臺灣博碩士論文加值系統

本研究主要目的在於探索影響中文資訊檢索系統終端使用者 "相關
判斷" 的因素,希望透過對中文資訊檢索系統的使用者行為研究, 瞭解國
人對於資訊的 "相關判斷" 之特質, 期盼研究結果能提供圖書館讀者服務
與利用教育的參考, 並可在系統的改善方面, 提供有用之意見. 本研究透
過問卷, 訪談及觀察的實施, 以在國家圖書館期刊室內使用 "中華民國期
刊論文索引系統" 之讀者為研究對象, 收集研究資料, 加以分析歸納, 找
出影響讀者 "相關判斷" 的可能因素. 文末則提出結論與建議. 研究
結果發現, 影響使用者 "相關判斷" 的因素, 可歸納為內在因素與外在因
素兩 方面. 內在因素包括資訊需求與讀者個別差異; 外在因素則包括資
料內容的特性與情境 因素. 研究結果與國外的研究結果模式趨於一致,
可能因文化背景與社會環境差異, 以及系統之不同, 故而產生模式內少數
變因略有增減的情形. 研究的主要發現如下: 1. 讀者最關心的是
檢索結果是否能符合其資訊需求. 2. 讀者對 "相關" 的概念難以掌
握, 判斷時雖強調於文獻的主題方面, 但隨著資訊 需求的轉變,
對其檢索出的文獻多以 "用途" 為考量點. 3. 不同的人口特質可能產
生不同的判斷標準, 判斷的態度可能隨其身分階段的提昇 而由消
極轉向積極. 4. 讀者進行 "相關" 判斷時有其困難, 如對問題不熟
悉, 檢出文獻無法提供充分主 題資訊, 時間壓力與限制, 及檢索
出太多筆或為0筆檢索結果等.

The main purpose of this study is to explore the factors
that affect end users'' relevance judgments when using Chinese
information retrieval system. The bebavioral pattern of local
users was analyzed in order to determine their characteristics
on information relevance judgments. It is hoped that the
findings of this study can be the reference of improving the
contents of readers'' services and user education in libraries.
Also, it is helpful to improve the design for the function of
the system. Questionnaires, interviews and observation were
employed on readers using the "Index to Chinese Periodical
Literature on CD-ROM" in the periodical room at the National
Library to evaluate possible factors that affect users''
relevance judgments. Conclusions and suggestions are given at
the end of this article. The research concludes that there are
two types of possible factors affecting end users'' relevance
judgments, namely individual and extrinsic. The former includes
specific information needs and differences among individual
users. The latter includes the natures of information and
external circumstances. The results of this research are similar
to those conducted abroad, although some variations may differ
because of cultural, social and retrieval system differences.
The major findings are: 1. What concerns users most is whether
the retrieved imformation meets their informationneeds or not.
2. Users are usually arbitrary and vague about the concept of
"relevance". It is often simply judged by the topic of documents
retrieved. But as the information requirment changes, they
become more concerned about whether the contents of retrieved
information are useful. 3. Users'' educational backgrounds
influence their criteria for relevance judgments. The higher
education, the stricter the criteria. 4. Some conditions may
hinder users'' relevance judgments. For example, they are not
certain about what information they really need, the retrieved
information is not related enough, users are under time
pressure to use the information retrieval system, and too many
results or zero hit are retrieved.
