A New Beta From Amazon.Com: Search and Browse Restaurant Menus
Similar to Google Catalogs, this beta provides users with the ability to search
(using optical character recognition) and browse a selection of restaurant menus
in 6 cities, with more to come. The current cities available are: Washington
D.C., Chicago, New York, Los Angeles, San Francisco, and Seattle. Another useful
and potentially "tasty" use of search technology. Bon Appetit!

Google2002编程比赛结果揭晓，纽约的Daniel Egnor凭“Geographic Search”或得1万美元的头奖。
+ Daniel's project adds the ability to search for web pages within a particular
geographic locale to traditional keyword searching. To accomplish this, Daniel
converted street addresses found within a large corpus of documents to latitude-longitude-based
coordinates using the freely available TIGER and FIPS data sources, and built
a two-dimensional index of these coordinates. Daniel's system provides an interface
that allows the user to augment a keyword search with the ability to restrict
matches to within a certain radius of a specified address (useful for queries
that are difficult to answer using just keyword searching, such as "find me
all bookstores near my house"). We selected Daniel's project because it combined
an interesting and useful idea with a clean and robust implementation. Honorable
mentions
+ Zhenlei Cai, for his project, Discovery and Grouping of Semantic Concepts
from Web Pages with Applications. This effort processed a corpus of documents
and found words and phrases that tend to co-occur within the same document,
producing a list of pairs of terms that seem to be closely related (such as
"federal law" and "supreme court", or "Bay Area" and "San Francisco").
+ Laird Breyer, for his project, Markovian Page Ranking Distributions: Some
Theory and Simulations. This project examined various properties of the Markovian
process behind Google's PageRank algorithm, and suggested some modifications
to take into account the "age" of each link to reduce Pagerank's tendency to
bias against newly-created pages.
+ Thomas Phelps and Robert Wilensky, for their project, Robust Hyperlinks. Traditional
hyperlinks are very brittle, in that they are useless if the page later moves
to a different URL. This project improves upon traditional hyperlinks by creating
a signature of the target page, selecting a set of very rare words that uniquely
identify the page, and relying on a search engine query for those rare words
to find the page in the future. For example, the Google programming contest
can be found using this link.
+ Aaron Peapell, for his project, Genetic Search Algorithm. This project used
a genetic search algorithm to bias a Pagerank-like algorithm in a query-specific
manner, by giving higher weight to links from pages containing all of the query
terms.
+ Dan Blandford and Guy Blelloch, for their project, Index Compression Through
Document Reordering. This project aims to reduce the space requirements of an
inverted index by clustering together documents that are similar before assigning
numerical identifiers to the documents (leading to locality in the document
identifier sequences within the inverted posting lists for the words in the
index, thereby making the sequences more compressible with various types of
encoding techniques).

"Automatic user interest profile generation from structured document access
information" #6,385,619
Asignee: IBM
Issue Date: 5/7/02
From the abstract, "A system generates user interest profiles by monitoring
and analyzing a user's access to a variety of hierarchical levels within a set
of structured documents, e.g., documents available at a web site. Each information
document has parts associated with it and the documents are classified into
categories using a known taxonomy. The user interest profiles are automatically
generated based on the type of content viewed by the user."
