Interactive Document Retrieval using Faceted Terminological Feedback
نویسندگان
چکیده
We present a new interactive paradigm for iterative information retrieval based on the automatic construction of a faceted representation for a document subset. Facets are chosen heuristically based on lexical dispersion, a measure of the number of different terms with which a word co-occurs within noun phrases appearing in the document set. The phrases in which these terms occur serve to provide a set of attributes, specializations, related concepts, etc., for the so-identified “facet” terms. The resulting representation serves the dual purpose of providing a concise, structured summary of the contents of a result set as well as presenting a set of terms for engaging in interactive query reformulation.

Document Image Retrieval Based on Keyword Spotting Using Relevance Feedback
Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...
متن کاملA Collaborative Document Ranking Model for a Multi-faceted Search
This paper presents a novel collaborative document ranking model which aims at solving a complex information retrieval task involving a multi-faceted information need. For this purpose, we consider a group of users, viewed as experts, who collaborate by addressing the different query facets. We propose a two-step algorithm based on a relevance feedback process which first performs a document sc...
متن کاملComparative Analysis for SVM-Based Interactive Document Retrieval
Support Vector Machines (SVMs) were applied to interactive document retrieval that uses active learning. In such a retrieval system, the degree of relevance is evaluated by using a signed distance from the optimal hyperplane. It is not clear, however, how the signed distance in SVMs has characteristics of vector space model. We therefore formulated the degree of relevance by using the signed di...
متن کاملA Kernel for Interactive Document Retrieval Based on Support Vector Machines
This paper describes an application of support vector machines (SVMs) to interactive document retrieval using active learning. We show that an SVM-based retrieval has an association with conventional Rocchio-based relevance feedback by a comparative analysis. We propose a cosine kernel, which denotes cosine similarity, suitable for an SVM-based interactive document retrieval based on the analys...
متن کاملPersonalization of Information Retrieval in Different Types of Tasks
[email protected]; [email protected]; [email protected]; [email protected] ABSTRACT In this paper, we propose to personalize search result content through modeling multiple user behavioral measures in different ways as evidence for implicit relevance feedback for different types of search tasks. The point of this personalization is to predict potentially useful documents based on the t...
