1 Introduction
</SectionTitle>
    <Paragraph position="0"> Language Technology (LT) resources are time-consuming and expensive to develop, and applications rarely have the luxury of calling upon resources specially designed for the task at hand. For LT applications in developmental biology such as robust interfaces to anatomically-indexed gene expression data and text mining tools to assist in building such databases, resources already exist in the form of anatomical nomenclatures for several model organisms including mouse, zebrafish, drosophila and human. (Others may follow.) These nomenclatures have been developed by biologists for biologists, to record in a clear, intuitive and structured way the structures that can be distinguished at each stage of an embryo's development. The challenge for LT applications in developmental biology is to stretch them to serve other purposes as well.</Paragraph>
    <Paragraph position="1"> In this paper, we describe how we have taken one of these anatomical nomenclatures (mouse) and extracted from it a new resource to facilitate free text access to anatomically-indexed data. The techniques we have used are applicable to anatomical nomenclatures for other model organisms as well.</Paragraph>
    <Paragraph position="2"> The paper is organised as follows: In Section 2, we describe the Mouse Atlas, which is the particular context for the interface we are developing. Section 3 describes what we are doing to reduce the amount of effort a user has to expend in specifying anatomical structures of interest to them. In Section 4, we describe how what we did to reduce user effort also serves to provide a clearer display of the results of searching. Then in Sections 5 and 6, we describe what we are doing to increase the precision and recall of user queries.</Paragraph>
