### Amount and Relevance of the Collected Twitter Data  
During the nine months, 24,821 tweets were collected, which related to the research area of Oxford Street in London. After removing the retweets, the sample included 22,530 tweets collected using defined hashtags and keywords (_#oxford_, _#oxfordstreet_, _#oxford_, _oxford_ and _oxford street_), and 327 collected tweets contained geotag, while only 27 tweets were collected based on geotagging at Oxford Street. It was noticed that the intensity of certain tweets was higher at the time when an event such as the London protests or the anti-Semitic act on the bus took place. In addition to the above, there were a very small sample of tweets that have geotags. That share is 1.39%. It is assumed that the reason is that most of the social network users switch off geolocation, both on the application and on the phone.  
The amount and relevance of this sample can be compared with the data related to the conducted public consultations related to the future appearance and use of Oxford Street and its contact zone (Oxford Street District--OSD). The first consultations were held in

the period from 6 November 2017 until 3 January 2018, shortly after the announcement of the Mayor of London that \"about half a mile of the street from Oxford Circus to Orchard Street could become a \"traffic-free pedestrian boulevard\" [26]. In the specified period, around a million people were directly contacted for the public consultation [18]. During the consultation, 14,377 responses were collected, \"with just over 9000--about 64%--either supporting the project outright or backing the plans with some concerns about certain elements\" [27].  
Public consultations on the draft Oxford Street District Place Strategy were held from 6 November to 16 December 2018, which was preceded by the presentation of the Strategy to the residents, employers and those visiting or working in the area. Consultations were conducted through online questionnaires (on the website and by email) and direct surveys. During the 6 weeks of consultation, 1800 online questionnaires were completed, while 354 were directly surveyed [28]. Considering the respondent type, the largest group were regular visitors to the OSD (61%), followed by residents of Westminster (34%) and District workers (20%).  
Considering the results of the official public consultation reports, it can be interpreted that the data collected from Twitter can be characterized as relevant, having in mind both the amount (2757 tweets per month) and the thematic framework of interest, determined by the choice of content that contains specific terms and hashtags. An increase in the sample and more concrete answers and discussions could be expected after the implementation of a social network campaign that would be focused on a specific topic.
