Abstract Details

2006, Master of Computer Science, Miami University, Computer Science and Systems Analysis.
Some text documents, legacy documents in particular, do not format sections of text containing tables. Documents like these are not as readable as they could be since the columns are not aligned. Non aligned columns prevent the reader from seeing the important patterns in the text. This thesis presents algorithms to help insert table formatting into free text. This algorithm parses the text to identify common syntactic patterns such as dates, dollar amounts, and times. Pattern matching techniques are then used to identify models of what type of data each column should contain. These models are called templates. Ambiguities often exist. These ambiguities make it necessary to rank the alternative templates and their associated tables. This thesis focuses on evaluating the candidate templates and associated tables to rank the different alternatives. The scoring function attempts to mimic the process that a human might go through when performing the same task. The effectiveness of the scoring is evaluated on a set of tables that have appeared in real electronic feeds.
