| Brief Description | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
This course will cover modeling and algorithmic aspects of web search engines. Topics (subject to time permission) include tf-idf scoring, page ranks, inverted indexes, tries, suffix trees/arrays, q-grams, error-tolerant keyword search, and deep webs. On completion, students are expected to have acquired solid understanding on fundamental text retrieval and link analysis. |

No existing textbook contains all the materials in this course. The following is a good (and fun) reference book that covers about 30% of the contents: Michael W. Berry, Murray Browne. Understand Search Engines: Mathematical Modeling and Text Retrieval. 2nd edition, SIAM Book Series: Software, Environments, and Tools. ISBN: 0-89871-581-4. In addition, the following papers are nice reading related to this course: [LM05] Langville, A., and Meyer, C. A Survey of Eigenvector Methods of Web Information Retrieval. SIAM Review, 47(1): 135-161, 2005. [SZTJ12] Sheng, C., Zhang, N., Tao, Y., Jin, X. Optimal Algorithms for Crawling a Hidden Database in the Web.
