The Web provides a seemingly endless resource of information. The number of Web pages has recently trespassed one trillion, and its size is estimated to be several million terabytes. If a book contains 5 megabytes of data, we would have to print 200 billion books to store the Web – and build 6000 Libraries of Congress for them. And yet size is not everything. The crucial question is how useful that data is. And while the Web can answer many everyday questions already, it fails quickly in the face of more advanced information needs.
Complex information needs may appear in many different domains : researchers in the life sciences will want to find known proteins that inhibit atherosclerosis. Patent officers will want to find scientific papers that inspired a patent application. Economists will want to study effects of reforms (or their absence) on the economy of a country (or the morale of its inhabitants). These are information requirements for which the Web might contain answers. Yet, these answers are often hard, if not impossible to find. Thus, we find ourselves caught in a paradox: The amount of information on the Web is steadily growing, yet its usefulness is not.
The reason for this paradox is that the information on the Web mostly takes the form of natural language. Computers, however, are blind to the semantic 3 dimension of language. If computers are to help us find information, then that information has to be in a form that a computer can “understand”. That form is usually an ontology. An ontology, in its most general sense, is a structured collection of real-world knowledge with attached semantic rules. An ontology contains knowledge in such a form that a computer can answer queries on it, check it for consistency, and reason on it. Consequently, ontologies find applications in numerous domains, such as machine translation, word sense disambiguation, document classification, question answering, query expansion, and information integration.
Most notably, ontologies provide a way to attack the problem of “Big Data”: Data mining, visual analytics, and data-driven decision making systems can all benefit from semantic knowledge. Ontologies can provide,e.g., the categories for clustering, the dimensions for visualization, and the common sense for making decisions. Given the wealth of unstructured data on the Web on one hand, and the usefulness of ontologies on the other hand, recent years have seen considerable efforts to extract ontological knowledge from Web data.
With the Seda project, we propose to push this search even further. Our goal is to make even more information semantically accessible to machines. This goal can be pursued along numerous dimensions: Information Extraction, Crowd Sourcing, Data Mining, Text Annotation, Ontology Mapping, and Manual On- tology Design all come to mind. The Seda project has to concentrate on certain axes. The key insight that defines the thrust of Seda is the exploitation of existing structured data: Nowadays, structured information is already available in the form of the existing ontologies. Thus, the search for new structured knowledge can now be fuelled by the structured knowledge that is already available. This is the twist that guides the research in Seda. We will exploit this philosophy along 3 dimensions:
- 1. By Information Extraction: The classical tool of information extraction can now be helped by the information that is already in structured form in existing ontologies.
- 2. By knowledge linking: Information in the form of text, Web Services, or Web forms can now be semantically interpreted by linking it with an existing ontology.
- 3. By knowledge mining: The information in an existing ontology can be used for reasoning, thus deriving new pieces of information from within the data.
In addition, Seda will conduct basic research on the foundations of ontological knowledge representation.
He continued as the leader of the Otto Hahn Research Group "Ontologies" at the Max-Planck Institute for Informatics in Germany.
Fabian taught classes on the Semantic Web, Information Extraction and Knowledge Representation in France, in Germany, and in Senegal. With his students, he works on information extraction, rule mining, ontology matching, and other topics related to large knowledge bases. He has published around 70 scientific articles, among others at ISWC, VLDB, SIGMOD, WWW, CIKM, ICDE, and SIGIR, and his work has been cited more than 8000 times. He has won 3 best paper awards or runner ups and the ten year test of time award of the WWW conference.
