....and improper references. The approaches from this line of research that are closest to CREAM is the SHOE Knowledge Annotator , WebKB, and the MnM annotation tool. The SHOE Knowledge Annotator is a Java program that allows users to mark up web pages with the SHOE ontology. The SHOE system [26] defines additional tags that can be embedded in the body of HTML pages. The SHOE Knowledge Annotator is rather a little helper (like our earlier OntoPad [12] 6] than a full fledged annotation environment. WebKB [27] uses conceptual graphs for representing the semantic content of Web ....

The emergence of standards for structural knowledge representation, like DAML OIL and RDF, should allow researchers to o er better services in information retrieval: semantic requests [2] semantic document indexing, etc. However, ordinary users in the semantic web do not access directly to ....

....extensive topic would be very much beyong the scope of this paper. We have therefore selected a limited number of representative projects in order to compare our work with the state of the art in the field. No completeness of this survey is intended. SHOE SHOE ( Simple HTML Ontology Extension , [13]) is an extension of HTML in which one can define ontologies and use these ontologies to annotate HTML pages. There are a number of important differences with WebMaster s notion of ontology. Firstly, WebMaster derives type membership on the basis of required properties as stated in rules while in ....

....unfortunately, it lacks a standardised way to link them with an abstract description of their semantics. There are many proposals that aim at solving this problem. They usually rely on annotating web pages with instances of ontologies that are usually written in languages such as DAML [1] SHOE [17] or RDF Schema [16] Unfortunately, there are very little annotated pages if we compare them with non annotated pages. As of the time of writing this article, the DAML crawler (www.daml.org crawler) reports 17,019 annotated web pages, which is a negligible figure if we compare it with 2,110 ....

....metric is calculated by passing through the hypernym links, i.e. isa links, through WordNet. More recent proposals for Web based information retrieval build on ontology based information agents which search for, maintain, and mediate relevant information on behalf of their users or other agents [40, 30, 45]. Sim and Wong [30] have developed a society of software agents: Query processing agents which assist users in selecting Web pages, information filtering agents for actual information retrieval, and information monitoring agents to report changes. Query processing agents search for URLs using ....

....in a generic way and provide a commonly agreed understanding of a domain, which may be reused, shared, and operationalized across applications and groups. Thus, ontologies are well suited for enabling communication between agents in general, including software agents as well as human agents [4]. However, because of their size, their complexity and their formal underpinnings ontologies are still far from being a commodity. Developing ontologies is a non trivial task. We relied on a well known ontology engineering environment accompanied by a methodology for ontology development. ....

.... Wrappers are also not likely to be automatically generated [ACHK93, EW94, DEW97] The reason is that there is no uniform mechanism to describe the semantics of information contained in Web pages [TNC 96] Attempts to overcome these problems try to enhance web pages by semantical information [LSRH97] or agree on micro languages more powerful than HTML [Fuc96] In both approaches human design is essential. Therefore rapid prototyping of web applications is a prerequesite for the success of this technology. Recently, logic programming which supports rapid prototyping is extended and enhanced ....

....transparency, since the user cannot foresee in which class the relevant documents lay. A more ambitious approach to enhance precision is to annotate Web pages with special HTML tags which convey the page s classification e.g. SHOE system (Simple HTML Ontology Extension) Luke et al. 1996, Luke et al. 1997] 4 , GDA system (Global Document Annotation) Utiyama Hasida 1997] 5 . The user determines the page s classification based on some available ontology, indicated in the page s heading. Two major drawbacks can be identified here: 1) the index bases are constrained to pages marked with each ....

....anyknowledge base attempting to describe it could ever be complete. In an attempt to deal with these issues, wehave designed a language named SHOE, for Simple HTML Ontology Extensions. SHOE is one of the first languages that allows ontologies to be designed and used directly on the World Wide Web [25]. In this paper we describe work that influenced SHOE, present an overview of the language, describe its syntax and semantics, and discuss how SHOE addresses the issues posed in this introduction. We then discuss the problem of implementing a system that uses SHOE, describe some tools that enhance ....
