------------------
ONE-TIME SETUP
------------------
Run the setup script to fetch the following tools, libraries, and prepare all javascript
files needed by Termite. This script only needs to be run once when Termite is first
downloaded onto a new machine.
>> ./setup.sh
Libraries fetched include:
* mallet
* stmt
* closure-compiler.js
* d3.v3.js
* jquery.js
* underscore.js
* backbone.js
* html5slider.js
The script creates a minified version of all javascript files.
-----------------------
BUILD A TOPIC MODEL
-----------------------
Building a topic model in Termite requires running a single python script. The script reads
in an input text corpus, and produces an output folder whose content can be inspected
using a web browser, described in the next section.
Customize configuration file with the following information. A sample configuration
file can be found in 'example.cfg'
[Corpus] path to text corpus
[TopicModel] directory for holding topic model outputs
[TopicModel] number of topics to train
[TopicModel] topic model (either mallet or stmt)
[Termite] number of terms to seriate
[Termite] path to save Termite-internal working files
Process the text corpus, and build a topic model by running the execution script.
Execution time will vary depending on the size of the corpus.
>> ./execute.py <your_config_file.cfg>
The execution script calls in order:
1. pipeline/tokenize.py Tokenize the text corpus
2. pipeline/train_mallet.py Train a topic model using MALLET
pipeline/train_stmt.py or STMT.
3. pipeline/compute_saliency.py Compute term saliency
4. pipeline/compute_similarity.py Compute term similarity
5. pipeline/compute_seriation.py: Seriates terms
6. pipeline/prepare_data_for_client.py: Generates datafiles for client
7. pipeline/prepare_vis_for_client.py: Copies necessary scripts for client
----------------------------
VIEW TOPIC MODEL OUTPUTS
----------------------------
You are now ready to visualize the topic model outputs! Termite's output can be viewed in
a web browser. To view the files locally (on your own computer), you need to set up a local
web server. Alternatively, you may copy the output folder to a web server to publish the results.
Termite outputs are stored in the 'public_html' subfolder within the output directory.
To set up a local webserver:
1. Change into output directory (specified in the configuration file)
>> cd <output_folder>/public_html
2. Start a local server using python
>> ./web.sh
3. Open http://localhost:8888 in a modern web browser (Chrome, Safari, Firefox, or Opera)
to view a visualization of the model outputs.
To publish the results on a webserver:
1. Copy public_html directory to your remote server.
-----------------------------
TOPIC MODEL VISUALIZATION
-----------------------------
The visualization should consist of a matrix view with a frequency bar view to the right.
The top right contains user controls, two slider bars and one input text box. User
controls are explained in more detail in the 'VISUALIZATION USE CASES' section.
When the mouse is placed over terms, topics, circles, or bars in the matrix or frequency
bar view, the associated term, topic, bar, and circles will be highlighted in both views.
---------------------------
VISUALIZATION USE CASES
---------------------------
The Termite visualization tool has a set of user controls in the top right section of the
webpage. The user may specify
* the number of terms with highest affinity to show
* the number of terms with highest saliency to show
* always display specific terms
* always display 20 most frequent terms belonging to selected topics
* click on a topic to select/color the topic
* mouse over a topic/term to highlight the topic/term
(Note: the highest affinity term set and highest saliency term set may contain overlapping words)
