Frontend
just link the php folder to some Apache / NGINX document root, it should work straight away. Just an extra note on authentication: the web interface requires users to login for profiling purposes, but presently I have not implemented any registration mechanism. just add some user to the database manually, the only fields required to authenticate are fom_user.user_login and fom_user.user_pass (password will be matched against an md5 hash, just use an online generator to create one)
from the interface, you will see a light-bulb icon, indicating a quick help available on-line for all the frontend functionalities, a quick resume is shown below.
this is a recent screenshot of how the search results should appear if everything is working correctly
- type in some text in the search box, a live search box will appear showing results (topic + number of appearances of that topic in the fom_cluster table)
- click on one of the topic, this will load a time-lapse visualization of all the clusters containing the selected topic.
- clusters are coloured with a gradient going from green (most recent) to purple (oldest). a concentration of clusters around a specific tonality of colour will indicate that the selected topic has been "hot" for the time-frame around the interval shown.
this is a recent screenshot of how the drag zoom stat results should appear if everything is working correctly
- select a geo-box by pressing shift and drag-zoom around a location of interest
- a side panel will show two search forms, allowing to specify a data range
- on the right panel, stats of the number of cluster and posts for the selected geo-location (clusters must be created with the commands specified above)
- on the left panel, stats of number of posts and languages emitted within the selected geo-location, downloadable in CSV format
- select a date (or range of dates) from the dropdown menu to see the clusters created for the selected item. this clusters must be created manually with the commands specified above
- display a TF-IDF graph of the date selecte clicking on the little table icon close to the dropdown
- click on a cluster (geo-marker) to see its content (topic and keywords) and display its size on the map
- after displaying the stats of a cluster, click on the list of posts in the side panel to display the content of a specific post
