Enterprise and Site Search Notes

August 9, 2011

Pingar (new semantic search engine)
Semantic search running on top of Solr, offering an API including autocomplete, related terms, co-occurring locations and names, document summaries. Currently integrating with SharePoint, software as a service option. Has a Chinese version, more languages to come.
Scholar Citations: Google Moves into the Domain of Web of Science and Scopus
"Author profiling, rising from the need to better disambiguate researchers and to better find and connect relevant researchers, has become an increasingly hot product area in the past 2 years" -- the article describes the Google Scholar Citations system of automating profiles and allowing scholars to edit them. It also talks about Microsoft Academic Search, arXiv, ACM, RefWorks, DBLP, INSPIRE, OpenID.net, ORCID, Publish or Perish, RePEc, ReasearcherID, VIVO, and Scopus.
Interview With Louis Rosenfeld, Author of Search Analytics
Shari Thurow interviews Lou Rosenfeld about what his Site Search Analytics book can teach people concerned with SEO and search engine marketing, such as missing content, site navigation problems, keyword phrases in context.
Diego Basch on The Need for Speed [Search Engine Usability]
It never occurred to me to describe interaction design and search results usability as "speed and contrast them to traditional information retrieval relevance judgments, but, sure, why not.
IndexFile - PHP Lucene indexing
IFile is a PHP based framework for indexing documents(PDF, DOC, HTML, etc) using Lucene. Note that the documentation is in Italian.
The CIO Vs. The Information Access Mafia -- InformationWeek
Management's goal should be not to limit access to data, but to figure out a way to facilitate access. They haven't and they won't. They want to brag about the benefits when the company comes up with something great, something really innovative, but they want deep cover to protect their rears when and if we have given the wrong level of access to the wrong people.
Don't Use Java 7, For Anything >> Lucid Imagination
July 28, 2011 -- Posted by hossman -- Java 7 GA was released today, but as noted by Uwe Schindler, there are some very frightening bugs in HotSpot Loop optimizations that are enabled by default. In the best case scenario, these bugs cause the JVM to crash. In the worst case scenario, they cause incorrect execution of loops. Bottom Line: Don't use Java 7 for anything (unless maybe you know you don't have any loops in your java code)
Giving search users what they want, not what they're asking for - FierceContentManagement
Nice overview of modern site search features such as facets, best bets, taxonomy, alternate vocabulary, and related topics
Make Your Business 10X Faster with Box's New Search (company switched to Solr)
The cloud storage service Box.net switched to Solr/Lucene and has seen significantly fast indexing and searching. They are also using Apache Tika to read a wide variety of file formats.
Locayta ESP - Website Search Engine Solutions
A new ecommerce site search engine
Lucene Faceting module added to the trunk
While Solr had faceting, the core Lucene library did not have any formal support for the powerful faceted metadata approach to search results presentation. Lucene Jira ticket 3079 contains new code to do this, at very large scale (millions).
Collaborative relevance in Enterprise Search (using search analytics)
A fresh approach to the discussion of long-term search relevance, setting up a process for responding to user behavior and using it to improve results. This article is a little case study of a Findwise installation in a Swedish power company, apparently using clickthrough tracking and log analytics.
Google+ Social = World Domination?
My article for InfoToday's NewsBreaks, with a bit about how hard it is to do a near-real-time relevant searches with privacy protection.
Sorting Out Microsoft's Mixed-Up Enterprise Search Strategy -- Redmondmag.com
There are many flavors of Search Server and FAST Search, and it's still not at all clear where Microsoft will go with them.
A digital real estate firm digs into site search data to improve navigation - Internet Retailer
Tangible example of using site search analytics to make changes in content. If we see that people are looking on the site for something like 'domain authority' we can address that. It gives us a reason to develop that information on the site," says [Mary Smucker-Priest] Site search data is unique because its shows a retailer how customers are using a site, she says. It's reliable, informative data."
Don't Build Data Castles Made of Sand (ReadWriteWeb)
Strongly for enterprise search and unified information access "Leaving the data where it resides and providing unified access to it not only helps make the most of existing IT investments, it provides a full view of the information that matters most to you, which helps you make better decisions."
Designing Faceted Search: Getting the basics right (part 2) Information Interaction
Another great explanation of facet issues, the best so far. Detangling the issues of hyperlink vs. checkbox from those of single-select vs multi-select is particularly important.
Google Custom Search: More Layout Options (and no more iframe)
The Google free Custom Search Engine (CSE) will now require the AJAX Custom Search Element, and a Google Authorization code. I find the JavaScript in the Element opaque and frustrating, and I'm sure many people looking for simple search will have the same problems. The paid Site Search Engine (GSSE, aka GSS, GSE) can still get results in XML. Another aspect to note: there is no way to make either version of the search engine index pages with access control, user names and passwords. It's a very common question, and the answer is no.
Introduction to Search with Sphinx - O'Reilly Media
Definitive Sphinx book by the author of the program, with the benefit of O'Reilly editing.
Coreseek - Chinese version of Sphinx search engine
The page is mostly in Chinese so I can't really tell what's up, but it's clearly a version of Sphinx, and it says it's made by Beijing Choice Software Technology Inc. and has been around since 2006.
Flying Sphinx - full text search engine as a Heroku addon
Flying Sphinx is a service providing a Thinking Sphinx search engine deployed on Heroku (Ruby on Rails) cloud services. Rates range from $12 per month to $300 which includes 15GB of indexed data and near-real-time index updates. I think it's run by a very active Sphinx/Thinking Sphinx contributor. This is a link to the Heroku page, there's also a site: www.flying-sphinx.com
smartOCI cross catalog search engine with OCI 4.0 for SAP SRM application | NetSol Technologies
This seems to be a federated search on web-based supplier catalogs (b2b) using something called the Open Catalog Interface.
Search Analytics for Your Site: Conversations with Your Customers :: UXmatters
Chapter 8 of Lou Rosenfeld's book on site search analytics, full of practical advice. It contains lots that's useful for intranet and enterprise search as well.
Yahoo! Search BOSS group
[Yahoo Build your Own Search Service] BOSS V2 Updates
New features include daily limit controls, HTTPS, SQL and YQL support, more news content, and better documentation. Note that BOSS v.1 will go away on July 20, 2011.
Sometimes I Wish NLP Systems Occasionally Blew Up - LingPipe Blog
Like search, badly performing Natural Language Processing systems tend to be quietly bad, rather than flaming out. Great quotes: "NLP Systems are Easier to Sell than Build", "Customers get the potential value of advanced NLP/Text Analytics/etc in the same way that people get the potential value of space flight." and "Be aware that you are selling to the best NLP systems out there: Humans", "It is unrealistic to expect a named entity model to perform well on Twitter if its training data is the 1994 Wall Street Journal."
How to Make a Great Search Results Page (short ecommerce overview)
Intro to search on online stores, this says that analytics should show at least 55% of visitors using site search (that seems a little high to me). There's a little bit about size and placement of search fields and general suggestions on relevance and elements of search results.
Open Source Web Mining Toolkit | Bixo
Includes solid crawler code, Hadoop to store the URL database, Cascading pipeline and scheduler, and Tika to read the pages.
A Workshop on Restructuring Adjectives in WordNet
WordNet is the most widely-used English-language lexical database. This US government grant is to add coding values for dimensional (amount) adjectives. Apparently there's a recently-developed AdjScales system? Anyway, anything that adds to WordNet is a good thing by me. (via Ross Stapleton-Gray)

"401 unauthorized access" when server-side code or browser tries to call itself with URL - imason blog
Using a load balancer with two SharePoint servers sometimes returned a 401 error because the real hosts were authorized but the load host was not. I always wonder how these things show up, here's one cause.
Search Is Not Just an IT Problem
Nice overview of the many issues of search strategy
[WordPress] Comment-Page-1 Pagination Creates 23 Million Duplicate URLs
The default setting of WordPress has two URLs for each post: the name and the name followed by /comment-page-1/. This article talks about how to tell search engines not to index this on the WordPress side. Search engines should just exclude URLs with that string.

The Changing Face of SERPs: Organic Click Through Rate Curve
Search engine marketing-oriented study by Optify of clickthrough rates depending on position of the item in search results. Fully 37% of all clicks are on the first result, 60% percent of clicks are on the first three or so, and very few on second and subsequent pages. They contrast this with sponsored results Cost Per Click and the ultimate business results.
Q-Senesi Enterprise Search Engine
A new search engine for intranets, web sites and analytics. It has been running for a while as a bookfinder and web data search engine and now is being developed as a standalone product. However, there seems to be no robot crawler or spider and the structured data configuration is quite tedious. I also couldn't find a price anywhere.
Search as middle-ware at att.com, with Shantanu Deo - Coté's People Over Process
Informal conversation starts with AT&T's CMS and goes on to talk about using Solr for catalog search on the site. It started as a bit of a skunkworks, and takes very little maintenance and few resources.

Exploring synonyms within large commercial site search engine queries [HP Research Report]
Straightforward study of hp.com's queries finds that reformulations and clickthrough data are not good ways to find synonyms, but that starting from lists of product names is promising. Spellchecking for typos and spacing, and pluralization reduce the need for synonym listings. It also recommends a larger data set than their 190,000 query log. (via Martin White, @IntranetFocus)

How Google Instant’s Autocomplete Suggestions Work - SearchEngineLand
Danny Sullivan's detailed look at how Google's auto-complete and instant search, which seems to be populated by a combination of many recent searches and long-term frequent searches.  They have an inconsistent policy on removing negative terms from the suggested list.  He thinks they should just remove them without fuss.   These examples emphasize how enterprises and web sites should keep very strict control over their autocomplete (and spelling) suggestions, rather than rely on technology.
Error-Tolerance and The Long Tail of Search in Ecommerce « Exorbyte Blog
In e-commerce, it's much better to find something than nothing.  Spellchecking and other tools for inexact matching can improve results for the long tail of unique and near-unique queries.  Exorbyte reports increases of conversion from 5% to 20% - at least somewhat related to their error tolerance.
A Vision for Unifying Access to Data and Documents - Forbes [Attivio]
Describes Attivio's combination of unstructured and structured data for a new kind of BI. ... entity data and the sentiment analysis and other analysis techniques become part of the meta data for the unstructured data. This allows the unstructured data to be presented as structured data. You can do relational joins between the structured and unstructured data to answer questions like: “Find all negative product reviews that mention both the iPad and our top-20 best sellers.”
MagnetStreet attracts sales with improved site search - Internet Retailer (SLI systems)
Consumers using site search browse about 11 more pages per visit than shoppers who don’t, and remain on the e-commerce site  nearly 13 minutes longer.
Autonomy IDOL Universal Search product page
"IDOL Universal Search provides users with a simple, personalized search experience tailored specifically to their unique requirements. In many typical environments, content may be spread across disparate internal data repositories and systems as well as external content sources and engines. Users are forced to conduct multiple, repetitive searches or risk missing crucial information. With Universal Search, a single query quickly federates unified results across systems in an intuitive, easy-to-navigate Web interface. Users get the big picture quickly through advanced visualization and dynamic categorization for a faster, more thorough exploration of results."
Incompetent Research Skills Curb Users' Problem Solving (Jakob Nielsen's Alertbox)
Results from a usability test - only 1% of the time did users change search strategy.  So search engines need to concentrate on improving reliability of simple search results.
Interaction Models for Faceted Search « Information Interaction
Tony Russell-Rose does a great job identifying various models of faceted search interactions, including the relations between the facets, Smart Dead Ends, the relative values of "instant update" and "two-stage" matching and user choice, multi-select AND vs. OR, and interstitial pages.  Very valuable analysis and naming.

How do I create a CSE that searches the entire web? - Custom Search Help
Google will let you search the whole web, though the results will be different from those of google.com, and you can only get the first 100 results.  Usage is free up to 100 queries per day, with Google-supplied advertising, after that, it's available at approximately $5 per 1,000.
Who judges what "good" search results are?
Mary Ellen Bates and Chris Sherman show how info pros and researchers differ from search engine optimizers in evaluating search results.  For research, recall is better and two good matches on the first page is a good result.  For SEOs, 80% of the first page should be useful: more emphasis on precision.  Good reminder about variations in search requirements.

Secure Search in Enterprise Webs: Tradeoffs in Efficient Implementation for Document Level Security
Useful research - dependence of query processing time on result set size and visibility density for different classes of user. Scaled up to collections of tens of thousands of documents, our results suggest that query times will be unacceptable if exact counts of matching documents are required and also for users who can view only a small proportion of documents. We show that the time to conduct access checks is dramatically increased if requests must be sent off-server, even on a local network, and discuss methods for reducing the cost of security checks. We conclude that enterprises can effectively reduce DLS overheads by organizing documents in such a way that most access checking can be at collection rather than document level, by forgoing accurate match counts, by using caching, batching or hierarchical methods to cut costs of DLS checking and, if applicable, by using a single portal both to access and search documents.
Developing a SharePoint 2010 Strategy. . . or How Setting It Up and "Getting It Out There" Is Not a Strategy
A synthesis of many cases where Sharepoint has been implemented so haphazardly that the results complex structures and frustrating user experiences.  Jeff Carr identifies key components for success with SharePoint: purpose, governance, people & objectives, requirements, IA, technology, and maintenance.

HICR person - Gene Golovchinsky, Ph.D.
My other area of interest relates to Human-Computer Information Retrieval (HCIR). I have designed, implemented, and evaluated a variety of interfaces for browsing and exploring document collections. I have focused on novel interaction techniques including dynamic hypertext, query-mediated browsing, implicit queries based on annotations, and lately (working with Jeremy Pickens), on Collaborative Exploratory Search. I have published extensively in information seeking and collaborative exploratory search, and have co-organized several workshops on information exploration (at CHI98 and SIGIR98) and collaborative search (at CSCW98, JCDL 2008, and coming up at CSCW 2010).
Autocomplete for semantic content - live example
Semantic autocompletion  "Autocompletion can help user with quickly finding terms from a data source. To effectively support autocompletion on large sources the algorithm and result presentation should be optimised for the specific task." Michiel Hilebrand, Alia Amin and Jacco van Ossenbruggen, investigated the design space of autocompletion and methods to support configuration of autocompletion widgets for RDF.

Why Google Can't Count Results Properly (on web search, site search, or CSE)
Danny Sullivan discusses the unreliability of Google search results counts, and quotes Matt Cutts of Google: [Adding more search terms] "causes us to go deeper through our posting lists looking for matches, which can lead to more accurate (and larger) results estimates. Other things can cause us to go deeper in finding matches, such as clicking deeper in search results. Results estimates can also vary based on which data centers or indices your query hits, as well as what language you're searching in." Avi says: This is not a really helpful answer, especially for Google Custom Search Engine (free search service) and the paid Site Search version.  It's terribly confusing in those cases.
Webinator Search Engine v. 6 changes (Thunderstone)
This version adds an internal federation option, XML, SOAP interface, authorization controls, customizable thesaurus, group by site and other new features.

How Far Does Semantic Software Really Go?
Lynda Moulton describes the challenging configuration and management of integrating semantics into search engines. "Semantic search operates best when it focuses on a topical domain of knowledge. The language that defines that domain may range from simple to complex, broad or narrow, deep or shallow. The language may be applied to the task of semantic search from a taxonomy (usually shallow and simple), a set of language rules (numbering thousands to millions) or from an ontology of concepts to a semantic net with millions of terms and relationships among concepts."

boilerpipe - removes clutter around web page content (java code library)
The boilerpipe library provides algorithms to detect and remove the surplus "clutter" (boilerplate, templates) around the main textual content of a web page. The library already provides specific strategies for common tasks (for example: news article extraction) and may also be easily extended for individual problem settings. Extracting content is very fast (milliseconds), just needs the input document (no global or site-level information required) and is usually quite accurate. Boilerpipe is a Java library written by Christian Kohlschütter. It is released under the Apache License 2.0. The algorithms used by the library are based on (and extending) some concepts of the paper "Boilerplate Detection using Shallow Text Features" by Christian Kohlschütter et al., presented at WSDM 2010 -- The Third ACM International Conference on Web Search and Data Mining New York City, NY USA. Click here to read the paper and the presentation slides. A video of the presentation is freely available on Videolectures.net (turn speaker balance to the left to improve audio quality).

What makes relevance such a challenge in the enterprise? (sharepoint & fast search blog)
Nice overview of why internal search is often worse than web search: mainly that there's little meaningful linking within an intranet, little incentive to make a site easily searchable, and security issues with access control.  The post recommends realistic expectations, not indexing low-value content, looking at third-party relevance tools, offering scope or zoned search, and tagging content.

general about issues of access control and relevance ranking not even hinting about the existence of invisible documents.  Inverse document frequency can give hints, therefore they are doing it on metadata but not on body text, they say it doesn't hurt relevance.
Palantir Blog: search with a twist (part one: memory efficiency)
Palantir Business Intelligence uses the Lucene core search engine, but not for simple web-style search.   They say "We want to leverage the inverted index capabilities of Lucene, but our data access patterns are a bit different than the typical use case: we need things like pervasive range-querying, different types of relevance, and dynamic views of the data based on security constraints."  But for queries with binary answers, a document is in the result set or is not, they found a more efficient way than Lucene 2005's memory usage approach.

Extrapolating about search getting smart to the point of precognition brings up important issues of control and privacy.  Gord Hotchkiss, who has done a lot of behavioral research, thinks that humans would rather be guided by search than have our choices taken away. I suspect that he's right, as he points out that even B2B procurement automation never quite took off.

Taxonomy Fairy Tales (video)
Patrick Lambe and Matt Moore discuss why internal and enterprise search engines don't work as well as web search, due to a lack of meaningful hypertext links and different expectations (I agree).  They mention the value of taxonomies for improving search, and the fact that there is no Taxonomy Fairy or magic automated system to organize things.  And they recommend that most of the taxonomy come  from the bottom up, by categorizing stuff and seeing how it fits together.  Very engaging and I'm glad that I agree with them.
Google Search Appliance - Open Source Projects
6.2 Administering Crawl for Web and File Share Content: Introduction - Google Search Appliance
For both scheduled crawls and continuous crawls, documents usually appear in search results approximately 30 minutes after they are crawled. This period can increase if the system is under a heavy load, or if there are many non-HTML documents.
Comparing the Sensitivity of Information Retrieval Metrics - Microsoft Research
"Information retrieval effectiveness is usually evaluated using  measures such as Normalized Discounted Cumulative Gain (NDCG), Mean Average Precision (MAP) and Precision at some cutoff (Precision@k) on a set of judged queries. Recent research has suggested an alternative, evaluating information retrieval systems based on user behavior. Particularly promising are experiments that interleave two rankings and track user clicks. According to a recent study, interleaving experiments can identify large differences in retrieval effectiveness with much better reliability than other click-based methods. We study interleaving in more detail, comparing it with traditional measures in terms of reliability, sensitivity and agreement. To detect very small differences in retrieval effectiveness, a reliable outcome with standard metrics requires about 5,000 judged queries, and this is about as reliable as interleaving with 50,000 user impressions. Amongst the traditional measures, NDCG has the strongest correlation with interleaving. Finally, we present some new forms of analysis, including an approach to enhance interleaving sensitivity."

Breaking the Web with hash-bangs
JavaScript applications tend to use weird URLs to save their state, and have been doing this with # hash fragments.  However, these do not translate well to search spiders and indexers, so Google came out with the #!

SharePoint Partners Can Plug Taxonomy Gaps - [paid report from] Forrester Research
Just knowing that MOSS is bad at metadata & taxonomy management is useful.   Summary: "Microsoft Office SharePoint Server 2007 (MOSS 2007) has lousy metadata capabilities. If tagging content and managing taxonomies in MOSS 2007 are important to you— and they should be — consider buying a third-party solution to meet key requirements. SharePoint Server 2010 ships with significant metadata enhancements that could spur enterprises to upgrade. Yet even with these improvements, sought after semantic capabilities like autoclassification and entity extraction remain gaps in the SharePoint platform. Use this report as a guide to partners that can plug these important SharePoint 2007 and SharePoint 2010 gaps." $499 study
