Date of birth extraction using precise shallow parsing
2010
Document Recognition and Retrieval XVII
Preserved Fulltext
This paper presents the implementation and evaluation of a pattern-based program to extract date of birth information from OCR text. ...
Although the program finds data of birth information with high precision and recall, this type of information extraction task seems to be negatively impacted by OCR errors. ...
Our method of evaluation for finding date of birth will mirror the standard method in most information extraction experiments. The abbreviation DOB stands for "date of birth". ...

This paper deals with the problem of extracting semantic knowledge in the production of ER models from natural language specifications. ...
Earlier research has shown that syntactic heuristics produced good results in identifying the relevant and correct results of the ER elements in terms of recall and precision. ...
The parser used here is Memory-Based Shallow Parser (MBSP) [4, 17] . The results produced is then parsed through a semantic analyser for the semantic analysis. ...

We show the practical relevance of our approach by extensive experiments with our prototype system Leila. might be interested in extracting all pairs of a person and her birth date (the birthdate-relation ...
In this paper, we show that this approach profits significantly when deep linguistic structures are used instead of surface text patterns. ...
For instance, for the birthdate-relation, the examples can be given by a list of persons with their birth dates. • A counterexample. ...

Relations of interest are identified by parsing the sentences and extracting dependency graph fragments, which are then ranked to determine which of them are most closely associated with the seed relation ...
We call the sets of associated relations relation theories. The quality of the induced theories is evaluated using human judgements. ...
Finally, a large background corpus of parsed sentences from Wikipedia was used to rank candidate relations. We will use the marriage relation as a running example. ...
