Information Retrieval: Searching in the 21st Century (Hardcover)

Information retrieval (IR) can be defined as the process of representing, managing, searching, retrieving, and presenting information. Good IR involves understanding information needs and interests, developing an effective search technique, system, presentation, distribution and delivery. The increased use of the Web and wider availability of information in this environment led to the development of Web search engines. This change has brought fresh challenges to a wider variety of users’ needs, tasks, and types of information.

Today, search engines are seen in enterprises, on laptops, in individual websites, in library catalogues, and elsewhere. Information Retrieval: Searching in the 21^st Century focuses on core concepts, and current trends in the field.

This book focuses on:

• Information Retrieval Models
• User-centred Evaluation of Information Retrieval Systems
• Multimedia Resource Discovery
• Image Users’ Needs and Searching Behaviour
• Web Information Retrieval
• Mobile Search
• Context and Information Retrieval
• Text Categorisation and Genre in Information Retrieval
• Semantic Search
• The Role of Natural Language Processing in Information Retrieval: Search for Meaning and Structure
• Cross-language Information Retrieval
• Performance Issues in Parallel Computing for Information Retrieval

This book is an invaluable reference for graduate students on IR courses or courses in related disciplines (e.g. computer science, information science, human-computer interaction, and knowledge management), academic and industrial researchers, and industrial personnel tracking information search technology developments to understand the business implications. Intermediate-advanced level undergraduate students on IR or related courses will also find this text insightful. Chapters are supplemented with exercises to stimulate further thinking.

這本書是關於資訊檢索的前沿議題和未來發展方向的重要參考資料。資訊檢索（IR）可以定義為代表、管理、搜索、檢索和呈現資訊的過程。良好的資訊檢索涉及理解資訊需求和興趣，開發有效的搜索技術、系統、呈現、分發和交付。網絡的廣泛使用和在這個環境中資訊的更廣泛可用性導致了網絡搜索引擎的發展。這一變化為更廣泛的用戶需求、任務和資訊類型帶來了新的挑戰。

如今，搜索引擎在企業、筆記型電腦、個別網站、圖書館目錄等地方都得到了應用。《資訊檢索：21世紀的搜索》專注於核心概念和當前領域趨勢。

本書重點介紹以下內容：
- 資訊檢索模型
- 以用戶為中心的資訊檢索系統評估
- 多媒體資源發現
- 圖像使用者需求和搜索行為
- 網絡資訊檢索
- 移動搜索
- 上下文和資訊檢索
- 文本分類和類型在資訊檢索中的應用
- 語義搜索
- 自然語言處理在資訊檢索中的作用：尋找意義和結構
- 跨語言資訊檢索
- 資訊檢索中的並行計算性能問題

這本書對於修讀資訊檢索課程或相關學科（如計算機科學、資訊科學、人機交互和知識管理）的研究生、學術和工業研究人員以及追踪資訊搜索技術發展以了解業務影響的工業人員來說是一本寶貴的參考資料。中高級本科生修讀資訊檢索或相關課程的學生也會發現這本書具有洞察力。每章還附有練習題以激發進一步思考。
