Project
This is a ML project that classifies webpages as a demo day page containing a list of cohort companies, currently using scikit learn's random forest model and a bag of words approach. The classifier itself takes:
Features: The frequencies of each word from words.txt in the webpage. This is calculated by web_demo_features.py in the same directory. It also takes the frequencies of years from 1900-2099, month words grouped in seasons, and phrases of the form "# startups". It also takes the number of simple links (links in the form www.abc.com or www.abc.org) and the number of those that are attached to images. It also takes the number of "strong" html tags in the body. These features can be extended by adding words to words.txt or regexes to PATTERNS in web_demo_features.py.
Training classifications: A set of webpages hand-classified as to whether they contain a list of cohort companies. This is stored in classification.txt, which is a tsv equivalent of Demo Day URLS.xlsx. Keep in mind that this txt file must be utf-8 encoded. In textpad, one can convert a file to utf-8 by pressing save-as, and changing the encoding at the bottom.
A demo day page is an advertisement page for a "demo day," which is a day that cohorts graduating from accelerators can pitch their ideas to investors. These demo days give us a good idea of when these cohorts graduated from their accelerator.
Project location:
E:\McNair\Projects\Accelerators\Spring 2018\demo_day_classifier\
Training data:
E:\McNair\Projects\Accelerators\Spring 2018\demo_day_classifier\DemoDayHTMLFull\Demo Day URLs.xlsx
Usage:
- Steps to train the model: Put all of the html files to be used in DemoDayHTMLFull. Then run web_demo_features.py to generate the features matrix, training_features.txt. Then, run demo_day_classifier_randforest.py to generate the model, classifier.pkl.
- Steps to run the model on google results: In the file crawl_and_classify.py, set the variables to whatever is wanted. Then, run this command:
python3 crawl_and_classify.py
It will download all of the html files into the directory CrawledHTMLPages, and then it will generate a matrix of features, CrawledHTMLPages\features.txt. It will then run the trained model saved in classifier.pkl to predict whether these pages are demo day pages, and then it will save the results to CrawledHTMLPages\predicted.txt. The HTML pages are then moved into CrawledHTMlPages/demoday/ or CrawledHtmlPages/non_demoday based on their prediction.
Possible further steps
Changed from Bag-Of-Words model to a more powerful neural network, perhaps an RNN.
