HTML table wrapper based on table components

Tables are a model for data representation in the internet. Many approaches to harvesting table data are executed by doing the copy-paste. However, this method will be a problem if there is a huge amount of tables and they come from many internet sources. This paper presents an approach to prepare the table area and to wrap or extract table components in cells and property from HTML tables. This paper discusses how the approach works by testing Algorithms 1, 2, and 3. Algorithm 1 is used to determine the actual number of columns and rows of the table, and Algorithm 2 is used to determine the boundary line of the property. At the end of the process of extraction, Algorithm 3 is implemented to get content of the table. Tests were conducted at 100 tabular HTML format. The result of F-measure for Algorithm 1 is 100.00%, for Algorithm 2 97.67% and for Algorithm 3 94.91%.

HTML Extraction Algorithm Based on Property and Data Cell

The data available on the Internet is in various models and formats. One form of data representation is a table. Tables extraction is used in process more than one table on the Internet from different sources. Currently the effort is done by using copy-paste that is not automatic process. This article presents an approach to prepare the area, so tables in HTML format can be extracted and converted into a database that make easier to combine the data from many resources. This article was tested on the algorithm 1 used to determine the actual number of columns and rows of the table, as well as algorithm 2 are used to determine the boundary line of the property. Tests conducted at 100 tabular HTML format, and the test results provide the accuracy of the algorithm 1 is 99.9% and the accuracy of the algorithm 2 is 84%.
