Data Cleaning Utilizing Ontology Tool

Jing Ting Wong, Jer Lang Hong
2016 International Journal of Grid and Distributed Computing  
Before data cleaning is carried out, we first need to extract out the data from deep webpages. To do this, we use WISH wrapper to extract data.  ...  On the other hand, Stefan and Fabian [3] uses ontology for Data Quality Management and Julian et. al., [7] uses an ontology based approach for data cleaning which is able to scale across big data in  ...

2022 arXiv   pre-print
As an application of , we augment the INTERSPEECH 2021 DNS challenge by sampling audio files from a new batch of data of 20K clean speech clips from Librivox mixed with noise clips obtained from Audio  ...  However, this approach leads to regressions due to the lack of training/testing on representative customer data. Moreover, due to privacy reasons, developers cannot listen to customer content.  ...  Since real-world applications contain speech mixed with noise, most deep learning methods rely on synthetic data that mix clean and noisy speech [4] .  ...

Furthermore, it retrieves facts from sources where the data is not directly described in terms of the query ontology.  ...  Instead, its ontology can be translated from the query ontology using mapping axioms. In our solution, we use the concept of source relevance to summarize the content of a data source.  ...  We collected city specific data of about 70,000 cities from this source. The data is fairly clean and we have converted it to OWL with simple scripts.  ...
