More sophisticated would be a self-learning system that suggests tags based on current tagging patterns. Thus, if a user tags a document "foo," the application might return a message saying, "Eighty percent of users who tagged a document foo also tagged it barr. Would you like to tag the document barr?" No such capability exists today. Bringing it home
Usability also extends to the retrieval of bookmarked results. Optimally, those results should be integrated into the enterprise search engine and displayed alongside regular search results. While every product but Cogenzs Enterprise Edition returns bookmarked results within search results, only Connectbeam does so on leading enterprise search platforms Fast and Google. IBM and BEA use their own search engines, each of which has smaller market share than Fast or Google.
As for ranking bookmarked results, Connections, Application and Enterprise Edition all rank documents based on popularity: The more bookmarks referencing the page, the higher its ranking. But not all authors are equal, and treating results from experts and novices alike is deceiving. The same goes for the bookmarkers themselves: Experts should have more weight. To address these issues, BEA has developed an ActivityRank for each item and user in the system. Administrators can adjust the relative influence of each rank factor, such as authors and submitters ranks and the rank and number of people whove edited, bookmarked, tagged and viewed the document. Similar elements can be applied to the ActivityRank of individuals as well. BEAs solution can also expire links from old bookmarks, forcing inactive, top-ranked pages from dominating search results. Finally, all the products expose the tag cloud, revealing tags others have used. All but Cogenzs Enterprise Edition use bold and larger font sizes to indicate more popular tags. BEA officials say they are modifying the tag cloud to depict the relationship between content and user, a capability thats expected to be available in the first half of 2008. Bookmarking price It can be difficult to get a firm price on enterprise bookmarking systems, either because of additional software requirements or market pressures. To help get a better handle on the deal, eWEEK asked vendors to price out a two-site installation for 5,000 users. IBM Lotus Connections costs $110 per user for the first year with a yearly maintenance fee thereafter. So expect to spend at least $550,000 in the first year for our 5,000-user scenario, making Connections the most expensive of the products. Then again, Connections includes more functionality than the other players. And, if you average out that one-time charge across the five social software tools in Connections, the price compares favorably with competitors. AquaLogic Pathways costs $40,000 per CPU, or $64 per user and $80,000 for our 5,000-user scenario. Once again, thats not the full story, as additional BEA software is required. At the very least, AquaLogic Interaction will be needed for security and searches. Not surprisingly, the two startups do not require the purchase of sister software packages. Connectbeam charges a yearly fee with tiered pricing based on number of users, starting at $20 per user or $100,000 per year for 5,000 users. Cogenz charges $2 per user per month, or $120,000 in the 5,000-user scenario. Dave Greenfield is a 20-year networking veteran and the principal of Strategic Technology Analytics.
