Dr. Rada MihalceaThe NewScientist article Sharing a joke could help man and robot interact said
A MAN walks into a bar: “Ouch!” You might not find it funny, but at least you got the joke. That’s more than can be said for computers, which, despite radical advances in artificial intelligence, remain notably devoid of a funny bone.
Previously AI researchers have tended not to try mimicking humor, largely because the human sense of humor is so subjective and complex, making it difficult to program.
Meanwhile Rada Mihalcea and colleagues at the University of North Texas in Denton have built a different kind of humor-spotting bot. Instead of working out why a sentence might be funny, it learns the frequencies of words that are found in jokes, and uses that to identify humor. “We got a lot of ‘can’t’, ‘don’t’, ‘drunk’ and ‘poor’,” Mihalcea says. “People like laughing about bad things.”

- Lexical Semantics (including: semantic similarity, word sense disambiguation, semantic parsing)
- Graph-based Algorithms for Natural Language Processing (with applications including: text summarization, word sense disambiguation, keyphrase extraction)
- Building and Exploiting Parallel Texts, Multilingual NLP
- Computational Humor
- Building Annotated Corpora with Volunteer Contributions over the Web
- Sentiment and Subjectivity Analysis
- SenseLearner: tools for finding the meaning of all words in unrestricted text
- Teach-Computers: data collection with volunteer contributions over the Web
- TextRank: graph-based ranking algorithms for text processing
- Babylon: methods for building and exploiting parallel texts. Related resources for word/sentence alignment.
- Computational Humor: computational approaches for humor recognition and generation
