基于FLaAT的模糊用户偏爱浏览模式的增量挖掘

挖掘用户偏爱的浏览模式就是从Web日志中发现多数用户偏爱的浏览路径.网页上的浏览时间被转换成一个模糊语言变量来体现网页上浏览时间的特征,最后从建立的包含所有用户浏览信息的FLaAT(Frequent Link and Access Tree)中挖掘增量式带有模糊语言变量的用户偏爱浏览模式.

Multivariate study of moose browsing in relation to phenol pattern in pine needles

Extracts of needles from Scots pine,Pinus sylvestris L., grown on fertile (A) or poor (B) soil, and from lodgepole pine,P. contorta Doug. (C), have been analyzed with HPLC and UV detection. By application of multivariate analysis, the phenol pattern was shown to vary between species and between habitats. Within groups A and B, moose food choice was highly correlated to phenol pattern. Concentrations of most of the analyzed compounds were internally correlated. Information related to pine growth rate could also be extracted from the phenolic pattern for A, B, and C. Moose food choice was not correlated to pine growth rate.

Device-aware desktop web page transformation for rendering on handhelds

This paper illustrates a new approach to automatic re-authoring of web pages for rendering on small-screen devices. The approach is based on automatic detection of the device type and screen size from the HTTP request header to render a desktop web page or a transformed one for display on small screen devices, for example, PDAs. Known algorithms (transforms) are employed to reduce the size of page elements, to hide parts of the text, and to transform tables into text while preserving the structural format of the web page. The system comprises a preprocessor that works offline and a just-in-time handler that responds to HTTP requests. The preprocessor employs Cascading Style Sheets (CSS) to set default attributes for the page and prepares it for the handler. The latter is responsible for downsizing graphical elements in the page, converting tables to text, and inserting visibility attributes and JavaScript code to allow the user of the client device to interact with the page and cause parts of the text to disappear or reappear. A system was developed that implements the approach and was used it to collect performance results and conduct usability testing. The importance of the approach lies in its ability to display hidden parts of the web page without having to revisit the server, thus reducing user wait times considerably, saving battery power, and cutting down on wireless network traffic.     

Video parsing and browsing using compressed data

Parsing video content is an important first step in the video indexing process. This paper presents algorithms to automate the video parsing task, including partitioning a source video into clips and classifying those clips according to camera operations, using compressed video data. We have developed two algorithms and a hybrid approach to partitioning video data compressed according to the JPEG and MPEG standards. The algorithms utilize both the video content encoded in DCT (Discrete Cosine Transform) coefficients and the motion vectors between frames. The hybrid approach integrates the two algorithms and incorporates multi-pass strategies and motion analyses to improve both accuracy and processing speed. Also, we present content-based video browsing tools which utilize the information, particularly about the shot boundaries and key frames, obtained from parsing.

A Schematic Entry Drawing Capability in a Linearised Hypermedia System

This paper describes a linearised hypermedia system, called the Book Emulator, that generally supports the capture of diagrammatic specifications such as SSADM and electronic circuit diagrams, and the capture of mathematical notations such as Z. Since the Book Emulator can be closely coupled to applications, it can be used as the user-interface to that application. Doing so automatically provides a conferencing mechanism on behalf of applications and a mechanism for recording the engineering analyses performed by the application. It is argued that this is the next and higher step in the trend to separate the user-interface from the application. The schematic entry mechanism has been designed to minimise the user's physical and mental effort so that the user may concentrate on drawing strategy. This is achieved by minimising the number of selections (steps) required to reach an atomic goal, and by refraining from hiding functionality in menus. The paper concludes with an indication of how the generalised schematic capture mechanism might be exploited in systems that allow end- users to organise and specify their information requirements.
