Strategies for Expressing Concise, Helpful Answers 总被引:2,自引:0,他引:2
David N. Chin 《Artificial Intelligence Review》2000,14(4-5):333-350
An intelligent help system needs to take into account the user's knowledgewhen formulating answers. This allows the system to provide more conciseanswers, because it can avoid telling users things that they already know.Since these concise answers concentrate exclusively on pertinent newinformation, they are also easier to understand. Information about theuser's knowledge also allows the system to take advantage of the user'sprior knowledge in formulating explanations. The system can provide betteranswers by referring to the user's prior knowledge in the explanation(e.g., through use of similes). This process of refining answers is calledanswer expression.The process of answer expression has been implemented in the UCExpresscomponent of UC (UNIX Consultant), a natural language system that helps theuser solve problems in using the UNIX operating system. UCExpress separatesanswer expression into two phases: pruning and formatting.In the pruning phase, subconcepts of the answer are pruned by being markedas already known by the user (and hence do not need to be generated), ormarked as candidates for generating anaphora or ellipsis (since they arepart of the conversational context). In the formatting phase, UCExpressuses information about the user's prior domain knowledge to select amongspecialized expository formats,such as similes and examples, for expressing information to the user. Theseformats allow UCExpress to present different types of information to theuser in a clear, concise manner. The result of UCExpress' answer expressionprocess is an internal form that a tactical level generator can easily useto produce good English. 相似文献

为了提供更具可信度的搜索结果以及更高的用户满意度,一个可行的方案是在现行的搜索;引擎的架构上引入用户评价系统。经过改良后的搜索引擎在对搜索结果进行排序时应该不仅仅考虑网址指向因素。同时应该考虑用户评价因素。采用的用户评价系统应该对所有使用者开放,界面应该尽量简单,同时应该对不同的评价给予不同的权重。 相似文献

This paper presents an approach to automated building grouping and generalization. Three principles of Gestalt theories, i.e.
proximity, similarity, and common directions, are employed as guidelines, and six parameters, i.e. minimum distance, area
of visible scope, area ratio, edge number ratio, smallest minimum bounding rectangle (SMBR), directional Voronoi diagram (DVD),
are selected to describe spatial patterns, distributions and relations of buildings. Based on these principles and parameters,
an approach to building grouping and generalization is developed. First, buildings are triangulated based on Delaunay triangulation
rules, by which topological adjacency relations between buildings are obtained and the six parameters are calculated and recorded.
Every two topologically adjacent buildings form a potential group. Three criteria from previous experience and Gestalt principles
are employed to tell whether a 2-building group is ‘strong,’ ‘average’ or ‘weak.’ The ‘weak’ groups are deleted from the group
array. Secondly, the retained groups with common buildings are organized to form intermediate groups according to their relations.
After this step, the intermediate groups with common buildings are aggregated or separated and the final groups are formed.
Finally, appropriate operators/algorithms are selected for each group and the generalized buildings are achieved. This approach
is fully automatic. As our experiments show, it can be used primarily in the generalization of buildings arranged in blocks.

Most elders suffer from different levels of memory decline, from severe to mild. For supporting the independent living and providing the smart services to the elders, assistive reminder technology has been proposed as a promising approach to address these challenges, which are able to provide necessary help to elders in appropriate time. This paper investigates the smart assistant technique. We propose a user behavior model to describe activities of the forgetful elderly. Based on this model, we develop a smart assistive reminder, which provides reminders according to elders' practical needs, and avoids unnecessary notifications that will disrupt the elders' life. The preliminary experiments evaluate the effectiveness of our approach. 相似文献

Adaptive Hypermedia 总被引:9,自引:2,他引:7
Adaptive hypermedia is a relatively new direction of research on the crossroads of hypermedia and user modeling. Adaptive hypermedia systems build a model of the goals, preferences and knowledge of each individual user, and use this model throughout the interaction with the user, in order to adapt to the needs of that user. The goal of this paper is to present the state of the art in adaptive hypermedia at the eve of the year 2000, and to highlight some prospects for the future. This paper attempts to serve both the newcomers and the experts in the area of adaptive hypermedia by building on an earlier comprehensive review (Brusilovsky, 1996; Brusilovsky, 1998). 相似文献
