Named Entity Recognition in Greek Web Pages

We describe the functionalities of the Hellenic Named Entity Recognition and Classification (HNERC) system developed in the context of the CROSSMARC project. CROSSMARC is developing technology for e-retail product comparison. The CROSSMARC system locates relevant retailers' web pages and processes them in order to extract information about their products (e.g. technical features, prices). CROSSMARC's technology is demonstrated and evaluated for two different product types and four languages (English, Greek, Italian, French). This paper presents the HNERC system that is responsible for the identification and classification of specific types of proper names (e.g. laptop manufacturers, models), numerical expressions (e.g. length, weight), and temporal expressions (e.g. time, date) in Hellenic vendor sites. The paper presents the HNERC processing stages using examples from the laptops domain.
