Problems solved by technology

One problem is that due to the high complexity of the semantic relationship of the table, it is difficult to design an automatic method that can completely correctly identify the success. For example, the literature [7]

[0039] detailed description

[0040] Such as figure 1 As shown, some commonly used tables on the Internet and reference documents are used as the explanatory object, VC++ is used as the development language, and the TableToSS system developed by the inventor is used as the basis. According to the principle of the HTML table semantic context analysis method disclosed in the present invention And the implementation scheme is:

[0041] Step 101: Create a table coordinate system.

[0042] The following definition is given with reference to the relationship theory method:

[0043] Definition 1: Given a set of domain D 1 , D 2 ,..., D n , Their Cartesian product is D 1 ×D 2 ×…×D n ={d 1 , D 2 ,...,D n )|d i ∈ D i , I=1, 2,..., n}, and each domain D i The domain name and Cartesian product of is evenly written in some two-dimensional rectangular grids neatly arranged in the horizontal and vertical directions, and each row of each grid is the same height, and each column is the same width. T...

Abstract

The invention discloses a hypertext markup language (HTML) table semantic analysis method, which is applied to the retrieval of a webpage document. A semantic venation relation of an HTML table can be acquired according to geometric position relations among different cells in the HTML table. The cells are described by defining a table coordinate system and a table matrix, and attributes in the table and attribute dereferencing characteristics are determined by defining a column or row assembly unit and taking the column or row assembly unit as an analysis object. An action scope of each attribute is set and the attribute and an attribute dereferencing recognition rule are established by analyzing the geometrical position relations among the cells, so that table cells can be traversed by the table matrix and the relations among all the cells can be established to form a table semantic venation tree and provide supports for the retrieval of the document. The method accords with the tabulation and reading habits of people; the algorithm is simple; and only a table content tree needs recording, but is not required to be developed to form a body node or database data, so that the memory space is greatly saved.

Description

technical field [0001] The invention relates to a semantic analysis method of an HTML table, which can be especially applied in the retrieval of webpage documents, and an association relationship can be established according to the geometric positional relationship between different cells in the HTML table, so as to establish a data content in the table semantic context. Background technique [0002] Tables are a common means for people to express semantic relations in a structured way, which can effectively describe specific instances of one or more classes, so tables are widely used in various documents. With the development of Internet technology and the popularization of applications, tables constructed in forms such as hypertext markup language (HTML) are widely used in web pages. For humans, it is relatively clear to use tables to express semantic relationships, but due to human intelligence, simplicity, and irregularity, many tables contain very complex semantic rela...
