摘要

圖書館重視資訊的蒐集、傳布與利用,並以解決讀者資訊問題為主要工作任務,而身為資訊服務提供者之圖書館館員面對工作上之資訊問題時,其如何尋求資訊來解決問題是本研究之探討動機。依據16 位大學圖書館館員之訪談結果,發現大學圖書館館員之資訊需求種類與其工作任務密切相關。基於圖書資訊學課程之專業訓練,館員並無明顯之資訊尋求障礙。館員會透過多種管道取得資訊,但偏好自人際網絡尋求協助及使用網路資源蒐集資訊,而不同的工作任務及資訊尋求之緊急程度會影響館員之資訊管道使用。

Abstract

The main missions of libraries are to gather and disseminate information and to assist users in solving information problems. To investigate the methods of seeking information used by librarians in dealing with their daily tasks in workplace, this study uses in-depth interviews to investigate the information needs and information-seeking behavior of 16 academic librarians in universities. The results show that the categories of the librarians’ information needs are highly associated with the requirements of their tasks. University librarians have no difficulty in finding information because of their Library and Information Science majors. Although librarians use numerous information sources to obtain information, they particularly rely on interpersonal network and the Internet. The type of tasks and the extent of emergency of an information need also affect information sources used by librarians.

摘要

面對網路資源檢索結果往往過多的問題,如何將當中最相關的資訊優先排序在最前面,讓使用者優先看到,以節省其瀏覽所有檢索結果的時間,是目前系統開發者選擇相關排序(Relevance ranking)作為檢索結果排序的原因。目前大部分的資訊檢索系統係以相似性而非相關性作為檢索結果排序基礎,但使用者係判斷檢索結果相關與否之唯一裁判者,為此,相關排序的發展也開始將使用者的相關判斷及資訊使用行為作為改善相關排序效能之努力方向,希望能針對使用者的不同需求提供更個人化的資訊服務。

Title Development and Issues Concerning the Relevance Rankings for Information Retrieval
Author Yu-wei Chang
Author's title Department of Library and Information Science, NTU
Abstract

The retrieval results of a web search are usually very large. Therefore, the information retrieval system usually uses the relevance ranking to ranking retrieval results, providing users a saving-time way to look through the searching results and obtain the most relevant documents. Currently, most information retrieval systems use similarity instead of relevance to rank the searching results. However, the end-user is the one to determine the relevance of retrieval results, so many researchers consider the user’s relevance requirement and information behavior are the way to improve the effectives of relevance ranking. The objective of relevance ranking is to provide personalized information service for users.
