The easiest way to use the pipeline is from its web interface with a plain text document. The pipeline uses in-house and external tools on the text to segment it into sentences and paragraphs, tokenise, tag parts-of-speech, look up in dictionaries and analyse compounds. The pipeline can also be run using a web API with XML results, and it is run locally at Språkbanken to prepare the documents in Korp, our corpus search tool. While the most sophisticated support is for modern Swedish, the pipeline supports 15 languages.}, booktitle = {SLTC 2016.

The main issue when automating proofs by induction is to discover essential helper lemmas. Our theorem provers use the technique theory exploration, which is a method to systematically discover interesting conclusions about a mathematical theory. We use the existing theory exploration system QuickSpec which conjectures properties for a program that seem to hold based on testing. The idea is to try to prove these explored conjectures together with the user-stated goal conjecture. By using this idea and connecting it with our previous work on Hip, the Haskell Inductive Prover, we were able to take new leaps in field of inductive theorem proving. Additionally, we have developed a benchmark suite named TIP, short for Tons of Inductive Problems, with benchmark problems for inductive theorem provers, and a tool box for converting and manipulating problems expressed in the TIP format. There were two main reasons to this initiative. Firstly, the inductive theorem proving field lacked a shared benchmark suite as well as a format. Secondly, the benchmarks that have been used were outdated: all contemporary provers would solve almost every problem. We have so far added hundreds of new challenges to the TIP suite to encourage further research. }, author = {Rosén, Dan}, year = {2016}, publisher = {Chalmers University of Technology}, address = {Göteborg}, }
