This demo presents LeXFlow, a workflow management system for crossfertilization of computational lexicons. Borrowing from techniques used in the domain of document workflows, we model the activity of lexicon management as a set of workflow types, where lexical entries move across agents in the process of being dynamically updated. A prototype of LeXFlow has been implemented with extensive use of XML technologies (XSLT, XPath, XForms, SVG) and open-source tools (Cocoon, Tomcat, MySQL). LeXFlow is a web-based application that enables the cooperative and distributed management of computational lexicons. . | LeXFlow a System for Cross-fertilization of Computational Lexicons Maurizio Tesconi and Andrea Marchetti CNR-IIT Via Moruzzi 1 56024 Pisa Italy @ Francesca Bertagna and Monica Monachini and Claudia Soria and Nicoletta Calzolari CNR-ILC Via Moruzzi 1 56024 Pisa Italy @ Abstract This demo presents LeXFlow a workflow management system for crossfertilization of computational lexicons.

LeXFlow is a web-based application that enables the cooperative and distributed management of computational lexicons. 1 Introduction LeXFlow is a workflow management system aimed at enabling the semi-automatic management of computational lexicons. By management we mean not only creation population and validation of lexical entries but also integration and enrichment of different lexicons. A lexicon can be enriched by resorting to automatically acquired information for instance by means of an application extracting information from corpora. But a lexicon can be enriched also by resorting to the information available in another lexicon which can happen to encode different types of information or at different levels of granularity. LeXFlow intends to address the request by the computational lexicon community for a change in perspective on computa tional lexicons from static resources towards dynamically configurable multi-source entities where the content of lexical entries is dynamically modified and updated on the basis of the integration of knowledge coming from different sources indifferently .
