Today we continue our discussion on Hearst's paper on text data mining. We were discussing the LINDI project. The objectives of the LINDI project are to investigate how researchers can use large text collections in the discovery of new important information, and to build software systems to support this process. The main tools for discovering new information are of two types: 1) support for issuing sequences of queries and related operations across text collections. and 2) tightly coupled statistical and visualization tools for examination of association among concepts that co-occur within retrieved documents. Both set of tools make use of attributes associated with text collections and their metadata. That is why integration is recommended between the tools.
User and system interact iteratively. System proposes new hypotheses and strategies for investigating these hypotheses, and the user either uses or ignores these suggestions and decides on the next move.
In this project, newly sequenced genes are discovered by automation. Human genome researchers perform experiments in which they analyze co-expression of many new and known genes simultaneously. Given this, the goal is to determine which of the new ones are interesting. The strategy is to explore biomedical literature and come up with hypotheses about which genes are of interest.
In tasks like this, the user has to execute and keep track of tactical moves and repeat them often distracting from reasonings. This project provides a facility for users to build and so reuse sequences of query operations via a drag and drop interface. They allow the users to repeat the same sequence of actions for different queries.
The operations include :
Iteration of an operation over the items in a  set.
applying an operation and returning a transformed item.
applying an operation and returning an ordered set of items.
applying an operation and returning a selected set of items
applying an operation and returning a singleton result.
