PhiloLogic is a "primary full-text search, retrieval and analysis tool" developed by the University of Chicago. PhiloLogic leverages the "wide array of XML data specifications and the recent deployment of basic XML processing tools provides an important opportunity for the collaborative development of higher-level, interoperable tools for Humanities Computing applications". Recognizing that the TEI community does not suit a one-size-fits-all approach, PhiloLogic focuses on the development of "specialized, interoperable tools" that can be implemented for end-user applications in a cost-effective manner. PhiloLogic is committed to the open source development of these applications: drawing on a wide range of technical abilities and expertise that is "not well supported by the commercial sector".
