Widely regarded as the premier forum for reporting new research developments in these fields, the EP conference series has attracted scientists and engineers from leading academic, research, and industrial organizations around the world. The British Computer Society sponsored EP86, held in Nottingham, England and INRIA sponsored EP88, held in Nice, France. EP90 will be held at the National Institute of Standards and Technology (formerly the National Bureau of Standards) in Gaithersburg, Maryland, close to Washington, D. C., from Tuesday, September 18th through Thursday, September 20th, 1990. An associated exhibition will provide an opportunity for participants to see commercial and research systems in action. A broad definition of electronic publishing is adopted to encompass all aspects of computer-assisted preparation, presentation, transmittal, storage, and retrieval of documents. Topics include traditional paper-based documents; hypertexts and hypermedia; font design (both latin and non-latin alphabets); experience with structured document preparation systems; the intersection with and application of database systems and software engineering environments; the theoretical foundations for document models and systems; character, text and document recognition and manipulation; experience with standards; and documents with actively computed content. The proceedings of EP90 will be published by Cambridge University Press in its Electronic Publishing Series and a copy will be provided to each conference registrant.

Data are critical for theory formulation, for the development of practical applications in the language industries, and, in particular, for the evaluation of computational linguistics as a whole. Of particular interest from this point of view are recent activities concerned with the collection of text files, with the creation of lexical data and knowledge bases, and with the development of ways to increase the ability to reuse and share both data and tools. The results will increase the possibility and likelihood of cooperation across a broad range of areas in computational linguistics. This workshop will provide an open and informal forum within which these activities are discussed and their relationship to current research and development established. The results will be reported on during COLING-90. There are no restrictions on participation and there is no need to register specifically for the workshop.

Comments, reactions, even flames, welcomed. Lou Burnard, Assoc Ed, TEI ] ==== Date: Wed, 11 Jul 90 13:01:21 +0100 From: Stig Johansson Subject: How far SGML? Message-Id: <805*h_johansson@use.uio.uninett> Does everything have to be expressed through SGML? Is it good for all types of texts? Cf the recent book by Herwijnen (1990: 12): 'A tree representation can be used to describe many documents, but not all.' Even if SGML can be made to do the work, is it the best way for all texts and all types of textual features? For example, can it be used for the discourse transcription needed in a spoken corpus without cluttering up the text hopelessly? Why not try to convert a discourse transcription to SGML-type tagging? You will say - everything does not need to be keyboarded - there are possibilities of tag minimization - tags can be suppressed, etc. But we do want to be able to see the text simultaneously tagged for speaker overlap. stress, intonation, etc. You will say - but SGML is for the interchange format - it can be converted to/from a local format. The best thing would be, however, if we could have a usable interchange format or, at least, if we could minimize the difference between the interchange format and local formats. Otherwise, who will bother to use the interchange format? What I am really asking is: what harm does it do if we can find some simpler way of expressing, for example, intonation or word class? Finally, are we really sure that we can define in advance a grammar for textual features? This is what the DTD does (for a particular type of text). These are some of the questions that need careful consideration. Or am I just being stupid? Oslo 25 June 1990 Stig Johansson ============= From: Robert A Amsler Subject: Re: 3d note from SJ Re: Stig's concerns over whether SGML should always be used to represent all texts. There has been one category of material which from the beginning I have concluded should not be represented in SGML. From this category I believe one can abstract a general principle of what types of material are not best served in SGML garb. The category was programming language code. The reason was that since a compiler existed for such code, it was not only unnecessary to convert such material into SGML, it was outright harmful. Since then, I've come to conclude that DBMS loader stream information likewise should not be converted into SGML tagging. The reasoning is similar, that it is a formal language already, which is checked by its own software. In the case of database data, however, it was concluded that there might be another form of the information from which the database loader stream could be derived, and that this other format might itself be an SGML format. The general principle seems to be that what makes using SGML worthwhile is that software exists to make use of the format and software exists to validate the content of the format. Whenever other software exists for another format, the utility of SGML is lessened to the degree that this other software provides all the formal computational capabilities that SGML provides. However, there is another principle which should be stated. It is that most criteria which concern `readability' or `legibility' for human users of text are in fact derivable by software from less readable and less legible forms of information which are more useful to computers. Using a computer is a bit of a Faustian deal. We gain capabilities to do things, but lose a bit of the ability actually to understand the raw information from which these capabilities derive. ============================== ========================================================================= Date: Sat, 14 Jul 90 14:46:04 CST Reply-To: Text Encoding Initative public discussion list Sender: Text Encoding Initative public discussion list From: "Robin C. Cover" Subject: WHAT *SHOULDN'T* SGML DO? Re: Lou Burnard's "Subject: How far SGML?" Lou must have strong confidence in his friendships to have posted an exchange between Stig Johansson and Bob Amsler "without asking permission of either of them." Stig's queries ("Does everything have to be expressed through SGML? Is it good for all types of texts? ... Even if SGML can be made to do the work, is it the best way for all texts and all types of textual features?), in light of his subsequent comment, can be understood to ask whether KNOWLEDGE/ANALYSIS OF ALL KINDS *about* a text is best represented, in all kinds of texts, by SGML. Amsler's (posted) response in paraphrase (..."whether SGML should always be used to represent all texts...category of material") seems to focus on format and content, and validation of these. Stig's question seems to ask about propriety, economy, felicity. When I remind everyone that we need character-level and morpheme-level annotations on texts for representation of codices, textual criticism and linguistic analysis -- the question may be whether we WANT to use an SGML id marker for every character in the text, or whether we hand off some of the cross-referencing/parsing problems to applications software. I may be wrong in this interpretation of the exchange, but even if so, let me expand the question. Part of the issue seems to be: when should we let the applications do type-checking on the data (Amsler eliminates program code from SGML coding because compilers do the validation) and when do we declare detailed rules in a document DTD? If the applications already exist, the question is moot: they validate or they do not. In other cases, it's a fresh choice: new text being authored or structured, and new software process the encoded text. Do we require that the exchange format (SGML) validate *everything* that the local application controls with integrity checks? An example would be citations, whether of bibliographic data or internal references in classical literature. One *could* use SGML (the DTD, with entities, attributes and tags) in an authoring system to make sure that nobody ever typed "Sirach 23:30" (since Sirach chapter 23 has fewer than 30 verses). Is that the best way to validate the legitimacy of citations? Or is there a more economical way for ALL applications to validate citations, so that we can leave deep-level SGML structuring markup out of the interchange format? This is a more benign case than worries Stig, though (I think). He seems to be concerned with the important matter of representing knowledge and analysis of texts (not visible, surface features having to do with rules of containment) and questioning whether SGML always the best way to do this. Perhaps Bob answered adequately, and it's taking me a while to see how Bob's generalization answers all the questions. rcc ========================================================================= Date: Sun, 22 Jul 90 12:43:00 GMT Reply-To: Text Encoding Initative public discussion list Sender: Text Encoding Initative public discussion list From: Lou Burnard Subject: HyTime Meeting Announcement [ Extracted from MUSIC-RESEARCH bulletin board ] Music-Research Digest Sun, 22 Jul 90 Volume 5 : Issue 70 Today's Topics: meeting announcment for Hypertext and Time-based documents MuTeX - how to get it My MuTeX Request.

I have just received a slightly technical overview of the capabilities of the new text retrieval system from Information Dimensions, BASIS-PLUS, in which the following paragraphs caught my eye:- BASISPlus recognizes an extensive subset of Standard generalized Markup Language (SGML) to import and export marked up documents and intelligently comprehend and display document attributes identified by the markup. SGML is ... [brief description of markup concepts, usefulness of descriptive markup etc.] ... Documents stored in BASISplus contain text with embedded markup in the form of the BASISplus Generalised Markup Language (BGML). BGML is based on the identification of document structure using descriptive markup. BGML enables BASISplus to recognize the attributes of the text stored in the BDIF format. BGML is derived from and is consistent with SGML. At presentation time, the BASISplus Markup and Style Guide is referenced to determine how to format the text and where to find the external entities. It contains the definitions for markup elements, entity references and processing procedures. A standard set of markup elements is supplied with BASISplus and users can create customized markup elements. Only the rules need to be edited; documents are unchanged and are not exposed to editing errors. BASISplus requires all the definitions of the markup elements and entity references to be precompiled into a Markup and Style Guide [...] The Markup and Style Guide is a BASISplus repository contaioning specifications for: - Converters used to import and export documents [other formats mentioned include Revisable Form WP, Flatfiles, DDIF Compound Docs, DIF ] - Parsers used to locate 'context units' in the text of a document - Presenters used to prepoare a document for viewing - Markup language declarations for documents that contain markup elements and entity references used for descriptive markup If this is only half as good as it sounds, it's worth a second look. OUCS is currently negotiating with Info Dimensions to upgrade our current Basis systems to BasisPlus. I'll keep you posted... Lou Burnard
