Another topic that lexical items in the NP slot of the construction considered are about items that are used in the medical field, including such terms as jibing ‘disease’, xibao ‘cell’, jiyin ‘gene’, and bingfazheng ‘syndrome’. Some others such as shijian ‘event’ (denoting a negative sense) and shigu ‘accident’ are clustered with the meaning pattern of “medical names” because of their denoted negative senses. With respect to their covarying collexemes in the VP slot, verbs such as fasheng ‘occur’, chuxian ‘appear’, and cunzai ‘exist’ are significantly preferred by lexical items that realize the meaning pattern of “medical names”.

This again suggests that there is rapid cascaded processing between semantic and orthographic representations. Compared to Midgely et al., it also shows that even though the distractor-target relationships would not have had as much semantic overlap as French–English cognates, early semantic effects can still be obtained if the two stimuli are fully visible and one is a picture and one is a written word. An alternative way word-form has been conceptualised is not based on a lexicon at all.

Media shows diverse biases on different topics

In contrast, the voice of customer is contained in a large number of online reviews at present. Sun et al.4 proposed a dynamical mining method about ever-changing customer requirements. The changing behavior of product attributes was analyzed and an improvement strategy for next-generation product design was shown based on the changing behavior of attributes. Li et al.34 applied general rough set concepts to reveal the association between historical customer needs and design specifications. Jin et al.35 identified the product features and sentiment polarities from big consumer requirements data and employed kalman filter method to forecast the consumer requirement trends. As we know from the “Customer requirements classification” section, customer requirements actually involve multi-domain information and functional customer requirements represent customer intention maximally.

As Zhao (2006, p. 7), argued, “The syntactic differences sometimes make it difficult to get an ideal formal equivalence that carries the equivalent ideational meaning. In such cases, the translation shifts have to be considered to fit the translation well into the target language. A mechanical imitation of the original pattern can only lead to some unnatural translations”. Therefore, when the changes in experiential meaning were caused by the necessary transitivity translation shifts, there is no direct relationship between the transitivity shifts and the deterioration of translation accuracy or quality. Hierarchical cluster analysis is chosen in this study in that it could cluster lexical items that are significantly attracted to the VP slot and the NP slot in the NP de VP construction according to their meanings. In so doing, it will “shed light on the most typical senses of a construction as well as sub-senses instantiated by coherent semantic classes of words occurring in it” (Gries and Stefanowitsch, 2010, p. 73).

In addition to the hyper-parameters setting, an essential factor affecting the efficacy of the topic analysis is the optimal topic number K. At present, some measurable indicators like Perplexity and KL divergence are adopted to measure the optimal topic quantity44. However, Perplexity focuses on the prediction ability of the LDA model for new documents, which often leads to larger topic quantity.

However, traditional studies failed to consider customer requirements representation in the analogical reasoning environment so that it is not effortless to gain latent and innovative customer requirements. Some studies have indicated that accommodating customers into the analogical reasoning environment is essential5,6. In addition to explicit customer requirements, latent customer requirements are extremely crucial to product innovation and success. Understanding and acquisition of latent customer requirements have prominent effect on satisfying customers.

Procedure and task description

In the EU, a central reform has been to mandate earmarked, non-transferable leave for all member countries from 2019. By 2022, all EU member states were required to provide each parent with nine weeks of non-transferable parental leave. The descriptive information and basic demographic information of the participants in the current study are shown in Table 1.

As with the previous tests, the Dot Product formula indicated the best performance for scoring a tweet. Changes in vector dimensionality yielded minimal performance changes, as indicated in Table 5. All formulas performed best with a dimensionality of 150, though the change from the default 100, showed little appreciable difference in the results.

To facilitate effective visualization, we chose GMM to estimate 50 clusters to balance between interpretability and diversity. Figure 6 shows a subset of three clusters, in which we found both the set of source senses and the set of target senses to have clear interpretation. Most of these clusters are for noun senses, as shown by the green and blue clusters.

  • The second clause “则不达” is a material-transformative process type, one that shows “what is happening”, while that process is shifted into the relational process to identify the relationship between “欲速” (Haste) and “则不达” (waste).
  • In the inspection of specific semantic roles, features of agents and discourse markers are found to be evidence for both S-explicitation and T-explicitation, potentially reflecting the role of socio-cultural factors in shaping the uniqueness of syntactic-semantic features of Chinese translations.
  • This includes also in relation to their semantic classification as well as possible cultural connotations, which may affect their change rate.
  • The unrelated/related primes elicited an early effect of priming on the N1 with consistent words.
  • (3) Determining the appropriate length of microstate sequences is imperative for efficient feature extraction and recognition and warrants further investigation.

According to the results in in Tables 10, 11, 12 and 13, the synthetic datasets consistently lead to accuracy improvements. The implementation of the parental leave reform was supported by the major political parties on the left and the centre (e.g., Social Democrats; the Green Left, the Danish Social Liberal Party), along with one major party on the right (Denmark’s Liberal Party). The opposition to the leave reforms, as in other countries such as Norway33 was from the political right (e.g., Conservative People’s Party). The political right’s opposition centred on the negative consequences of earmarked leave for parental choice, and the potential impact on the child, as well as a disagreement with EU imposition of rules in Denmark34. The left’s support of the reform related to achieving gender equality and fathers’ attachment to their children.

In the current study, the reference knowledge base for the textual entailment analysis in this study is WordNet (Miller, 1995) and its multilingual counterpart Open Multilingual WordNet (OMW). Numerous studies have proved that a shallow semantic analysis based on WordNet is adequate for monolingual and multilingual RTE tasks (Castillo, 2011; Ferrández et al., 2006; Reshmi & Shreelekshmi, 2019). Specifically, the current study first divides the sentences in each corpus into different semantic roles.

Target trials were then extracted from − 0.3 to 2 s and the data was re-referenced to the average of both mastoids. The data was then redefined using a baseline from − 200 to 0 ms before the target words. Ten further prime/target pairs were used as fillers at the start of the experiment to ensure participants understood the task. There were also an additional 140 prime-target pairs where the targets were of high frequency. However, since our hypotheses here pertain only to low frequency target words these were excluded from the analyses as were the practice words.

Latent Semantic Analysis (LSA (Deerwester et al. 1990)) is a well-established technique for uncovering the topic-based semantic relationships between text documents and words. By performing truncated singular value decomposition (Truncated SVD (Halko et al. 2011)) on a “document-word” matrix, LSA can effectively capture the topics discussed in a corpus of text documents. This is accomplished by representing documents and words as vectors in a high-dimensional embedding space, where the similarity between vectors reflects the similarity of the topics they represent. In this study, we apply this idea to media bias analysis by likening media and events to documents and words, respectively.

Interventions targeting in improving “SIA” (Self-acceptance) may be effective in helping individuals cultivate social support system and self-acceptance and improve their mental health. Flow network structures and relation between different nodes with age and gender controlled as covariates. (C) The relation between different nodes in the network of POM, social support, and self-acceptance as well as the covariates.

The topography of our effect on the N1 differed somewhat to theirs as our strongest effect was central, unlike their data, making the results hard to compare. Alternatively, the results from our P2 window with the inconsistent words were more similar in that the inconsistent target words proceeding related primes were more positive going ChatGPT App than those that those proceeding unrelated primes. Sereno et al. found a similar pattern in their midline electrodes where highly constrained contexts caused a more positive going effect. Given some of the results from the study were relatively weak, it is important to examine the extent to which analyses assumptions make a difference.

This process could result in meaning extension whereby a word ends up coexpressing both si and sj, or meaning replacement whereby sj takes over the original meaning si. Our analysis does not focus on this distinction and treats these cases equally as instances of semantic shift or meaning change. The first problem we consider is to infer the directionality of historical semantic change between a pair of meanings. Here we adopt a discrete notion of meaning (concordant with the crosslinguistic database of semantic change we analyze) and refer to a meaning equivalently as a sense signified by a word. Several companies are using the sentiment analysis functionality to understand the voice of their customers, extract sentiments and emotions from text, and, in turn, derive actionable data from them. It helps capture the tone of customers when they post reviews and opinions on social media posts or company websites.

While that was consistent with our results in the left anterior temporal lobe, in our study the right anterior temporal lobe seemed to be almost equally involved in sending and receiving information. Schoffelen et al. found that these areas receive information from the inferior frontal cortex, and the superior and middle temporal regions. Even though these results are very much in line with our findings, some differences can be observed given that their stimuli were sentences rather than single words.

Furthermore, along with high model complexity, estimating a large network can also be problematic in terms of the multiple comparisons problem. Therefore, we limited our analysis to the alpha and beta frequency bands during the time windows for which significant differences in activation were observed. In our exploratory analysis, reported in supplementary material section D, we analyzed all consecutive time windows. It is important to note, though, that we do not suggest that there be a simple relationship between difference in activation and difference in connectivity.

For instance, there are many examples in which the interpretation of the data coding may have affected the result. This is particular the case in which a specific stance has been taken on whether a word has been borrowed at an early state alternatively is an early migration word. An example is the word for “donkey” (Cognate ID 56767), Gothic asilus, Old English esol, eosol, Italian asino, Scottish Gaelic asal, Russian osël etc. You can foun additiona information about ai customer service and artificial intelligence and NLP. The conglomerate is often considered to be an early migration word (Kluge, 2002, p. 174–75), which is coded as cognate in our model (Carling, 2019, p. 185–86). The model comes up with a high probability of the meanings “donkey” (1.0), “wild ass” (0.77), and “onager” (0.77) at the root (here defined as “Indo-European,” but rather a Western Indo-European proto-language). The result would have been different if another policy for rendering loans and migration words had been used in the data.

This section focuses on T-universals and presents the results of the comparison between CT and CO. The results of Leneve’s tests in Table 4 exhibit unequal variances between CO and CT for all indices. Mann-Whitney U tests were then conducted to determine whether there were significant differences in indices between two different text types. It appears likely that European leaders can continue to rely on public support for providing weapons to Ukraine, at least for the time being.

Moreover, the combined Generator and Discriminator model was compiled with “ADAM” optimizer and “binary_crossentropy” loss function. The proposed ontology supports personalization, and the OWL representation ChatGPT of the same concept has been captured in Supplementary Material-2 for an individual. For the verification of our ontology model, we use MOX2-5 activity sensor’s observation data.

Thus, it should be theoretically significant to explore the translation of the experiential meaning of the ACPP in Xi’s volumes from the perspective of transitivity translation equivalence and shift. For one thing, lexical items uncovered in this research are representative of those that could fill the VP and the NP slots of the construction. The covarying collexeme analysis highlights lexical items that are significantly attracted to specific constructions, which indicates that these lexical items are the potential to be typical members of the constructions. For another, the meaning patterns of both the NP slot and the VP slot are scientifically and objectively clustered, which is further attributed to the meaning patterns of the NP de VP construction. This research employed cluster analysis which aims at identifying the meaning patterns of the construction. Previous research unveiled possible lexical items that could be the components of the construction, but they did not inform us what the meaning patterns of this construction are because constructions themselves are meaningful (Goldberg, 1995, 2006).

Indeed, since cognitive functions rely on connectivity within large-scale networks41, approaching cognitive processes from the point of view of connectivity can resolve fundamental questions in language processing, such as whether word processing is modular or interactive, parallel or serial37. This can then also help distinguish between feedforward and feedback processes in language42. For example, study43 showed that different frequency bands are involved in the bottom up and top down processing of natural reading states. Other studies have used symmetrical connectivity measures to analyze linguistically complex words and have found a left-lateralized frontotemporal cross-cortical interaction44. The idea that consistent and inconsistent words use different amounts of attention to process also offers an explanation for the lack of differences on the N1 with inconsistent words. In this case, according to CDP, the initially incorrect pronunciation imputed by the sublexical route with inconsistent words would need to be corrected before it could prime the phonological lexicon and cause semantic access, thus reducing any early priming effects.

To accommodate this, we performed bootstrap resampling per subject and condition, and generated 100 resampled datasets, i.e. we repeated the exact same analysis procedure as we did with our original dataset but randomly resampled by replacing the trials within each condition and subject. From this, we calculated the average connectivity over all subjects per bootstrap resampling. The standard deviation over all connectivity pairs in time-frequency showed a maximum of 0.05 (5% of the maximum estimate). A z-score analysis of all bootstrap trial showed that 95.91% of the estimates lie within 2 standard deviations of the mean for each estimate.

The methods proposed here are generalizable to a variety of scenarios and applications. They can be used for a variety of social media platforms and can function as a way for identifying the most relevant material for any search term during natural disasters. These approaches once incorporated into digital apps can be useful for first responders to identify events in real semantics analysis time and devise rescue strategies. Our findings are consistent with existing crosslinguistic work on polysemy, where there are regular patterns in how word relate and express different meanings (Srinivasan and Rabagliati, 2015). However, our current analysis extends this line of research from a synchronic setting to a diachronic view and across many different languages.

It is also a key component of several machine learning tools available today, such as search engines, chatbots, and text analysis software. Despite the general stability of semantic knowledge over the course of one’s lifetime, our results demonstrate that even a brief session of episodic learning can subtly yet systematically re-sculpt semantic space. Together, these changes impart a lingering residue on semantic memory that facilitates later episodic recall. These results are consistent with recent neuropsychological, behavioral, and neuroimaging evidence that the episodic and semantic memory systems may interact through gradients of activation of shared cognitive processes5,6,7.

Lou et al.14 proposed a data-driven approach for customer requirements discernment via Kano model, intuitionistic fuzzy sets theory and electroencephalogram technology. The vagueness of requirements is handled at the semantic expression and neurocognitive level. Shi et al.15 utilized big data of online customer reviews and improved Kano model to classify customer requirements accurately and efficiently. Polynomial modeling and least square methods are adopted to define customer satisfaction and function implementation of customer requirements. Customer requirements are classified based on the slope of the fitted function curves. In addition, customer requirements can generally be divided into dominant and implicit requirements.

Here is a case of process shifts from the material clause to the relational clause. The original Chinese poem means that if one pursues speed blindly, one cannot reach the destination. The second clause “则不达” is a material-transformative process type, one that shows “what is happening”, while that process is shifted into the relational process to identify the relationship between “欲速” (Haste) and “则不达” (waste). This relational-circumstantial-identifying process implies “欲速” (Haste) potentially leads to “则不达” (waste). By doing so, the translator tends to portray the potential bad consequence due to the Identified Participant of “haste”, thus changing the experiential meaning to a large degree. However, it does not necessarily lead to poor quality and accuracy of the translation, for here, the TT still fits the context properly.

Molecular changes may result in inefficient cortical network synchronization, yielding different characteristic for the corresponding microstates. However, empirical studies are needed to gain insight into the connection between molecular alterations and microstates disturbances. The results of ablation experiments in this paper show that the extracted microstate features have a significant positive effect on the recognition of SCZ.

The function descrTable was utilized for the description of the data and the generation of the table. After that, the Cronbach’s α scores of each questionnaire and their subscales were calculated to verify the reliability of the scales used in the current study. These results also urge for caution in the attribution of AGI or similar abilities to LLMs, based only on testing on tasks that are difficult for humans. Seemingly simple language tasks can be difficult for LLMs even when they perform well on complex tasks, which is reminiscent of Moravec’s paradox. The mounting understanding of the impressive abilities as well as limitations of LLMs will be essential in improving these models, and in identifying appropriate use cases. The task, essentially trivial for humans, requires rating meaningfulness of two-word phrases.
