Opis:
Purpose: The study provides a concise overview of the CSR concept in the literature regarding two market’s aspects - quality and marketing. The aim of the study is to analyse to what extent a CSR maps to crisis management phases. Design/methodology/approach: The article entails a literature review of 352 articles published in the years 2006-2021 supported by machine learning. Findings: 15 thematic groups were identified. It is impossible to point to unambiguous thematic trends in relation to the topics in the analysed articles. CSR as a field includes three main elements (economic, environmental, social), but this concept can be considered in many areas and a wide range of organizational activities, which was shown in the article in individual thematic groups. Research limitations/implications: As every literature review serves as a snapshot of a particular period, the results of the study are limited. Future research may also concern the qualitative research (e.g., case-studies in individual companies) and quantitative research (e.g., focusing on specific aspects and/or dedicated samples). Practical implications: The CSR implementation is not a single and short-term organization’s project, but an element of a long-term strategy and market trends. It is an important practical information for all organizations undertaking activities in corporate social responsibility. Social implications: The results of the presented research help the reader to see a broader perspective of CSR activities. Microeconomic activities within the CSR triad influence the macroeconomic scale - the global increase in awareness of business responsibility towards society. Originality/value: This is the first paper containing the literature review results on CSR considering the aspects of quality and marketing. The crisis management perspective was also considered as an issue related to the intensity of organizational activities in CSR.

Opis:
Purpose: An attempt to identify the scope of duties of the business analyst by analyzing job offers from websites. Design/methodology/approach: Job offers were automatically downloaded from five websites. An analysis of text mining of fragments of offers describing the scope of duties was carried out. The analysis of text mining included initial text processing, creation of corpora of analyzed documents, creation of a document-term matrix and the use of classic methods derived from data mining. Findings: The most frequently used words/n-grams and the correlation of selected words/ n-grams with other words/n-grams were presented in the form of drawings. Based on the frequency of words/n-grams and the correlation value, efforts were made to identify the responsibilities of the business analyst. Research limitations/implications: Only offers written in Polish, downloaded from five websites with job offers, which had the phrase “business analyst” in their job title, were analyzed. The data was collected between 13 and 15 April 2020. Practical implications: The method applied can be used by organizations preparing for the profession of a business analyst, to modify and better adapt curricula to the needs of the labor market. Originality/value: Studies have shown that text mining of job offers can, to some extent, help determine the responsibilities of a business analyst.

Opis:
Purpose: To identify the duties and responsibilities of project managers by analysing the content of online job advertisements. Design/methodology/approach: Job advertisements were automatically downloaded for 63 countries/areas available on Indeed. A text mining analysis of fragments of the advertisements describing the scope of duties was carried out. The text mining analysis included initial text processing, creating corpora of the documents, creating a document-term matrix, and using classic methods derived from data mining. Findings: The research established the most frequently used words and n-grams in job advertisements. They have been presented in the form of figures. The 2-grams are also presented in the form of a net, a directed graph. The LDA algorithm identified abstract topics describing the duties and responsibilities of project managers. The most frequent words, n-grams, and topics identified by the LDA algorithm were used to identify the duties and responsibilities of project managers. Research limitations/implications: Only job advertisements written in English were analysed. The postings were downloaded only for six days. An attempt to automatically identify the responsibilities section did not yield the expected results. Therefore, it was carried out manually for random advertisements, which reduced the number of analysed documents. The content of the job advertisements was not analysed by country/area. Practical implications: The method applied can be used by organisations training future project managers, to modify and better adapt curricula to the needs of the labour market. Originality/value: Studies have shown that text mining of job advertisements can help determine the duties and responsibilities of project managers.

Purpose: The paper presents an analysis of a scientific publication with regard to the frequency of words and n-grams. The research problem addressed was the question to what extent the text mining analysis of a scientific publication will allow to infer its content. Design/methodology/approach: The main research method is the analysis of tokenized text using word count functions, bigrams, and trigrams in selected sections of a scientific publication. The results of text mining analysis were compared with the classic, non-automated text analysis of the publication. The presented study is a pilot project in the form of a case study. Findings: The proposed method of analyzing a scientific text using an analysis of the frequency of words and n-grams enables inference of the content of the paper with regard to the names of variables involved in the study, the statistical apparatus used and the key literature cited. It should be observed, however, that the discussed method does not make it possible to establish which variables are moderators and which are mediators. Originality/value: In this paper, the text mining technique was used differently in the discussed study than in previous works. The publication was not examined in its entirety, as previous researchers did, but text mining analysis was applied to individual parts of the paper, i.e. the part discussing theoretical foundations of the research and the part presenting the research method, research results, and their discussion. This allowed for obtaining more precise results regarding the content of the publication.

Purpose: An attempt to identify the duties and responsibilities of the project manager by analysing job offers from a job website. An attempt to determine whether there were any changes between 2018 and 2019. Design/methodology/approach: Text mining was performed for fragments of job offers, describing the duties and responsibilities. The text mining analysis consisted of initial processing of the text, creation of a corpus of analysed documents, construction of a word frequency matrix and use of classical methods from the data mining are. Findings: The most common words in job offers are presented, as well as their correlation with other words. With the use of the Topic modeling algorithm, hidden topics describing the analysed job offers have been generated. These topics can also be used to identify the duties and responsibilities of a project manager. Research limitations/implications: Only the job offers meeting the following conditions were analysed: (1) they concerned the job of „project manager”; (2) the content was in Polish; (3) they were provided by www.pracuj.pl website; (4) they were collected from 09 to 11 April in 2018 and 2019. Practical implications: This method can be used by organizations training project managers, in order to modify and better adjust the curriculum to the needs of the labour market. Originality/value: Research has shown that text mining can be used to determine the responsibilities of a project manager by analysing job offers.

Opis:
Purpose: The objective of the paper is to use text mining to identify leading research domains concerning the smart city following an analysis of research articles with a high citation index according to the Web of Science. Design/methodology/approach: An original method is proposed for analysing academic texts using the R language, tokenisation, lemmatisation, n-grams and correspondence analysis. The author analysed fifty of the most cited articles indexed in the Web of Science from 2014 to 2019. Findings: The paper presents the advantages and drawbacks of the proposed method of analysing research publications. The assets include automation and repeatability of the analysis of a large number of documents and improved knowledge about links among the articles in terms of research domains. The disadvantage is the loss of information from diagrams and figures. The method identified two leading research domains related to the notion of the smart city, technologies and systems. The analysed publications were categorised by selected keywords. Research limitations/implications: Future work should include further refinement of the assumptions for the method, analyses of a more significant number of research texts and a narrowing down of the domain of the smart city. It is desirable to consider other functional domains of the city, such as energy, public health, environmental protection or transport. Practical implications: The proposed method can complement a standard literature analysis regarding the smart city. The leading research domains related to the smart city in the analysed articles were systems and technologies employed to improve how the city operates. Social implications: Text mining can be employed by various experts focusing on the smart city and constitutes a refreshing complement for other research methods, such as questionnaire surveys, interviews or observations. Originality/value The publication can be useful for researchers from various fields and managers seeking to create and use simple, useful methods and tools for analysing unstructured text documents for decision-making. The paper proposes a separate text mining analysis of abstracts and whole documents using n-grams. This yielded a more precise list of areas relevant to the smart city. The grouping was done using correspondence analysis of the fifty most cited articles indexed in the Web of Science from 2014 to 2019.
