Information retrieval research for informal conversational settings differs in important ways from the more traditional goal of document retrieval. The goal of this research is to build an information retrieval test collection from informal conversational messages and to demonstrate the use of that collection to compare the retrieval effectiveness of some information retrieval systems. The test collection is based on the Linguistic Data Consortium's collection of more than 8,000 English SMS (Short Message Service) conversations, which contain more than 120,000 individual messages. The collection is described, followed by a description of the processes for creating and collecting topics, performing relevance judgments, and establishing baseline results. The findings indicate that traditional approaches for building information retrieval test collections can reasonably be applied to preclustered SMS conversations, but that the process of creating relevance judgments is somewhat more challenging and thus the reliable detection of differences in system effectiveness is somewhat more complex.
