task of Named Entity Recognition (NER) by applying supervised domain specific fine-tuning. While we gain a 6% increase in F1 score performance, we are sceptical about these results due to the limited amount of annotated data available leading to the model overfitting and show a lack of capacity to generalize to unseen data from the CoNLL NER dataset.

This study investigates how genre preferences and sentiment influence fanfiction popularity across multiple languages, focusing on English, Mandarin, Russian, and Spanish datasets. Leveraging advanced natural language processing techniques, including multilingual sentiment analysis, genre classification, and topic modeling, this research explores the interplay between cultural and linguistic factors in storytelling. Preprocessing steps, such as translation and named entity recognition, ensured consistency and reduced noise across the multilingual dataset. Key findings reveal cross-linguistic patterns, such as the popularity of genres like Alter- nate Universe and Romance, alongside cultural distinctions in sentiment and engagement. This work contributes to computational fan studies by demonstrating how linguistic and cultural factors influence storytelling trends and audience preferences in fanfiction.

Fanfiction writers always look for ways to make their stories more engaging. Analyzing what influences the popularity of fanfiction provides insights into readers' preferences and allows writers to tailor to these. This paper attempts to find linear correlations between fanfiction stories and the emotional journey of their characters. It does so by computationally extracting these journeys from 319 Good Omens fanfiction stories, defining and extracting several features from them and using simple linear regression to determine their correlation to fanfiction popularity. Five features were found to have a significant influence on fanfiction popularity. It was also determined that readers prefer characters that have low emotional fluctuations in their behavior.

This paper explores how the portrayal of female characters in fanfiction evolved in response to the #MeToo movement and fourth-wave feminism, with the aim of assessing whether the impact of the awareness of the campaign was broad enough to visibly alter how the average author portrays women in narrative contexts. To analyze these trends, fanfiction data from Archive of Our Own (AO3) spanning 2015–2019 was parsed, and two Natural Language Processing (NLP) pipelines — Word2Vec and GloVe, and BERT — were developed. The study finds that bias scores, aggregated through formulas created to compare gendered associations, show a stronger stereotypization of women before 2017 compared to after. Furthermore, a similar trend is discovered in the representation of women in fanfiction. While the BERT pipeline proved most effective for capturing contextual nuances, it is significantly limited by its reliance on binary labels and computational intensity. This further indicates the need for more inclusive and sustainable methods, making the Word2Vec/GloVe models more appropriate for this task. The paper concludes with recommendations for future work, including broader representation, longer-term analysis, and enhanced detection of evolving language patterns.

This study introduces a new metric for evaluating the disassociation between superstar and non-superstar researchers. Superstar researchers are defined as those in the top 0.1\% by h-index. Leveraging a large dataset, this paper analyzes the data and aims to flatten the discrepancy between superstars and non-superstars, in terms of innovation and popularity. Some authors that publish innovative papers and who haven't collaborated with superstars, tend to be left in the shadows, compared to the ones that have collaborated with superstars from an early stage. The new metric indicates the disassociation between such authors, by factoring in certain parameters that were put into perspective with the help of a Multiple Linear Regression model. The findings reveal significant differences in dissociation scores between researchers and superstar researchers, offering new insights into the dynamics of academic innovation and collaboration. This metric provides a robust tool to identify where an author stands in terms of dissociation and what needs to be done to diminish the discrepancy.

Superstar researchers - those who author research papers which are far more widely cited than average - are generally well-respected within their fields and are frequently sought by new researchers for advice on career development and for collaborations. Though the effect of collaboration with superstar researchers on associated researchers is not well-researched yet, it is believed that collaboration with superstar researchers increases the research output of associated researchers, but may decrease their originality and innovation. This project explores a method of visualizing the career development of researchers associated with superstars. Using a dataset of authors, papers, and paper citations, a graph has been created with papers as edges and nodes as authors to visualize the career development of associate authors after collaboration with a superstar. The utility of this visualization is evaluated using heuristics.

In the scientific community, a few prominent researchers, known as "superstars," receive most of the attention, citations, and resources. However, it is unclear whether they promote true innovation. This study replicates and extends previous work analyzing how superstars influence their collaborators, focusing on the field of computer science. Using the Semantic Scholar Academic Graph dataset, we confirm that while connected researchers in computer science tend to publish more and receive more citations, their ideas are often less innovative. Unlike in the work we replicate, however, we observe this effect even before dissociating the connected researchers from superstars. We also develop a new metric to further clarify the impact of superstars on research diversity. The findings provide insights into the role of superstars in scientific innovation.
