Abstract: A system for analyzing text-based information is presented. Each datum of information includes an author, a description and a timestamp. A fetcher fetches the raw information according to keywords. A parser parses the raw information to refine the results. A lexicon management module extracts lemmas from the raw information, and creates an edited lexicon containing the raw data and the lemmas for each datum. A data manager correlates lemmas in the edited lexicon and identifies clusters of lemmas that are correlated between each other. The results can be visually displayed to a user, and clusters of lemma that are less correlated than the other clusters can be visually identified. In one aspect, the user is able to excise the less correlated clusters, in order to further refine the results of the keyword search.

Abstract: A sprinkler controller in a poultry house having a processor, a data storage device operatively connected to the processor, the data storage device having instructions for programming the processor, and an input/output module operatively connected to the processor. The input/output module is configured to communicate with at least one valve for controlling a flow of fluid between a fluid source and at least one sprinkler nozzle. The at least one valve has an open position permitting the flow of fluid, and a closed position inhibiting the flow of fluid, and the position of the valve being determined by the processor. The processor is programmed to set the valve in the open position at a start of an activity promotion interval, and to set the valve in the closed position at the end of the activity promotion interval. The duration of the activity promotion interval is selected such that a sufficient amount of fluid is dispersed through the sprinkler nozzle to promote physical activity in the poultry.
