Expertise Locator - builds and maintains profiles in a repository that can be queried directly by users to locate experts by skill, experience, project, education, job type and many other attributes. The profiles are created through a variety of measures: drawing demographic data drawn from any LDAP directory; field mapping from specific applications such as teamrooms, discussions, and project tracking. The expertise locator also uses a metrics tool to determine affinities between subject matter and user activity to infer interests and expertise. Before adding this discovered content to an individual profile, Raven presents the end user with the update, which must be approved by him or her before it can be published and searched by the departmental or enterprise population.

Content Catalog - crawls text sources (including text about people) to identify subject matter topics. It analyzes content by looking for frequency, proximity to other topics, relationship to people and a host of other measures. From this information the content catalog groups similar content into browsable categories, called a content map, which it constantly maintains and updates as it receives new content and usage data. Raven's content catalog then derives people's skills from content they have authored or read and maps them to the categories alongside documents. The catalog continually analyzes new content to calculate usage patterns and relationships to determine the value and relevance of people and content to one another. By subscribing to specific categories that interest them, users can direct their knowledge portals to deliver to them relevant information about news, projects, people and organizational structure. Raven uses IBM's DB2 Universal Database as the underlying technology to manage the catalog and the complex analyses required to sift through millions of documents.

"Where Raven really shows promise is in the addition of expertise profiles. Again, these profiles start by crawling through the documents that each individual has posted. By mapping the topics discussed in these documents, Raven creates a person's expertise profile. By feeding ongoing document use into the expertise locator and allowing the expertise locator to better inform the categorization of documents, Raven promises to do something truly powerful.
