This book constitutes the refereed proceedings of the 7th International Conference on Computational Linguistics and Intelligent Text Processing, CICLing 2006, held in Mexico City, Mexico, in February 2006.

The 43 revised full papers and 16 revised short papers presented together with 3 invited papers were carefully reviewed and selected from 176 submissions. The papers are structured into two parts and organized beyond in topical sections on computational linguistics research: lexical resources, corpus-based knowledge acquisition, morphology and part-of-speech tagging, syntax and parsing, word sense disambiguation and anaphora resolution, semantics, text generation, natural language interfaces and speech processing; and intelligent text processing applications: information retrieval, question answering, text summarization, information extraction and text mining, text classification, as well as authoring tools and spelling correction.
