Big Data Analytics department presents on GitHub the avtMonExp project on Python 3 for searching experts of a given domain in Twitter.
avtMonExp project on Python 3
1. Introduction The
avtMonExp project on Python 3 for searching experts of a given domain in Twitter. Work on the avtMonExp project was started in August 2016. This project implements some ideas from the E-Government Monitor project. The avtMonExp project includes the following main stages:
1. Search and retrieve data based on pre-defined criteria from Twitter.
2. Data analysis.
3. Evaluation of relevance and ranking of data by a unique algorithm developed by our company’s specialists.
4. Save data that corresponds to the specified criteria in the relational database.
5. Visualization of results in the browser on Google Maps. The
avtMonexp project was published on GitHub under the MIT license.
2. Requirements
2.1 The avtMonExp project requires the following main components:
- Python 3.6.3 – Python is a programming language that lets you work quickly
- TwitterSearch 1.0.2 by Christian Koepp – A Python library to easily iterate tweets found by the Twitter Search API
- python-gmaps 0.3.1 by Michał Jaworski – A Google Maps API client
- gmplot 1.2.0 by Michael Woods – Plotting data on Google Maps, the easy (stupid) way
- MySQL Community Server 5.7 – MySQL Community Edition is a freely downloadable version of the world’s most popular open source database that is supported by an active community of open source developers and enthusiasts
- MySQL Connector/Python – MySQL Connector/Python is a standardized database driver for Python platforms and development.
3. How to prepare and start using this project step by step

monexp_db_config = {
'user': '<your-user>',
'password': '<your-password>',
'host': '127.0.0.1',
'charset': 'utf8mb4'
}
3.4.3 To interact with your Twitter account with TwitterSearch Library need create Twitter App, and getting your application tokens
# avtMonExp/avtMonExp/tw_search_experts.py
def init_tw_search_lib(self, domain_keyword):
#...
# it's about time to create a TwitterSearch object with our secret tokens
ts = TwitterSearch(
consumer_key='<your-CONSUMER_KEY>',
consumer_secret='<your-CONSUMER_SECRET>',
access_token='<your-ACCESS_TOKEN>',
access_token_secret='<your-ACCESS_TOKEN_SECRET>'
)
# ...
3.4.4 To use python-gmaps Package for getting the latitude and longitude of the expert’s location from the field in database
# avtMonExp/avtMonExp/tw_search_experts.py
def tw_expert_location_geocoding(self, tw_user_location):
# ...
gmaps_request = Geocoding(api_key='<your-api_key>')
# ...
3.5 Run the avtMonExp application Run the main application module (
avtmonexp.py) from the avtMonExp package with the following console command: $ python avtmonexp.py

3.6.2 Displaying experts for each domain on Google Maps in default browser Results of data processing for each domain are saved in the
experts_data_viz_html project folder. The file name corresponds to the following pattern: domain_experts.html. The avtMonExp app automatically opens this file in the default browser.
For example, for the Wireless_Communications domain, the result is as follows: avtMonExp/avtMonExp/experts_data_viz_html/Wireless_Communications_experts.html
NOTE: If the same file already exists in the experts_data_viz_html folder when creating a new *.html file, it is copied to a file with the *.bak extension, and the existing *.html file is overwritten with a new *.html file with the same name. Example of plotting expert data from the specified domain on Google Maps as heatmap in the default browser
