A linguagem especificada em um DTD, como definido pelo padr ao SGML, possui uma propriedade importante: apenas a estrutura l ogica de um documento e descrita, n ao sendo dada nenhuma informac ao a respeito da semantica de apresentac ao do documento [2]. Deste modo, para um livro, por exemplo, e dada a estrutura de seus cap itulos e sec oes, mas nada e definido a respeito do formato de apresentac ao das p aginas, colunas, ou qual o tipo do caractere utilizado. Isso significa que e de responsabilidade da aplicac ao que processa um documento ....

....the text components. The challenge of such systems is to retrieve the document content in spite of the possibly bad quality of images and the uncertainty of the generic model, and to incorporate text reading into structure analysis. The key concept in document analysis is that of structure [5,6]. It gives the information to guide the system s actions. Often, document analysis consists in finding the high level structure in the document in terms of a hierarchy of physical and logical objects. At this level, the layout components, dealing more with the visual perception of the document, ....

....is an acronym for document management in Portuguese. The other characteristic feature of GDOC that is discussed here is its document model. GDOC handles structured documents, like those in other document models as ODA (Office Document Architecture) and SGML (Standard Generalized Markup Language) [5,10]. What is specific to GDOC is that documents are stored in a combination of relational database tables with HTML strings, in such a way that enables a relational database application to handle the document structure and a WEB browser to present and edit a document. The article is organized as ....

....of documents. Requirements relative to other system functions like document workflow or authorization are not discussed here. The main requirements of a document storage system for the considered field of application are listed below: Structured documents are managed. A structured document [5] is characterized not only by its content, but also by its logical structure. An example of logical structure of a document is the division of a document in components like title paragraphs and attributes. Logical structuring helps to increase the understanding of the document content by the ....

....to their parent nodes. For example, the leaf below a node u labeled by title would be the text content of the title structure represented by node u. This kind of databases can originate from explicit representations of document structures conforming for example to standards like ODA and SGML [Bro89] In our model a search is used for locating subtrees of the database. This means that a search can either return complete documents or their parts. 7.2 Querying with inclusion patterns In this section we show how tree inclusion with logical variables can be applied to querying structured text ....

....of hypermedia documents, since document presentation is beyond the scope of document management systems. A standardized means for the representation of logically structured text documents and hypertext and hypermedia documents is provided by the Standard Generalized Markup Language (SGML) [30, 136] and HyTime, an application of SGML. Another ISO standard for document representation to be mentioned here is the Office Document Architecture (ODA) and Interchange Format (ODIF) 82, 7] The Document Model 12 ODA makes use of SGML for representing the structure of documents [148] 2.3.2 SGML ....

....ambiguities. It is obvious that to correctly exploit this context, it is necessary to have properly de ned the document structure, including the logical chaining of dioeerent entities and their layout presentation on the document physical supports. This growing interest for document structuring [2, 7] is now emphasized by international standards like oda [6] and sgml [5] A lot of work has been done in this eld during the past decade [3, 12] Nowadays in optical reading, several systems try to take into account the document structure as a fundamental context for the recognition. Among the ....

....quite common: dictionaries, reference manuals, yearly reports etc. are typical examples. In recent years, research into systems for writing structured documents has flourished: see, e.g. AFQ89b, AFQ89a, Fur89, Qui89] for recent surveys of the field. The SGML and ODA standards (see [Jol89, Bar89, Bro89] have further increased the interest in the area. The Helsinki Structured Text Database System (HST) is an environment for the writing and editing of structured documents. The system uses context free grammars for modelling the structure of documents. The HST system differs from previous work in ....

....the importance of maintaining the structure of a document at all stages of editing, storage and transmission. The Office Document Architecture (ODA) and the Standard Generalized Markup Language (SGML) are two international standards for the representation and interchange of structured documents [8]. ODA has close links with the office automation and communications world. This reflected particularly strongly in its content architectures. Therefore, ODA is commonly used as the standard output format of a document understanding system. SGML is more closely linked publishing and printing ....

The underlying structure presents a complex organization, where several character fonts are mixed and the layout appears in an unconstant manner, with photographs, graphics, arrays and text areas within. A growing interest for document structuring [2, 8] is now emphasized by international standards [7, 6] and a lot of work has been done in this eld during the past years [4, 12] and several optical reading systems try now to take into account the structure of the documents as a fundamental context for the recognition such as [10, 11, 13, 5] ....

Recent surveys of the field are [AFQ89a, AFQ89b, Qui89, Sal92] The interest in the area has led to the creation of several document standards, e.g. ODA and SGML [Hor85, HKN89, Jol89, Bar89, Bro89, App91] In this section we give an example of structured document preparation and also outline the goals of the thesis. 3.1 Grammars for structure description One way to describe the structure of a document is to use context free grammars [BR84, CIV86, QV86, GT87, FQA88, KP91] Thus, in ....

Recent surveys of the research concerning structured documents are [AFQ89, Qui89] The interest in the area has led to the creation of several document standards, of which the best known are Open Document Architecture (ODA) and Standard Generalized Markup Language (SGML) [ODA89, SGM86, Bro89, Gol90]. The common way to describe the structure of a document is to use contextfree grammars. It is typical to use regular expressions on the right hand sides of the productions of the grammar. For example, the following might describe the simplified structure of a dictionary entry: Entry Headword ....
