Similarity-based retrieval of stored objects is one of the main building blocks of a case-based reasoning approach (CBR). Over the last three decades several sophisticated retrieval methods have been developed which are more suitable for many real-world scenarios than the traditional database search. However, the CBR approach and in particular the published retrieval methods do not support suff...

many important and useful applications for software agents require multiple agents on a network that communicate with each other. we often use the word “agent” to describe people who have a helping or assistive relationship to us –– travel agents, secretaries, butlers. the job of such an agent is to act autonomously to satisfy goals that we may have, give us a greater sense of productivity and ...

Navigational Blocks is a tangible user interface that facilitates retrieval of historical stories in a tourist spot. Orientations, movements, and relative positions of physical Blocks support visitor navigation and exploration in a virtual gallery of information. The goal is to bridge the gap and explore the boundary between the physical environment with a virtual information space. Visitors to...

This paper investigates several techniques for spoken document retrieval, toward improvement of retrieval performance based on the conventional method i.e. TF-IDF. The first approach employs rescaled unigrams of LDA to compute a similarity score. The second technique employs query expansion by web retrieval using Yahoo!API. And the third technique is Prioritized And-operator Retrieval based on ...

Latent Semantic Analysis (LSA) is an intelligent information retrieval technique that uses mathematical algorithms for analyzing large corpora of text and revealing the underlying semantic information of documents. LSA is a highly parameterized statistical method, and its effectiveness is driven by the setting of its parameters which are adjusted based on the task to which it is applied. This p...
