With a total of six patents to his name, De Saeger is recognized for his innovative approaches to solving complex problems in data management.

Latest Patents

Among his latest patents are the "Text Matching Device and Method" and the "Text Classification Device and Method." The objective of these inventions is to provide a system for automatically and reliably collecting information belonging to a given category and matching the information appropriately in a timely manner. The text classifying device analyzes the dependency of collected texts through a morpheme analyzing unit and a dependency analyzing unit. A problem report collecting unit specifies a core consisting of noun and predicate in a text based on the dependency relation of the text. By using a combination of noun classification (trouble/non-trouble) and predicate classification (excitatory/inhibitory), the device classifies the text into a problem report or the rest through a method referred to as core-based matrix. Additionally, a matching device matches problem reports and support information collected by the problem report collecting unit and support information collecting device using a method known as co-occurrence core matrix.

Another notable invention is the "Non-Factoid Question-Answering System and Method." This system is capable of appropriately answering non-factoid questions. It responds to a question by extracting answer candidates from an object document storage unit, recognizing causal relation expressions included in the extracted candidates, and determining the relevance of these relations as answers. The system generates a feature vector related to the combination of the question and the searched answer candidate, calculating a score that indicates the correctness of the answer candidate. Ultimately, it outputs the answer candidate with the highest score as the response to the question.
