Streszczenie:

Relevance is an essential concept in information retrieval (IR) and relevance estimation is a fundamental IR task. It involves not only document relevance estimation, but also estimation of user's information need. Relevance-based language model aims to estimate a relevance model (i.e., a relevant query term distribution) from relevance feedback documents. The true relevance model should be generated from truly relevant documents. The ideal estimation of the true relevance model is expected to be not only effective in terms of mean retrieval performance (e.g., Mean Average Precision) over all

Streszczenie:

A new relevance feedback technique called Weight Propagation has been developed which provides greater retrieval effectiveness than previously described techniques. Documents judged relevant by the user propagate positive Weights to documents close by in vector similarity space, while documents judged not relevant propagate Negative Weights to such neighbouring documents. Variants of Weight Propagation are also described, namely WPI and WPR (inspired by Ide and Rocchio respectively), and WPY which is the main focus of this thesis, where only the maximum weight propagated to each document is co

Relevance Feedback is a technique that helps an Information Retrieval system modify a query in response to relevance judgements provided by the user about individual results dis played after an initial retrieval. This thesis begins by proposing an evaluation framework for measuring the effectiveness of feedback algorithms. The simulation-based method in volves a brute force exploration of the outcome of every possible user action. Starting from an initial state, each available alternative is represented as a traversal along one branch of a user decision tree. The use of the framework is illust

In content-based image retrieval (CBIR) systems, there are two general types of search: target search and category search. Unlike queries in traditional database systems, users in most cases cannot specify an ideal query to retrieve the desired results for either target search or category search in multimedia database systems, and have to rely on iterative feedback to refine their query. Efficient evaluation of such iterative queries can be a challenge, especially when the multimedia database contains a large number of entries, and the search needs many iterations, and when the underlying dist

The increasing reliance of people on computers for daily tasks has resulted in a vast number of digital documents. Search engines were once luxury tools for quickly scanning a set of documents but are now quickly becoming the only practical way to navigate through this sea of information. Traditionally, search engine results are based upon a mathematical formula of document relevance to a search phrase. Often, however, what a user deems to be relevant and what a search engine computes as relevant are not the same. User feedback regarding the utility of a search result can be collected in orde

The aim of this thesis work is to improve the performance of an already existing information retrieval system that uses relevance feedback for performing query expansion. It is a constant goal to improve this system because the docu- ments that are retrieved are a base for various data analysis tasks. It is therefore important that the precision and re- call are high. A user can choose to give relevance feedback when executing a query, meaning the user can mark docu- ments in the search result as relevant or irrelevant and redo the search based on this feedback.

Hundreds of millions of users each day search the web and other repositories to meet their information needs. However, queries can fail to find documents due to a mismatch in terminology. Query expansion seeks to address this problem by automatically adding terms from highly ranked documents to the query. While query expansion has been shown to be effective at improving query performance, the gain in effectiveness comes at a cost: expansion is slow and resource-intensive. Current techniques for query expansion use fixed values for key parameters, determined by tuning on test collections

碩士<br>國立臺灣大學<br>資訊工程學研究所<br>93<br>With the exponential growth of multi-media data, finding images in a large database has become more difficult. Region-based image retrieval (RBIR) is used for solving this problem in this thesis. There are some differences between RBIR and traditional content-based image retrieval (CBIR) systems. CBIR is focused on the similarity of global images and RBIR is focused on the similarity of the local image regions. We apply the watershed segmentation to segment each image into some regions. To classify these regions, the fuzzy k-means clustering algorithm is time-

碩士<br>義守大學<br>資訊工程學系<br>92<br>In the recent years, digital multimedia has been applied for various applications. Effective management becomes an important role for retrieval from database. This thesis aims at building a content-based retrieving system to retrieve desired images from database. There are two main contributions. First, we propose an image feature database based on human’s perception. This method collects the information of center region in an image, The system is divided into a global feature database, regional feature database to the choice of the feature database whi

碩士<br>國立成功大學<br>資訊工程學系碩博士班<br>91<br>A procedure is studied for the purpose of retrieval efficiency improvement for text data to save the cost for who eager for information. In this thesis, a new relevance feedback technique is developed and applied for information retrieval. We focus on automatically adapting model parameters to improve the retrieval performance. Traditionally, the “query expansion” and “query term reweighting” are viewed as two popular of relevance feedback approaches. In this study, the retrieval framework is based on the mixture N-gram model. To improve the retrieval perfo

碩士<br>國立臺灣大學<br>資訊工程學研究所<br>90<br>The aim of this thesis is to build a content-based image retrieval system. It is to retrieve the desired images for a user from a large image database, based on the image contents. In the thesis, a system is implemented and two contributions are made for content-based image retrieval. One is the design of a new feature based on the results of multi-scale watershed image segmentation, which measures the distribution of colors and sizes of segmented regions. The other one is the derivation of a new method for relevance feedback based on Bayesian formulation. In

碩士<br>國立暨南國際大學<br>資訊管理學系<br>95<br>Due to the popularity of Internet and the growing demand of image access, the volume of image databases is exploding. Hence, we need a more efficient and effective image searching technology. Relevance feedback (RF) is an interaction process between the user and the system such that the user’s information need is satisfied by the retrievals from the system. Traditional RF techniques use the same system parameter values for all types of query images. It is questionable that the best performance can be obtained through such setting. Hence, we propose self-adapti
