....systems providing tools to browse and annotate discussion messages and threads are out of the scope of this paper. Next we discuss about noncommercial document centered systems where learners are able to annotate web based documents. The first generation of annotation tools such as ComMentor [13] and Group Annotation Transducer [15] required installation of platform specific client side software. The second generation allowed annotation of any document on the Web. Systems like CoNote [2] showed annotations embedded in the document, at the nearby position that they were made. We see two ....

....requirements of document models have already been discussed in section 3.2. An annotation model dealing with these requirements is currently under investigation by [4] Two specific kinds of annotations are of particular interest to dockets: seals of approval (SOAPs) and usage indicators [26]. SOAPs areusedby experts to give ratings to documents. Reviewing with dockets based on enumeration type properties is similar to SOAP assignment. Usage indicators measure a document s value byshowing how often it has been read and possibly by whom. Thus, they are similar in purpose as traces ....

....of any useful context. Thus robust anchors that allow annotations to remain associated with the correct portion of the document even if the document is modified are crucial. A number of existing systems have methods for locating positions within a document when the document changes [5] 6] 7] 9] 10][11][13] While these algorithms are robust to varying degrees, none of them take users expectations into account. The primary contribution of this paper is to introduce Keyword Anchoring, a robust anchoring method we designed based on what users expect to happen to annotations when the document ....

....easily be used in conjunction with these methods to provide additional robustness that may better meet user expectations. 7.2 Content Information Using only information about the content of the anchor text selected by the user makes the robust anchors independent of document format. ComMentor [11], Annotator [7] and CritLink [13] all support annotation on web documents and use content information for robust anchoring. ComMentor and Annotator use a unique substring from the anchor text to find a new position for the annotation in the document. While this will be robust when the anchor ....

....and retrieving annotations) at great length. They include a brief definition of their PRDMitem annotation structure, which bears some resemblance to the CAF annotation element, but the system is focused on annotating text documents and does not address a wider class of annotation activities [22]. 9.3 Research Systems A wide variety of research systems have been developed over the past decade to experiment with various annotation features, and some have claimed to establish standards for annotations on the web. The W3C Annotea system, for example, is an RDF based annotation system. It ....

Annotations are comments added by peoples to communicate with others about a subject on a document supposed being read by annotators. 4] 5] 6] [8], 9] Annotations are also means that carry knowledge on the document being read and are a broadly useful mechanism that can support a number of useful document management applications, e.g. third party commentary, design rationale, information filtering, and semantic labeling of document content ....

People in a shared workspace can be notified immediately or the next time they enter it. The Annotator [17] and ComMentor [18] annotation systems allow people to search the set of annotations made on a document. This provides information about new annotations, but requires additional work by the user. Informational methods update users on what has happened since their last visits, but rely on use of the system to ....

Supporting digital library users in organising and annotating material found through querying of digital libraries is a problem domain that has been addressed by many digital library researchers [20] 25] [34]. This paper addresses the problem faced by digital library users when having to use digital information for specific tasks. 1.1 The WWW and Digital Libraries The WWW is emerging as an infrastructure implementing part of the universally available body of information envisioned by the early ....

....However, no use has generally been made of this facility with respect to providing types. Thus, to our knowledge, no open hypermedia system has implemented thorough support for link types, including hierarchical type systems and editors and browsers for link types. The ComMentor architecture [34] provides means for annotating Web pages. This facility may be used in a similar way as attribute value pairs to simulate types of links. 2.4 Types in Programming Languages Since the 50 s, types have been an integral part of many programming languages [35] In programming languages, a type is a ....
