Zemanta

Zemanta is a platform that aims to help online content producers find related content from across the web to enhance their publication(s). A blog, an article or a web page can be fed into its system, which then recognises it and returns suggested images, smart links, keywords and relevant related stories from the web.

Based on the input, the engine recommends links to content from: Amazon, Crunchbase, Wikipedia, Freebase, MusicBrainz, Flickr, Daylife and social networks.

Zemanta analyses copy through its proprietary natural language processing and semantic algorithms, and statistically compares its contextual framework to a pre-indexed database of content. The system uses a combination of machine learning techniques and end-user input that enables the engine to be trained and to constantly improve the recommendations.

With the launch of the public API, Zemanta is opening up its technology for blogging platforms, media companies and other content database owners to enable them to leverage their unstructured content and enhance it with relevant related content.

Byteplay

Byteplay's flagship product, DotHomes is a Real Estate search engine.
DotHomes allows home seekers across the US, UK and South Africa to search over thousands of real estate Websites from one place. Underlying DotHomes' search mechanism is a Machine learning data-mining technology, which automatically finds property listings on listing broker / agent Websites, and extracts relevant information. This allows for extremely rapid scaling up of coverage, whilst still getting data directly from source Websites (as opposed to getting data from smaller aggregators).

DotHomes employs an advertising business model. It does not charge real estate listing brokers to have their property listings appear in the DotHomes search index. Instead it provides ancillary real estate services with an opportunity to advertise alongside the free "organic" search results.
