Abstraction of search engine architecture User Ranker Indexer Doc Analyzer Index results Crawler Doc Representation Query Rep (Query) Evaluation Feedback Information Retrieval2 Indexed corpus Ranking procedure

Search interface Evolution of Google’s result interface – evolution/ evolution/ 6501: Information Retrieval3

Google’s 6501: Information Retrieval4

Bing’s 6501: Information Retrieval5

Yahoo’s 6501: Information Retrieval6

What are there A list of links to the search result page – Text summarization of the retrieved document Title + text snippet Search suggestions – Related search – Spelling correction – Query auto-completion Vertical search – Image, shopping, news Knowledge graph – As a result of NLP techniques It has been there since the search engine was born Simple Q&A 6501: Information Retrieval7

Query auto-completion 6501: Information Retrieval8

Considerations in result display Relevance – Order the results by relevance Diversity – Maximize the topical coverage of the displayed results Navigation – Help users easily explore the related search space Query suggestion Search by example 6501: Information Retrieval19

In Human-Computer Interaction – Eye/Mouse tracking study of interaction between users and search result page – Psychological study of user behaviors Facet categories, text summaries, colors, positions In Information Retrieval – Less attention has been put in this aspect in history – Attracting more and more research focus now Research progress 6501: Information Retrieval20

Search result display in mobile device Unique characteristics of mobile device – Small screen size, limited bandwidth, input, data- access and computation power – Multi-touch screen – Rich search context – Opportunities? 6501: Information Retrieval21
