Text Density Crawler

This project is a simple web crawler that searches for a keyword from a starting URL and crawls through connected web pages.

It extracts text from web pages using the techniques from the "DOM Based Content Extraction via Text Density" research paper and prints the text containing the specified keyword along with the URL where it was found.

Benchmark Performance

The following benchmark performance was observed on a MacBook Pro with the following specifications:

OS version: 13.2.1(22D68)
Processor: 2.3 GHz Quad-Core Intel Core i5
Memory: 16GB 2133 MHz LPDDR3
Graphics: Intel Iris Plus Graphics 655 1536 MB

The performance was measured by running the crawler for 10 seconds:

[ 1 SECOND] REQUEST_COUNT :  276 PARSING_COUNT :  74
[ 2 SECOND] REQUEST_COUNT :  567 PARSING_COUNT :  361
[ 3 SECOND] REQUEST_COUNT :  937 PARSING_COUNT :  731
[ 4 SECOND] REQUEST_COUNT :  1192 PARSING_COUNT :  985
[ 5 SECOND] REQUEST_COUNT :  1525 PARSING_COUNT :  1317
[ 6 SECOND] REQUEST_COUNT :  1811 PARSING_COUNT :  1601
[ 7 SECOND] REQUEST_COUNT :  1993 PARSING_COUNT :  1785
[ 8 SECOND] REQUEST_COUNT :  2194 PARSING_COUNT :  1985
[ 9 SECOND] REQUEST_COUNT :  2373 PARSING_COUNT :  2163
[ 10 SECOND] REQUEST_COUNT :  2503 PARSING_COUNT :  2292
