A multi-layered approach to surfacing and analysing organisational narratives : increasing representational authenticity
This paper presents an integrated, multi-layered approach to narrative inquiry, elucidating the evolving story of organisational culture through its members and their physical, textual, linguistic and visual dialogue. A dynamic joint venture scenario within the UK hi-technology sector was explored to advance understanding of the impact of transformation level change, specifically its influence on shared belief systems, values and behavioural norms. STRIKE â STructured Interpretation of the Knowledge Environment is introduced as an innovative technique to support narrative inquiry, providing a structured, unobtrusive framework to observe, record, evaluate and articulate the organisational setting. A manifestation of narrative in physical dialogue is illuminated from which the underlying emotional narrative can be surfaced.
Focus groups were conducted alongside STRIKE to acquire a first order retrospective and contemporaneous narrative of culture and enable cross-method triangulation. Attention was given to non-verbal signals such as Chronemic, Paralinguistic, Kinesic and Proxemic communication and participants were also afforded opportunities to develop creative output in order to optimise engagement. Photography was employed to enrich STRIKE observation and document focus group output, affording high evidential value whilst providing a frame of reference for reflection.
These tools enable a multiplicity of perspectives on narrative as part of methological bricolage. Rich, nuanced and multi-textured understanding is developed, as well as the identification of connections, timbre and subjugated knowledge. A highly emotional and nostalgic context was established with actorsâ sense of self strongly aligned with the pre-joint venture organisation and its brand values, norms and expectations. Credibility and authenticity of findings is enhanced through data triangulation indicating traceability across methods, and from the contextual preservation attained through STRIKE.
The multi-layered approach presented can facilitate researcher reflexivity and sense-making, while for the audience, it may be employed to help communicate and connect research findings. In particular, STRIKE demonstrates utility, quality and efficacy as a design artefact following ex-post evaluation. This systematic method of narrative inquiry is suitable for standardisation and alongside a diagnostic/prescriptive capacity, affords both researcher and practictioner value in its application
SentimentGPT: Exploiting GPT for Advanced Sentiment Analysis and its Departure from Current Machine Learning
This study presents a thorough examination of various Generative Pretrained
Transformer (GPT) methodologies in sentiment analysis, specifically in the
context of Task 4 on the SemEval 2017 dataset. Three primary strategies are
employed: 1) prompt engineering using the advanced GPT-3.5 Turbo, 2)
fine-tuning GPT models, and 3) an inventive approach to embedding
classification. The research yields detailed comparative insights among these
strategies and individual GPT models, revealing their unique strengths and
potential limitations. Additionally, the study compares these GPT-based
methodologies with other current, high-performing models previously used with
the same dataset. The results illustrate the significant superiority of the GPT
approaches in terms of predictive performance, more than 22\% in F1-score
compared to the state-of-the-art. Further, the paper sheds light on common
challenges in sentiment analysis tasks, such as understanding context and
detecting sarcasm. It underscores the enhanced capabilities of the GPT models
to effectively handle these complexities. Taken together, these findings
highlight the promising potential of GPT models in sentiment analysis, setting
the stage for future research in this field. The code can be found at

âOught Implies Canâ: Not So Pragmatic After All
Those who want to deny the âought implies canâ principle often turn to weakened views to explain âought implies canâ phenomena. The two most common versions of such views are that âoughtâ presupposes âcanâ, and that âoughtâ conversationally implicates âcanâ. This paper will reject both views, and in doing so, present a case against any pragmatic view of âought implies canâ. Unlike much of the literature, I won't rely on counterexamples, but instead will argue that each of these views fails on its own terms. âOughtâ and âcanâ do not obey the negation test for presupposition, and they do not obey the calculability or the cancelability tests for conversational implicature. I diagnose these failures as partly a result of the importance of the contrapositive of âought implies canâ. I end with a final argument emphasizing the role the principle plays in moral thinking, and the fact that no pragmatic account can do it justice

Sentiment Classification Using Negation as a Proxy for Negative Sentiment
We explore the relationship between negated text and neg- ative sentiment in the task of sentiment classiïŹcation. We propose a novel adjustment factor based on negation occur- rences as a proxy for negative sentiment that can be applied to lexicon-based classiïŹers equipped with a negation detec- tion pre-processing step. We performed an experiment on a multi-domain customer reviews dataset obtaining accuracy improvements over a baseline, and we further improved our results using out-of-domain data to calibrate the adjustment factor. We see future work possibilities in exploring nega- tion detection reïŹnements, and expanding the experiment to a broader spectrum of opinionated discourse, beyond that of customer reviews
Inferring Interpersonal Relations in Narrative Summaries
Characterizing relationships between people is fundamental for the
understanding of narratives. In this work, we address the problem of inferring
the polarity of relationships between people in narrative summaries. We
formulate the problem as a joint structured prediction for each narrative, and
present a model that combines evidence from linguistic and semantic features,
as well as features based on the structure of the social community in the text.
We also provide a clustering-based approach that can exploit regularities in
narrative types. e.g., learn an affinity for love-triangles in romantic
stories. On a dataset of movie summaries from Wikipedia, our structured models
provide more than a 30% error-reduction over a competitive baseline that
considers pairs of characters in isolation
