One of the main advantages of corpora is that we know exactly the domain of texts from which the corpus data is derived, something that we cannot track from current large language models underlying applications like ChatGPT. We know the texts that make up large general corpora such as BNC2014 and BAWE, and can even extract full texts from these corpora if needed. Corpora also allow for more nuanced analysis of language patterns, including the statistics behind multi-word units and collocations, which can be difficult for GenAI to handle. However, it is important to note that GenAI has its own strengths in advancing our understanding of language-in-use that corpora, to date, have struggled with. We therefore argue that by combining corpus and GenAI approaches, language learners can gain a more comprehensive understanding of how language works in different contexts than is currently possible using only a single approach.</p></div>","PeriodicalId":72254,"journal":{"name":"Applied Corpus Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49320227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has long been known that semantic coherence of speech is altered in AD, but only recently have computational tools been developed that allow for cohesion indices to be computed in an automated fashion on larger data sets. To that end, this study examined semantic coherence in persons with AD and healthy controls. Speech transcripts from 81 individuals with probable AD (Mage = 72.7 years, SD = 8.80, 70.4% female) and 61 healthy controls (Mage = 63.9 years, SD = 8.52, 62.3% female) from DementiaBank were analyzed. Machine learning analyses of coherence were conducted, and models evaluated for classification accuracy (i.e., AD vs controls) as well as ROC-AUC. Relationships between coherence indices and MMSE performance were also quantified. Though no significant group differences emerged in local semantic coherence among adjacent words, persons with AD produced less globally coherent speech relative to healthy controls. Furthermore, global coherence indices predicted AD diagnoses with accuracy between 75% and 78% and were significantly associated with MMSE scores. These findings suggest that automated measures of global coherence can distinguish individuals with AD from healthy controls, which may point to eventual diagnostic utility in clinical settings.</p></div>","PeriodicalId":72254,"journal":{"name":"Applied Corpus Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10354704/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9857433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key means of achieving these changes is through the use of directive speech acts, yet this area is currently under-researched. This study investigates the use of directives in the 2020 COVID-19 briefings of four leaders of English-speaking nations, Jacinda Adern, Boris Johnson, Scott Morrison, and Nicola Sturgeon. We developed a classification system including 16 directive types and used this to compare directive use across these four leaders, examining directness and forcefulness of directive use. The analysis finds Sturgeon to be the most prolific directive user and also to have the highest reliance on imperatives. Johnson, meanwhile, has a preference for directives involving modal verbs, particularly with first- and second-person pronouns. In contrast, Ardern and Morrison show a higher use of indirect directives, normally thought to be a less effective strategy. While Ardern often combines this strategy with judicious use of imperatives, this is not seen in Morrison's COVID-19 briefings. These findings tend to confirm earlier, more impressionistic evaluations of the communication styles of these leaders but also suggest other avenues for research on directive use. We conclude with implications for political crisis communication and analysis of directives in crisis communication.</p></div>","PeriodicalId":72254,"journal":{"name":"Applied Corpus Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42589208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present the Multimodal Corpus Analysis Tool which uses sets of categories, such as dominant colors and object location, to analyze a corpus of online advertisements. The 12 categories are based on both multimodal theory and advertising theory, and the tool produces frequency counts of codes and likelihood of co-occurrence of two codes using observed-to-expected ratio. We illustrate the use of the tool through three case studies. First, examining the left and right positioning of verbal content and images in horizontal adverts, we find that there is a general preference for language left – picture right adverts, a finding potentially questioning currently accepted theories of information value in multimodal texts. Second, examining color schemes in adverts, we find that most use of dominant colors reflects accepted meanings in advice on multimodal text design, except for blue which is associated with storge love. For brightness, colorfulness and contrast, there are differences between adverts for everyday products and adverts for services and expensive products. Third, focusing on the call to action phrases in the adverts, there are differences in the use of the two most common forms (<em>shop now</em> and <em>learn more</em>) in adverts for products and services. These cases illustrate the potential benefits of developing and using multimodal corpus tools.</p></div>","PeriodicalId":72254,"journal":{"name":"Applied Corpus Linguistics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47829695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
