natural language processing

hbrmdc, 2018-09-01 07:49:24

I am looking for libraries or services that can help with natural language processing for the Russian language. Here is what you are specifically interested in:
1. Translate words into the initial form: "They built" => "they", "build"
2. Recognize phrases: "They built the railway" => "they", "build", "railroad "
3. Associate the particle "not" with the verb to which it refers: "They did not build the railway" => "they" "do not build", "railway"
4. Interpret idioms and figures of speech: "well, the weather" => "bad weather"
Any advice? Libraries, services, sources of information on the topic - anything
