Abstract
With the emergence of the e-Catalog, there has been an increasingly wide application of commodities query in distributed environment in the field of e-commerce. But e-Catalog is often autonomous and heterogeneous, effectively integrating and querying them is a delicate and time-consuming task. Electronic catalog contains rich semantics associated with products, and serves as a challenging domain for ontology application. Ontology is concerned with the nature and relations of being. It can play a crucial role in e-commerce as a formalization of e-Catalog. User personalized catalog ontology aims at capturing the users' interests in a working domain, which forms the basis of providing personalized e-Catalog services. In this paper, we present an ontological model of e-Catalogs, and design a semantic personalized e-Catalog service system (SPECSS), which achieves match user personalized catalog ontology (UPCO) and domain e-Catalog ontology (DECO) based on ontology integrated and focus on four key technologies: user personalized catalog ontology generation, domain and local e-Catalog construction, semantic match between them and e-Catalog semantic query system based on heterogeneous catalog database.

We present an ontological model of e-Catalogs, and design a semantic personalized e-Catalog service system (SPECSS), which achieves match user personalized catalog ontology (UPCO) and domain eCatalog ontology (DECO) based on ontology integrated and focus on four key technologies: user personalized catalog ontology generation, domain and local e-Catalog construction, semantic match between them and eCatalog semantic query system based on heterogeneous catalog database
When we need to apply it to specific areas, we can build the corresponding catalog ontologies in the fields according to the general user personalized catalog ontology framework, and combine users’ personalized request with e-Catalog semantic queries, which can upgrade users’ interest from the level keyword-based to a knowledge-based level, and link with keywords by semantics, because the UPCO describes users’ interest in customers’ view, and is closer to the users’ real thoughts
Summary
Electronic catalog is the aggregation of the static WWW pages including product information which is an essential component in e-commerce scenarios. As the number of Internet users and the number of accessible Web pages grow, it is becoming more and more difficult for users to find documents among e-Catalogs that are relevant to their particular needs. A semantically rich user model and an efficient way of processing semantics are the keys to provide personalized eCatalog services [4]. In view of the existing limitations, we develop a personalized ontology based on user model, called user personalized catalog ontology, which has the same level of semantics as domain ontology.
