\begin{abstract}
Several tasks which include text documents processing, such as text alignment,
format
conversions or information retrieval are heavily affected by the state of the
original documents.

Cleaning tasks include
removing page breaks, page numbers, headers and footers; finding section titles
and boundaries; removing footnotes and normalizing paragraph notation and
Unicode characters. The process is guided with the help of declarative objects
such as ontologies and configuration files.

\section{Motivation}

Text processing (and particularly book alignment) are tasks whose 
performance is often negatively affected by:
\begin{multicols}{2}
\begin{itemize}
    \setlength{\itemsep}{0pt}
    \setlength{\parskip}{0pt}
%    {\setlength{\itemindent}{50pt}
    \item Page structure
    \item Section titles
    \item Section boundaries
    \item Section numbers
    \item Footnotes \newpage
    \item headers
    \item footers
%    }
    \item Paragraphs
    \item Character encoding etc.
\end{itemize}
