Wiki Tagging + Intranet Search Engine Ranking
Session in Room B, Monday, 20 Feb 2006, 2:30 - 3:45, session lead PeterThoeny
The larger a wiki gets, the harder it is to find content. Wiki tagging attempts to solve this issue.

Assertions
- Assertion 1: Search engines do not work well on intranets
- Assertion 2: Let the individuals build their own taxonomy to find content quickly
- Assertion 3: Let the users do the ranking to get an "human intelligence" ranking of important content
- Assertion 4: The intranet is a wiki
[edit]
Intranet Search Engine Ranking
Intranet search does not work well due to inadequate ranking of search engines on intranets. This is because there are typically not many cross-links between pages.
[edit]
Wiki Tagging
The design goals are as follows:
- Any intranet page can be tagged by individuals -> create taxonomy for individuals
- Show tag statistics of all users on each page -> show popularity
- Encourage users to reuse the same tag on a page -> get a "collective ranking", or "vote for a tag", or "tag count"
- Make it as easy as possible to increase the tag count
- Make it as easy as possible to add a new tag to a topic
- Encourage users to create new tags, but try to avoid use of different tags for the same subject
- Feed the "human intelligence" ranking back to the search engine for better ranking
TWiki has a Plugin for wiki tagging: http://twiki.org/cgi-bin/view/TWiki/TagMePlugin

- Wiki Tagging and Intranet Search Ranking
[edit]
1. Peter Thoeny opened the session with the assertion: In Wikis, Search doesn't work on an Intranet
- The reason is cross links are missing, and there are multiple targets for search on Internet but only a few, or one, for an Intranet
- ...matchupcamp.com has some keywords that are tags
- to get meaningful ranking for search you need more than keywords (Peter)
- ...a vote for a keyword or tag might be recorded
- ...perhaps tags about tags ...tag count for each tag, then can use these as weights
- ...an example: 'useability' tag value
- ...you could retain names of tag voters
- ...let guests vote one time
- ...then, search on tag 'Useability', show pages in order of pages voted with this tag
- ...Peter has created keywords example in the mashupcamp home page
- Clicking on a tag votes on utility or value of the page
- ...issue though: does vote mean tag is good for the page or page is what you wanted? So how this distinction be made? Would you ask the user to add tags and vote on tags?
- ...Point: anyone can change tags, even remove them, view is not personal
- ...with Wiki tags are shared not personal
- ...so tags will evolve to reflect concerns of the community
- ...Point: might be interesting to track the velocity of votes, direction
- ...what are our hot topics now? what were they then?
- ...to be high value meta data value add for the activity the right things have to bubble up to the top
- ...incentives might vary identity, personal reputation might be captured as well, certainly would be reflected if identity of voters is retained.
[edit]
Search
- How to use tags to help with the search problem? Another way, is there a need or a market to provide links between tagging and search in the enterprise? History of search is about discovering new forms of high value meata data
- ...page titles (metavista)
- ...Google with page link (backlinks)
- ...in theory social text doing same thing, providing social tagging as a way to provide metadata suggested tags
- ...tagging would be leveraged how bsides voting? How to rank based on voting? discussion: ranking tags even when weighted by votes results may be skewed especially if sample sizes are small voting history and tags you created might be combined with search methodology to get interesting results there are privacy issues as well, which results can you see? "every link is a vote for attention" could be useful to see external links outside the Intranet, what are we looking for/at? Q: assume WikI and Search are separate applications? A: every Wiki has its internal search, so these will be converging finding content in large Wikis is very hard, basically a matter of filtering
- ...the WikI will become your Intranet Wiki ageing another issue related to tagging perhaps, Peter cites a Wiki now 7 yrs old that contains much stale content
- ...page hit counts work, e.g. 'popular' or 'frequently used' pages
- ....HTML pages have keywords, these are tags and you leverage thoughs Point: on an Intranet why not use <meta> tags keyword lists, no spam issue here. Then could search these. Might be able to hold votes here too and also the time series of vote levels
- ..had 100 votes on <date> and <nnn> on <date2>
- Docs, files not on Wiki how would you tag these? this would probably become URL tagging like Delicious
- ...would enterprises want people spending time on tagging? consensus is time cost up front probably recouped later by being able to find material again some stikiness needed for this to work, like some message boards use.
- Lots of enterprises have Wikis of over 100,000 pages in a single Wiki manageability depends on how you partition it BP: use minimum no of webs, categorize in multiple ways, navigation model is by category
- ...Companies are moving intranets to WIKIs, some are being tagged
- ...Ross M, CEO SOcial Text, Wikis for enterprise collaborations wiki, weblog, email; Charlie S, started mapBuzz? Author of Kwik Wiki; Lugi, author of Clip Clip; Ag, Sapient Wiki for UN; Yong, John M, enterprise business process integration; John R SMB Wiki's; Arnold S, Central Desktop; Peter T runs TWiki.org and Structured Wikis LLC providing order to structured wikis behind firewalls
- ....Point, Peter Thoeny: Qiki is more of a match-up playground Social text is built on this
