Ok, now imagine you could extract any data from the web or any (un-)structured datasets… you got it ? okay now you certainly imagine it’s just a dream, or a very expensive technology.
I thought just like you, until i came across this API : http://www.alchemyapi.com/api/ with features like these :
- Entity Extraction
- Text Categorization
- Language Detection
- Concept Tagging
- Keyword Extraction
- Text Extraction
- Content Scraping and Structured Data Extraction
- Microformats Parsing/Extraction
- RSS / ATOM detection
And the basic API is for FREE, and available with a SDK in many languages. I already tried the API in Python and it will clearly be useful to me, now or in the future. Check it out, and tell me what you think.
