New Search Patent Applications: June 5, 2006 - Taking Care of Web Decay, Dead Links, and Parked Domains

by , Comments

Yahoo provides an XML based bid management tool, and a way to maintain a persistent link to dynamic information between a browser and specific web pages. Microsoft marries email and search to provide a way store and track queries, and also introduces a method of calculating similarity between pages without the computational overhead of a Latent Semantic Indexing methodology. IBM aims to improve text search by preprocessing and maintaining relationship data between documents, delivers a means of spellchecking URLs, describes a process for personalizing web pages which include personalized search results, and introduces a method to rank pages while accounting for dead links and the decay of content on web pages.

ISEN, L.L.C., has developed an internet search environment number for internet databases to expand search to deep content, rarely indexed by web-based search engines. Zoom Information, Inc., has developed a method of collecting data about people from the web, to present in a structured database to make searching for information about people easier. Bing Swen, from Peking University, has created an improved process for search result clustering. Two Amazon employees have had a patent application published which may correct misspellings in queries in order to return results to searchers.

IBM

This first document may be the star of this batch of search filings, and if you decide to try to read through any of these, this may be a good choice. Two of the inventors listed in this patent application are now at Yahoo. Ironically, one of their main examples of the problem of web decay involves the Yahoo Directory.

There are a number of nice ideas here, which touch on why dead links and web decay aren't good for search engines, how most dead links can be identified regardless of whether a server returns a 404 error message or not, and how some exceptions such as parked domains (including expired domains purchased to benefit a site by using promotional efforts of previous owners) are now being looked at carefully by search engineers.

Methods and apparatus for assessing web page decay
Inventors: Andrei Zary Broder, Ziv Bar-Yossef, Shanmagasundaram Ravikumar, Andrew Tomkins
US Patent Application 20060112089
Published May 25, 2006
Filed: November 22, 2004

Abstract

Systems and methods are herein disclosed for assessing the staleness of a web page. In particular, in one method of the present invention, the staleness of a web page is assessed by examining internal date references within the web page. In another method of the present invention, the staleness of a web page is assessed by examining the meta-data associated with the web page. In a further method of the present invention, the staleness of a hyperlinked web page is determined by examining the link status of the hyperlinks. If the web page has a relatively large number of dead links, it is assessed as being a stale web page. In a still further method of the present invention, the link status of web pages in the neighborhood of the web page being assessed is likewise examined.

Inventors: Benyu Zhang, Hua-Jun Zeng, Wei-Ying Ma, Zheng Chen, Ning Liu, and Jun Yan
US Patent Application 20060112068
Published May 25, 2006
Filed: November 23, 2004

Abstract

A method and system for determining similarity between items is provided. To calculate similarity scores for pairs of items, the similarity system initializes a similarity score for each pair of objects and each pair of features. The similarity system then iteratively calculates the similarity scores for each pair of objects based on the similar scores of the pairs of features calculated during a previous iteration and calculates the similarity scores for each pair of features based on the similarity scores of the pairs of objects calculated during a previous iteration. The similarity system implements an algorithm that is based on a recursive definition of the similarities between objects and between features. The similarity system continues the iterations of recalculating the similarity scores until the similarity scores converge on a solution.

Method for maintaining people and organization information
Inventors: Jonathan Stern, Jeremy W. Rothman-Shore, Kosmas Karadimitriou, and Michel Decary
US Patent 7,054,886
Granted May 30, 2006
Filed: July 27, 2001

Abstract

A database is formed and maintained by computer-automated means extracting information from a global computer network. The database contains information about people and organizations. The present invention method provides continual updates to the information stored in the database by the people named in the database and by the automated means. Integrity of the automatically extracted information is maintained. A link from the invention database to a third party data system provides updates in the information in the database to be communicated to the third party data system for updating and maintaining data of the third party data system. The database may serve as an email communication clearinghouse where senders do not need to know the email address of a person named in the database but rather leaves messages through that person's record in the database. Targeted advertising to a named person is provided during his accessing the database. The targeted advertising is based on information about the named person as stored in the database. The database may be queried by any combination of person name, job title, organization name and field of business of the organization. The invention method provides clipping service which monitors changes in the information stored in the database and notifies interested parties of detected changes.

Method for search result clustering
Inventors: Bing Swen
US Patent Application 20060117002
Published June 1, 2006
Filed: November 1, 2005

Abstract

Methods and systems are presented to predetermine and record the classes of each indexed document with respect to each of its index keywords, and to provide high quality and relevant classification of the document when it is searched with said keyword. Document classes, recorded in advance, are used as the clustering information of each document in the search results to realize efficient, large-scale and high quality search result clustering. One embodiment provides a method for search result clustering, which includes recording the classes of each indexed document when the document is searched with each of its index keywords. This method further includes grouping the search results according to the classes of each result document with respect to the keyword or keywords contained in the search query. By prerecording the classes of each document with respect to each index keyword, the classes of each document in the search results in response to a search query can be directly determined via the keywords included in the search query. Each result document is put into each of its classes associated with each of the search keywords, and the union of all the classes of the result documents is used to construct the final document clusters for the search results. The clusters are ranked according to the ranks of documents included in each cluster and the weights of the clustered documents in the corresponding cluster. The clustered search results are presented to the user in such a way that clusters with higher ranks, and documents with higher ranks in each cluster are preferentially presented. Each cluster can be displayed and navigated in an independent framed subarea of the output window.


The inventors listed in the following patent application are Amazon.com employees, though the document hasn't been assigned to Amazon, and examples within the document include searches for books within an online bookstore. When a search query is misspelled, rather than not returning results to a searcher, the process here may try to find a suitable replacement. So, for instance, a search for "The De Vinci Code " shows results that begin with "The Da Vinci Code." at Amazon.com


Search query processing to identify related search terms and to correct misspellings of search terms
Inventors: Ruben Ernesto Ortega and Dwayne Edward Bowman
US Patent Application 20060117003
Published June 1, 2006
Filed: January 6, 2006

Abstract

A search engine process predicts the correct spellings of search terms within multiple-term search queries. In one embodiment, when a user submits a multiple-term search query that includes a non-matching term and at least one matching term, a table is accessed to look up a set of terms that are "related" to the matching term or terms. A spelling comparison function is then used to determine whether any of these related terms is sufficiently similar in spelling to the non-matching term to be deemed a candidate correctly-spelled replacement. A candidate replacement term may automatically be substituted for the non-matching term, or may be suggested to the user as a replacement. The invention also includes a process for identifying terms that are related to each other based on the relatively high frequencies with which they co-occur in search queries of users, database records, and/or specific database fields.

My usual reminder about patents: Some of the processes and technology described in patents are created in house, and some are developed with the assistance of contractors and partners. A percentage are never developed in a tangible manner, but may serve as a way to attempt to exclude others from using the technology, or even to possibly mislead competitors into exploring an area that they might not have an interest in (sometimes skepticism is good.)

There are times when a Google or Yahoo acquires a company to gain access to the intellectual property of that company, or the intellectual prowess and expertise of that company's employees. And sometimes patents are just purchased.
