檢索詞彙來源探析

本文旨在探討檢索詞彙之來源與接續詞彙的演變情形。研究共計有效檢索者37人進行40次檢索，產生411個檢索詞彙。研究發現，檢索者最常使用的詞彙來源是檢索互動來源，其次是書面問題陳述來源，而最不常被使用的檢索詞彙來源則是瀏覽檢出文獻來源。研究結果顯示，各詞彙來源與接續詞彙來源間之關係並非各自獨立，而是相互影響的，尤其是前後兩詞彙傾向選用同一來源；若前後為不同詞彙來源時，則檢索互動來源為接續詞彙之主要來源。本研究冀望藉由研究實際檢索過程，瞭解檢索詞彙來源與接續詞彙的演變情形，以增進資訊檢索系統對檢索者認知決策過程的瞭解，進而作為設計檢索中介系統之參考。

This paper is a study of the sources of search terms. 411 terms emerged as a result of 40 searches from 37 samples. The user interaction source provided the largest proportion of search terms （51.8%）, followed by question statement source. Only 4.2% of search terms are the result of browsing retrieved items. An analysis of sequences of selected search terms indicates attended to come from the preceding source. When we consider different source to different source relationships in their own, user interaction is high likely the source of search terms.
