Identifying Insomnia From Social Media Posts: Psycholinguistic Analyses of User Tweets

Background Many people suffer from insomnia, a sleep disorder characterized by difficulty falling and staying asleep during the night. As social media have become a ubiquitous platform to share users’ thoughts, opinions, activities, and preferences with their friends and acquaintances, the shared content across these platforms can be used to diagnose different health problems, including insomnia. Only a few recent studies have examined the prediction of insomnia from Twitter data, and we found research gaps in predicting insomnia from word usage patterns and correlations between users’ insomnia and their Big 5 personality traits as derived from social media interactions. Objective The purpose of this study is to build an insomnia prediction model from users’ psycholinguistic patterns, including the elements of word usage, semantics, and their Big 5 personality traits as derived from tweets. Methods In this paper, we exploited both psycholinguistic and personality traits derived from tweets to identify insomnia patients. First, we built psycholinguistic profiles of the users from their word choices and the semantic relationships between the words of their tweets. We then determined the relationship between a users’ personality traits and insomnia. Finally, we built a double-weighted ensemble classification model to predict insomnia from both psycholinguistic and personality traits as derived from user tweets. Results Our classification model showed strong prediction potential (78.8%) to predict insomnia from tweets. As insomniacs are generally ill-tempered and feel more stress and mental exhaustion, we observed significant correlations of certain word usage patterns among them. They tend to use negative words (eg, “no,” “not,” “never”). Some people frequently use swear words (eg, “damn,” “piss,” “fuck”) with strong temperament. They also use anxious (eg, “worried,” “fearful,” “nervous”) and sad (eg, “crying,” “grief,” “sad”) words in their tweets. We also found that the users with high neuroticism and conscientiousness scores for the Big 5 personality traits likely have strong correlations with insomnia. Additionally, we observed that users with high conscientiousness scores have strong correlations with insomnia patterns, while negative correlation between extraversion and insomnia was also found. Conclusions Our model can help predict insomnia from users’ social media interactions. Thus, incorporating our model into a software system can help family members detect insomnia problems in individuals before they become worse. The software system can also help doctors to diagnose possible insomnia in patients.

Grammatical patterns in the corpus-driven “Lexical Database of Lithuanian”

This paper describes the grammatical patterning of two parts of speech – nouns and adjectives – included in the corpus-driven “Lexical Database of Lithuanian” as a foreign language. The lexical database is a lexicographic application of the Lithuanian Pedagogic Corpus (approx. 620.000 tokens) which was used to develop headword lists and to collect word usage information in the form of corpus patterns. In this project, we adopted a partially automated inductive procedure of Corpus Pattern Analysis for 207 verbs, 386 nouns, 87 adjectives, and 41 adverbs. The detected corpus patterns reflect different meanings of the headword. Each pattern presents information on grammatical, semantic, and lexical levels. Manually selected examples illustrate all pattern components. In this paper, 673 patterns with nouns and 99 patterns with adjectives will be analysed discussing their syntactic behaviour in detail and providing some comments on lexis-grammar interface. The majority of patterns with nouns and adjectives are minimal patterns which include only the closest syntactical partners. This result is influenced by different procedures used to describe patterns with nouns, adjectives, and adverbs and patterns with verbs. Due to rich grammatical information, there are several similar patterns with one main (usually the most frequent) type and its variants. Pattern variants show that the grammatical characteristics of a specific word usage are rather individual.

Love and Death in Latin Elegy

Love and death is a common and shared human experience that many poets of the ancient world explored in their various poetic works. The elegists of Rome famously wrote love poems in which each pined for a specific mistress or lover, and in some of these poems, love and death were simultaneously prominent themes. In this article I examine the relationship between the concepts of love and death in Propertius 4.7, Tibullus 1.3 and Ovid’s Amores 3.9. From this study it is evident that each poet, through means of their own style, depicted the ideal that love had the ability to overcome death. To support my analysis of these texts and the issues surrounding them, I refer to Papanghelis, Hinds and Maltby. While these authors consider many aspects of Proptertius’, Tibullus’ and Ovid’s works, the relationship and connection present between love and death has not been significantly considered. In order to establish each poet’s personal style I begin with a brief overview of elegiac poetry; then, an examination of each poem’s tone, word usage and thematic distinctions. I will begin the discussion with Propertius’ poems; Tibullus’ and Ovid’s poems will then be considered, first separately, and then as a pair. The concepts of love, death and those affected by the death in the poem will be analyzed. In addition, I will consider how love and death interact with each other in the poems. To further supplement the discussion, I will analyze how these three poets’ write in the same genre and about the same topics, but in different contexts and styles. This analysis leads to an understanding that each poet expressed their unique style in their poems, while maintaining a similar theme and genre, that love has the ability to overcome the unavoidable and inevitable force of death.

Pirmais teikums: zinātniskā raksta pieteikums

Tips for writers found in books, articles, blogs, and website forums often focus on the first sentence, engaging the reader to read the entire text. Tips for writing the first sentence are mostly applied to essays, including academic essays. On the other hand, good examples of the first sentence are usually chosen from classical literary works, making it possible to assume that the first sentence has meaning in every text, including a scientific article. The aim is to study and describe the first sentence in articles in various disciplines in the Latvian language to establish the connections between the recommendations on how to start the text and the actual language material. For the aim’s implementation, sentences from 848 scientific articles in Latvian (a total of 9700-word usage) are analyzed. The articles chosen for the study have been published between 2008 and 2018 in three branches and sub-branches of science: medical and health sciences, social sciences, humanities and arts. The main conclusions are as follows: the authors of Latvian scientific articles most often choose in the first sentence 1) to make a statement, 2) indicate the historical or geographical context, 3) define the main term used in the article. This is partly consistent with the suggestions given by writing instructors on the possible attractive content of the first sentence.

The textual similarity of KAM disclosures for Spanish companies

We investigate and document the textual similarity of key audit matter (KAM) disclosures by using KAM items in auditor’s reports of Spanish companies in fiscal years 2017 and 2018. The main objective is to understand how similar KAMs are disclosed from one year to another. Following prior literature, we use the cosine similarity to measure the textual similarity between KAM items in terms of word usage. We classify and analyze KAM items for two consecutive years based on the following three combinations: (1) KAM topic, (2) KAM topic and auditor, and (3) KAM topic, auditor, and industry of the client being audited. The results indicate that auditors from the same accounting firm tend to have a recurring textual similarity under each KAM topic, and such similarity increases for clients within the same industry. The results add empirical evidence to the understanding of the recurring textual similarity of KAM disclosures

Separatism: a cross-linguistic corpus-assisted study of word-meaning development in a time of conflict

This paper considers the role of historical context in initiating shifts in word meaning. The study focusses on two words – the translation equivalents separatist and separatism – in the discourses of Russian and Ukrainian parliamentary debates before and during the Russian–Ukrainian conflict which emerged at the beginning of 2014. The paper employs a cross-linguistic corpus-assisted discourse analysis to investigate the way wider socio-political context affects word usage and meaning. To allow a comparison of discourses around separatism between two parliaments, four corpora were compiled covering the debates in both parliaments before and during the conflict. Keywords, collocations and n-grams were studied and compared, and this was followed by qualitative analysis of concordance lines, co-text and the larger context in which these words occurred. The results show how originally close meanings of translation equivalents began to diverge and manifest noticeable changes in their connotative, affective and, to an extent, denotative meanings at a time of conflict in line with the dominant ideologies of the parliaments as well as the political affiliations of individuals.

THE WAYS OF ENTRY AND FUNCTIONING OF LEXICAL LOANWORDS FOR NAMES OF FOODS AND DRINKS IN THE POEM "ENEYIDA" BY I. KOTLYAREVSKY

The article examines the functioning of lexical loanwords related foods and drinks in the burlesque-travesty poem "Eneyida" by I. Kotlyarevsky, presents etymological analysis of loanwords, studies ways of entry of lexical loanwords, identifies the most used lexemes in order to describe a general picture of enrichment of the lexical stock of the Ukrainian language with words of foreign origin . The purpose is to analyse loanwords related foods and drinks, identifying the most popular loanwords in the «Eneyida» and how they are used in the context of the work. For realization of the purpose , the following tasks were solved: research words of foreign origin from Polish, Latin, Greek, determine ways of entering loanwords related foods and drinks, carry out an etymological analysis of words, note the most popular lexemes in the context of the work. The object of research is lexical loanwords related foods and drinks in the burlesquetravesty poem "Eneyida" by I. Kotlyarevsky and the subject – words of foreign origin from Polish, Latin, Greek. The source base was 15 lexical loanwords related foods and drinks (horilka, syvukha, braha, med, syrivets, kalhanivka, lemishka, lokshyna, oliia, slyvianka, kaviar, chai, chykyldykha, dulivka, sykyzka ) in 65 word usage. The food reflects the national character, the inner culture of the people. The concept "food" is a very important part of the national mentality, thereby the issue of learning the vocabulary related foods and drinks is still relevant. The study found that among the lexemes in the poem "Eneyida" by I. Kotlyarevsky 40% borrowings from Greek and Latin, this is due to the international contacts Ukrainians have with these peoples: trade, travel, art , 20% from Polisch, 20% Lithuanian, 15% Turkish, 5% Chinese. In the poem "Eneyida" fixied 9 direct and 6 indirect borrowing. Among the most popular lexemes are horilka, syvukha, braha. A promising development is the research is lexical loanwords related foods and drinks Ukrainian literature XVIII-XXI century.
