These platforms own tremendous amount of data about users\u2019 behaviors and sentiments since people create, share or exchange their information, ideas, pictures or video using them. One of these popular platforms is Twitter, which via its voluntary information sharing structure, provides researchers data potential of benefit for their studies. Based on Twitter data, in this study a multilingual sentiment detection framework is proposed to compute European Gross National Happiness (GNH). This framework consists of a novel data collection, filtering and sampling method, and a newly constructed multilingual sentiment detection algorithm for social media big data, and tested with nine European countries (United Kingdom, Germany, Sweden, Turkey, Portugal, The Netherlands, Italy, France and Spain) and their national languages over a six year period. The reliability of the data is checked with peak\/troughs comparison for special days from Wikipedia news lists. The validity is checked with a group of correlation analyses with OECD Life Satisfaction survey reports\u2019, Euro-Dollar and other currency exchanges, and national stock market time series data. After validity and reliability confirmations, the European GNH map is drawn for six years. The main problem addressed is to propose a novel multilingual social media sentiment analysis framework for calculating GNH for countries and change the way of OECD type organizations\u2019 survey and interview methodology. Also, it is believed that this framework can serve more detailed results (e.g., daily or hourly sentiments of society in different languages).<\/jats:p>","DOI":"10.3390\/info9050102","type":"journal-article","created":{"date-parts":[[2018,4,25]],"date-time":"2018-04-25T06:31:55Z","timestamp":1524637915000},"page":"102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["#europehappinessmap: A Framework for Multi-Lingual Sentiment Analysis via Social Media Big Data (A Twitter Case Study)"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6670-8886","authenticated-orcid":false,"given":"Mustafa","family":"Co\u015fkun","sequence":"first","affiliation":[{"name":"Department of Management Information Systems, Bogazici University, 34470 Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8991-4033","authenticated-orcid":false,"given":"Meltem","family":"Ozturan","sequence":"additional","affiliation":[{"name":"Department of Management Information Systems, Bogazici University, 34470 Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Hanna, B., Kee, K.F., and Robertson, B.W.
