5 Formal Model of Table Structure Knowledge Sources
Modern office applications such as MS Office, Open Office, Lotus SmartSuite provide
effective software tools for creating and maintaining documents, the contents of
which can be organized using tabular structures with the ability to convert these
documents into various formats. But unfortunately, the format of the documents
supported by these packages is different: MS Office—doc, Open Office—sxw, Lotus
SmartSuite—lwp. In addition, due to the dominance of the Windows desktop market
with the MS Office suite, developers of alternative office suites are trying to add
support for the doc format. MS Office. But today, support for the doc format. is
limited. At the same time, all office suites provide excellent support for the HTML
format, both for processing documents and for saving processing results, which
allows expressing the contents of documents of various formats in HTML markup
while maintaining the structure and without loss of formatting.
Using HTML to represent the contents of documents provides a syntax-compatible
format for exchanging documents between software systems.
Recently, HTML has become a subset of the XML language, which has a wider
set of tools for ensuring compatibility at the level of document syntax, but to date,
XML support is not provided by all electronic document processing packages. Thus,
it seems appropriate to use tabular models of the HTML language to develop a formal
model of the sources of knowledge of the table structure. Further, taking into account
the provisions of the integrated tabular model (ITM) of HTML, a formal model of the
sources of knowledge of table structures will be developed by adding the necessary
functionality to analyze the sources of knowledge of table structures in an integrated
table model of the HTML hypertext language.
Imagine SKTS as follows:
TC =< TZ,TB
g
>,
(13)
where: TC—SKTS; TZ—SKTS header; TB
g —SKTS dataset.
According to the provisions of KTM HTML, more than one data set can be defined
within one SKTS, then TB
g mathematically it can be represented by the formula:
TB
g
= {TB 1 , . . . , TB β },
(14)
where β—the TB number in SKTS.
Given that the number of TB greater than 1 is used solely to provide portioned
downloading of SKTS content via the Internet to a client computer, which is irrelevant in the context of the ongoing research, in the future, if this does not lead to
