Ask HN: What open source license is appropriate for my project?

Hi guys, I'm thinking of open sourcing my project TextTeaser (http://www.textteaser.com/). What open source license is appropriate for it?

TextTeaser is an automatic summarization application and API. The algorithm used to summarize articles was formulated by me for my MS degree. It actually performs good enough. With open sourcing TextTeaser, I'll also release the research paper containing the algorithms implemented in it.
