SoftwareFrom: Mohammed Zaki Date: Thu, 26 Jul 2001 12:09:58 -0400 Subject: LOGML: Log Markup Language Schema and DTD Available LOGML (Log Markup Language) Draft Specification and Schema ----------------------------------------------------------- We are glad to announce the draft specification of LOGML (Log Markup Language) and Schema at: http://www.cs.rpi.edu/~puninj/LOGML/ Log Markup Language (LOGML) is an XML 1.0 application designed to describe log reports of web servers. Web-data mining is one of the current hot topics in computer science. Mining data that has been collected from web server logfiles, is not only useful for studying customer choices, but also helps in organizing web pages. This is accomplished by knowing which web pages are most frequently accessed by the web surfers. The structure of a web site is represented as a web graph using XGMML (eXtensible Graph Markup and Modeling Language; see below). In mining the data from the log statistics, we use the web graph in annotating the log information. Further we give summary reports, comprising of information such as client sites, types of browsers and the usage time statistics. We also gather the client activity in a web site as a subgraph of the web site graph. This subgraph can be used to get better understanding of general user activity in the web site. In LOGML, we create a new XML vocabulary to structurally express the contents of the logfile information. We provide with a LOGML dtd and LOGML Schema (based on XML Schema W3C Recommendation 2 May 2001). Application of LOGML for Web Usage Mining is described in detail in the following paper (to appear in WEBKDD01): http://www.cs.rpi.edu/~zaki/papers.html#WEBKDD01 XGMML (eXtensible Graph Markup and Modeling Language) Schema Update ------------------------------------------------------------------- We are also glad to announce the update of XGMML schema, based on XML Schema W3C recommendation, at: http://www.cs.rpi.edu/~puninj/XGMML/ XGMML (eXtensible Graph Markup and Modeling Language) is an XML application based on GML which is used for graph description. XGMML uses tags to describe nodes and edges of a graph. The purpose of XGMML is to make possible the exchange of graphs between differents authoring and browsing tools for graphs. The conversion of graphs written in GML to XGMML is trivial. Using XSL with XGMML allows the translation of graphs to different formats. XGMML was created to be used for the WWWPAL System that visualizes web sites as a graph. Web Robots can navigate through a web site and save the graph information as an XGMML file. XGMML, as any other XML application, can be mixed with other markup languages to describe additional graph, node and/or edge information. Questions and comments are welcome.
