semantics analysis

To estimate the relation and interaction between factors of social support and self-acceptance, the gaussian graphical model (GGM) was conducted. The GGM is a probabilistic model that represents dependencies between variables using a graph, which could present the relation between multiple variables (Epskamp et al., 2018b). To further regularize the network structure and provide more convenience for understanding, the extended Bayesian information criterion (EBIC) and graphical least absolute shrinkage and selection operator (LASSO) were utilized (Epskamp and Fried, 2018; Epskamp et al., 2018a).

Moreover, semantic relatedness has been shown either facilitate11,12,13,14,15,16 or impair17,18 episodic memory performance, depending on factors such as recall delay, degree of relatedness within the to-be-learned pairs, and the semantic relatedness of the broader stimulus set15. Episodic experiences can also influence semantic knowledge by integrating new information as learning occurs, or by emphasizing task or context-relevant semantic features in pre-existing semantic space19,20,21. However, further specification of the mechanisms of these putative bidirectional episodic/semantic interactions is needed. Each column corresponds to a media outlet, and each row corresponds to a target word which usually means an entity or concept in the news text. The color bar on the right describes the value range of the bias value, with each interval of the bias value corresponding to a different color. As the bias value changes from negative to positive, the corresponding color changes from purple to yellow.

Accuracy alone, however, can only provide limited insight into exactly how semantic relatedness differentially improves memory for tested and restudied pairs of words. To address this gap, we developed an extension of a multi-arrangement paradigm to simultaneously measure the semantic similarity of sixty words at a time and impute the semantic similarity of words in to-be-learned pairs without them ever being directly measured against one another. In this analysis, we showed that successful learning, especially of related pairs, draws paired words closer together in semantic space more than unsuccessful learning attempts and pairs that did not undergo learning. First, we find that media outlets from different countries tend to form distinct clusters, signifying the regional nature of media bias. On the one hand, most media outlets from the same country tend to appear in a limited number of clusters, which suggests that they share similar event selection bias. On the other hand, as we can see, media outlets in the same cluster mostly come from the same country, indicating that media exhibiting similar event selection bias tends to be from the same country.

In normal tissue ADM and dysplasia are sparse predictions comprised primarily of arbitrary single pixels, and in pancreatitis this is true for just dysplasia. (b) In normal tissues, ADM and dysplasia predictions are negligible, and in pancreatitis there is a significant spike in ADM coverage with negligible dysplasia. Erroneous predictions of ADM and dysplasia in these samples are primarily driven by noise. The quality of the full stained image varies region to region, as some regions have dimmer staining than others. Because of this uneven staining quality, a single global threshold will not accurately represent true positives and negatives because dimmer regions will be neglected. When regions are thresholded independently, the quality of the segmentation masks improves; however, even regional dim spots are still dropped from the segmentations.

Types of transitivity shifts for comparative analysis

You can foun additiona information about ai customer service and artificial intelligence and NLP. As examples, the Resolution Workflow and Scheduling features allow the opening of queries to request the verification of the collected data and assist in scheduling expected visits for participants during the study (although it requires a manual setup for each participant), respectively. The converter supports all common field types, such as text, date, date and time, time, integer, decimal, calculation, single selection, multiple selection, files, and notes. These fields, including the variable name and values assigned to options in single and multiple selections will be converted as-is so that instruments on both systems will have a matching structure.

Restudied pairs were excluded from this analysis as the accuracy of these pairs reflected the ability to correctly type the fully visible target word, rather than memory recall performance. During each of the first two rounds, all 60 pairs were presented on the screen in randomized order, with the text written in capital letters. For each pair, the cue word was presented on the left and the target word on the right. During the first round, participants were asked to make a judgement about how related the cue and the target word pairs were on a scale of 1−4, with 1 meaning “not related” and 4 meaning “very related”. The second round was structured the same as the first, but participants were asked to judge how likely it would be for those two words to appear on the same page of a book or magazine on a scale of 1–4, with 1 meaning “not at all likely” and 4 meaning “very likely”. These judgements allowed for incidental encoding and encouraged the relational processing of the words in each pair.

These potential targets might not be similar to the ground-truth target, but it is important that they are all near-equally similar to the source. If semantic change across languages exhibits shared regularity in directionality, we expect the predictor variables we described to infer or recapitulate the historically attested directions of semantic change across languages substantially better than chance. We are also interested in understanding whether some predictor would dominate in directionality inference over other predictors.

Therefore, researchers consider microstates as “thought atoms,” the basic units constituting emotions and cognition (Lehmann et al., 1998). Normal and abnormal cognitive states may manifest varying patterns in microstate sequences. Among the four microstate classes, the temporal dynamics of Microstate C and D are regarded as potential endophenotypes of SCZ (Chang et al., 2022; Lin et al., 2022; Chen P.-H. et al., 2023).

Using our latent components in our modelling task

To rule out the possibility that the LLMs’ meaningfulness judgment on two-word phrases depended on the meaningfulness of the phrases prior to or following it, we shuffled the order of the phrases ten times and repeated the query for ten iterations. The query inputs were kept the same for different LLMs to ensure a direct comparison. The final meaningfulness judgment for each phrase was the average score across ten iterations. Compared to the human distribution, which reflects “makes sense” and “nonsense” phrases in the bimodal peaks, Gemini-1.0-Pro and GPT-3.5-turbo showed a bias towards rating most phrases as a 2 or 3 (makes some sense, makes a lot of sense; Fig. 1).

The selection of MOX2-5 sensors aligns with the precise objectives of our research, allowing us to contribute in-depth insights into the physiological aspects of physical activity and the potential applications of medical-grade sensor technology in the health monitoring domain. While the initial participant demographics may skew toward a higher number of men, it has also been crucial to recognize that recruitment dynamics, individual preferences, and availability often influence the composition of study samples. Subsequent efforts will be made to actively address the gender balance in future participant recruitment to ensure a more representative dataset. Importantly, the study’s overarching objective remains the investigation of physical activity behaviors within the specified age range, and the inclusion of participants from various genders is vital to achieving a comprehensive understanding of these patterns.

  • We therefore repeated the analyses on the unrelated/related prime group using a baseline of 300 ms before the prime word.
  • Moreover, with the ability to capture the context of user searches, the engine can provide accurate and relevant results.
  • When studying media bias issues, media logic provides a framework for understanding the rules and patterns of media operations, while news evaluation helps identify and analyze potential biases in media reports.
  • For verbs, the analysis is mainly focused on their semantic subsumption since they are the roots of argument structures.
  • Admittedly, the high informativity of the meaning pattern of “internal traits” is also determined by the context.

Thus, semantic interoperability is a critical consideration in information system design13. It is achieved when one system can understand the context and meaning of the information provided by another system14. Research Electronic Data Capture (REDCap)8 and KoBoToolbox9 are two well-known EDC systems. The first one presents a better approach to the whole research life cycle but has significant disadvantages, such as usability issues and the inability to working offline without additional software. The second one delivers a user-friendly interface and natively works offline through a mobile browser but has limited features for data management. Electronic Data Capture (EDC) systems are valuable tools for clinical trials and research to capture data4 and should offer improved data integrity, cost savings, and a shorter time to study database closure5.

To conceptualize the context more pragmatically, the register theory was developed by Halliday and Matthiessen (2004, 2014), Wang et al. (2019). Meaning patterns of the NP de VP construction uncovered in this research reflect the compositionality in terms of the construction grammar. Compositionality highlights the ChatGPT degree of transparency of association between forms of constructs (i.e., specific NPs and VPs in the construction) and meanings (Traugott and Trousdale, 2013). A construct with compositionality in terms of semantics means that the meaning of a construct could be understood if the meanings of each unit are known.

Since datasets were continuous, independent, and had no tied values, after checking the assumption and conditions were met, and since the datasets were small, non-Gaussian, and contained outliers, the non-parametric Mann–Whitney U test was used to access statistical differences in means. Since datasets were small and had outliers, the correlation tests for all models were conducted using Spearman ChatGPT App correlation. At this stage of the tool’s development, no label for fully developed adenocarcinoma features were used, so lesions that have progressed beyond high grade dysplasia would likely be mislabeled as either ADM or “other”. With future work, it should be possible to train models to identify these additional tissue features and predict them accurately alongside the existing models.

Additionally, semantic role labelling focuses on extracting the information structure of a sentence while textual entailment estimates the informational explicitness of a text. Since both methods perform semantic analysis without specifically considering word meaning and textual content, they are more suitable than deep semantic analysis tools for identifying the semantic universals of translated texts as well as distinguishing different language varieties. Having found confirmation in the scalp analysis that there is indeed a difference between abstract and concrete words, we performed source space analysis to obtain the ROIs that would be taken into our model of connectivity analysis in later steps.

2. Inference of source-target mapping of semantic change

The results in Table 1 indicate that there are unequal variances between ES and CT for all indices. Thus, several Mann-Whitney U tests were performed to determine whether there are significant differences between the indices of the two different text types. This section mainly focuses on the discussion of S-universals and presents the results of the comparison between ES and CT. With all the data collected, several statistical tests were conducted on all the indices to explore whether CT exhibit significant semantic differences from ES. Then, a detailed inspection of specific semantic roles was conducted to discuss specific semantic divergences between the two text types. After the semantic roles in each corpus are labelled, textual entailment analysis is then conducted based on the labelling results.

They found syntactic eclectic features of translated texts at the syntactic level, suggesting that translation is the result of the negotiation between the source language and the target language, liable to influences from both directions (Fan & Jiang, 2019). In the current study, such eclectic features are also found at the syntactic-semantic level, indicating that the negotiation in the complex translation process also has an impact on the semantic characteristic of the translated texts. This supports Krüger’s (2014) view that S-universal and T-universal are caused semantics analysis by different factors. One plausible explanation for these findings might be the Hypothesis of Gravitational Pull posited by Halverson (2003, 2017), which assumes that translated language is affected by three types of forces. One force is the “magnetism effect” of the target language that comes from prototypical or highly salient linguistic forms. The second force is the “gravitational pull effect” that comes from the source language, which is the counter force of the magnetism effect that stretches the distance between the translated language and the target language.

As a filmmaker, Wes Anderson’s work functions within the hob smosh French-Arthouse-Americana genre of himself. The Wes Anderson film is one that is riddled with expectations and criteria that are culturally parodied and emulated by amateur film artists. Through sifting through the semantic and syntactic functions of a Wes Anderson film, we can identify his adherence to and subversion of expectations in his work. Genre in Hollywood is driven by box office numbers and a prediction of what trends will encourage moviegoers to return to theaters.

We therefore repeated the analyses on the unrelated/related prime group using a baseline of 300 ms before the prime word. This was possible because the conditions were very similarly matched at target onset when this was done (see the Supplemental Materials for the full results). There were slight differences in the significance of the results found, although importantly, the effect on the N1 and P2 where consistent words first showed a significant difference and then inconsistent words after that remained and the N400 was also significant.

Sentiment analysis

Results show a slow decline in standard deviation from 0.09 to 0.08 up until 85% of the trials are used, after which the standard deviation drops from 0.08 to 0.05, ultimately reaching 0.03 at 95%. As 85% of trials corresponds to ~230 trials, we propose that this be the minimum amount of trials required for a reliable estimation of the autoregressive parameters in our case. The results of this analysis are shown in Table 2, where it can be seen that method A resulted in the 10 ROIs shown and method B was additionally able to replicate ROI 7 and 8.

The data that support the findings of this study are available from the author Barbara Guardabascio upon reasonable request. This refers to the numerical data resulting from the analysis of the news articles and the trained BERT models. However, the authors are not allowed to share the raw news data provided by Telpress International B.V. These data are the property of the company, and the authors have deleted them after the analysis.

In the context of this remarkable growth, as already noted, our target countries contributed more than 80% of the overall output, without exception. This means the other 28 countries, taken altogether, were never able to reach a contribution rate of 20%. Notably, although the other 28 countries’ contribution level has recently increased, the target 13 countries’ research has truly dominated Asian ‘language and linguistics’ research. The remaining sections of this study, therefore, concentrate mainly on the bibliometric properties of these 13 countries’ research; the objective is to comprehend the trends of Asian ‘language and linguistics’ research. Several studies executed bibliometric analyses to elucidate the trends of ‘language and linguistics’ research. Telpress International B.V.—a company that collects online news from multiple web sources, including mainstream media sites and blogs—provided access to online news data.

If this is the case, we are interested in whether these differences can be explained by any of the factors suggested in the literature to impact semantic change. We are interested in whether the factors may be cultural (e.g., taboo, related to cultural practices) or whether they refer to cognitive associations, such as prototypicality (Lakoff, 1987) or primeordiality (Goddard, 2008). We are interested in these factors not only from the perspective of individual lexical meanings or core concept meanings, but also from the perspective of semantic classes. Further, we are interested in whether there is any connection between rates of semantic evolution and effects of frequency (Pagel et al., 2007). Unfortunately, our data is reduced to culture words, and basic vocabulary would have been more appropriate to respond to these research questions. However, basic vocabulary data coded in an appropriate way has not been available to us.
