Contextualized Topic Models (CTM) are a family of topic models that use pre-trained representations of language (e.g., BERT) to support topic modeling. See the papers for details: Bianchi, F., Terragni, S., & Hovy, D. (2021). Pre-training is a Hot Topic: Contextualized Document Embedd...
在技术领域,Contextualized Topic Models(CTM)通过引入预训练语言模型(如BERT)的上下文嵌入,将传统主题模型中的静态词汇关系升级为动态语义关联,从而提升文本主题分类的准确性和可解释性。 二、主要应用场景 自然语言处理(NLP): CTM项目是典型应用,其利用BERT等模型的动态语义捕捉能力,解决传统主...
ICLR 2019 paper: "textTOvec: DEEP CONTEXTUALIZED NEURAL AUTOREGRESSIVE TOPIC MODELS OF LANGUAGE WITH DISTRIBUTED COMPOSITIONAL PRIOR" About This code consists of the implementations for the model proposed in the paper published at ICLR 2019: "textTOvec: DEEP CONTEXTUALIZED NEURAL AUTOREGRESSIVE TOPIC MO...
Concurrently, contextual embeddings have advanced the state of the art of neural models in general. In this paper, we combine contextualized representations with neural topic models. We tind that our approach produces more meaningful and coherent topics than traditional bag-of-words topic models and ...

models enriched with topic vectors from Latent Dirichlet Allocation (LDA) to represent the candidate phrases and the document. We introduce a scoring mechanism for the phrases using the information obtained from contextualized embeddings and the topic vectors. The salient phrases are extracted using a ...
2.2 Technology Acceptance Models in a Service Context Research on individual acceptance and use of technology is one of the most estab- lished and mature streams of information systems (IS) research (Venkatesh et al. 2016). Accordingly, extant research contains many technology acceptance models, ...
models have been defined as “an approach where clinicians and patients share the best available evidence when faced with the task of making decisions, and where patients are supported to consider options, to achieve informed preferences” (Elwyn et al.,2010). These models are built on the ...
However, despite the well-established interest, the scientific evidence of the impact of serious games remains a debated topic. Here, we present a brief overview of the most recent literature. Our aim is to contribute to that debate with a conceptual proposal based on the issue-attention cycle...
