”Automatic event extraction from fulltext resources is a combination of human language technology (HLT) and semantic web technologies. It can also be done on the base of purely statistical means with minimal linguistic knowledge”. This thesis introduces a semi-automated method based on the HLT approach. The method uses an existing information extraction system called ANNIE, A Nearly-New Informa...

This work analyzes research gaps and challenges for Web-scale Information Extraction and foresees the usage of Linked Open Data as a groundbreaking solution for the field. The paper presents a novel methodology for Web scale Information Extraction which will be the core of the LODIE project (Linked Open Data Information Extraction). LODIE aims to develop Information Extraction techniques able t...

with the increased confidence in the use of the internet and the world wide web, the number of electronic commerce (e-commerce) transactions is growing rapidly. therefore, finding useful patterns and rules of users’ behaviors has become the critical issue for e-commerce and can be used to tailor e-commerce services in order to successfully meet the customers’ needs. this paper proposes an appro...

Nature of Web information is dynamic and irregular that’s why it is difficult to search and integrate information from the Web. The biggest task in making WWW data accessible to users/agents is extracting the data from Web pages. We take advantage of information in existing Web pages to creating structured data semi-automatically. Extraction of information from semi-structured or unstructured d...

Data cleaning is a vital process that ensures the quality of data stored in real-world databases. The process of identifying the record pairs that represent the same entity (duplicate records), commonly known as record linkage, is one of the essential elements of data cleaning. Digital government serves as an emerging area for database research, such as database management, data integration, da...

In this paper, a workflow was developed to enable efficient data extraction from web and integration them with the cooperation of web developers and data professionals who specialized in a certain field. This paper introduces how we applied the workflow to build Linked Data for “LODAC Museum”, a dataset on museum collection data in Japan.

This paper is concerned with the problem of structured data extraction from Web pages. The objective of the research is to automatically segment data records in a page, extract data items/fields from these records and store the extracted data in a database. In this paper, we first introduce the extraction problem, and then discuss the main existing approaches and their limitations. After that, ...

This paper shows how Semantic Web technologies enable the design and implementation of advanced, personalized information systems. We demonstrate by means of an example application how personalized content syndication can be realized in the Semantic Web. Our approach consists of two main parts: The web data extraction part, providing the information system with real-time, dynamic data, and the ...
