==Project Introduction==
This project that utilizes Selenium and Machine Learning to get good candidate web pages and classify web pages as a demo day page containing a list of cohort companies, ultimately to gather good candidates to push to Mechanical Turk. The code is written using Python 3 using Selenium and Tensorflow (Keras). This article will also preliminaries of the Mechanical Turk tool and how it can be used to collect data.
==Project Goal==
The RNN is still under much development. Modifying anything in this folder is not recommended
All the other folders are used for experimenting purposes, please don't touch them. If you want to understand more about the files as a general user, go to the section A Quick Glance through the File in The Directory below. If you are a developer, go to the Advance User Guide section.
==General User Guide: How to Use this Project (Random Forest model)==
NEVER touch the TrainingHTML folder, datareader.py or the classifier.txt. These are used internally to train data.
==A Quick Glance through the File in The Directory==
All working file is stored in this folder:
E:\McNair\Projects\Accelerator Demo Day\Test Run
The file
==Amazon Mechanical Turk==
Please refer to: [[Amazon Mechanical Turk for Analyzing Demo Day Classifier's Results]]
==Hand Collecting Data==
To crawl, we only looked for data on accelerators which did not receive venture capital data (which Ed found via VentureXpert) and lacked timing info. The purpose of this crawl is to find timing info where we cannot find it otherwise, and if a company received VC we can find timing info via that investment. The file we used to find instances in which we lack timing info and lacked VC is:
/bulk/McNair/Projects/Accelerators/Summer 2018/Merged W Crunchbase Data as of July 17.xlsx
We filtered this sheet in Excel (and checked our work by filtering in SQL) and found 809 companies that lacked timing info and didn't receive VC. From this, we found 74 accelerators which we needed to crawl for.
We used the crawler to search for cohort companies listed for these accelerators.
During the initial test run, the number of good pages was 359. The data is then handled by hand by fellow interns.
The file for hand-coding is in:
/bulk/McNair/Projects/Accelerator Demo Day/Test Run/CrawledDemoDayHTMLFull/'''FinalResultWithURL'''
For the sake of collaboration, the team copied this information to a Google Sheet, accessible here:
https://docs.google.com/spreadsheets/d/16Suyp364lMkmUuUmK2dy_9MeSoS1X4DfFl3dYYDGPT4/edit?usp=sharing
We split the process into four parts. Each interns will do the following:
1. Go to the given URL.
2. Record whether the page is good data (column F); this can later be used by [[Minh Le]] to refine/fine-tune training data.
3. Record whether the page is announcing a cohort or recapping/explaining a demo day (column G). This variable will be used to decide if we should subtract weeks from the given date (e.g. if it is recapping a demo day, the cohort went through the accelerator for the past ~12 weeks, and we should subtract weeks as such).
4. Record date, month, year, and the companies listed for that given accelerator.
5. Note any any information, such as a cohort's special name.
Once this process is finished, we will filter only the 1s in Column F, and [[Connor Rothschild]] and [[Maxine Tao]] will work to populate empty cells in The File to Rule Them All with that data.
==Advance User Guide: An in-depth look into the project and the various settings==
===Accelerators needed to Crawl===The name lists of Accelerators to crawl is stored in the file: E:\McNair\Projects\Accelerator Demo Day\Test Run\ListOfAccsToCrawl.txt ===Training Data===Training data is stored in the folder: E:\McNair\Projects\Accelerator Demo Day\Test Run\TrainingHTML ===The Crawler Functionality===
The crawler functionality is stored in the file:
STEP1_crawl.py
Because apparently for some reason it stopped grabbing the first web page (I think because google may have modified how their website looks.
===The Classifier===
===Input (Features)===
The RNN currently has a ~50% accuracy on both train and est data, which is rather concerning.
Test : train ration ratio is 1:3 (25/75)
Both model is currently using the Bag-of-word approach to preprocess data, but I will try to use Yang's code in the industry classifier to preprocess using word2vec. I'm not familiar with this approach, but I will try to learn this.
