A Novel Approach to Automatic Gazetteer Generation using Wikipedia
نویسندگان
چکیده
Gazetteers or entity dictionaries are important knowledge resources for solving a wide range of NLP problems, such as entity extraction. We introduce a novel method to automatically generate gazetteers from seed lists using an external knowledge resource, the Wikipedia. Unlike previous methods, our method exploits the rich content and various structural elements of Wikipedia, and does not rely on languageor domainspecific knowledge. Furthermore, applying the extended gazetteers to an entity extraction task in a scientific domain, we empirically observed a significant improvement in system accuracy when compared with those using seed gazetteers.

In this paper, we propose an approach for automatic generation of novel intrusion signatures. This approach can be used in the signature-based Network Intrusion Detection Systems (NIDSs) and for the automation of the process of intrusion detection in these systems. In the proposed approach, first, by using several one-class classifiers, the profile of the normal network traffic is established. ...

متن کاملMining Wikipedia Article Clusters for Geospatial Entities and Relationships
We present in this paper a method to extract geospatial entities and relationships from the unstructured text of the English language Wikipedia. Using a novel approach that applies SVMs trained from purely structural features of text strings, we extract candidate geospatial entities and relationships. Using a combination of further techniques, along with an external gazetteer, the candidate ent...
