C# Computer Skills
The Courses "Programming and Algorithms" and "Programming Languages" (recommended).

Students should be able to design the data structure of a search engine, explore crawling tools, understand the different stages of natural language processing, implement an inverted index as well as data search models and Cranfield assessment.
