has been developing software for automatic text analysis and search based on a system of knowledge organization since 1985. MITi's technology is marketed under the trade name READWARE®. The product line includes ConSearch for Windows workstations, the IpServer for internet/intranet applications and the Readware Software Development Kit for custom solutions. Abstract READWARE performs a fully automatic text analysis that implements a system of knowledge organization based on knowledge types. A knowledge type is a set of instructions that identifies a set of knowledge elements in any text. Knowledge types include concepts (word sets), topics (an expandable hierarchical scheme of common knowledge types spanning politics, business, health, and so on), probes (investigative knowledge types), issues (knowledge types used in decisionmaking) and document subjects (traditional classification of documents by themes). An MITi analyst used this system to translate TREC topic specifications into highly selective queries (few hits per query) in two adhoc runs with high relevance rates (2019 / 3060 hits in the READWARE run and 2774 / 5785 hits in the READWARE2 run).
