This paper is an introduction to using the Treebank Semantics Parsed Corpus (TSPC) and its online interface.The TSPC is a collection of English with hand worked tree annotation for approaching half-a-million words.The annotation gives a resource of general use but is notable as content to feed a calculation of meaning representations for insights beyond surface syntax.The online interface has functionalities of search, summary and visualisation for presenting the source files of the corpus.The paper ends with a case study demonstrating how to access data for a language education task, with pinpoint insights gained because of the detailed analysis offered by the corpus.
