About
80legs was founded in 2009 with the simple idea of making web data more accessible. The company first focused on providing web crawling services to a wide variety of clients. As our customer base grew, we developed a more scalable, productized platform that would empower our users to setup, design, and run their own web crawls. This philosophy of accessible web data has driven us to strengthen and increase our product offerings. In 2012, the 80legs team re-established itself as Datafiniti, a new product that provides instant access to high-quality web data, without the need for users to run their own web crawls. While Datafiniti scales to include more and more data, we continue to innovate on 80legs as well, as we strive to fulfill our mission of making web data available to everyone. Run your own web crawls on our cloud-enabled platform. Pull custom data from our crawl of the entire web.

About
LexVec is a word embedding model that achieves state-of-the-art results in multiple natural language processing tasks by factorizing the Positive Pointwise Mutual Information (PPMI) matrix using stochastic gradient descent. This approach assigns heavier penalties for errors on frequent co-occurrences while accounting for negative co-occurrences. Pre-trained vectors are available, including a common crawl dataset with 58 billion tokens and 2 million words in 300 dimensions, and an English Wikipedia 2015 + NewsCrawl dataset with 7 billion tokens and 368,999 words in 300 dimensions. Evaluations demonstrate that LexVec matches or outperforms other models like word2vec in terms of word similarity and analogy tasks. The implementation is open source under the MIT License and is available on GitHub.
