Purpose For the purpose of informing tobacco intervention programs, this dataset was created and used to explore how online social networks of smokers differed from those of nonsmokers. The study was a secondary analysis of data collected as part of a randomized control trial conducted within Facebook. (See "Other References" in "Metadata" for parent study information.) Basic description of 4 anonymized data files of study participants. fbr_friends: Anonymized Facebook friends networks, basic ego demographics, basic ego social media activity fbr_family: Anonymized Facebook family networks, basic ego demographics, basic ego social media activity fbr_photos: Anonymized Facebook photo networks, basic ego demographics, basic ego social media activity fbr_groups: Anonymized Facebook group networks, basic ego demographics, basic ego social media activity Each network comprises the ego, the ego's first degree connections, and the (second degree) connections between the ego's friends. Missing data and users who did not have friend, family, photo, or group networks were cleaned from the data beforehand. Each data file contains the following columns of data, taken with participant knowledge and consent participant_id: Nonidentifying ids assigned to different study participants. is_smoker: Binary value (0,1) that takes on the value 1 if participant was a smoker and 0 otherwise. gender: One of three categories: male, female, or blank, which signified Other (different from missing data). country: One of four categories: Canada (ca), US (us), Mexico (mx), or Other (xx). likes_count: Numeric data indicating number of Facebook likes the participant had made up to the date the data was collected. wall_count: Numeric data indicating number of Facebook wall posts the participant had made up to the date the data was collected. t_count_page_views: Numeric data indicating number of pages participant had visited in the UbiQUITous app up to the date the data was collected. yearsOld: Numeric data indicating age in years of the participant; right censored at 90 years for data anonymity. vertices: Number of people in the participant's network. edges: Number of connections between people in the network. density: The portion of potential connections in a network that are actual connections; a network-level metric; calculated after removing ego and isolates. mean_betweenness_centrality: An average of the relative importance of all individuals within their own network; a network-level metric; calculated after removing ego and isolates. transitivity: The extent to which the relationship between two nodes in a network that are connected by an edge is transitive (calculated as the number of triads divided by all possible connections); a network-level metric; calculated after removing ego and isolates. mean_closeness: Average of how closely associated members are to one another; a network-level metric; calculated after removing ego and isolates. isolates2: Number of individuals with no connections other than to the ego; a network-level metric. diameter3: Maximum degree of separation between any two individuals in the network; a network-level metric; calculated after removing ego and isolates. clusters3: Number of subnetworks; a network-level metric; calculated after removing ego and isolates. communities3: Number of groups, sorted to increase dense connections within the group and decrease sparse connections outside it (i.e., to maximize modularity); a network-level metric; calculated after removing ego and isolates. modularity3: The strength of division of a network into communities (calculated as the fraction of ties between community members in excess of the expected number of ties within communities if ties were random); a network-level metric.

Abstract

This data set contains the underlying data of the paper “’ENGAGING THE PEOPLE’: IS SOCIAL MEDIA COVERAGE OF EU POLICY ASSOCIATED WITH PUBLIC SUPPORT FOR EUROPEAN INTEGRATION?”.

Data openly available within this dataset are a subset of the two following data sets, which contains all the relevant data of Work Package 3 and Work Package 5 of PERCEIVE project:

Data set: “PERCEIVE: WP3: Effectiveness of communication strategies of EU projects” https://doi.org/10.5281/zenodo.3371133

Data set: “PERCEIVE: WP5: The multiplicity of shared meanings of EU and Cohesion Regional and Urban Policy at different discursive levels” https://doi.org/10.5281/zenodo.3371174

For the paper we collected Facebook posts referred to EU CP policies. We don’t have the permission to share these data (as they are protected by copyright), but all the sources are described in Deliverable 5.2, which is public (see http://doi.org/10.6092/unibo/amsacta/5726 or http://doi.org/10.5281/zenodo.1318184). We analyzed the textual content of data to construct a database of discursive topics in Task5.4. Data set includes the results of topic modeling and of a sentiment analysis performed on the Facebook homepages of Local Management Authorities (LMA) of PERCEIVE case study regions.

Content of the files:

1 sub-folder, named “A_Stopword”, which contains all the stopword lists used for performing Topic Modeling. These are 6 .txt files, one for each language: Austrian, Italian, Polish, Romanian, Spanish, Swedish (“stoplist_file_[nation].txt”).

1 sub-folder which contain the Topic Modeling results for Facebook profiles of the Local Managing Authorities for Austria, Italy, Poland, Romania, Spain, and Sweden (sub-folder “B_Facebook”, 12 .txt files). For each case, a file “[source]-keys.txt” lists the 100 most important words for each topic, while a file “[source]-composition.txt” details the topic composition of each textual source. These files were obtained through Mallet software[1].

File “SentimentFB.xlsx” contains data regarding the sentiment analysis for contents on Facebook homepages of Local Managing Authorities. The first column indicates the country, as well as row labels (see below). Columns 2-21 indicate the number id of the topics for each topic model (national level). The three rightmost columns of the file represent respectively a) the name of the lexicon used to detect sentiment orientation (i.e. “VADER”); c) the average sentiment score for positive, neutral and average words for each lexicon and each country; and c) the sentiment score across all topics in a country.

File “topics_prevalence_and_clustering.xlsx” contains data regarding the three clusters of topics analyzed in the paper. The first column represents the ID of each topic; the second column reports the cluster of each topic; the third and the fourth columns report the average prevalence of each topic (rows) in posts and comments, respectively. As these data refer to a regional case study, these columns refer the first region for each country; the sixth and the seventh columns report the average prevalence of each topic (rows) in posts and comments for the second region analyzed (only for those countries where we analyzed two regions); the eighth and ninth columns reports the average prevalence of topics and comments, respectively, for each country; and finally the tenth column reports the country to which data in the previous two columns are referred.

The report provides a snapshot of the social media usage trends amongst online Canadian adults based on an online survey of 1500 participants. Canada continues to be one of the most connected countries in the world. An overwhelming majority of online Canadian adults (94%) have an account on at least one social media platform. However, the 2022 survey results show that the COVID-19 pandemic has ushered in some changes in how and where Canadians are spending their time on social media. Dominant platforms such as Facebook, messaging apps and YouTube are still on top but are losing ground to newer platforms such as TikTok and more niche platforms such as Reddit and Twitch.

The peer-reviewed publication for this dataset has been presented in the 2022 Annual Conference of the North American Chapter of the Association for Computational Linguistics (NAACL), and can be accessed here: https://arxiv.org/abs/2205.02596. Please cite this when using the dataset.

This dataset contains a heterogeneous set of True and False COVID claims and online sources of information for each claim.

The claims have been obtained from online fact-checking sources, existing datasets and research challenges. It combines different data sources with different foci, thus enabling a comprehensive approach that combines different media (Twitter, Facebook, general websites, academia), information domains (health, scholar, media), information types (news, claims) and applications (information retrieval, veracity evaluation).

The processing of the claims included an extensive de-duplication process eliminating repeated or very similar claims. The dataset is presented in a LARGE and a SMALL version, accounting for different degrees of similarity between the remaining claims (excluding respectively claims with a 90% and 99% probability of being similar, as obtained through the MonoT5 model). The similarity of claims was analysed using BM25 (Robertson et al., 1995; Crestani et al., 1998; Robertson and Zaragoza, 2009) with MonoT5 re-ranking (Nogueira et al., 2020), and BERTScore (Zhang et al., 2019).

The processing of the content also involved removing claims making only a direct reference to existing content in other media (audio, video, photos); automatically obtained content not representing claims; and entries with claims or fact-checking sources in languages other than English.

The claims were analysed to identify types of claims that may be of particular interest, either for inclusion or exclusion depending on the type of analysis. The following types were identified: (1) Multimodal; (2) Social media references; (3) Claims including questions; (4) Claims including numerical content; (5) Named entities, including: PERSON − People, including fictional; ORGANIZATION − Companies, agencies, institutions, etc.; GPE − Countries, cities, states; FACILITY − Buildings, highways, etc. These entities have been detected using a RoBERTa base English model (Liu et al., 2019) trained on the OntoNotes Release 5.0 dataset (Weischedel et al., 2013) using Spacy.

The original labels for the claims have been reviewed and homogenised from the different criteria used by each original fact-checker into the final True and False labels.

The data sources used are:

- The CoronaVirusFacts/DatosCoronaVirus Alliance Database. https://www.poynter.org/ifcn-covid-19-misinformation/

- CoAID dataset (Cui and Lee, 2020) https://github.com/cuilimeng/CoAID

- TREC COVID challenge (Voorhees et al., 2021; Roberts et al., 2020) https://ir.nist.gov/covidSubmit/data.html

The LARGE dataset contains 5,143 claims (1,810 False and 3,333 True), and the SMALL version 1,709 claims (477 False and 1,232 True).

The entries in the dataset contain the following information:

- Claim. Text of the claim.

- Claim label. The labels are: False, and True.

- Claim source. The sources include mostly fact-checking websites, health information websites, health clinics, public institutions sites, and peer-reviewed scientific journals.

- Original information source. Information about which general information source was used to obtain the claim.

- Claim type. The different types, previously explained, are: Multimodal, Social Media, Questions, Numerical, and Named Entities.

This feature layer is part of SDGs Today. Please see sdgstoday.orgTo ensure that all women and girls can benefit from the digital revolution, tracking progress on gender inequalities in relation to internet and mobile access and use is more important than ever. Unfortunately, the data are significantly lacking in geographic coverage, comparability, and timeliness. The University of Oxford and Qatar Computing Research Institute (QCRI), with support from Data2X, are collaborating to measure digital gender gaps in real time. The Digital Gender Gaps project uses Facebook marketing data to generate a country-level dataset combining ‘online’ indicators of Facebook users by gender, age, and device type. These online indicators are used to predict internet and mobile use gender gaps by validating them against data on gender gaps in internet and mobile access from nationally-representative surveys where available. The data shows the internet gender gap (ratio of female-to-male internet use) and mobile gender gap (female-to-male mobile use) estimated using the Facebook Gender Gap Index (female-to-male ratio of Facebook users).Read more about the methodology here.

More than 200 million businesses use Facebook globally. The goal of Meta’s quarterly Small Business Surveys is to learn about the unique perspectives, challenges and opportunities of small and medium-sized businesses (SMBs).

The Future of Business (FoB) Survey is conducted biannually in partnership with the World Bank and the Organisation for Economic Cooperation and Development (OECD) across nearly 100 countries. The target population consists of SMEs that have an active Facebook Business Page and include both newer and longer-standing businesses, spanning across a variety of sectors. Meta also conducts the Global State of Small Business (GSoSB) Survey bi-annually in partnership with various academic partners across approximately 30 countries. Similarly to the FoB Survey, the target population is active Facebook Page Administrators, but also includes the general population of Facebook users.

Survey questions for all surveys cover a range of topics depending on the survey wave such as business characteristics, challenges, financials and strategy in addition to custom modules related to regulation, gender inequity, access to finance, digital technologies, reduction in revenues, business closures, international trade, inflation, reduction of employees and challenges/needs of the business.

Aggregated country level data for each survey wave is available to the public on HDX and controlled access microdata is available to Data for Good at Meta partners.

Analysis of ‘COVID-19: Holidays of countries’ provided by Analyst-2 (analyst-2.ai), based on source dataset retrieved from https://www.kaggle.com/vbmokin/covid19-holidays-of-countries on 28 January 2022.

--- Dataset description provided by original source is as follows ---

Context

This research is devoted to the analysis of the impact of holidays on the statistics of confirmed coronavirus diseases. The Prophet using the holidays library with holidays of countries and their regions. As of 30 June 2020, only 62 countries (some with regions) are available in the holidays library:

['AR', 'AT', 'AU', 'BD', 'BE', 'BG', 'BR', 'BY', 'CA', 'CH', 'CL', 'CN', 'CO', 'CZ', 'DE', 'DK', 'DO', 'EE', 'EG', 'ES', 'FI', 'FR', 'GB', 'GR', 'HN', 'HR', 'HU', 'ID', 'IE', 'IL', 'IN', 'IS', 'IT', 'JP', 'KE', 'KR', 'LT', 'LU', 'MX', 'MY', 'NG', 'NI', 'NL', 'NO', 'NZ', 'PE', 'PH', 'PK', 'PL', 'PT', 'PY', 'RS', 'RU', 'SE', 'SG', 'SI', 'SK', 'TH', 'TR', 'UA', 'US', 'ZA'] or ['Argentina', 'Australia', 'Austria', 'Bangladesh', 'Belarus', 'Belgium', 'Brazil', 'Bulgaria', 'Canada', 'Chile', 'China', 'Colombia', 'Croatia', 'Czechia', 'Denmark', 'Dominican Republic', 'Egypt', 'Estonia', 'Finland', 'France', 'Germany', 'Greece', 'Honduras', 'Hungary', 'Iceland', 'India', 'Indonesia', 'Ireland', 'Israel', 'Italy', 'Japan', 'Kenya', 'Korea, Republic of', 'Lithuania', 'Luxembourg', 'Malaysia', 'Mexico', 'Netherlands', 'New Zealand', 'Nicaragua', 'Nigeria', 'Norway', 'Pakistan', 'Paraguay', 'Peru', 'Philippines', 'Poland', 'Portugal', 'Russian Federation', 'Serbia', 'Singapore', 'Slovakia', 'Slovenia', 'South Africa', 'Spain', 'Sweden', 'Switzerland', 'Thailand', 'Turkey', 'Ukraine', 'United Kingdom', 'United States']

I will note at once that the list of available countries in the description of the holidays library contains a lot of mistakes, which I wrote to the authors.

When I asked if this list would expand, the Prophet team made it clear that they were waiting for help from the community with holidays library expand.

As of Jan 2021 (version 8.4.1), 67 countries (some with regions) are available in the holidays library: a number of data have been refined and countries ['BI', 'LV', 'MA', 'RO', 'VN' - two-letter country codes or alpha_2 of the country (ISO 3166)] added.

Unfortunately, the format of the holidays library is not very suitable for coronavirus problems, as it has a number of disadvantages. First, the names of the countries are given in one word, which makes it difficult for many of them to identify them according to their common names (ISO 3166). It is best that the dataset contains the common name and two-letter abbreviation in English according to ISO 3166 (see pycountry). Second, the dates are not adapted to the potential impact of the holidays on coronavirus statistics. It is known that after the moment of infection, the active manifestation of symptoms occurs with a delay of 4-10 days, that is a person is likely to get into the statistics on the number of diseases only after 4-7 days. Therefore, it is advisable to use the dates window of impacts: ``` Lower_window = [4, 7] Upper_window = [7, 10]

`Lower_window <= 0`
But my [request](https://github.com/facebook/prophet/issues/1588#issue-661098613) to allow positive numbers in this parameter [was refused](https://github.com/facebook/prophet/issues/1588#issuecomment-661984730) by the Prophet team and [advised](https://github.com/facebook/prophet/issues/1588#issuecomment-661984730) to simply move the dates themselves.
Therefore, it is advisable to shift the holiday dates by 7 days. If the researcher thinks that 7 is too much and enough is 4 days, then he simply indicates "Lower" of the window in -3. Actually, by default, it makes sense to specify parameters:

Lower_window = -3 Upper_window = 3

If necessary, these settings are easy to change

### Content

This dataset:
1. Contains ISO codes, ISO names (common and official) (ISO 3166) of **70** countries (3 European countries **['Albania' - 'AL', 'Georgia' - 'GE', 'Moldova' - 'MD']** have been added).
2. Contains imported dates from the holidays library for 2020-01-20-2021-12-31 (all countries from holidays library as of Jan 2021), and the same dates, but moved 7 days forward.
3. Holidays of countries that are not in the list of holidays of the library, but which are in the data of the World Health Organization and on which considerable statistics of diseases on coronavirus are already collected.
4. Parameters for Prophet model:
`lower_window, upper_window, prior_scale`
If you find errors, please write to the [Discussion](https://www.kaggle.com/vbmokin/covid19-holidays-of-countries/discussion).

It is planned to periodically update (and, if necessary, correct) this dataset.

### Inspiration

The main task for which this dataset was created is to study the impact of holidays on the accuracy of predicting coronavirus diseases, identifying new patterns, and forming optimal solutions to counteract or minimize its spread.

Tasks that need to be solved to improve this dataset in order to increase the accuracy of modeling the impact of holidays on the number of coronavirus patients:
1) Expanding the list of countries
2) Clarification of holiday dates
3) Clarification of parameters 
`lower_window, upper_window, prior_scale`
they must be unique for each country and each holiday.

Also, it is advisable to carry out similar work for each region of countries, but this will not be done in this dataset.

The global number of Facebook users was forecast to continuously increase between 2023 and 2027 by in total 391 million users (+14.36 percent). After the fourth consecutive increasing year, the Facebook user base is estimated to reach 3.1 billion users and therefore a new peak in 2027. Notably, the number of Facebook users was continuously increasing over the past years.User figures, shown here regarding the platform Facebook, have been estimated by taking into account company filings or press material, secondary research, app downloads and traffic data. They refer to the average monthly active users over the period and count multiple accounts by persons only once.The shown data are an excerpt of Statista's Key Market Indicators (KMI). The KMI are a collection of primary and secondary indicators on the macro-economic, demographic and technological environment in up to 150 countries and regions worldwide. All indicators are sourced from international and national statistical offices, trade associations and the trade press and they are processed to generate comparable data sets (see supplementary notes under details for more information).
