This volume constitutes the refereed proceedings of the 7th International Workshop on Fuzzy Logic and Applications held in Camogli, Genoa, Italy in July 2007. The 84 revised full papers presented together with 3 keynote speeches were carefully reviewed and selected from 147 submissions. The papers are organized in topical sections on fuzzy set theory, fuzzy information access and retrieval, fuzzy machine learning, fuzzy architectures and systems; and special sessions on intuitionistic fuzzy sets and soft computing in image processing. WILF 2007 hosts four special sessions, namely the Fourth International Meeting on Computational Intelligence Methods for Bioinformatics and Biostatistics (CIDD 2007), the Third International Workshop on Cross-Language Information Processing (CLIP 2007); Intuitionistic Fuzzy Sets: Recent Advances (IFS), and Soft Computing in Image Processing (CLIPS). These special sessions extend and deepen the main topics of WILF.
